Abstract

This device utilizes GaAs light-emitting diodes for identification and lock-actuating mechanisms. To identify or match identification, such diodes are arranged in sealed plastics or other materials such as conventional keys or cylinder plugs to be detected by photocells which, in turn, actuate a security device. Power from small batteries actuates the diodes or power can be made available from the locking mechanism itself.

Security Identification and Lock Actuating Device

This device utilizes GaAs light-emitting diodes for identification and lock- actuating mechanisms. To identify or match identification, such diodes are arranged in sealed plastics or other materials such as conventional keys or cylinder plugs to be detected by photocells which, in turn, actuate a security device. Power from small batteries actuates the diodes or power can be made available from the locking mechanism itself.

In drawing A, plastic identification card 2 contains a number of GaAs diodes located at various positions within card 2 as indicated at 3. Card 2 also contains batteries 5 and activating switch or button 6. Upon insertion of card 2 into a receiving device not shown, power is supplied to diodes 3 from batteries 5 by contact 6. Diodes 3 in turn emit light through the transparent or translucent surface upon card 2, which can be received by photocells within the receiving device. Thus, card 2 can be utilized as an identification card. In an alternative shown in drawing B, contacts 1 upon the card 2 connect with a power source within the receiving device to activate the diodes 3. identification is made in the same manner as with the card in drawing A. Such cards can be utilized to open locks, identify personnel making rounds, for security checks. Such a card can also be used to identify a credit card holder.

In drawing C, a key 10 has GaAs diodes 11 located at certain points upon the key face. Press...
