Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: Mapping apparatus includes a transmitter, which emits a beam comprising pulses of light, and a scanner, which is configured to scan the beam, within a predefined scan range, over a scene. A receiver receives the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to control the scanner so as to cause the beam to scan over a selected window within the scan range and to process the output of the receiver so as to generate a 3D map of a part of the scene that is within the selected window.

Abstract: In order to precisely know the light power of a received signal in a wide light input power range, a light reception device comprises: a reception unit that receives a coherent-modulated signal light and outputs a first electric signal to which the signal light has been converted; an amplification unit that amplifies the first electric signal and outputs the amplified electric signal as a second electric signal; and a control unit that determines the light power of the signal light on the basis of a relationship between the light power of the signal light in the reception unit and at least one of the gain of the amplification unit and the amplitude of the second electric signal.

Abstract: A sensor circuit includes a transistor comprising an oxide semiconductor; a first circuit which supplies one of a first potential and a second potential; a first switch; a second switch; and a second circuit to which a current flowing between a source and a drain of the transistor is applied via the second switch when the first potential is applied to a gate of the transistor. The first potential is lower than a potential of the source or a potential of the drain of the transistor, and the second potential is higher than the potential of the source or the potential of the drain of the transistor. The first switch electrically connects the source and the drain of the transistor when the second potential is applied to the gate of the transistor, and electrically isolates them when the first potential is applied to the gate of the transistor.

Abstract: An optical receiver includes a light reception element for receiving an optical signal, a bias voltage supply/monitoring circuit for supplying a bias voltage to the light reception element and generating a monitoring voltage indicating magnitude of an output current of the light reception element, and a constant current source. The bias voltage supply/monitoring circuit is supplied with a remaining current obtained by subtracting the output current of the light reception element from an output current of the constant current source. The bias voltage supply/monitoring circuit converts the remaining current to the monitoring voltage.
