An electronic device includes a first supply target unit that accepts supply of power from an external power supply, a second supply target unit that accepts supply of power from a battery, a main body, and a controller, wherein the controller starts to accept supply of power from both the external power supply and the battery and starts to output, to the main body, a voltage of the power supplied from both the external power supply and the battery in a case where a predetermined time has elapsed since start of a predetermined operation of the main body while a voltage of power accepted from the external power supply has been output to the main body.

Electronic device and method of controlling electronic device

Provided are a toilet seat device saving energy and accurately stabilizing the temperature of a seating section at a predetermined level in a short time, and a toilet apparatus having the same. A control section adjusts the temperature of a toilet seat section to 18&#xb0; C. when a heating function is turned on, and during a standby period D, the control section performs low electric power drive of a lamp heater provided at the toilet seat section. The control section starts 600 W drive of the lamp heater at time tafter the control section detects user's entry into a room, and the control section maintains the 600 W drive during an inrush current reduction period D. The control section starts 1200 W drive of the lamp heater at time tand maintains the 1200 W drive during a first temperature rise period D. After the temperature of the seating section reaches limit temperature, the control section starts 600 W drive of the lamp heater at time tand maintains the 600 W drive during a second temperature rise period D. After the temperature of the seating section reaches a temperature higher than a toilet seat set temperature, the control section starts low electric power drive of the lamp heater at time t

Toilet seat device and toilet seat apparatus having the same

A human body detector for a seat which does not deteriorate comfort of sitting even when it is disposed on the seat, has a high sensitivity and can be easily fitted to the seat. Vibration detection means (,) is disposed in such a manner that even when a person is seated, the means (,) comes into contact with the bottom surface of a seat pad (,) of a seat (,) and accordingly the person does not feel the means (,). According to this construction, the human body does not easily feel the means (,) by the provision of the seat pad (,), the existence of the vibration detection means (,) is hardly felt even when the hardness and the shape are changed, and various measures for improving the sensitivity of the vibration detection means (,) can be taken. The vibration detection means (,) may be merely bonded to the seat pad (,) or may be fixed to a seat spring (,) or a seat frame (,), and can be fitted more easily to the seat (,) than when it is disposed below a surface cloth (,) of the seat (,).
