Abstract: An amusement apparatus is constructed to be hand-held and includes a display of binary indicators on a playing surface. A sequence of a preselected number of pulses actuates the indicators. The number of pulses varies among the indicators until ultimately, one of the indicators remains actuated.

Abstract: A light signalling device is provided for use with bicycles and includes a housing and a cover mounted on the housing. The cover includes a plurality of light penetrable portions. Light emitting lamps are mounted in the housing for separately illuminating each light penetrable portion. A multi-positionable switch is connected for controlling illumination of the light penetrable portions in various arrays. The cover further includes at least two light penetrable materials. One of the materials being relatively more light penetrable than the other. A lamp retaining member is provided in the housing for electrically interconnecting the ground portion of each lamp with the ground portion of a power source also provided in the housing.

Abstract: An electronic random selection device includes integrated circuits connected to receive a signal from a power source, to generate a first oscillating signal when an associated switch is in a first position and to generate a second oscillating signal, slower than the first oscillating signal, when the switch is in a second position. A plurality of light emitting diodes are sequentially illuminated by the first and second oscillating signals and due to the effect of an interconnected time delay circuit, when the switch is in the second position, the second oscillating signal is ultimately induced to illuminate only one of the diodes. The selection device can be applied to an amusement display such as a playing board having a predetermined array of light penetrable openings formed therein and the light emitting diodes positioned adjacent the openings.
