  • Patent number: 10136399
    Abstract: A capacitive proximity detector for use in a connected portable device such as a telephone, laptop or tablet, in which the capacity seen by the sensor electrode is compared with four thresholds: a proximity threshold, set lower than the other, to generate a general proximity flag, and a body detection threshold set higher than the other arranged to generate a body detection flag that indicates that the object in proximity is a part of a human body. Two object detection thresholds in the region between the proximity threshold and the body threshold define a region in which the detector can decide whether the object in proximity is an inanimate object, based on the time variation of the capacity.

  • Patent number: 10117207
    Abstract: Over-the-air (OTA) phase synchronization for reciprocity-based coordinated multipoint (CoMP) joint transmission is disclosed. Phase synchronization reference signals (PSRS) are transmitted within a CoMP operation that can be used to determine the phase drifts of the transmit and receive chains of the base stations. These phase drifts can then be used to obtain a relative phase drift between the uplink and downlink channels. When estimating the uplink channel from the sounding reference signals (SRS), the relative phase drift may be applied to estimate the downlink channel as well. The OTA phase synchronization may be performed with a user equipment (UE)-assisted or inter-base station procedures.

  • Patent number: 10110271
    Abstract: Described herein are circuits and methods for improving switch performance when overdriving the gate by adding a delay on a PMOS gate voltage such that it can turn on the PMOS during switch state transition to allow charge/discharge of the switch body voltage faster and it can turn off once the process is complete. For example, back-to-back diodes can be used to separate the PMOS gate and drain. This can reduce leakage current and can reduce or eliminate the potential for breakdown of the switch.
