Abstract: A method for verifying tampering of an electronic device by a third party who picks up and attempts to unlock the device when the device is inadvertently left in a place by the owner of the device. The method comprises an application software downloaded within the device that senses the movement of the device when picked up by a third party and triggers the bidirectional cameras within the device to silently start capturing images of the third party and video record the tampering actions which are time and date stamped, uploaded to a cloud source and sent by text and email to a second device for review of the tampering of the device, and identification of the third party who tampered with the device.

Abstract: An electromagnetic lock assembly locks sliding double doors having abutting edges when closed. The lock assembly includes an armature plate member mounted through an L-shaped bracket member to a first sliding door adjacent an abutting edge thereof. An electromagnetic body member is mounted through another L-shaped bracket member to a second sliding door adjacent an abutting edge thereof. The armature plate member and electromagnetic body member are in register contact with the sliding double doors closed. The electromagnetic body member includes an electrical conductor portion movably contacting a stationary, linear power strip member mounted to a nonmoving support adjacent to the second sliding door. Electrical power is maintained to the electromagnetic body member of the lock assembly by the electrical conductor portion thereof, movably contacting the stationary power strip member upon movement of the sliding double doors.

Abstract: A card has a printed face, a back, and a fold line which divides the card into a main portion and a flap which is foldable over the fold line so that the back of the flap is flush with the back of the main portion and the face of the card has the shape and appearance of a conventional business card. An adhesive layer is disposed on the back of the card so that with the flap open the adhesive may be exposed and the card removably adhered to a smooth vertical surface, juxtaposing the face of the flap and an auxiliary message printed upon the same with the face of the main portion. Removal of the card from the surface and either folding of the flap or separation of the same from the main portion converts the card back to one which has a face that has the shape and appearance of a conventional business card.
