A game switch particularly useful as a bingo table used by a bingo caller has greatly increased reliability over conventional microswitch actuated tables. A matrix of conductive flexible strips are used, whereby when a ball is depressed at an intersection of a vertical and horizontal strip, a contact is made. The resistance of the contact is particularly suitable for use with CMOS gate inputs to an electronic matrix position determining circuit.

A defect detection system includes a video camera with defect detection circuits for detecting defects in video signals being outputted by corresponding sections of an array sensor such as a TDI CCD two-dimensional array sensor. Each defect detection circuit includes a subtraction circuit for subtracting a prior stored pixel from an incoming pixel to generate a difference. Comparators compare the difference with positive and negative limits defining an acceptable range of difference values. The prior stored pixel is updated to the succeeding pixel only when the difference value is acceptable. Memories store the defect pixels from the respective detection circuits along with X-coordinates and end of line bits. The memories are sequentially read up to their end of line bits, and the defect pixel values along with coordinates expanded to include section indicating bits are transferred from the camera to further processing facilities.

The present invention relates to an array of simulated candles, utilizing light bulbs, which allows the user to turn on any selected light bulb merely by pointing a wand close to the light bulb to be turned on. Once turned on the light bulbs are caused to flicker in a manner which simulates very realistically the flickering of candle flames, including the increase and decrease of the illumination of all of the light bulbs (or selected groups of light bulbs if desired) which are observable in an array of candles during random breezes encountered by the candles in a room.

An electronic bingo system for generally enhancing the operation and playing value of the game, by providing such features as flashing the last number called, providing an exciting light display upon designation of a winner, etc. The game is comprised of a ball table including a matrix of numbered switches for closure upon interference by a numbered ball, a plurality of control switches, a general display for individually illuminating one or more numbers corresponding to each numbered switch of the matrix of switches, circuitry at the table for causing a digital display to indicate the number of the numbered switch upon the at least temporary closure of one of the numbered switches, and circuitry for illuminating the corresponding number in the general display upon at least temporary closure of a predetermined one of the control switches.
