Abstract: Technologies for monitoring a characteristic of a monitored system include determining a measured value of the primary characteristic of the monitored system sensed by a primary sensor and a measured value of the secondary characteristic of the monitored system sensed by a secondary sensor, and predicating a predicted value of the primary characteristic based on the measured value of the secondary characteristic. The measured and predicted values of the primary characteristic are used to determine whether the primary sensor is properly functioning.

Abstract: Systems and methods for latch-up detection and mitigation. One aspect includes a method implemented in a system divided into a plurality of power blocks, where each power block is powered by a corresponding power rail and includes a voltage droop monitoring circuitry. The method comprises receiving frequency information from the plurality of voltage droop monitoring circuitries; normalizing the received frequency information from each of the plurality of voltage droop monitoring circuitries; creating a matrix of cross-correlation values based on the normalized frequency information between each pair of the plurality of power blocks; determining deviations in the cross-correlation values indicating an occurrence of voltage droop; determining an abnormal variation based on the determined deviations to identify a first power block, out of the plurality of power blocks, experiencing a latch-up event; and resetting power to the first power block without interrupting power to rest of the plurality of power blocks.

Abstract: Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmitter coil configured to generate a magnetic field to wirelessly power a device within an active wireless charging area. The power transmitting unit also includes a power generating circuitry to deliver current to the transmitter coil to generate the magnetic field. The power transmitting unit also includes a shield disposed around the transmitter coil to reduce the strength of the magnetic field outside of the active wireless charging area.

Abstract: Embodiments of the present disclosure provide techniques and configurations for controlled power level adjustment of a wireless charging apparatus. In one instance, the apparatus may comprise a charging module to radiate an electromagnetic field to wirelessly charge an electronic device in proximity to the wireless charging apparatus; and a control module communicatively coupled with the charging module to adjust a power level of the electromagnetic field, radiated by the charging module, in response to a determination of an environmental condition in relation to the wireless charging apparatus. The control module may be configured to receive information indicative of the environmental condition from multiple sources distributed between the apparatus and the electronic device, and make the determination based at least in part on the received information. The environmental condition may comprise a presence of human tissue in proximity to the wireless charging apparatus. Other embodiments may be described and/or claimed.

Abstract: A proximity sensing headphone may include a gyroscopic sensor to determine the motion of the headphone structure and a proximity sensor to determine the movement of an external object through a three-dimensional ambient environment. A proximity sensing headphone control circuit determines the relative motion or movement between the headphone structure in the three-dimensional ambient environment and the external object in the three-dimensional ambient environment to determine at least a distance between the headphone structure and the external object and a velocity of the external object through the three-dimensional ambient environment about the headphone structure. The control circuit may provide an alert output if the determined distance between the headphone structure and the external object is less than a defined distance threshold or the velocity of the external object through the three-dimensional ambient environment about the headphone structure exceeds a defined velocity threshold.
