A harness for an upper extremity below-elbow prosthesis. The harness includes a humeral cuff having medial and lateral pivot arms configured to removably attach to the socket of a below-elbow prosthesis. The humeral cuff enables a user to suspend the prosthesis without the need of a shoulder strap/harness or body harness. A cable system is affixed to the pivot arms and includes a wheel coupling the pivot arms to the control arm of a hook of the below-elbow prosthesis, thereby enabling users to operate the hook by simple flexion and extension of their arm.

A portable lighting system comprised of a plug-in lamp and a rechargeable power pack having a single phone jack and two parallel circuits to the battery. When upright, a discharge circuit containing a mercury switch connects the battery to the lamp. When inverted, the discharge circuit is opened and the parallel circuit containing a diode allows current to only pass into the battery from the jack coupled to a battery charger. The system will provide light to table surfaces for commercial use such as restaurants, retirement homes as well as in private homes, such as for swimming pool areas and nurseries.

A system providing for personalized real-time instructions for physical fitness training. A data storage medium stores data comprising a set of instructions for physical fitness training on one or more tracks. A playback device reads the instructions stored on the data storage medium and converts them to an audio signal. An audio speaker connected to the playback device provides the audio signal, comprising the set of instructions, to a user located proximate the speaker.

Rechargeable battery packs for table lighting each contain a 3-element phono jack in their base for engaging a battery recharger phono plug the insertion of which opens the lamp circuit. If a phono plug has short circuited elements, its insertion into a battery pack causes a short circuit of the battery resulting in damage or destruction of the pack. This is prevented by inserting a diode in the circuit to permit current flow in one direction. Also disclosed is a fault locator for locating a shorted plug of many plugs on a charger board.

A truck tire/wheel assembly detection system in which the moving thermal dynamics of a truck are measured before cooling off, by passing over and around contact or non-contact thermometers directed toward the tire/wheel assembly and transmits the approximate temperature of each tire/wheel assembly to a computer which will compares the output data and identifies each abnormally overheated tire/wheel assembly and print out location on rig and other information that may be required. A modem controlled by the computer is used to advise other interested parties of rig condition at this check out point.

A protocol for fiber-optic communication systems, or other communication systems based on transmission of unipolar pulses having wide dynamic range provides for information to be transmitted in packets having a predictable time slot for each transmitter. The receiver for such protocol has a first relatively long RC time constant mode conditioned for reception of data packets whose time of arrival is well predictable and a second relatively short RC time constant mode conditioned for reception of asynchronous randomly received packets. In the relatively long RC time constant mode, each packet includes a preamble having a first clamp interval in which no pulse is transmitted, and a second clamp interval in which a continual pulse is transmitted. A transducer on the receiver translates the packets of pulses into differential electronic signals on first and second outputs. First and second coupling capacitors, receive respective outputs of the transducer and AC couples the signals to respective second terminals of the capacitors. First and second switches connect the second terminals of the respective coupling capacitors to ground during the first and second clamping intervals, respectively, of the preamble. By clamping the outputs of the transducer to ground during the first and second clamping intervals, a DC level for each incoming packet is instantly established independent of the magnitude of the incoming packet. In the asynchronous mode, relatively low impedance discharge paths are established to reduce the time constant of the receiver. An output circuit, connected to the second terminal of each of the first and second coupling capacitors, supplies sequences of digital output signals in response to the differential signals.

A digital phase acquisition circuit includes circuits for detecting an edge of incoming data and a plurality of candidate clock phases, the circuitry further including logic for determining when the data undergoes a predetermined phase transition and at least one candidate phase which undergoes a digitally equivalent transition close in time to the data transition so as to enable the candidate phase to be used for choosing an appropriate clock phase for recovering information representative of the data. The circuit further includes logic for comparing a frequency of the chosen clock pulse and the data and adjusting at least one of these frequencies when a predetermined amount of drift therebetween is detected. The invention allows clock to be recovered within 1 bit time of a predetermined data transition occurring and allows an appropriate clock to be maintained through an entire packet regardless of packet length.

An imitation candle type of table lighting fixture contains one or more rechargeable batteries. While the lamp is in its holder, the battery is continously coupled to the small light bulb. The battery is recharged by removing the candle from the holder and plugging it into a recharging unit having a phone plug extending into a jack centered in the bottom of the candle. The insertion of the plug into the jack opens the light bulb circuit and forms a charging circuit through the rechargeable battery.

A wheel mounted hub containing an electrical generator which is pivotally supported in arms of a yoke. The yoke and generator have an offset center of gravity, tending to give the yoke and generator a pendulum-like behavior within the housing. During wheel rotation, the generator tends to remain along a gravitational line of force, forcing a small wheel associated with the generator to turn against the hub. Around the outer periphery of the yoke, yet within the hub housing, is a circuit board which carries a power utilization circuit, so that the electrical path between the generator and the utilization circuit is very short. The circuit board may carry auxiliary circuits such as a current limiter, a generator disengaging circuit, a daylight deactivating circuit and a circuit for allowing operation regardless of direction of rotation.

Wheel-mounted electrical power generator

A generator assembly characterized by a pair of plates driven in opposite directions, and a pair of generators each engaged with one of the rotating plates. The generators are attached to a generator support bearing supported by a central shaft that is rigidly attached to a first plate and which is rotatably coupled to a second plate. A third plate and a drive gear are used to rotate the second plate in a direction opposite to that of the first plate.

Generator assembly with torque balancing generation

A generator assembly characterized by a hubcap and an elongated arm attached at a first end to a central portion of the hubcap such that it may freely rotate therein. A generator is attached to the second end of the arm which is operative to produce electrical power as the hubcap rotates. Because of the generator's offset position there is a 'step-up' effect of the mechanical power supplied to the generator, thus increasing the electrical power developed by the generator. The elongated arm can also be attached to the wheel lugs of the wheel by a suitable frame, or may be manufactured as an integral part of a wheel or hubcap.

Externally mounted generators for pneumatic wheels

A generator characterized by a circular track attached to the relieved circumferential surface of a wheel, a carriage coupled to the track by rotary bearings, a generator supported by the carriage, and a clutch wheel coupling an armature of the generator to the track. The track, which preferably has a T shaped cross section, has a driving surface which causes the clutch wheel to rotate when there is relative motion between the track and the carriage and/or between the carriage and the air within the tire.
