Abstract: An electronic device comprises: a transmission antenna configured to transmit transmission waves; a reception antenna configured to receive reflected waves resulting from reflection of the transmission waves; and a controller. The controller is configured to detect an object reflecting the transmission waves, based on a transmission signal transmitted as the transmission waves and a reception signal received as the reflected waves. The controller is configured to make a range of detection of the object by the transmission signal and the reception signal, variable.

Abstract: An object tracking device that can track an object accurately and consistently is provided. An object tracking device (20) includes an input interface (21), a processor (23), and an output interface (24). The input interface (21) is configured to acquire sensor data. The processor (23) is configured to detect a detection target from the sensor data and track the detection target using Kalman filters associated with each of the detection target and an observed value. The output interface (24) is configured to output a detection result regarding the detection target. The processor (23) is configured to impose a limit on a range of variation in an index of the Kalman filters that influences tracking of the detection target.

Abstract: An electronic device includes a transmission antenna that transmits a transmission wave, a reception antenna that receives a reflected wave that is the reflected transmission wave, and a control unit that detects an object that reflects the transmission wave, based on a transmission signal transmitted as the transmission wave and a reception signal received as the reflected wave. The electronic device transmits, to an information processing apparatus, sensing information based on the transmission signal and the reception signal at a location of the electronic device along with location information of the electronic device.

Abstract: An electronic apparatus executes communication with an external device. The electronic apparatus includes an encoder that encodes source data to generate transmission data, a communication device that transmits the transmission data generated by the encoder to the external device, a unit that determines the quality with which the source data is to be transmitted, in accordance with the type of the source data, and a unit that controls the encoder to vary an amount of the generated transmission data on the basis of the determined quality.
