20080218366SYSTEM AND METHOD FOR PROTECTING PORTABLE ELECTRONIC DEVICES - A system for protecting a portable electronic device includes an accelerometer and a processor. The accelerometer is configured to measure an acceleration of the portable electronic device in at least one direction and to generate a signal proportional to the acceleration. The processor is configured to receive the signal from the accelerometer and compare the signal with a preset value to judge whether an unacceptable fall and/or an unacceptable impact is occurring. The processor is further configured to activate a routine to shut down the portable electronic device, if such a fall and/or an impact is occurring. The goal is to prevent, e.g., system shorts that may otherwise occur from impact from potentially further damaging the device.09-11-2008

20100134969PORTABLE COMPUTER AND HINGE MECHANISM THEREOF - A portable computer and a hinge mechanism thereof are provided. The portable computer includes a display monitor, a host and a hinge mechanism. The hinge mechanism for rotating the display monitor and the host relatively includes a bottom board, a pivot, a power adapter, a locking bracket, a slanting board and a parallel board. The pivot is disposed on the bottom board. Two ends of the pivot are connected with the host and the display monitor respectively. The power adapter is disposed on the bottom board. The locking bracket having a locking hole is disposed on the bottom board. The slanting board disposed on the bottom board slants to the pivot. The slanting board has a first opening which exposes the power adapter. The parallel board disposed on the bottom board is parallel to the pivot. The parallel board has a second opening which exposes the locking hole.06-03-2010
20100134970PORTABLE COMPUTER AND HINGE MECHANISM THEREOF - A portable computer and a hinge mechanism thereof are provided. The portable computer includes a display screen, a host and a hinge mechanism. The hinge mechanism is connected with the display screen and the host. The hinge mechanism is used for rotating the display screen around the host. The hinge mechanism includes a bottom board, a pivot, a network connecter and a slanting board. The pivot is disposed on the bottom board, wherein one end of the pivot is connected with the host and the other end of the pivot is connected with the display screen. The network connecter is disposed on the bottom board. The slanting board is disposed on the bottom board and slants to the pivot. The slanting board has an opening which exposes the network connecter.06-03-2010
20100136398PORTABLE COMPUTER AND LOCKING MECHANISM THEREOF - A portable computer and a locking mechanism thereof are provided. The portable computer includes a battery, a host and a locking mechanism. The battery has a locking hole. The battery includes a restraining protrusion. The host has a receiving through. The locking mechanism is disposed in the receiving through. The locking mechanism includes a main body and a locking protrusion. The main body has a first restraining concave and a second restraining concave. The locking protrusion is connected to the main body. When the restraining protrusion is placed in the first restraining concave, the locking protrusion is locked in the locking hole, so that the battery is locked in the receiving through. When the restraining protrusion is placed in the second restraining concave, the locking protrusion leaves the locking hole, so that the battery is dismounted from the receiving through.06-03-2010

20100213883VARIABLE-DELAY-TIME CONTROL SYSTEM FOR A MOTOR - A variable-delay-time control system for a motor is provided. The system includes a control unit, a driving unit, and a motor. The control unit is used to output at least one control signal according to at least one predetermined signal, and the control signal has a variable delay time. The driving unit is connected to the control unit, and is used to receive the control signal and generate a driving signal. The motor is connected to the driving unit, and conduction time of the motor is controlled according to the driving signal and the variable delay time. With the variable-delay-time control system of the present invention, the delay time of the control signal is variable, so the motor can operate at a high efficiency (for example, at a reduced current). Moreover, as the variable-delay time can be adjusted according to the predetermined signal, the motor can operate at a high efficiency in different operating states, thus improving the overall efficiency of the motor.08-26-2010
