    Abstract: A programmable electronic lock and key in which the key consists of a card having non-visible coded indicia thereon designating an address in memory and the contents thereof. The lock includes a card reader for scanning the coded indicia, memory means storing arbitrary patterns at designated locations; and means for comparing the scanned card data and the data extracted from the memory address specified by the card. A mismatch indicates a nonvalid key.

    Abstract: An elastic diaphragm switch is operated by moving a ribbon along a predetermined path obstructed by a bearing surface on a hammer. A projection on the ribbon presses against the bearing surface on the hammer, displacing the hammer against a spring supporting the hammer. Once the hammer is fully displaced, the ribbon passes beyond the bearing surface releasing the hammer to strike the elastic diaphragm of a switch, thereby momentarily closing the elastic diaphragm switch.

    Abstract translation: 通过沿着由锤子上的支承表面阻挡的预定路径移动带来操作弹性膜片开关。 色带上的突起压在锤子上的支承表面上,使锤子抵靠支撑锤子的弹簧移动。 一旦锤子完全移位,色带越过轴承表面就释放锤子,以撞击开关的弹性隔膜,从而暂时关闭弹性膜片开关。
