Abstract: An electrical lock monitoring device which can be retrofitted onto an existing electrical lock control system. The device can be powered by the existing power mains for the electrical lock control system. In the event of a power failure, an indicator is activated to advise users of a power failure. The device can be electrically connected to trigger an alarm, camera, siren, or other devices. Once the power has been restored, the device is automatically reset.

Abstract: An anti-theft lottery ticket includes a substrate, a redemption bar code printed on one side of the substrate, and play symbols printed in a play area on one side of the substrate. The play area is covered with a scratch-off material and a destructible bar code is printed over a portion of the scratch-off material. The portion depends on whether the ticket is a winning ticket or a losing ticket. An enclosure encloses at least one anti-theft lottery ticket, and an activation bar code is attached to the enclosure. Anti-theft lottery ticket methods include scanning the activation bar code, the destructible bar code, and the redemption bar code by a retailer and communicating with an activation-validation database to determine if a lottery ticket is valid and payable.
