摘要： A system includes one or more assets loaded onto or removed from a vehicle, where each asset is coupled to a wireless tag and each wireless tag wirelessly transmits beacon signals at predetermined intervals. The system includes a gateway disposed within the vehicle. The gateway includes one or more sensors that gather motion and/or vibration information. The gateway scans an area of the vehicle at a duty cycle to identify beacon signals transmitted by the wireless tags and receives the beacon signals from the wireless tags. The gateway dynamically adjusts the duty cycle based in part on the gathered motion and/or vibration information.

摘要： During hand-held operation, configuration of an NFC/RFID Reader/Writer peripheral device in a predefined mode named “Mobile Mode with Auto-Collection”, enables recognition of a long duration (e.g. 5 second) trigger press (AKA a “Long Press”) as an enabling event prompting a change of scan behavior between single-shot scan operation and continuous scan operation. In other defined Modes of the peripheral device, other predetermined enabling events, such as the presence or absence of a predetermined external power source, prompt the change between single-shot and continuous scan operations. The Long Press and the other intuitive features enable the general user to be able to switch between various modes and to do so without requiring acquisition or use of an additional dedicated scanner with its requisite expense or inconvenience, and without requiring advanced knowledge, special access, or special resources.

摘要： A method of communicating with one or more RFID sensor tags within a predetermined area. The method comprises: providing an RFID sensor tag interrogation apparatus comprising an RF transceiver configured to enable control of a transmitted RF power level; setting the transmitted RF power level to provide an RF signal detectable by RFID sensor tags located within a corresponding region of the predetermined area; transmitting, by the RFID sensor tag interrogation apparatus, an RFID sensor tag interrogation signal; and receiving, by the RFID sensor tag interrogation apparatus, one or more responses transmitted by the RFID sensor tags located within the predetermined area. In some embodiments the transmitted RF power level is adjusted to increase or decrease the size of the corresponding region of the predetermined area, based upon responses received from RFID sensor tags located within the region.

摘要： A method and device of power management for a networked radio frequency identification (“RFID”) system are disclosed. The described power management methods reduce the power consumption of battery-operated RFID readers and RFID tags. These power conservation methods increase the RFID system's hours of operation and decrease the cost by allowing the RFID readers and tags to function for a longer period of time before requiring charging or replacement of their batteries.

摘要： An RFID sensor tag includes a processor, a power source, an RF transceiver, one or more sensors accessible to the processor via a sensor interface, and at least one memory device. In one example, the tag is configured to operate in a low power-consumption state, a medium power-consumption state in which sensor measurements are performed, and a high power-consumption state used when engaged in RF communications. In another example, power consumption and memory usage are reduced by configuring the tag to record sensor data only upon satisfaction of a predetermined condition. In a further example, the tag is configured to respond to an RF interrogation signal only when the signal includes an instruction in accordance with a predetermined communications protocol. In another example, the tag is configured, upon interrogation, to confirm whether new recorded sensor data is available, to minimise transmission in the event that no new data is available.

摘要： An RFID tag is configured to adjust its current clock frequency to conserve tag power while receiving a reader signal and/or backscattering a signal. The tag may determine whether to adjust its current clock frequency based on one or more timing parameters, which may be determined from a reader command and/or from a signal to be backscattered. The counting rate and/or limit of a tag counter and/or the power supplied to a tag component may also be adjusted. The current tag clock frequency may be adjusted during the signal reception/backscattering process and optionally restored once the process is completed.
