  • Patent number: 11963166
    Abstract: The invention relates to a user equipment for being scheduled with uplink radio resources. The user equipment receives from a radio base station a first-stage uplink resource scheduling message, indicating uplink radio resources usable by the UE to perform an uplink transmission via an unlicensed cell. The receiver further receives a second-stage uplink resource scheduling message, which is related to the first-stage uplink resource scheduling message. Upon reception of the second-stage uplink resource scheduling message, a processor of the UE determines that an uplink transmission is scheduled in case the first-stage uplink resource scheduling message is valid. The first-stage uplink resource scheduling message is determined valid based on a determination as to whether an uplink transmission has been triggered by another second-stage uplink resource scheduling message within a predetermined time period prior to reception of the second-stage uplink resource scheduling message.

  • Patent number: 11960010
    Abstract: A positioning terminal is provided and identifies, as appropriate, a satellite to be excluded, thereby improving positioning accuracy. A processor acquires a signal-to-noise ratio (SNR) and an angle of elevation for each satellite. The processor next identifies a satellite for which the SNR is less than a shielding SNR mask as a multipath satellite and selects the satellite to be excluded. The processor next generates positioning terminal positioning data using a positioning signal from satellites other than the satellite to be excluded. The processor next uses reference station positioning data and positioning terminal positioning data of the selected satellite to execute an RTK calculation.

  • Patent number: 11958173
    Abstract: An impact tool includes a motor, a control unit, an output shaft, a transmission mechanism, and an impact detection unit. The transmission mechanism includes an impact mechanism. The impact mechanism applies impacting force to the output shaft while performing an impact operation. The impact detection unit determines, based on at least one of an excitation current (current measured value) to be supplied to the motor or a torque current (current measured value) to be supplied to the motor, whether or not the impact operation is being performed. The control unit places a limit on an increase in the number of revolutions of the motor before the impact detection unit detects the impact operation and removes the limit on the increase in the number of revolutions of the motor when the impact detection unit detects the impact operation.

  • Patent number: 11962183
    Abstract: A backup power system according to the present disclosure includes a battery, a charging circuit, power storage, a first load, a second load, and a controller that controls the charging circuit. The controller causes an input current at the charging circuit to increase at a first rate of change in response to a start signal. When the controller detects an increase in a charging voltage at the power storage up to a first voltage at which driving of the first load is possible, the controller controls the charging circuit to cause the input current at the charging circuit to increase at a second rate of change lower than the first rate of change. The charging circuit is controlled by the controller to cause the input current to increase at the second rate of change, and the charging voltage at the power storage increases up to a second voltage at which driving of both the first load and the second load is possible.
