Abstract:
A fastening device may include a hollow void. The hollow void may contain an inner coil proximate to a first end of the device, a sensing portion to sense a characteristic associated with the fastening device during a sensing time window, and a controller. The controller may rectify an alternating current from the inner coil during a charging time window, store energy associated with the rectified alternating current, and use the stored energy to charge the sensing portion during the sensing time window. An outer coil outside the fastening device may be located proximate to a second end of the device as compared to the inner coil. An interface portion outside the fastening device may provide an alternating current to the outer coil during the charging time window, detect the sensed characteristic via the outer coil during the sensing time window, and transmit an indication of the detected characteristic value.
Abstract:
A full-duplex RF communication system and corresponding methods use digital adaptive filters for interference cancellation. As provided, the techniques allow full-duplex radio frequency communication without frequency-, time-, or code-division multiplexing and without the use of hardware RF cancellers, in real-time. Such techniques may be useful for wireless communication, such a cellular communication, radio communication, broadcasting, short-range point-to-point communication, wireless sensor networks, and wireless computer networks.
Abstract:
A smart street lighting system and method employs a plurality of street lights having a luminaire, a luminaire associate and a support pole. A communications module is contained within the luminaire associates and a power line is contained within the support poles. The power line is coupled to the communications module, the luminaire associate and the luminaire, and a steerable millimeter wave radar operatively coupled to the communications module. The communications module operates in a radio frequency network in a frequency range of 57-64 GHz. The steerable millimeter wave radar provides a signal reflected from a target that may be received by one of the luminaire associates within the system. A powerline communications system interfaces with the radio frequency network to provide communications between the communications modules in the street lights and the PLC system.
Abstract:
A communication system includes an omnidirectional antenna to receive a wideband primary signal, a nulling antenna to receive a secondary signal and a controller. The nulling antenna is oriented to place a null in a direction of a desired communication signal and the controller subtracts a processed secondary signal from a processed wideband primary signal to produce a jamming cancelled signal.
Abstract:
Some embodiments are directed to an Internet of Things (“IoT”) associate to facilitate implementation of a digital twin of a twinned physical system. The IoT associate may include a communication port to communicate with at least one component, the at least one component comprising a sensor or an actuator associated with the twinned physical system, and a gateway to exchange information via the IoT. A computer processor and local data storage, coupled to the communication port and gateway, may receive a digital twin model from a data warehouse via the IoT. The computer processor may be programmed to, for at least a selected portion of the twinned physical system, execute the digital twin model in connection with the at least one component and operation of the twinned physical system.
Abstract:
An engine communication system for aircraft engines having a nacelle with two cowlings extending annularly about the aircraft engine and defining a radially outward surface thereof, and at least one sensor positioned radially inward from the nacelle. The system includes a cowling gap positioned between the two cowlings when coupled together, and an engine control device communicatively coupled to the sensor and configured to at least one of receive engine data from the sensor and receive instruction data from a transmitter device positioned radially outward from the cowling gap. The system also includes a linearly polarized antenna communicatively coupled to the engine control device and positioned radially inward from the cowling gap and extending radially outward toward the cowling gap. The antenna is configured to at least one of receive and transmit the engine data and the instruction data through the cowling gap.
