Abstract:

A connecting device is disclosed for electrically and mechanically linking multiple circuit boards arranged in two perpendicular stacks. The connecting device includes two identical connectors, each with a plurality of outwardly extended electrical socket contacts, and a pair of opposite, electrically insulative shoulders projected outwardly beyond the socket contacts. Electrical pin contacts are recessed into the shoulders. The pair of connectors can be engaged when in facing relation, with one of them rotated 90. degree. relative to the other. As the connectors are moved toward engagement, each shoulder of each connector enters into a nesting relation between the opposed shoulders of the other connector, pre-aligning the opposed pin and socket contacts. The shoulders have inclined edges at their outer faces, to assist in capturing their associated opposed shoulders and guide them, in a self-aligning manner, into the nesting relation. The connectors require a 90. degree.

Abstract:

A thermally adjustable headphone system which integrates thermal members to provide heating and/or cooling comfort to the wearer. The thermally adjustable headphone system generally includes headphones having a pair of ear pieces adapted to be worn on, near, or around the ears of an individual. Each of the ear pieces may include a thermal member which is adapted to heat or cool in response to external stimuli. One embodiment illustrates thermal members which act as thermoelectric coolers in response to an electrical current from a power source. Another embodiment illustrates exciters which, in response to an electrical current from a power source, cause a magnetic field which causes a thermal change in chemical compounds stored within the ear pieces. In either case, the thermal members radiate heat or apply cooling through the ear pieces to heat or cool the individual wearing the headphones.
