Abstract: An alarm system having the capability to self-adjust or self-calibrate itself is disclosed. The system includes an alarm controller and at least one sensor that generates a signal that corresponds to the magnitude of a detected event. The signal evaluator is part of the alarm controller and receives the magnitude signal from the sensor. The signal evaluator compares the magnitude signal to a user-defined or preset alarm sensor sensitivity threshold and generates an alarm signal if the magnitude signal exceeds the alarm signal sensitivity threshold. If repeated alarm signals are generated, an alarm threshold adjuster will adjust the sensor sensitivity threshold to a point where repeated magnitude signals will be ignored. The system will reset itself to the original user-defined or preset sensor sensitivity threshold levels after a predetermined time of no alarm signal generation. The alarm signals generated will activate an alarm annunciator, which generates an alarm.

Abstract: A hand-held sound-activated system for remotely activating the functions of a vehicle or other item is disclosed. The system provides for an apparatus, such as a key fob, that houses a sound recognition controller and a microphone capable of receiving, comparing, processing, and remotely transmitting a signal to activate a desired function. The apparatus contains a microphone activator, a sound digitizer for digitizing sounds such as passwords and commands into a digital code, a digital memory for storing the digital codes for valid and authorized sounds, a sound recognition comparator for comparing and determining the validity of a subsequently received sound with those stored in the memory unit, and a transmitter for transmitting a signal to the vehicle or building to activate the desired and authorized function. Indicators of successful operation, such as LEDs, may also be included.

Abstract: A hand-held programmer that is adapted to interface with a variety of vehicular accessories is disclosed. The device allows a user to preselect the desired settings for a particular accessory and then program that accessory with the push of a single button. The programmer also provides for an operable connection to a manufacturer's technical support computer via the Internet whereby software updates may be downloaded to the vehicular accessory and data for remote diagnostic troubleshooting may be exchanged between the manufacturer and the installer.
