A beacon anchor may include a signal generator configured to generate an ultra-wide band signal inclusive of a unique identifier associated with the beacon anchor, where the UWB signal is a pulse sequence. A transceiver may be in communications with the signal generator. Responsive to receiving the UWB signal from the signal generator, the UWB signal may be broadcast. A processing unit may be in communication with the transceiver, and, responsive to receiving a unicast communications session request from a portable device, be configured to establish a unicast communications session with the portable device to enable a distance between the portable device and beacon anchor to be determined. Through use of UWB signals, relative position (e.g., in front of or behind the beacon anchor) may be determined, thereby enabling different actions to be taken in response to determining the relative position.

High accuracy indoor locating system

A data reading system, and associated methods of operation, for locating and tracking a position of tagged items on a conveyor system. The system includes a data reader and a conveyor system operable to transport the tagged items through a read region of the data reader. A processor, in operative communication with the data reader, obtains data from an item tag being passed through the read region at a first time, at a second time, at a subsequent third time, and so forth. Based on the readings, the processor estimates an initial position of each item tag and determines an order at which each item reaches a reference position on the conveyor system.

Method and system for determining the position and movement of items using radio frequency data

In a UWB real time locating system, UWB readers () are synchronized by adjusting a clock of a UWB slave reader () until the UWB reader () receives each UWB pulse () of a sequence of UWB pulses () having a predetermined pulse period (Tp) and encoding a master UWB reader unique identifier at an expected time slot () within each predetermined pulse period (Tp), the expected time slot () being related to the distance between the UWB tag reader () and a master UWB reader ().

Synchronization of a real-time UWB locating system

A device and method to compensate for distortions of amplitude that afflict systems for communicating through capacitive coupling. A circuit includes a first transmitter stage, a first receiver stage, and a first coupling capacitor, coupled between the first transmitter stage and the first receiver stage. The first receiver stage includes a calibration amplifier of a variable-gain type coupled between the first coupling capacitor and an output of the electronic circuit. The electronic circuit includes a reference channel formed by: a transmission calibration stage; a reception calibration stage; and a reference capacitor coupled between the transmission calibration stage and the reception calibration stage. The reception calibration stage includes: a reception amplifier of a variable-gain type, having an input coupled to the reference capacitor, and a gain controller, having an input coupled to an output of the reception amplifier and an output coupled to control terminals of the reception and calibration amplifiers.
