  • COVER MECHANISM AND ELECTRONIC DEVICE USING SAME
    Publication number: 20090270144
    Abstract: An electronic device (100) using a cover mechanism (30) to cover its hole (14) of its housing (10) is described. The cover mechanism includes a cover (20) and a locking structure (11). The cover has a latching portion (23) and a locking portion (21), both of which include a resilient part. The locking structure is configured for associating with the locking portion and the latching portion. Thus, the cover is latched to the housing to cover the hole by deforming the resilient parts. After the cover is unlatched from the housing by a sudden pulling force, the locking portion still physically connects to the locking structure. After the cover is unlatched from the housing by a normal pulling force, the locking portion has no physically relationship with the locking structure.

  • Vehicle anti-theft system and method
    Publication number: 20090189750
    Abstract: In a vehicle anti-theft system, a vehicle-mounted mainframe downloads a sole identification code, serving as a control identification code, and transfers the sole identification code into a part as a part identification code. The vehicle-mounted mainframe determines if the control identification code is obtained when the vehicle is activated. If yes, the vehicle-mounted mainframe sends a request command to the part to obtain the part identification code. The vehicle-mounted mainframe determines if the part identification code meets with the control identification code. If yes, the vehicle-mounted mainframe produces a normal operation signal to enter a normal operational mode and feedbacks the identification code to the customer service center. The customer service center checks with a database for stolen events.
