Abstract: This is directed to methods, systems, and apparatuses for implementing circuitry that can be used to control multiple solar cells to generate power for a portable electronic device. For example, in response to determining that one or more of the solar cells is generating a reduce voltage output (e.g., due to a partial obstruction of one or more of the solar cells), the connections among the solar cells can be configured to generate a constant preset voltage, as long as a subset of the solar cells is operating. The voltage generated by the solar cells can then be boosted to a value suitable for powering the portable electronic device and/or any of its individual components. As another example, the connections among the solar cells can be configured to generate a startup voltage to directly power the portable electronic device and/or any of its components.

Abstract: A drive control apparatus automatically stops a drive power source operation of a vehicle under a predetermined operation condition. When a predetermined time period lapses after the automatic stop operation of the drive power source under a condition that a key switch is still held operated, a power supply from a battery to the drive control apparatus is also automatically stopped. The predetermined time period is set to a time period that is supposed necessary until a driver or the like notices the stop of the drive power source and turns off the key switch. Thus, after the drive power source is forced to stop, the battery is protected from unnecessary power consumption by various devices in the vehicle.
