Abstract:
Systems and related methods providing for determining activities of individuals are discussed herein. Circuitry may be configured to wirelessly receive tag signals from a plurality of RF location tags. Two or more of the RF location tags may be positioned on an individual, such as at positions that may at least partially define a human frame. The circuitry may be configured to correlate the two or more RF location tags with the individual. Location data for each of the two or more RF location tags may be determined based on the received tag signals. An activity of the individual may be determined based on the location data. In some embodiments, one or more activities involving multiple individuals may be determined based on RF location tags and sensors positioned on each of the multiple individuals. Furthermore, sensor data from the sensors may be communicated over the UWB channel.
Abstract:
A method for predicting a criteria of interest based upon tag location data, derived tag location data, statistical data or the like corresponding to an object. The method may include receiving an input that defines one or more objects and one or more criteria of interest. Further, the method may include accessing tag location data, derived tag location data or the like for the object. The method may also include generating a prediction for a criteria of interest for at least one of the one or more criteria of interest for at least one of the one or more objects, wherein the a prediction for a criteria of interest is generated based on at least one of tag location data, derived tag location data or the like for the one or more objects related to the one or more criteria of interest. An associated apparatus, computer program product and system are also provided.
Abstract:
A system and its associated methodology for distributed positioning and collaborative behavioral determination among a group of objects, interactive tags associated with each of a plurality of objects provide to each object relative positional data and state information regarding the other nearby objects. Using this information, each object develops a spatial awareness of its environment, including the position and action of nearby objects so as to, when necessary, modify its behavior to more effectively achieve an objective.
Abstract:
An apparatus, system, method and computer program product for secure ranging between at least two devices in radio communications with each other. In particular, an apparatus, system, method and computer program product for secure ranging between at least two devices communicating via ultra wideband (UWB) protocols. Either ternary-IR or time-hope-IR sequences are used for ranging and security. A first device transmits a range packet. A second device responds to the range packet after a delay time known only to the first and second devices. The delay time can be selected randomly by either to the first device or the second device and made known to the other device in an encrypted notification packet.
Abstract:
A method for synchronizing on a pulsed waveform sequence including pulsed waveforms. An impulse radio receiver is provided including a radio frequency (RF) front end (30) connected to a demodulator (31), and the demodulator is connected to a processing unit (32). Power is provided to at least a portion of an RF component such as the RF front end and/or the demodulator, during time windows sufficient for testing an hypothesis regarding timing of the pulsed waveforms. The powering is controlled by the processing unit. Preferably, testing the hypothesis includes accumulating a signal of the pulsed waveforms, correlating with the pulsed waveforms, or accumulating the correlation result of the pulsed waveforms. Preferably, others functions of the receiver are powered or enabled subsequent to the testing. Preferably, the impulse radio receiver is an ultra-wide band receiver.

A system to capture data regarding conditions in a sealed metal shipping container having: a sensor unit mountable inside the container and adapted to sense a condition inside of the container; an impulse radio transmitter receiving data from the sensor regarding the condition and transmitting an impulse radio wireless signal inside of the container; an impulse radio receiver external to the container and proximate the container, wherein the receiver is adapted to receive the impulse radio wireless signal propagating through the sealed metal shipping container, and a data device in communication with the receiver to capture the data from the sensor unit regarding the condition inside of the container.
Abstract:
The present invention relates to a method and system (10) for distance determination of RF tags (4) and its applications, based on measuring the round trip delay, avoiding deterministic collisions between a plurality of wide band response signals transmitted by the tags (4) by adding a pseudo-random time delay to the wide band response signal, and iteratively reducing the collision probability between plurality of wide band response signals.
