  • Publication number: 20250106610
    Abstract: A U2N relay (110 #2) transmits a first sidelink discovery message containing base-station identification information of a base station (130) when the U2N relay (110 #2) is in communication range with the base station (130). When a U2U relay (110 #3) is in communication range with the U2N relay (110 #2) and not in communication range with the base station (130), the U2U relay (110 #3) receives the first sidelink discovery message and transmits a second sidelink discovery message containing mobile-terminal-device identification information of the U2N relay (110 #2) and base-station identification the information. When a remote UE (110 #1) is in communication range with the U2U relay (110 #3) and no in communication range with the base station (130) and the U2N relay (110 #2), the remote UE (110 #1) receives the second sidelink discovery message and establishes communication path to communicate with the base station (130) via the U2U relay (110 #3) and the U2N relay (110 #2).

  • Patent number: 10585169
    Abstract: A signal generating circuit includes a control voltage setting unit (CVSU) configured to set a control voltage for a chirp signal using voltage-frequency characteristics indicating characteristics of an output frequency versus voltage; a VCO configured to alter the frequency of its output signal by the control voltage; a quadrature demodulator configured to perform quadrature demodulation of the output signal of the VCO to generate an inphase signal and a quadrature signal orthogonal to each other; and a frequency detector configured to detect the frequency of the output signal of the VCO on the basis of the inphase signal and quadrature signal. The CVSU corrects the control voltage by using the voltage-frequency characteristics derived from relationships between the control voltage and the frequency of the output signal of the VCO. The VCO generates the chirp signal based on the control voltage corrected by the CVSU.

  • Publication number: 20200076453
    Abstract: A signal source (44) supplies local signals having different phases to a first mixer (42) and a second mixer (43). The first mixer (42) and the second mixer (43) perform frequency conversion on reception signals using the local signals. A first phase changing unit (51) and a second phase changing unit (52) receive output signals of the first mixer (42) and the second mixer (43) as input signals and generate in-phase and reversed phase signals of these signals. A first adder (53) adds output signals of the first phase changing unit (51) to separate multiple signals. A second adder (54) adds output signals of the second phase changing unit (52) to separate multiple signals.

  • Patent number: 10543869
    Abstract: An electronic control unit diagnoses a short failure of an inverter FETs and diagnoses whether the failure of the FET-short detecting section has occurred. The unit controls a motor through an inverter including a bridge having an upper-stage FETs and a lower-stage FETs via an MCU, having: an FET-short detecting section to detect a short failure of the upper-stage FETs and the lower-stage FETs based on respective connection point voltages of the upper-stage FETs and the lower-stage FETs; and a diagnostic function to detect a failure of the FET-short detecting section. The diagnostic function diagnoses the failure of the FET-short detecting section at start up and turns-OFF the upper-stage FETs and the lower-stage FETs when the failure is detected. The FET-short detecting section diagnoses the short failure of the upper-stage FETs and the lower-stage FETs when the failure of the FET-short detecting section is not detected.

  • Patent number: 10516209
    Abstract: Synthesizers (32, 24) for synthesizing feedback signals output from a plurality of antenna modules (4) are provided. A distortion compensation signal output unit (15) derives, from a difference between a feedback signal synthesized by the synthesizers (32, 24) and a base band signal output from a modulation unit (12), a distortion compensation coefficient that provides, to the base band signal, distortion characteristics opposite to distortion characteristics of a signal radiated from the phased array antenna and outputs a predistortion signal representing the distortion compensation coefficient to a PD unit (13).

  • Patent number: 10471984
    Abstract: An electronic control unit where an external watch dog timer (WDT) can always normally detect an abnormality (a failure) to a micro controller unit (MCU) related to a built-in self-test (BIST) function and which can maintain safety of a system. The control unit includes an external WDT to detect an abnormality of the MCU, a reset circuit to reset the MCU when the external WDT detects the abnormality of the MCU, and an ON/OFF control section to turn a gate of the semiconductor switching device on or off in accordance with the external WDT. The inverter is stopped by turning the gate off via the ON/OFF control section when the external WDT is a disable state. When the abnormality of the MCU is not detected in an enable state, the inverter is driven by turning the gate on via the ON/OFF control section. When the abnormality of the MCU is detected, the inverter is stopped by turning the gate off via the ON/OFF control section and the MCU is reset by the reset circuit.
