Mobile apparatus and power supply system therefor
First Claim
1. A power supply system connectable to a mobile apparatus for controlling the mobile apparatus so as to shift from one power supply state to another power supply state between a power supply ON and a power supply OFF by outputting a power supply control signal in response to a trigger signal, the system comprising:
- control means for controlling the mobile apparatus to maintain the another power supply state for a certain period of time after the power supply control signal is output.

Abstract
When a microcomputer of an electronic control unit determines that an ACC switch undergoes OFF-ON shift, the mobile telephone is controlled to shift the power supply state from the power supply OFF to the power supply ON. If the time passing after the ACC switch undergoes the OFF-ON shift is within a certain period of time, the mobile telephone is controlled to maintain the power supply OFF state. Therefore, even when the ACC switch is turned on and off repeatedly, it is prevented that the power supply of the mobile telephone is turned on and off repeatedly in connection with the repetition of the ON/OFF of the ACC switch.

12. A hands-free apparatus connectable to a mobile phone for operating the mobile phone in a hands-free mode, the apparatus comprising:
-
a power supply system for generating a power-on signal to start an electric power supply to the mobile phone from a power OFF condition when a user-operable vehicle switch is turned on, and generating a power-off signal to stop the electric power supply to the mobile phone from a power ON condition when the vehicle switch is turned off; and
a control circuit for maintaining the power OFF condition and the power ON condition for a predetermined period after the power-on signal and the power-off signal are generated, respectively, irrespective of changes of ON/OFF conditions of the vehicle.
