  • Patent number: 10840962
    Abstract: An electronic device and a grip recognition method for reducing the SAR of the electronic device are provided. The electronic device of the present disclosure includes an antenna, a coupler, a processor electrically coupled to the antenna and the coupler, and a memory electrically coupled to the processor. The memory stores instructions that, when executed by the processor, cause the processor to detect a change of a transmit power value using the coupler during transmission of a radio signal through the antenna. The instructions further cause the processor to determine whether the electronic device is being gripped based on the change of the transmit power value.

  • Patent number: 10834676
    Abstract: A wireless device and a method therein for performing one or more operations based on available energy. The wireless device is configured to operate in a wireless communications network. Based on an amount of energy available for operation and based on control information, the wireless device determines an allocation of the amount of available energy between at least a first energy part and a second energy part. The first energy part is to be used in a sensing operation using a sensing operation configuration and the second energy part is to be used in a communicating operation using a communicating operation configuration. The wireless device performs based on the determined allocation, one or more operations out of: the sensing operation using the first energy part and the sensing operation configuration, and the communicating operation using the second energy part and the communicating operation configuration.

  • Patent number: 10812664
    Abstract: A power transmission system includes a voltage measurement device located on a tower or rooftop for measuring a voltage (VRRH) at a top end of a DC cable connected to a remote radio head (RRH). A voltage control system receives an input voltage (VIN) from a DC power supply and generates an output voltage (VOUT) at a base end of the DC cable. The voltage control system calculates a voltage drop on the DC cable based on the VRRH measurement and then adds different voltage steps to VIN so VOUT compensates for the voltage drop. Calculating the voltage drop allows the PTS to more efficiently supply power to RRHs without having to increase the size of DC power cables.

  • Patent number: 10786902
    Abstract: Described herein is a method of deploying sensors by a robot in a geographical region. The robot receives a first instruction including information corresponding to the geographical region and a second instruction indicating one of a first manner and a second manner of deploying sensors. The robot computes a path to traverse the region in a plurality of steps, each step of the plurality of steps having a predetermined magnitude. The robot traverses until a stopping condition is satisfied. The robot deploys sensors at each traversed step size and further receives from each deployed sensor, information indicating absence of sensors in a neighboring area of the deployed sensor. Additionally, the robot repeats the traversing and deploying of sensors in the neighboring area to provide full coverage.
