This invention relates to a mold for making a formed chair arm with passages therein.

Mold for making an arm rest for a chair with a tubular passageway therein

A deformable insert and mounting bracket for pivotally attaching an arm to a chair back frame. The deformable insert has a labyrinth path for a pin on the pivoting shaft of the arm to follow during assembly of the arm to the frame to inhibit unintentional removal of the arm during pivotal operation of the arm. Passageways of the path compressingly engage the pin to hold the arm in any position.

The apparatus and method produce visual sensations by applying low voltages through conductive electrodes to the outside of a person's head, for transmission by natural mechanisms to the nervous system--to entertain or inform a sighted person, or to help a blind person to locate nearby objects. As to entertainment, the apparatus generates various waveshapes, and an operator directs one or more to the electrodes. The operator also manually varies waveshape parameters such as frequency, amplitude, duty cycle and dc bias--or controls them with automatic sweep devices at selected sweep rates. Various wavetrains are combined at the electrodes or in the person's head for more-elaborate effects. The electrode wavetrains or necessary control signals are also received for playback. As to information, the apparatus produces coded patterns or even rough analogs of normal visual scenes. As to aiding the blind, the apparatus responds to a sonar signal by placing phosphenes in the perceived visual field roughly where a normal person would see nearby objects.

Apparatus for generating phosphenes

A method of making a particular type of arm rest for a chair, which arm rest is made from a foamed material. Embedded in the arm rest is a flexible tube for containing a control mechanism for the chair.

Disclosed is a presently preferred embodiment of an electronic competitive player response game apparatus having at least three and preferably four player stations. Each of the disclosed stations is provided with a lamp for designating which one of the stations is 'active,' and with a set of push button switches for permitting a player, when his station is active, to select the next active station by the timely actuation of the proper switch. The disclosed apparatus is also provided with a game start switch for causing the commencement of a game round, and with electronic circuitry for controlling the game's progress.
