A system and method system for synchronizing Radio Frequency Identification (RFID) readers includes a plurality of RFID readers disposed within an environment. Each RFID reader includes an infrared emitter and an infrared detector. A master controller also includes a master infrared emitter and is operable to emit a master infrared flash from the master infrared emitter for synchronizing the plurality of RFID readers. Any of the RFID readers, upon detecting an infrared flash with their associated infrared detector, is operable to synchronize their dwell timing with the detected infrared flash and emit their own infrared flash from their associated infrared emitter, so as to propagate infrared flashes to all the RFID readers within the environment.

Synchronization of radio frequency identification readers using infrared pulse

A programmable controller and software that monitors periods an RF transmitter is active and a output power level during those periods of activity. These two values are multiplied together and accumulated over time to provide a value for the RF emissions for some period. A limit is set for the RF emissions for any period and if the RF emissions exceeds (or is expected to exceed given the current rate) the set limit, the system limits the subsequent emissions to not exceed the set limit. This reduction in emissions rate come at the cost of a small performance reduction.

Setting SAR exposure limit of mobile devices

A system having a mobile device and a wearable mount configured to couple to the mobile device, the coupling making the mobile device wearable at a worn location, wherein a set of functionalities of the mobile device corresponds to the worn location. The wearable mount having a coupler configured to couples to a mount coupling of a mobile device and a fastener that fastens the wearable mount to a location, the location, a set of functionalities of the mobile device being based on the location.

Wearable mobile computing system

A wearable mobile computer communicates with a headset worn by an operator using a communication channel established between the computer and a radio frequency identification ('RFID') tag located in the headset. The headset may be configured for receive only (voice travels only from the computer to the headset) or configured for two-way voice communication. For two-way communication backscatter from the RFID tag is used to carry voice signals.

Voice over RFID

A system and methods for measuring the temperature of an RFID reader module and inserting a delay in the RFID reader's duty cycle to prevent the RFID reader from initiating a thermal shutdown. The system and methods are self-adaptable, therefore incurring the benefit regardless of the design of the RFID reader host and its associated heat sink. The system and methods also provide for archiving the collected data and analyzing the data providing the ability to improve the design of the RFID reader host.

Thermally controlled duty cycle regulation in an RFID module

A system, apparatus, and techniques for interrogating a Radio Frequency Identification (RFID) tag are disclosed. The system includes an RFID reader that includes a pivotable polarized antenna for reading a reader/tag link. The antenna moves at a specific frequency over a specific distance resulting in reader/tag links being moved out of a null region of the reader. Advantageously, by pivoting the antenna, the antenna apparatus minimizes signal fading and improves signal quality from tags.

Polarized RFID antenna with spatial diversity

Methods, systems, and apparatuses for providing power to devices that are part of RFID systems are described. Energy is harvested at portable/mobile devices, stored and conditioned to provide on-going power as needed for various circuits/components. The energy may be generated in a variety of ways, including using a vibratory energy harvesting device, a magnetic energy harvesting device, and an optical energy harvesting devices.
