Abstract: A multi-purpose automatically rewindable sun-shade devised to have a quite long resilient curtain which is wound around a winding tubular shaft when it is not in use. The curtain may be pulled out to a needed length for use and rewound automatically on the winding shaft by twisted coil springs. The sun-shade comprises an elongated winding tubular shaft for winding a long curtain thereon, two immovable rods adapted to extend in the interior of the winding shaft, two coil springs fitting around the immovable rods in the winding shaft to generate tension when twisted. The tension force rotates the winding shaft to rewind the curtain after use. The shade has two sleeves assembled around the winding shaft and forming a central through hole for a square end of each of the immovable rods to pass through to engage a central square hole in each of two shaft caps assembled with the two sleeves so that the sleeves and the winding shaft can rotate together between the two shaft caps.

Abstract: A prealarm system is provided for an anti-theft alarm where a signal from a displacement/vibration detector is picked up by a one-shot timer circuit. If no other activation signal is picked up after the first signal is received a main control alarm circuit is activated for (1) driving a siren circuit to generate a short chirp sound as an audible warning, and (2) a flashing circuit to flash a light for a preset period of time as a visible warning. If the number of activation signals received subsequent to the first are greater than a predetermined threshold number, or the activation signal continues for a predetermined period of time, the main control alarm circuit is activated for driving, (1) the siren circuit to give a normal audible signal alarm, and (2) both, the flashing circuit for flashing a light and the dome light control to provide visible signals.

The radiation 26 is then sensed through the window 22. In the preferred embodiment the window 22 is positioned with an optical path along the center axis of the conduit 14. Other systems and methods are also disclosed.

Abstract: An error-free control circuit for burglar alarm detectors which eliminates false alarms and facilitates setting the sensitivity of the detectors by providing an audible pre-warning signal via some alarm warning device to indicate false alarms and impending violation by a burglar an alarm signal from an alarm upon actual violation by a burglar. When the detector detects a false alarm condition, a pre-warning audible signal is sounded by the alarm warning device for easy sensitivity setting during installation. When the detector detects the sounds of tampering to the car, a pre-warning audible signal is sounded by the alarm warning device to warn the would-be burglar that the premises are protected by an armed alarm. Finally, when the detector detects actual violation of the protected premises, the alarm sounds to scare the burglar away. By this means, an alarm detector can be set to give optimum performance under any condition.

Abstract: The invention is a two-step alarm disarming device with automatic rearming which uses sensors and buffer circuits to detect the condition of the car doors, hood, and trunk. It can disarm an alarm in two steps--with a signal input to an exterior key switch buffer for temporary disarming and a signal input to the ignition for permanent disarming. It is comprised of two-step alarm disarming circuits, a flip-flop, a timer, and a buffer for alarm disarming so that the burglar alarm can operate at maximum effectiveness without failure due to external interference or user negligence.

Abstract: A vehicle alarm control system built into a single integrated circuit, which includes a number of inputs including M/D-, INO-, INO+, H/T-,C.S+, and INC- which monitor a plurality of sensors strategically placed around an automobile; a fail safe/override/memory circuit which prevents the alarming of the alarm should any of the inputs become defective but allows the user to temporarily disable the defective input; and instant trigger override control which allows the user to cause the sensors to instead trigger the alarm after a delay upon the opening of the door; a main power cut warning control which triggers to provide an audible warning signal should the alarm be removed; a per-entry alert control which triggers an audible warning immediately should the automobile's door handle be touched while the alarm is armed; and a headlight on warning control which causes the alarm to give an audible warning if the automobile's headlights are on after the automobile's engine is turned off.
