Abstract: An electronic system for automatically operating the power-operated windows and roof panel in a motor vehicle. Also to provide driver and occupant safety and co]fort by controlling the vehicle's radio/stereo system, air conditioning/climate control system and other selected systems in response to calls placed or received on the vehicle's cellular phone or in response to changes in the vehicle's interior or exterior environment or both.

Abstract: The environmental signal switch is an electronic device primarily for automotive use which is responsive to the absence of daylight and moisture. The device is designed to send a signal to selected electronic devices, namely the gates of scr's to activateselected electrically operated devices. The switch is designed to send a signal to one or more scr gates only, in response to moisture, and send signals to the same said scr gates, and one or more additional scr gates in response to the absence of daylight. The device as used in automotive application is to allow for the closing of windows and roof panel in response to rain regardless to whether keys are left in the ignition. In response to the absence of daylight, said windows, roof panel, and door locks are activated, provided said keys are removed from the ignition. The switch can activate the said electrical devices directly or indirectly, by said means of activating the gates of said scr's. The said scr's can be part of an environmental security system.

Abstract: The Automatic Memory and Environmental Security System is a solid state electronic device to be employed in a motor vehicle for the specific purpose of closing any and all electrically operated windows, and roof panel, and locking any and all electrically operated door locks, which may have been left open or unlocked purposely or inadvertently. The system is also designed to close any and all electrically operated windows and roof panel left open when the surrounding humidity reaches 100% (the appearance of rain, drizzle, etc.). The unit is designed so that there is no interference with the normal operation of the above-named electrical device(s) after being employed in the said vehicle.
