  • Patent number: 5354069
    Abstract: A lottery by phone system which permits a caller to place bets with a state's existing lottery computer system via a telephone call from a touch-tone telephone which is connected via the public telephone network to a voice response unit which decodes touch-tones entered by the caller. The voice response unit prompts the caller with preprogrammed digitized audio messages and has each caller identified via a unique identification number. It permits such a caller to select which game to place a bet with and to have the option of picking their own numbers or having the system randomly pick numbers for them. It allows the caller to collect their winnings using a touch tone telephone via another telephone call, and to have the automatic interaction with the caller handle data entry errors, and to have caller queries regarding previous such bets answered by an operator.

  • Patent number: 4250533
    Abstract: A security system uses one electronic key that contains many key codes of the user to control several different security devices. Each security device responds to a particular key code or to more than one key code in a master lock system. The key when energized presents its entire repertoire of key codes to the security device and when the security device senses its corresponding code, access is gained. The key may or may not be electrically active. The key may also include mechanical as well as electronic access control. Each security device contains a stored code and electronically correlates the stored code and input pulse patterns of the key codes. A large number of key codes are possible without compromise of system security.
