Abstract: A wireless-power transmission system (WPTS) includes sensors, antennas, a power amplifier (PA), and integrated circuits (ICs). The antennas, upon receiving an amplified signal for the PA, are configured to radiate energy within a transmission field (TF) of the WPTS. The ICs are configured to receive sensor data indicating presence of an object within a keep-out zone (KOZ). The ICs are configured to classify using the sensor data the object as a sensitive object. While detecting presence of the sensitive object, the ICs are configured to forgo providing an instruction to the PA to amplify the signal. In accordance with a determination that the sensitive object is no longer detected the ICs are configured to determine whether an electronic device is within the TF and in accordance with a determination that the electronic device is within the TF the ICs are configured to instruct the PA to amplify the signal.

Abstract: A method includes: receiving, by a transmitter, an advertisement signal from a wearable device, the advertisement signal containing: (i) binary data indicating a direction of the wearable device, and (ii) one or more identifiers associated with the wearable device. The method also includes: in response to authenticating the wearable device based on the identifiers: establishing, by the transmitter, a communication channel with the wearable device; and transmitting, by the transmitter, one or more power transmission waves in the direction of the wearable device. The method further includes: receiving, by the transmitter, from the wearable device at least one control signal that indicates an adjustment for transmitting the one or more power transmission waves by the antennas of the transmitter. The method additionally includes: transmitting, by the transmitter, the one or more power transmission waves based on the adjustment and ceasing, by the transmitter, the communication channel with the wearable device.

Abstract: A system includes a linked-list generator module that generates a linked list of tones based on tones and bit loads of the respective tones in a digital subscriber line (DSL) communication system, a trellis encoder module that encodes data bits associated with respective ones of the tones, and a bit application module that communicates the data bits to the trellis encoder module based on the linked list.

Abstract: A system (400) and apparatus (200, 300) for, and method (100) of, interfacing a demodulator and a forward error correction decoder enables a forward error correction decoder to be used in conjunction with an otherwise incompatible demodulator. Data received from the demodulator having a first encoding and formatted as M bits per baud at a first baud rate is encoded into data having a second encoding. The data having the second encoding is output to the forward error correction decoder as N bits per baud at a second baud rate as required by the forward error correction decoder.
