  • Publication number: 20240125148
    Abstract: A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock.

  • Patent number: 8502639
    Abstract: A resistor, fabricating method, and thermal sensor material for resistors that incorporate high Temperature Coefficient of Resistance (TCR) values and low resistivity for better sensitivity in infrared imaging applications are disclosed. Amorphous oxide thin films, preferably oxides of vanadium (VOx), were deposited on thermally grown silicon dioxide by direct current (DC) magnetron co-sputtering of noble metals (gold and platinum) in a controlled argon/oxygen atmosphere. The ideal conditions for preparing an amorphous vanadium oxide/noble metal thin film are identified. TCR and resistivity results showed that the additions of gold (Au) and platinum (Pt) into VOx reduced the resistivity. However, only gold (Au) was found to improve TCR value. Reducing the amount of oxygen in the thin film, further improved the ratio between TCR and resistivity. Infrared detection and imaging devices can be greatly improved with a “drop-in” amorphous vanadium oxide/noble metal thin film of the present invention.
