Abstract:
The present invention relates to a brushless motor system. The brushless motor system has a brushless motor, a motor driver, and at least one sensing circuit. The brushless motor has a rotor, and the sensing circuit is used to detect the rotor position. The sensing circuit has a Hall sensor and two capacitor devices. The Hall sensor has two output ports. As the rotor rotates, the Hall sensor will generate a sensing signal at each of the two output ports. Each of the capacitor devices is connected in series to one of the two output ports of the Hall sensor, and the two capacitor devices are used to filter out DC biases in the two sensing signals. The motor driver is connected to the two capacitor devices for driving the rotor of the brushless motor according to the two sensing signals from the two capacitor devices.

The method includes: firstly, dividing the flash memory into a primary storage area and a backup storage area, wherein the difference between a first start address of the primary storage area and a second start address of the backup storage area is an offset address not equal to zero; reading the flash memory according to a address pointer equal to the first start address so as to obtain the boot data; making the electronic apparatus perform a boot sequence according to the boot data; then, detecting whether the boot sequence is normal or not, and when the boot sequence is abnormal, providing the flash memory with changing the read pointer to the second start address according to an offset address to read the backup boot data.
Abstract:
A flexible flat cable and a disk drive using the same are provided. The flexible flat cable is configured to suppress an electromagnetic interference (EMI) generated by a signal transmitted by it. The flexible flat cable includes a main body and a metal layer. The metal layer is disposed on the main body along the direction the signal is transmitted. The width of the metal layer along the direction, perpendicular to the direction the signal being transmitted, is smaller than the width of the main body.
Abstract:
This invention relates to a optical storage carrier player cover-locking mechanism and method, which provides a optical storage carrier player cover that can actuate a locked state to prevent a optical storage carrier from rotating as cover is being lifted up and a lifting-up state for putting or removing a CD. This CD cover arranges: a driving element that connects to the CD driving apparatus and makes it rotate, a controller that adjusts rotation speed of the driving element, and a switch that can touches off the controller to proceed a controlled motion with predetermined rotation speed. By touching off the switch, the controller can detect the rotation speed of the driving element. By comparing the detected rotation speed with a predetermined speed in the controller, when rotation speed is higher than the predetermined speed, the controller generates a signal to the driving element to reduce the rotation speed of motor. And when rotation speed is lower than the predetermined speed, a signal is generated to actuate a cover-lifting motion to the CD cover that is then in an open state.
Abstract:
A trigger mechanism is provided for triggering an eject device of an electronic equipment with a front panel door. The eject device ejects a tray device, movably seated within the space of the electronic equipment, out of the electronic equipment when triggered. The trigger mechanism cooperates with the front panel door to trigger the eject device. The trigger mechanism works to trigger the eject device when a predetermined displacement of the front panel door form a normally closed position takes place. According to the invention, user can eject the tray device of the electronic equipment only by pressing the front panel door of the electronic equipment such that mistaken pressing of another functional button set on the front panel of the electronic equipment and possible cut of user's hand can be prevented. The trigger mechanism is composed of several simply mechanical components replacing a conventional trigger mechanism via a button such that manufacture cost of the electronic equipment can be reduced.

Abstract:
The present invention relates to an airflow guidance structure in an optical storage carrier player. More particularly, the present invention relates to an airflow guidance structure in a CD-RW drive. The airflow guidance structure provides a path and cooperates with outlets disposed close to the end of the airflow guidance structure. Heat generated during the operation of the CD-RW drive is discharged from the outlets by using the airflow generated by the rotation of the disc.
