Abstract: A remote controller casing includes a front shell; a rear shell, which has an assembly means with the front shell, wherein the assembly means is coupled and fixed for the rear shell and the frond shell to develop an accommodating space to hold a printed circuit board, and the rear shell further comprises a battery bay whose one interior edge is designed to have a convex part, at least one concave part at one side, and a groove corresponding to the concave part and located at an opposite side; and a back cover, which includes at least one clasper at one ide which is opposite to the concave part, and at least one clamping part at an opposite side.

Abstract: A method includes detecting the parking light system of a car to achieve the theft-proof function. It can detect and learn the how many flashes, the turn on/off time in each period and the voltage value of the parking light, which is produced when using a keyless transmitter module to lock/unlock the car door. And the system can be easily installed by setting up just one line collaborating with a smart learning module with a CPU inside and without corrupting the original structure of a car.

Abstract: A remote illuminant multifunction controller including transmitter, illuminant switch and high brightness LED bulb. The high brightness LED bulb is built in front of the transmitter, together with the illuminant switch in the same side. The high brightness LED bulb can be simply switch on and off by using the illuminant switch. The control penal is built on top of the transmitter to control the sensed object. A user will be able to control the sensed object easily by using the present transmitter that is also a handy illuminant tool. The remote illuminant multifunction controller utilized and combined remote control and illuminant tools, hence to replace the traditional remote controller and torch.

Abstract: A remote control security system includes a remote control unit, a receiving unit, and an operation unit connected to the receiving unit for performing or cancelling an alarm function. A combination code having a basic code and two sets of remedy codes is produced by an encoder. When the receiver has received the signals from the remote control unit, a decoder compares the basic code and the two sets of remedy codes received by the receiver with a reference basic code and two sets of remedy codes generated by the encoder and, if the received and reference codes match, the decoder sends a control signal to the operation unit. One of the remedy codes is varied by a counter once each time the remote control button is pushed and the other is varied by the counter during the time that the button is being pushed.

Abstract: An integrated security door lock system which combines a vehicle security system with a remote controlled engine starting system so as to start a vehicle's engine, air conditioning; and to start an engine at a preset time or temperature and the alarm system of a vehicle by way of a remote control transmitter.

Abstract: An improved remote control vehicle security system performing an override re-arm function enables a disarmed security system in which siren alarming, parking light flashing and other sensor trigger system and etc. are stopped to function for a preset period of time, such as 30 seconds, if no further input to cancel the override re-arm is given within the preset period of time, the system will resume an armed state automatically.

Abstract: A vehicle security system with anti-robbery function which has a mainframe including a software stored in a CPU and preset code recorded in a permanent memory unit. A key receiving means is electrically connected to the mainframe and a contact-type relief key also provided with a corresponding code which must match the preset code in the permanent memory unit to start the engine of a vehicle. The key receiving means is provided with a button and at least one relay is housed in the mainframe. Once the button is pressed, the security system enters an anti-robbery mode, and after a preset period of time, the CPU will make the horn of the vehicle honk and the head light and direction indicating lights flash continuously.

Abstract: A key, a timer and a signal emitter are integrally produced as one single item. The key with a timer and an emitter can facilitate a person to carry these items in one piece and make the use of the same with readiness.

Abstract: An automobile alarm system with noise reduction function utilizes a built-in function in a single-chip computer, which is adapted to control the alarm system, to prevent the system being damaged by the noise, while the noise is presented in the form of high voltages, occurring during the operation of the engine. The alarm system has a current detector circuit to sense the presence of noise, and a one-shot circuit to selectively activate/inactivate the single-chip computer temporarily.

Abstract: An improved central lock control system adapted for automatically locking and unlocking all the four doors by way of operation on the lock knobs mounted on the two front doors, and only permitting to automatically unlock all the four doors by way of operation on the lock knobs mounted on the two rear doors for safety consideration; the present lock control system is characterized in that the motor, used to control the motion of an actuator which enables the lock knobs of the doors to perform the locking and unlocking operation, is able to spin clockwise or counter clockwise to generate an inductive voltage on the lock knob being pulled up to unlock or pushed down to lock the doors; the generated inductive voltage is input into an electronic module for logic comparison so to effect the above cited control operation; whereby the control circuit is simplified to a large extent and the mounting of the present system is made easy; besides, the production cost is effectively lowered as a result of the removal of a
