Abstract: The auxiliary control system contains at least a first interaction device and a second interaction device that are capable of mutually detecting the presence of each other by a wireless means. The first interaction device is carried by a driver of a motor vehicle having a built-in anti-theft system, and the second interaction device is tapped into a Main Body ECU in parallel with the original control interface of the built-in anti-theft system. As such, when the driver carrying the first interaction device enters into or moves out of an effective sensing range from the motor vehicle, the second interaction device would detect the presence or absence of the first interaction device. The second interaction device then issues appropriate deactivating or activating signals to the Main Body ECU which in turn disarms or arms the various anti-theft means of the motor vehicle.

Abstract: An electrical wire connection device includes a housing having a top surface and opposite end surfaces that respectively intersect the top surface at end edges of the top surface. Each end edge forms a cutoff. A cover board is openably closed to the top surface of the housing to expose an opening of the cutoff in the respective end surface. The opening allows the insertion of a tip of a hand tool, such as flat-ended screwdriver, to pry the cover board open. In this way, the cover board can be opened easily and efficiently without damage to the housing or the cover board.

Abstract: An assisting ejection device is provided for assisting ejection a hatch of a hatchback. The assisting ejection device includes spring-biased rod to act on the hatch. The spring is in a compressed condition when the hatch is closed so that when the hatch is released from the closed condition, the spring that is allowed to extend provides a springing force to help pneumatic cylinders that are originally provided to automatically lift the hatch to eject the hatch toward a flip-up position. The springing force effectively reduces the load applied to the pneumatic cylinders in opening the hatch so as to extend the service life of the pneumatic cylinders.
