Abstract: Aspects and features of this disclosure include operating an RFID reader to identify targeted tags and background tags from among a population of RFID tags. The background tags are then monitored by reading the background tags at a background rate and the targeted tags are tracked by reading the targeted tags at an enhanced rate. The enhanced rate is significantly greater than the background rate. The tags from a large population can be segregated into the two subpopulations based on read measurements stored in a tag database. A tag may become “targeted” by moving towards or appearing near a portal of interest. Tag detection, and therefore an alarm message or some other desired result, can be provided quickly due to the higher, enhanced read rate being applied to the targeted tags.

Abstract: A system and method can determine the position of a tag antenna relative to a plurality of spaced apart fixed base antennae using ultrawideband signals by using an angle of arrival determined by time of arrival of an ultrawideband signal from the tag antenna to disambiguate a differential phase angle of arrival measured from the differential phase of the ultrawideband signal between the two base antennae. Accordingly, a non-ambiguous phase angle of arrival of the ultrawideband signal from the tag antenna may be used with a range of the tag antenna measured by one or more methods including by 2-way time of flight, to determine the position of the tag antenna relative to the base antennae. The system and method can also use a plurality of pairs of antennae to determine a 3D position of the tag antenna.

Abstract: Aspects and features of this disclosure include a radio frequency identification (RFID) antenna multiplexer. An RFID reader and an RFID system using the RFID antenna multiplexer are also disclosed. The multiplexer includes multiple output ports. Each of at least some of the output ports is connectable to an antenna or another device. In some aspects, a logic circuit in the multiplexer is configured to cause a radio frequency (RF) switch to select an output port from the multiple output ports to connect to the input port based upon a reduction in RF power at the input port. In some aspects, the multiplexer includes an energy harvester connected to the input port to harvest signal energy from the RFID reader and a storage device connected to the energy harvester to store the signal energy and supply power to the multiplexer using the signal energy.

Abstract: A system and method for controlling a seat device. A control unit broadcasts an identifier associated with a seat assigned to a passenger, and establishes a personal wireless area network connection with a personal electronic device (PED) associated with the passenger. The control unit monitors strength of a signal received from the PED over the wireless personal area network, and sets a flag based on the strength of the signal. The control unit receives, over the wireless personal area network, a command from the PED to control the seat device, and determines state of the flag in response to the command. The control unit transmits a signal to take an action invoked by the command in response to the flag being in a first state, and refrains from transmitting the signal to take the action invoked by the command in response to the flag being in a second state.

In one illustrative embodiment, a demand control ventilation system includes a damper for controlling a flow of outside air into a building.

This calibration can, in some instances, help increase the efficiency and/or utility of the demand control ventilation system.
