Abstract: An input device apparatus for providing coordinate data indicative of the motion of an object to a computing apparatus, includes an elongated member translatable along and rotatable about a longitudinal axis, a swing arm attached to the object and to the elongated member such that movement of the object results in corresponding movement of the elongated member, and an engagement surface for engaging an input device of the computing apparatus.

Abstract: An apparatus for use with a telephone including, in one embodiment, a detector for detecting when the telephone is in an off-hook condition and disconnect circuit for eliminating the off-hook condition when the off-hook condition is caused by the telephone so that phone calls may be received by the line. An alarm responsive to the detector produces a warning of the off-hook condition if another phone on the line is off hook.

Abstract: An electronic game that includes a main body that consists of four panels assembled to form a four-sided pyramid having four vertexes. Each vertex serves as a node for supporting a light which may illuminate a plurality of different colors. Digital circuitry defines a color state vector at each node by illuminating one or none of the colors. Control circuitry connected to the digital circuitry is used for altering the color state of at least one of the lights as the tetrahedron is rotated. In one game, the color of the node brought to the top position changes in the color change pattern established by the color state vector. A player rotates the tetrahedron in an effort to figure out the pattern of color changes. Once the pattern is deciphered, the player makes additional rotations to achieve an object of the game such as having each vertex of the tetrahedron lighted the same color.
