Abstract: A method of determining a power transmission device to be set as a master device such that wasteful communication is not caused. In a wireless power feeding system, a power transmission device that transmits electric power to a power reception device forms a group with other power transmission devices. The power transmission device performs communication with the power reception device or the other power transmission devices using a wireless transmission section and a wireless reception section, and exchanges information with the other power transmission devices. The power transmission device receives a setting for determining a power transmission device to be set as a master device out of the self device and the other power transmission devices, with which information has been exchanged. If the received setting is for setting the self device as the master device, the self device is set as the master device.

Abstract: A human presence sensor unit in which an ultrasonic wave sensor is mounted is fixed to a frame sheet metal of an image forming apparatus with a pedestal interposed therebetween. The pedestal is made of a synthetic resin material, and the frame sheet metal is made of a metal material. As the pedestal and the frame sheet metal are made of different materials, a difference in the acoustic impedance is produced between the pedestal and the frame sheet metal.

Abstract: An information processing apparatus including: a sound wave sensor that outputs a sound wave and receives a reflected wave of the output sound wave; a control unit configured to measure an amplitude of a sound wave, at predetermined time intervals, which is received by the sound wave sensor after the sound wave sensor outputs a sound wave; and a power control unit configured to shift the information processing apparatus from a first power state into a second power state where power consumption is larger than that in the first power state, on a basis that the amplitude of the sound wave measured by the control unit is larger than or equal to a threshold value, wherein in a case where a number of times amplitude of a sound wave measured by the control unit is larger than or equal to the threshold value during a predetermined period of time is larger than or equal to a predetermined number of times, the control unit maintains the power state of the information processing apparatus in the first power state.

Abstract: There is provided a printed circuit board, on which a piezoelectric element for generating vibration is mounted, is fixed to a pedestal. Two slits are formed on a straight line that connects first position where the piezoelectric element is mounted on the printed circuit board and a second position where the printed circuit board is in contact with the pedestal.

Abstract: An image forming apparatus measures the distance between the image forming apparatus and an object located in the periphery of the image forming apparatus each predetermined amount of time. Then, whether or not the object is a human is detected on the basis of the measured distance and a moving amount of the object each predetermined amount of time. Furthermore, the image forming apparatus controls the power supply state of the image forming apparatus in accordance with the result of the human detection.
