A power management device for controlling a power supply device includes a pulse generator, a delay unit, a first XOR gate, an OR gate, and a second XOR gate. The pulse generator generates a pulse signal, the delay unit, the first XOR gate, the OR gate, and the second XOR gate cooperatively generate an enabling signal corresponding to the pulse signal to enable and disable the power supply, and receive an output voltage of the power supply device as a feedback signal. Upon receiving the feedback signal, the power management device can stay at correct enabled and disabled statuses of the power supply device.

An optical film includes a substrate and a plurality of grating structures. The substrate has a light incident surface and a light exit surface opposite to the light incident surface, wherein the light exit surface includes a plurality of semi-cylinder surfaces disposed side by side. The grating structures are disposed on portions of the light exit surface, and an extending direction of each of the grating structures is substantially parallel with an extending direction of each of the semi-cylinder surfaces. The optical film improves uniformity of a plane light source. Further, a backlight module using the optical film is provided.

A backlight module includes a light guide plate (LGP), a light source, and at least one prism sheet. The LGP includes a light emitting surface, a bottom surface, a light incident surface, and a plurality of first microstructures on the bottom surface. Each of the first microstructure is a recessed structure and includes a first surface and a second surface. An included angle between the first surface and the bottom surface ranges from 15 degrees to 27 degrees. An included angle between the second surface and the bottom surface ranges from 50 degrees to 90 degrees. The light source provides a light beam, and an included angle between a light emitting direction of the light beam emitted from the light emitting surface of the LGP and a normal direction of the light emitting surface is greater than 30 degrees. The prism sheet is disposed above the light emitting surface.

A spinning-type pattern-fabrication system comprises at least one carry table used to carry objects, an object-fixing device used to fix the objects onto the carry table, and a control system controlling carry table or at least one laser device. The control system controls the laser device to move linearly back and forth to enable the laser device to fabricate patterns on the objects with the laser beam emitted via the laser device.

A method is provided for detecting connection errors in an Internet telephony gateway (ITG) including a subscriber line interface controller (SLIC). The method includes initializing the SLIC for enabling the SLIC to operate in a forward active state; determining a connection status of the port; enabling the SLIC to operate in a reverse active state if the port is connected; determining whether the SLIC is in an open state after setting the SLIC in the reverse active state; generating connection error information if the SLIC is in the open state, for indicating that a connection error has occurred in the port. An ITG employing the method is also provided.

The present invention discloses a spinning-type pattern-fabrication system and a method thereof. This invention comprises at least one carry table used to carry objects, an object-fixing device used to fix the objects onto the carry table, and a control system controlling carry table or at least one laser device. The control system also controls the laser device to move linearly back and forth to enable the laser device to fabricate patterns on the objects with the laser beam emit via the laser device. Thereby, the present invention provides a spinning-type pattern-fabrication system and a method thereof, which fabricates patterns on multiple objects in a single operation and promotes the speed of pattern fabrication.

An electric power assist device and a driving method for an electric vehicle are provided. The electric power assist device adapted for the electric vehicle includes an angle sensing unit, a driving module, and a control module. The angle sensing unit senses a tilting angle of the electric vehicle on the road. The driving module includes a power driving unit and a motor. The driving module receives a control signal for driving the electric vehicle by the motor. The control module is coupled to the angle sensing unit and the driving module. The control module adjusts the control signal according to a change of the tilting angle to increase a torque force of the motor when the electric vehicle is on an uphill road.
