Abstract: An acceleration detection system for a vehicle includes at least one inertial measurement unit, which includes at least one acceleration sensor configured for measuring an acceleration of the vehicle. The acceleration detection system further includes a temperature sensor configured for measuring a temperature of the inertial measurement unit to obtain a measured temperature. A cooler is configured for cooling the inertial measurement unit in function of the measured temperature.

Abstract: A multiprocessor device includes a plurality of device subsystems each having a processor dependent on a respective other processor in another device subsystem for device operation. Each processor has at least one independent channel for updating a respective software version within the respective processor. A compatibility synchronization module has a database storing a table of compatible software versions for each processor. It is updated when a new software version for a processor is created. This table is independent of software images for the software versions. The compatibility synchronization module is operative for verifying if the software version for a processor is compatible with other software versions at other processors and instructs a respective device subsystem to revert back to a compatible software version within a respective processor or prevent any incompatible software updates within the processor.

Abstract: A method of installing a security system includes activating a security device. An air-borne identification signal is transmitted from the device in response to the activation. The identification signal identifies the activated device. The identification signal is used to ascertain a type of the device. The device is automatically wirelessly configured dependent upon the type of the device.

Abstract: A method of operating a security system includes activating a security device and transmitting a first status report from the device in response to the activating step. A second status report is transmitted from the device after the first status report has been transmitted. The second status report is indicative of a status of an input of the security device. It is determined whether the first status report indicates a status different than the status indicated by the second status report. A third status report is transmitted from the device after the second status report has been transmitted. The third status report is indicative of the input of the security device being in an alarm condition and/or a trouble condition. Dependent upon whether the first status report indicates a status different than the status indicated by the second status report, an alarm and/or a trouble warning are issued in response to the third status report.

Abstract: The present invention is directed to a method and system for providing a residential security system that is also capable of protecting a remote mobile object. The remote mobile object may be a vehicle such as an automobile. The residential security system may include at least one central sensing component for sensing activities within a central environment and central security system controls such as protective state components for determining a protective state of the security system and protective zone controls for defining a protected zone of the security system. The protective zone is extendable beyond the central environment. The system may additionally include at least one selectively recognized remote sensing component located within an automobile remote from the central environment, wherein the selective recognition is dependent upon the protective state and the protective zone controls.
