  • Patent number: 10680680
    Abstract: This specification discloses methods and systems providing reader-mode performance enhancement for operating a device that communicates via inductive coupling. In reader-mode, Tx (transmitter) power of a reader device is maximized even though for some tags, the communication distance is limited by Rx (receiver) sensitivity. Therefore, power is wasted. Even worse, a too highly boosted Tx power demands a high Rx dynamic range and consequently a low Rx sensitivity. In turn, the communication distance may even be degraded by a too highly boosted Tx power. Therefore, in some embodiments, reader-mode performance enhancement is based on backing off Tx (transmitter) power when not needed (energy distance>communication distance) to save power and/or to relax reader-mode Rx (receiver) sensitivity requirements. In some embodiments, the backing off of Tx (transmitter) is also based on a sensor determining a geometric position/location of a reader device relative to a tag-mode device.

    Abstract: In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase ?[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase ?[i] stored in the memory are calculated as a phase difference ??[i] and a time difference ?t[i]. A phase addition value ?sum[i] obtained by cumulatively adding a plurality of the phase differences ??[i] is calculated so as to correct a phase difference in which the corresponding time difference ?t[i] among the calculated plurality of the phase differences ??[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value ?sum[i].

  • Patent number: 10250336
    Abstract: A laser beacon may be attached to a vehicle, object, or personnel, or be incorporated into an existing vehicle optical emitter via software and/or hardware, that allows the vehicle, non-vehicle object, or associated personnel to be uniquely identified using a small telescope with a high-speed photodetector. The telescope may be an amateur telescope with a high speed-photodetector, which significantly reduces cost over more complex optical telescopes. Beacons may also be attached to objects that become space debris, such as fuel tanks, rocket stages, cubesat dispensers, and the like. The beacon may be suitable for use in space, in the air, on water, or on land.

  • Patent number: 10229078
    Abstract: Multiple master modules are connected to a bus, each having bus communication logic for initiating a transaction over the bus. The bus communication logic is able to detect when the bus is busy (or apparently busy), and in response will wait before initiating a transaction of its own. Further, a distributed reset sub-system is provided, comprising an instance of a reset mechanism at each of a plurality of the master modules. Each reset mechanism recognizes a timeout condition indicative of the detected busy state being due to error, and in response performs a staged reset. This reset process first attempts a local reset which resets the respective bus communication logic of its respective master module. If the local reset fails to clear the error, the staged reset process then attempts one or more further resets to reset bus communication logic of one or more other modules connected to the bus.

  • Patent number: 10192373
    Abstract: In a tag identification system, active tags are configured to emulate at least one passive tag so that existing passive identifications systems, such as passive radio-frequency (RFID) systems or near field communication (NFC) systems, can be retrofitted to operate with the active tag without having to make expensive hardware updates to the readers within the system. The active tag permits continuous monitoring of its movement or status, as may be desired, regardless of its proximity relative to the readers thereby allowing a system to capture more data regarding the tag's location and use. In addition, the active tag may be compatible with different passive identification systems thereby permitting it to operate with disparate passive identification systems and obviating the need of the user to carry multiple passive tags.

  • Patent number: 10083329
    Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

    Abstract: A system for alerting a user of a device departing a vehicle includes a software application configured to be executed on a memory of the device. The software application performs an initial query phase to periodically query the status of a data connection between the device and the vehicle. Upon confirmation that a data connection has been established, the software application engages an armed state and periodically queries for a failure of the data connection between the device and the vehicle. Upon detecting a failure of the data connection the software application engages an alert state operative to alert a user upon failure of said data connection between the device and the vehicle.

  • Patent number: 10013587
    Abstract: Synthesized-beam RFID readers may be used to locate RFID tags. In one embodiment, a tag's response rates on different beams can be used, along with the target locations of those beams, to estimate the tag's location. The estimated tag location is within a region where beams with nonzero tag response rates overlap, and the distances of the estimated tag location from any two different beam target locations may correspond to a ratio of tag response rates on the two different beams. In another embodiment, a tag's response rates on different beam pairs configured to cooperatively power RFID tags can be used, along with the target locations of those beam pairs, to estimate the tag's location.
