Abstract: A liquid droplet discharging apparatus is movable and includes a plurality of nozzles to discharge a liquid droplet onto a medium according to a first image data section and a second image data section of image data. A moving amount sensor detects a moving amount of the liquid droplet discharging apparatus. A switcher switches from the first image data section to the second image data section based on the detected moving amount.

Abstract: A system in accordance with the present disclosure comprises a sensor and an information processing apparatus that includes processing circuitry. The sensor is installed on a surface so that a detection direction of the sensor is at a non-zero angle from a line normal to the surface. The processing circuitry is configured to communicate with the sensor, calculate a position of a detection area, in which the sensor detects an object in a predetermined space, according to the non-zero angle and a location of the sensor on the surface, and create correspondence information that associates an area of the predetermined space with the detection area.

Abstract: An information processing apparatus includes circuitry that acquires a measured temperature of a target area from a measuring device, detects whether the measured temperature changes during a predetermined time period, determines whether a human exists in the target area based on the measured temperature and the detection result indicating whether the measured temperature changes during the predetermined time period, measures a duration of time in which the determination result indicating that the human exists in the target area and the detection result indicating that there is no temperature change are kept generated, and determines that there is no human in the target area even when the determination result indicates that the human exists, if the measured duration of time reaches a certain time period, the certain time period being modifiable based on history information indicating a previously generated determination result indicating whether the human exits in the target area.
