Abstract: A method and apparatus are disclosed for identifying a winner in a bingo game. Players may obtain bingo cards from point-of-sale (POS) terminals that physically prints bingo cards for players in an embodiment where the player appears in person to purchase tickets, or from point-of-sale (POS) terminals that permit players to play bingo in an on-line environment. A game processor maintains a linked list identifying each card in play containing each possible value. Each entry in a linked list includes a pointer to the next element in the linked list. Each bingo card is represented as a bitmap containing an entry corresponding to each square on the bingo card. Each entry in the linked list also identifies the particular square on the bingo card containing the corresponding value, thereby allowing the appropriate entry in the corresponding bitmap to be identified. As each number is drawn, the game processor utilizes the linked list to identify all of the bingo cards in play having the drawn number.

Abstract: An accelerator control for field-controlled DC motors, or other applications requiring non-linear response to linear control input. The control uses a photodetector detecting light reflecting from a movable vane connected to the control input.

Abstract: A gassing detector for use in modifying the charge rate in charging circuits for liquid electrolyte secondary cells. A light is reflected from the surface of the electrolyte into a photodetector. A discriminator circuit distinguishes the pulses in the photodetector output characteristic of the rippling caused by gassing of the cell and produces a signal to cause the charger to reduce the charge rate.
