Abstract: An electronic device that functions as an area-intrusion informing device for announcing the unauthorized entry into an enclosure or area which has at least one access opening and closing means. The device uses components that are small for inconspicuous insertions, or for surface mounting, and preferably utilizes a dummy hinge arrangement as an electrical conductor between the various components. The device is used for access doors, windows, filing cabinets, desk draws, closets, and the like, and typically includes at least one light emitting diode, an optional numeric liquid crystal display, a timer, and alert signaling and reset components. The components act together to provide notification of illegal entry between the times of departure, and arrival, of authorized users of the enclosure or area. A simple security alert system is provided.

Abstract: A leverlock system is provided wherein an enclosure can be locked for a specified time period using a simple locking arrangement. The leverlock is intended to be used in conjunction with existing locking systems, and allows a user to restrict entry to anyone, including those who might otherwise be authorized to enter the enclosure, over a specified time period. A timer module is provide which activates a solenoid connected to a locking apparatus is provided, and the timer module controls the activation of the solenoid so that entry into the enclosure is only permitted for a selected interval duration, at a specific time. The leverlock system is also preferably accompanied by an Electrical/Electronic Switching System having a circuit which can be energized or de-energized by using a Random Access Memory—(RAM) Recognition Switching System™.

Abstract: The present invention relates primarily to the provision of a Sound Proof Chamber (10), and optionally also relates to an Electronic Surveillance Bug Proof Chamber. Both embodiments comprise a sealed cavity located within all walls, roof, and optionally the floor surfaces of said chamber, which cavity is kept under a Partial Vacuum. The type of chamber which is fabricated is dependent on its intended use. For example, in high level applications, an additional combination of absorbing acoustic, and radio frequency blocking surfacing, and electronic sounds detector can be used to further restrict or detect the transmission of sounds within said enclosure. In lower level applications, the vacuum cavity may have sufficient noise suppression capability. The chamber is of the present invention is preferably manufactured using modular components in an assembly kit form in order to provide the consumer with a variety of chamber shapes, colors and incremental sizes.

Abstract: The principal object of the present invention relates primarily to the provision of a Sound Proof Chamber (10). Secondly to an Electronic Surveillance Bug Proof Chamber. The latter being an enhancement of the former embodiment. Both embodiments having a sealed cavity within all surfaces of said chamber that form the plastic enclosure, and to subject said cavity to a Partial Vacuum of Specified Pressure. The type of installation required is indicative of its intended use. For high level applications, a combination of absorbing acoustic, and radio frequency blocking surfacing, and electronic sounds detector are used to restrict or detect the transmission of sounds within said enclosure.
