DETAILED DESCRIPTION - FIG. 1 illustrates an embodiment of an occupancy sensing system according to some inventive ideas of this patent disclosure. The embodiment of FIG. 1 consists of a computer workstation 10 and an occupancy sensor 12 arranged to watch a space 14 associated with the pc workstation for a number of occupants. The occupancy sensor 12 generates an occupancy sign in response to monitoring the space. A connection sixteen between the occupancy sensor and the computer workstation enables the computer workstation 10 to course of the occupancy signal and carry out one or more power administration functions in response to the occupancy signal. A computer workstation (or "computer" or "workstation") refers to a mix of input, output, and computing hardware that can be utilized for work or leisure by an individual, and consists of desktop computers, notebook computers, terminals linked to networks, and so forth. The computing hardware could include a central processing unit (CPU) to execute program instructions. The workstation could course of the occupancy signal from the occupancy sensor with software that uses CPU cycles to carry out its features. Processing the occupancy sign may be carried out as a low priority course of on the CPU. Implementing the occupancy sign processing as a low precedence process could integrate nicely with different CPU processes because, if the workstation is in use and different higher priority course of are operating, there isn't a concern that the low priority occupancy signal processing is slowed down. Nonetheless, if the occupancy sensor is checking for occupancy, then the workstation is unlikely to be in use, and free CPU cycles can be found. Furthermore, processing the occupancy signal with workstation CPU cycles can also enable the processing energy of the occupancy sensor to be lowered, thereby lowering its value. The occupancy sensor 12 has a subject of view 18 that allows it to watch the house 14 associated with the computer workstation. The occupancy sensor 12 may be based mostly on any appropriate sensing know-how akin to passive infrared (PIR), ultrasonic (U/S), audio, video, and so on., or any combination thereof. FIG. 2 illustrates another embodiment of an occupancy sensing system in line with some inventive rules of this patent disclosure. FIG. 3 illustrates another embodiment of an occupancy sensing system according to some inventive rules of this patent disclosure. The embodiment of FIG. Three is much like the embodiment of FIG. 1 however in the embodiment of FIG. 3, the workstation 24 includes functionality 26 that permits a person to regulate a parameter of the occupancy sensor on the workstation. The adjustable parameter may embrace a time-out delay, sensitivity setting, and many others., for the occupancy sensor. The connection 32 may be integral with the connection 16 that carries the occupancy sign, or it could also be a separate connection. FIG. Four illustrates one other embodiment of an occupancy sensing system in line with some inventive rules of this patent disclosure. The embodiment of FIG. Four is just like the embodiment of FIG. 2 however the embodiment of FIG. 4 contains load monitoring apparatus 34 that permits the workstation 36 to monitor a number of hundreds via a connection 38 to the workstation. The load monitoring apparatus 34 may be separate from, or integral with, energy swap 20, and permits the workstation to find out power, voltage and/or present levels, in addition to on/off standing and different parameters of an electrical load. FIG. 5 illustrates an embodiment of a computer workstation in keeping with some inventive principles of this patent disclosure. The workstation forty two of FIG. 5 features a display forty four and a CPU 46. An occupancy sensor 48 is mounted to the show to facilitate monitoring the area related to the workstation. The occupancy sensor forty eight could also be separate from, or integral with, the show 44, and could also be primarily based on any appropriate sensing expertise. The occupancy sensor forty eight generates an occupancy signal which is transmitted to the CPU 46 by way of a connection 50, which may be carried out with any appropriate wired or wireless connection. FIG. 6 illustrates an exemplary embodiment of a pc workstation in line with some inventive rules of this patent disclosure. The workstation fifty four is shown divided into hardware and software elements. As explained above, the working system 56 typically includes inside power administration options 88 that can be configured to turn off various pieces of hardware to reduce energy consumption when the workstation is just not being used. The inner energy management features 88 constructed into the operating system work on the assumption that the workstation is now not in use when no consumer inputs in the form of key presses or mouse movements have been obtained for a predetermined time period. Basing power management choices on the period of time with out user inputs to the workstation, nevertheless, usually results in incorrect assumptions that end in devices being turned off and/or the workstation being locked down while the person is still current at the workstation. Moreover, if the consumer does depart the workstation shortly after the last consumer enter action, the workstation may be left unattended, totally powered, and unsecured during your complete time-out durations set for the assorted components. The application software 58 may embody internal energy administration performance 78 that makes decisions in response to the actual presence or absence of a user on the workstation reasonably than assumptions primarily based on the amount of time without user input actions. The internal energy administration functionality 78 determines the state of an occupancy signal from an occupancy sensor 28 by way of a USB port sixty eight and makes use of this information to make decisions on when to turn off power to various pieces of hardware, place the workstation in a suspend, sleep or hibernate mode, and/or lock down the workstation and require the consumer to re-enter a password. Utilizing an occupancy sensor to manage the inner power management capabilities of a workstation might cut back power consumption and/or enhance workstation safety. For instance, occupancy sensors that use ultrasonic sensing know-how are likely to have good sensitivity to the "small motions" which might be typical of an individual working at a desktop, and due to this fact, could provide an correct indication of the presence of an occupant at a workstation. Therefore, the timeout delay for the occupancy sensor 28 could also be set to a comparatively quick period of time, e.g., a couple of minutes, with out producing false indications of an unoccupied situation on the workstation. This may occasionally end in reduced power consumption and improved safety as a result of the display, arduous drive and other hardware may be turned off and the workstation locked down shortly after the consumer leaves the workstation. Moreover, using an occupancy sensor to regulate the interior power administration functions of a workstation may cut back or remove instances wherein hardware is turned off and/or the workstation locked down though the consumer is still current at the workstation. The applying software program fifty eight may also include software to interface the workstation to a lighting management system or different constructing automation system through the community interface card 76 or by another appropriate interface. The consumer interface software eighty may additionally enable a person to configure which internal and external power administration actions to absorb response to the occupancy sensor 28 comparable to turning off the show sixty two or exhausting drive 64, inserting the workstation in a low energy mode corresponding to sleep, suspend, hibernate, and many others., locking down the workstation with password safety, turning off switched receptacles in one or more energy strips 89 and 90, turning off external gear with in-built energy administration functionality reminiscent of printer 92, or communicating with a lighting management system or other constructing automation system by the community interface card. The user interface can also enable the consumer to configure the applying software to turn off inside or external hardware immediately upon receiving an unoccupied indication from the occupancy sensor, or after a number of further time delays. Varied further time delays may be used to stagger the occasions at which totally different pieces of hardware are turned off, as well as when they're turned again on to prevent extreme energy surges when the presence of a person on the workstation is detected again. The user interface can also enable a consumer to process and/or view the power consumption of the workstation and/or any peripherals having power monitoring capability in real time, as properly has historic data of power consumption to search for patterns that will provide indications of how to attain additional power financial savings. The consumer interface can also allow the person to configure the system to report energy consumption information to a lighting management system or different building automation system for further processing and evaluation. The applying software program could also be implemented with an application programming interface (API), thereby enabling it to hook, and be hooked by, different software program. Some of the appliance software functionality may be implemented with a consumer interface that's much like a normal screensaver, and one or more parts of the applying software could also be chosen from a screen saver portion of the operating system. Nevertheless, the configuration and different hooks could also be explicit to the occupancy sensing and power switching devices and their own resident programs. The inventive principles usually are not limited to example implementation details proven in FIG. 6. For instance, the connections made by means of the USB ports and NIC may be carried out with wireless connections akin to Bluetooth, or could use different wired connections akin to DisplayPort or HDMI connections. Energy line communication (PLC) connections could also be used to communicate with power switches in power strips or in switched receptacles situated in wiring devices close to the workstation. Furthermore, switched power receptacles may be built-in straight into the workstation to control energy to peripheral devices in response to an occupancy sensor that's related to the workstation. FIG. 7 illustrates an embodiment of a dialog field for implementing a user interface in response to some inventive principles of this patent disclosure. The dialog box ninety four contains graphical "slider bars" for setting the sensitivity, field of protection (in terms of viewing angle) and time-out delay for an occupancy sensor that is able to receiving adjustable parameters. The dialog field also consists of check bins to specify which internally managed hardware resembling displays (displays) and exhausting drives, as well as which externally controlled hardware akin to power strips, must be turned off in response to the occupancy sensor. FIG. 8 is a block diagram of an embodiment of an occupancy sensor in line with some inventive ideas of this patent disclosure. The occupancy sensor 96 contains a number of sensors 98 based mostly on any suitable sensing technology or applied sciences. A controller 100 processes uncooked indicators from the a number of sensors 98 and generates an occupancy sign which is transmitted via a USB port 102. Typical sensitivity and time-out delay controls 104 could also be included to allow the controller to regulate the occupancy sensor for the particular area it is configured to monitor. Alternatively, or moreover, the controller could alter the occupancy sensor in response to adjustable parameters that it receives through the USB port 102. A number of indicators 106 may be included to display the occupied/unoccupied standing as determined by the occupancy sensor. For instance, a tri-colour LED may be configured to show pink for an unoccupied situation, green for an occupied condition, and yellow for a fault situation. A "wake now" input permits a user to take the system out of unoccupied mode if the sensor doesn't detect when the person returns to the workstation. Electronics in the occupancy sensor or software software program within the workstation could increase the sensitivity setting of the occupancy sensor every time the wake now button is pressed, since this may indicate that the sensitivity setting is simply too low. FIG. 9 is a block diagram of an embodiment of a energy strip according to some inventive rules of this patent disclosure. The facility strip one hundred ten of FIG. 9 receives input power from a connection 112 which may include a plug-and-cord meeting, connector prongs to plug instantly right into a receptacle, and many others. A predominant swap and/or circuit breaker and/or surge arrestor 114 receives the enter energy which is distributed on to a first set of receptacles 116 which might be energized when the ability switch 114 is closed. The workstation interface 130 allows the facility strip to communicate with a workstation by means of a wired or wireless connection using any suitable interfacing association. The facility monitor circuit 128 might embody any suitable circuitry to observe the voltage, current, power, and many others., of any load linked to any of the switched or unswitched receptacles. In some embodiments, a commercially available meter chip may be used together with a present sense transformer and voltage sense leads to provide a low-price solution that may be easily built-in into the facility strip. The user interface 126 might embody any kind of inputs and/or outputs to enable a consumer to configure and/or control the facility strip, enter parameters, test the standing or performance history of the ability strip, and so forth., from the ability strip itself. The person interface could include one or more input gadgets reminiscent of a potentiometer or different analog input, digital switches of any sort together with DIP switches, toggle switches, rotary switches, and many others. The user interface might include a number of output gadgets similar to lights, LEDs, numeric displays, alphanumeric shows, dot-matrix displays, and so on. The consumer interface may be configured to allow a user to set one or more time delays that management the operation of the switching circuit as described below, in addition to communication protocols, and/or additional time delay, and/or every other parameters. The communications with the workstation may be only one-approach to regulate a number of units of switched receptacles, or bi-directional to enable reporting of energy monitoring information to the workstation. In some embodiments, the controller 124 in the power strip could also be configured to turn each units of switched receptacles one hundred twenty and 122 on or off at the same time as quickly as it receives a command from the workstation. In different embodiments, the controller could delay turning one in all the 2 units on or off to avoid energy fluctuations, surges, etc. Alternatively, the different sets of switched receptacles a hundred and twenty and 122 may be controlled by different commands from the workstation which can embrace logic for staggering load flip-on and switch off, or for controlling the two sets of receptacles in a different way in response to totally different occupancy conditions at the workstation. For instance, totally different loads could also be turned on or off in response to completely different occupancy sensors in a multi-sensor arrangement as described below. FIG. 10 is a perspective view of an instance embodiment of an occupancy sensor based on some inventive rules of this patent disclosure. The embodiment of FIG. 10 may be used, for instance, to implement embodiment of FIG. 8. The occupancy sensor of FIG. 10 features a compact housing 132 to facilitate easy mounting on a workstation show. The front of the housing contains two ultrasonic transducers 134 and 138 which might be mounted on a convex surface to supply a defined protection sample (subject of "view") for ultrasonic occupancy sensing. A mini USB port 140 permits the use of a regular USB cable to attach the occupancy sensor to a USB port on the workstation. A removable panel 142 conceals commonplace management dials for sensitivity and time-out delay settings. A pushbutton 144 could also be used to implement the "wake now" characteristic described above. In some embodiments, the protection pattern of the occupancy sensor could also be adjusted by disabling one of the transducers, or by offering different weighting to the outputs from the transducers to implement a beam forming technique. The occupancy sensor of FIG. 10 could also be mounted in any appropriate location using any appropriate approach reminiscent of clips, magnets, two-sided tape, hook-and-loop fasteners reminiscent of Velcro, and so on. In some embodiments, a devoted communication cable for connecting to a workstation may be permanently hooked up to the housing using a pressure relief. Alternatively, or along with a USB port or permanent cable, a wireless interface using radio frequency (RF) or infrared (IR) know-how could also be included for communication with the workstation. An Infrared Information Association (IrDA) appropriate interface 148 is proven in FIG. 10 to implement IR communications. RF communication could also be completed with an antenna that's inside to the housing if the housing is made from plastic. FIG. 11 is a perspective view of an instance embodiment of a energy strip according to some inventive ideas of this patent disclosure. The embodiment of FIG. Eleven could also be used, for instance, to implement the embodiment of FIG. 9. The ability strip of FIG. Eleven features a housing 150, a plug-and-cord assembly 152, a most important energy change 154, an IrDA receiver 158, and a kind-B USB port 156 for connecting the ability strip to a pc or other gear. Two sets of receptacles 160 and 162 are de-energized when the principle energy swap 154 is within the OFF position. FIGS. 12 and thirteen illustrate a aspect elevation view and a prime plan view, respectively, of an example of the protection sample 164 which may be achieved with the occupancy sensor of FIG. 10. The occupancy sensor 131 is mounted to the highest of a workstation display 166 that's situated on a desk 168. In this instance, the workstation CPU is included within the display 166 and is managed by keyboard 170. As seen in FIGS. 12 and 13, the coverage pattern 164 consists of the consumer's chair 172 and different areas associated with the workstation that the user is prone to occupy whereas actively working at the workstation. These areas embrace a printer 174, a job lamp 176 and a space heater 178. The coverage sample is typical of the sample that may be achieved with a two-transducer ultrasound system. This sample could also be altered by turning off or weighting the outputs from a number of of the transducers as described above, or through the use of different occupancy sensing technologies. FIG. 14 is a prime plan view of a workspace associated with one other embodiment of a workstation occupancy sensing system in line with some inventive principles of this patent disclosure. The workspace of FIG. 14 is an office having a door 180, a desk 182, a chair 184 for the office's foremost occupant, customer chairs 186, and a whiteboard 187. A workstation show 188 has two occupancy sensors 190 and 192 which might be mounted on top of the show and connected to the workstation by way of USB cables or other kinds of connections as described above. The primary occupancy sensor 190 has a coverage sample 194 that is mostly intended to incorporate only the house that is likely to be occupied by the primary occupant of the workplace whereas working alone. Each of the occupancy sensors 190 and 192 may be related to the workstation and configured and operated as described within the context of programs having a single occupancy sensor as described above, however with separate settings and actions defined for each occupancy sensor. For example, room lighting or house heating in the office possibly turned on in response to either of the two occupancy sensors detecting an occupied condition, whereas the show, and any job lighting, printer, or other peripherals located on the desk 182 may only be managed in response to the occupancy sensor 190 having the protection sample 194 that includes the desk area. FIG. 15 illustrates one other embodiment of an occupancy sensing system in line with some inventive principles of this patent disclosure. The embodiment of FIG. 15 includes a number of workstations 200, each workstation having an occupancy sensor 202 related to the workstation utilizing any of the strategies described above. Every workstation also has not less than one building mild fixture 204 that illuminates the house related to the corresponding workstation. The circulate of power to the constructing lights is managed by a load control system 206 in response to commands obtained from a building automation server, workstation, or different controller 208. The load control system 206 and building automation or lighting system controller 208 and workstations 200 are connected to a constructing community 210 via community adapters 212, 214 and 216, respectively, in addition to their own particular person network interface playing cards. The building community 210 may be applied with Ethernet, CAN or other sort of network appropriate for constructing automation, vitality administration, and many others. The load control system may be carried out with a relay cabinet, dimmer rack, distributed relay/dimmer system, and so forth., or another network connected load management gadget. The building automation controller 208 provides the general operational logic for the system. When the controller 208 receives a message from one of many workstations indicating that the associated occupancy sensor has detected an unoccupied condition for the related space, it issues a command to the relay cabinet instructing it to show off the light for the space related to that workstation. Upon receiving a sign from a workstation that the associated space is once once more occupied, the controller indicators the relay cabinet to revive power to the sunshine for that area. A potential benefit of the system illustrated in FIG. 15 is that it could enable lighting and other building automation techniques to higher accommodate occupants in cubicles or other relatively small areas. Traditional lighting control methods and different constructing automation systems usually employ ceiling or wall mounted occupancy sensors. Cubical spacing requires more densely placed sensors with proper alignment complicated by the location of overhead lighting fixtures, heating ventilation and air conditioning (HVAC) gear, sprinklers, and so on. Moreover, the frequent rearrangement that is common with cubical areas presents a further challenge to proper alignment of occupancy sensors. The inventive principles referring to workstation-primarily based occupancy sensor programs described on this patent disclosure, however, might scale back or get rid of these issues as a result of the occupancy sensor for each workstation and its associated workspace could also be positioned very easily in a close location that reliably screens the world most likely to be occupied by the workstation user. Furthermore, the inventive ideas may cut back the price and uncertainty associated with mounting numerous occupancy sensors on ceilings or walls of buildings. In embodiments wherein a workstation is networked to a lighting control system or different building automation system, the application software program might implement a blink warning override function. For example, the lighting management system may be configured to show off the lights in a building space in response to a timer-based mostly vitality conservation schedule. In such a configuration, the lighting control system usually turns the lights off briefly (a "blink warning") prior to really turning off the lights to notify occupants of the impending automated flip-off. After the blink warning, the lights are held on lengthy sufficient to allow occupants to leave the realm or enter a request to the lighting management system to keep the lights on. Inputting a request usually requires the occupant to find a management station for the lighting management system. The nearest management station could also be a considerable distance from the occupant's workstation. In response to some inventive ideas of this patent disclosure, the applying software program might mechanically notify the lighting control system that the space associated with the workstation is occupied, and subsequently, automatically override the blink warning for the light or lights that illuminate the area associated with the workstation. Alternatively, or as well as, the applying software program might receive a message from the lighting control system when a blink warning is imminent, and current a pop-up message or dialog field to the occupant advising the occupant of the impending blink warning. This will likely simply notify the occupant of the blink warning event, or the occupant could then be allowed to elect by the workstation to override the blink warning, or to allow the blink warning to proceed as regular. In embodiments through which a workstation is networked to a lighting control system or other building automation system, the applying software may additionally present other override options. For instance, if the lighting control system is configured to show off the lights in a building area in response to a timer-primarily based vitality conservation schedule, the application software program could request that the lighting control system maintain the lighting in the house related to the workstation, no matter any blink warn performance. The maintained lighting may include not only the house associated with the workstation, but in addition any associated areas to allow for egress from the house. The application software program might also be configured to allow or override an attempt by a networked building automation system to sweep off power receptacles within the space related to the workstation if the occupancy sensor signifies that the area is occupied. The sweep-off performance may be built-in with, or separate from the blink warning override performance. In embodiments by which a workstation is networked to a lighting management system or other building automation system, the application software may additionally provide load monitoring information to the control or automation system if there is any load monitoring apparatus connected to the workstation. This will allow the lighting management system or different building automation system to judge the effectiveness of the occupancy sensing and cargo control performance of the workstation-primarily based occupancy sensing methods, as well as their interaction with different building automation programs. In areas the place a handheld or different distant management is used for native control of lights in a lighting control system or other building automation system, a workstation having an occupancy sensor related could also be further related to the remote control as a strategy to interface the workstation to the control or automation system. For example, an present handheld distant management might provide on/off and dimming control of overhead lights by means of an IR receiver in a digital wall change or photocell system. A further wired or wireless connection may be created between the handheld remote and the workstation to allow the workstation to manage the lighting in response to the occupancy sensor by way of the handheld distant, thereby eliminating the need for a network connection between the workstation and the lighting control system or constructing automation system. Alternatively, a wireless connection could also be created straight between the workstation and the receiver that's used by the handheld remote, thereby allowing the workstation to communicate directly with the lighting management system through the prevailing system components and without the need for an extra network connection. The strategies and apparatus described above enable the implementation of numerous features according to the inventive rules of this patent disclosure. Some example implementation details are described beneath for instance the various features and benefits that may be realized. The inventive principles, nevertheless, are not restricted to those instance particulars. Though any suitable occupancy sensing technology, or mixture thereof, could also be utilized, ultrasonic sensing could also be particularly nicely suited to the small spaces and small motion that may have to be detected for occupants performing workplace work in a cubicle. Mounting the one or more occupancy sensors on a workstation show may provide excellent converge as a result of workstation customers usually arrange their total workspace around the display. Using an occupancy sensor that generates a conventional occupancy signal that provides a binary occupied/unoccupied indication may simplify implementation and enable using current occupancy sensing circuitry which has been subjected to extensive troubleshooting, high quality tuning and cost discount. Nevertheless, different varieties of occupancy sensors that provide more uncooked output such as the unprocessed output from an ultrasound transducer or infrared pyrometer could also be used, and the computing power of the workstation may be used to course of the uncooked output to make the occupied/unoccupied determination. The occupancy sensors could include onboard electronics which might be solely sufficient to adjust the sensitivity and time-out delay based on local inputs on the occupancy sensor, or the electronics may be ready to adjust the occupancy sensor in response to adjustable parameters that are input by a workstation person through a pop-up or management panel and transmitted through a USB or other wired or wireless connection. Energy strips having a number of switched and unswitched power receptacles may present an excellent platform to switch energy to external workstation peripherals corresponding to process lighting, printers, house heaters, and so on., in response to an occupancy sensor coupled to the workstation. However, different power switching platforms could also be used including single-receptacle plug-in modules that plug straight into a wall outlet without a energy cord and talk with the workstation by means of a wired or wireless connection equivalent to a Bluetooth wireless interface. Different examples embrace constructing wiring gadgets reminiscent of wall shops that have switched receptacles and communicate with the workstation through a wired or wireless connection. One kind of energy strip could embody a USB connection to the workstation with a mixture of switched and unswitched receptacles as proven in FIGS. 9 and 11. Another sort of receptacle might not have a connection to the workstation, but instead may be connected on to the occupancy sensor by way of a wired or wireless connection. Such an embodiment could have inbuilt sensitivity and time-out delay functionality and may embrace person inputs to regulate these parameters. In embodiments in which a workstation could also be positioned in a standby or hibernate mode when the space associated with the workstation is unoccupied, the facility for the USB or other connection to the occupancy sensor could also be turned off. Subsequently, the workstation working system might should be configured to wake when it receives a signal on the USB or different connection. The inventive rules of this patent disclosure have been described above with reference to some particular instance embodiments, however these embodiments will be modified in arrangement and detail with out departing from the inventive concepts. For example, some of the embodiments described above are illustrated in the context of lighting management systems, but the inventive principles could also be applied to HVAC systems, security methods, etc. As an additional instance, much of the functionality in the embodiments described above is described in the context of a software program implementation, but any of the performance could even be applied with analog and/or digital hardware, software program, firmware, or any suitable combination thereof. Such modifications and modifications are thought of to fall inside the scope of the next claims.
