An addressable monitoring system and method for addressing sensors. In one embodiment, the invention provides an addressable monitoring system for a vehicle. In one embodiment, the system includes a plurality of sensors each having at least one address input; a harness; and a controller. The harness includes a common bus coupled to each of the plurality of the sensors. Each sensor is operable to determine its own address according between the sensor and the harness. The controller sends a signal having address information and control or command information through the harness. The sensor having an address that corresponds to the address information in the signal sent by the controller responds. The system is applicable to a tire pressure monitoring system having multiple sensors, one sensor located on or in each tire. Each sensor may be paired with an addressable initiator located in the proximity of the tire.

Addressable vehicle monitoring system and method

A remote signal transmitter that is capable of producing a command comprising a signal including a first value and an answer calculated using the first value as an input variable in a transfer function. The transmitter broadcasts the signal to a receiver which receives the first value and the answer. The receiver then performs a second calculation using the first value to produce a second answer. The first answer incident upon the receiver is then compared with the second answer and if a predetermined comparison test is satisfied, the subsequent command is implemented. The preferred embodiment of the present invention includes a means to increment the first value each time the transmitter is utilized. In addition, the receiver includes a screening process in which the second calculation performed by the receiver will not be performed if a previously used first value is received.

Apparatus for remote implementation of a command

A security system for an automotive vehicle having an engine is operatively connected between engine running electrical components which are connected to an electrical power source and a lock switch having at least two operative positions. The security system has a lock switch operator having a memory device carried thereon with a first security code stored in the memory device. A theft control module having a memory storing a second security code is operatively connected between the switch and the engine running electrical devices. The theft control module operates to first permit the engine running electrical components to enable the starting of the engine and then to compare the first and second security codes. Upon finding the first security code not equal to the second security code, the engine running electrical components are disconnected from the electrical power source which disables the engine.

Method and apparatus for an automotive security system which permits

A method for programming a lock to accept a key. The device will erase all the codes currently stored in the memory and program a new key value. The process requires several steps of turning the key to one of two positions when an LED is illuminated to indicate that the key must be rotated. After successful responses, all the codes currently stored are cleared and the security code of the new key is stored.

Method and apparatus for programming a spare key into a security system

A method for programming a spare key containing an electronic coded security code into the memory of a security system whereby a known key is inserted into the lock cylinder and the security device is triggered to read its encoded security code. If within a period of time an unknown key is inserted into the lock cylinder, the encoded security code of the unknown key is then inserted into the system memory. The new key security code becomes an additional acceptable security code to open the lock in response to receiving the first (authorized) security code.
