Abstract: An electronic device includes a housing and a corner structure. The housing is provided with a corner portion and two side edges adjacent to the corner portion. The housing includes an outer surface, an inner surface parallel to the outer surface, and a side surface located at the corner portion and respectively connected to the outer surface and the inner surface, wherein the side surface is a hierarchical curved surface. The corner structure is embedded in the corner portion. The corner structure is provided with an arc-shaped side edge that is aligned with the adjacent two side edges, one side of the corner structure, which is opposite to the arc-shaped side edge, is fitted to the side surface of the housing, and the corner structure is a reinforced material structure.

Abstract: A robot control system includes a signal transmission device and a robot. The signal transmission device has two signal transmission elements that substantially transmit a first signal along a first direction and a second signal along a second direction respectively. The first signal defines a first signal area, and the second signal defines a second signal area. The overlap portion of the first and second signals defines a confinement area. The robot includes a detecting module and a control module. The detecting module detects the confinement area by detecting the first signal and the second signal simultaneously. When the detecting module detects the confinement area, the control module controls the robot to change direction and then move for a distance. Besides, a robot control method applied to the robot control system is also disclosed.

Abstract: A compact camera module includes multiple hollow cylinders, a voice coil motor and a torsion spring. An intervening cylinder is mounted on a base. An upright rail is disposed on the intervening cylinder and perpendicular to a support plane of the base. An inner cylinder has a zoom lens inside and at least one moving component, wherein the inner cylinder is disposed in a hollow space of the intervening cylinder and the moving component slides within the upright rail. An outer cylinder is disposed around the intervening cylinder. The outer cylinder has a sloping rotational rail supporting the moving component. A wire coil is secured around the outer cylinder. A torsion spring encircles the outer cylinder and is secured to the base and the wire coil at two ends. A magnet-generating device is disposed around the wire coil and secured on the base.

Abstract: A driving device and chassis for a disk tray of an optical disk drive is disclosed. The tray of the optical disk drive is connected to the chassis. The front end of the chassis is provided with a driving means. By the driving of the driving means, the disk tray may open or close. A driven wheel serves to drive a decelerating gear set. The driven wheel has a hole that receives a rotary shaft retainer with a thread portion that screws into a boss on the chassis. An upper half of said rotary shaft screw is an axial portion, that extends through the hole in the driven wheel. Alternatively, a rotary shaft retainer may integrally formed with the chassis through a rotary shaft. The chassis is made of a general material. The manufacturing process is easy and the cost of the chassis of an optical disk drive is reduced.

Abstract: A disc player includes a tray motion control module, a traverse module and a dynamic absorber. The tray motion control module supports the tray and, responsive to the instruction, performs in-out operation of the tray. The traverse module, via an isolator, connects to the tray motion control module. The dynamic absorber, via a damper, connects to the traverse module for absorbing the vibration caused by the rotational source on the traverse module.

Abstract: A micro-adjustment apparatus for the spindle motor installation angle in an optical disk player is provided. The optical disk player includes a traverse, and the traverse includes a pickup, a first guide rail, and a framework. The pickup includes a light source for supplying a light beam, and the first guide rail guides the pickup during data reproduction. A spin surface is defined while the spindle is spinning. The micro-adjustment apparatus includes a supporting plate, a pivotal device, a first adjustable pivotal device, and a second adjustable pivotal device. The supporting plate supports the spindle motor and is adjustably coupled to the framework. The pivotal device is disposed at a first predetermined location on the supporting plate and contacts the first guide rail. The first adjustable pivotal device is disposed at a second predetermined location on the supporting plate for adjusting an elevation angle of the supporting plate such that the light beam is substantially vertical to the spin surface.
