    Abstract: A controller switches between modes each having a different connection state of a DC power supply and the capacitor with respect to first and second output points by controlling switches. A generation unit generates a reference wave including at least one carrier wave. The modes are classified into a sustaining mode in which no current is caused to flow to the capacitor, a charging mode in which a current is caused to flow to the capacitor, and a discharging mode in which a current in a direction opposite to that in the charging mode is caused to flow to the capacitor. The controller switches between the sustaining mode and a charging or discharging mode according to the comparison result between a signal wave and the reference wave.

    Abstract: Disclosed herein is a receiver including a receiver circuit, a control circuit, and a wireless communications circuit. The control circuit retrieves identification information and content information from a plurality of transmitters based on an output of the receiver circuit. The control circuit retrieves, when having failed to retrieve content information from the plurality of transmitters, identification information from at least two of the plurality of transmitters, identifies one of the at least two of the plurality of transmitters as a target transmitter in association with the retrieved identification information, and also identifies another one the at least two of the plurality of transmitters as a non-target transmitter in association with the retrieved identification information. The wireless communications circuit transmits the control signal to allow the target transmitter to transmit the second optical signal and cause the non-target transmitter not to transmit the second optical signal.

    Abstract: A visible light communication apparatus includes: an on/off switch connected in series to a load circuit including a light emitting diode; an impedance circuit connected in series to the on/off switch; a feedback circuit that feeds back an error between a voltage drop across the impedance circuit and a reference voltage potential to a voltage source as a feedback signal; a drive circuit that turns on and off the on/off switch in accordance with a communication signal which is a binary signal; an isolation circuit that transmits power while being electrically isolated; and an auxiliary power supply circuit that is connected between two output terminals of the voltage source, generates an auxiliary supply voltage, and supplies power based on the auxiliary supply voltage generated to the on/off switch and the drive circuit via the isolation circuit.

    Abstract: A human body surface temperature calculation system includes: an infrared sensor; an obtainer that obtains temperature distribution data indicating a temperature distribution in a target space which is obtained by the infrared sensor; a thermal image generator that generates a thermal image of the target space based on the temperature distribution data obtained by the obtainer; an extractor that extracts, using a machine learning model, a human region indicating a person captured in the thermal image; and a calculator that extracts a temperature value group corresponding to the human region from the temperature distribution data and calculates a body surface temperature of the person based on the temperature value group extracted.
