US 8,102,737 B2 · Power saving method for optical disk drive of rugged electronic device

Abstract

A power saving method for an optical disk drive of a rugged electronic device is described. In the method, whether a watertight lid outside the optical disk drive is in open/closed state is detected by a sensor. When the watertight lid is in the closed state, whether an optical disk exists in the optical disk drive is detected by a read/write head of the optical disk drive. When no optical disk exists, a controller in the rugged electronic device begins to time. When a predetermined time is reached and no optical disk drive start command is received, the controller turns off an electrical connection between a power supply and the optical disk drive. When an optical disk drive start command is received, the controller enables the electrical connection between the power supply and the optical disk drive.

Dependent claims

A power saving method for an optical disk drive of a rugged electronic device, wherein the rugged electronic device having a watertight lid openably connected to the rugged electronic device and disposed outside the optical disk drive, the optical disk drive being electrically connected to a power switch, the power switch being electrically connected to a power supply, and the rugged electronic device having a controller for confirming whether an optical disk drive start command is received, the method comprising:

detecting, by a sensor, whether the watertight lid is in an open state or a closed state, wherein, when the lid is closed, the sensor generates and sends to the controller a first detection signal corresponding to a closed state of the watertight lid;
detecting, upon the closed state of the watertight lid, whether an optical disk exists in the optical disk drive with a read/write head of the optical disk drive;
timing a predetermined time by the controller when the read/write head confirms that no optical disk exists;
and
sending out a first control signal to the power switch by the controller to turn off an electrical connection between the power supply and the optical disk drive after the predetermined time is reached.

A power saving system for an optical disk drive of a rugged electronic device, comprising:

an optical disk drive, disposed on one side of the rugged electronic device, and selectively electrically connected to a power supply of the rugged electronic device, wherein the optical disk drive comprises a read/write head for detecting whether an optical disk exists in the optical disk drive;
a watertight lid openably connected to the rugged electronic device and disposed outside the optical disk drive;
a sensor, detecting a position state of the watertight lid and generating a first detection signal corresponding to a closed state of the watertight lid or a second detection signal corresponding to an open state of that the watertight lid;
a controller, electrically connected to the sensor for confirming an optical disk drive start command, wherein upon receipt of the first detection signal from the sensor and upon confirmation that no optical disk exists in the optical disk drive, the controller starts to time and generates a first control signal after a predetermined time is reached;
and
a power switch, electrically connected between the optical disk drive, the power supply, and the controller, wherein the power switch turns off an electrical connection between the power supply and the optical disk drive according to the first control signal.
