Abstract: A USB power distribution unit according to an embodiment of the present invention has a function of distributing power supplied from a battery to a smartphone connected to a preferred port, and to a mobile battery connected to a non-preferred port. The USB power distribution unit includes a no-idling detection portion, an engine restart detection portion, a PD negotiation portion, and a step-up/down portion, and causes the PD negotiation portion to determine the amount of power supply to the mobile battery when a no-idling state is detected.

Abstract: An input device includes a touch panel having a plurality of transparent electrodes disposed side by side, a hover signal generation unit for generating a hover signal used to detect a height of an indicator located above a surface of the touch panel to input the hover signal to the plurality of electrodes, an XY position detection unit for detecting an X position and a Y position of the indicator based on a signal component that appears on each of the electrodes, and a height detection unit for detecting a height of the indicator based on a signal component that appears on each of the electrodes. The height detection unit performs a correction to the height of the indicator when the XY position of the indicator is within a peripheral portion of the touch panel.

Abstract: In a charging device, a terminal is configured to connect a rechargeable battery. A first power feeding unit is configured to charge the rechargeable battery connected to the terminal. A controller is configured to control the first power feeding unit. A second power feeding unit is configured to feed electrical power to the controller and a monitoring unit. The monitoring unit includes a monitoring portion and a switching element. The monitoring portion is configured to monitor at least one of the rechargeable battery, the first power feeding unit, and the controller. The switching element is configured to interrupt the second power feeding unit to feed the electrical power to the monitoring portion.
