Abstract: An electrical power source is described. The electrical power source derives input power from a compressed gas which is fed into a transducer, generating electrical power. The compressed gas may be delivered to the unit by several means including manual pumps, thermal, chemical, or ammunition based sources, or connection to pressurized canisters. Optional power converting and feedback circuits and pneumatic valves serve to convert the raw output power into useful AC and DC output voltages, and to match the rate of power delivery to the applied electrical load.

Abstract: There is therefore provided, in accordance with a preferred embodiment of the present invention, a robotic system for systematically moving about an area to be covered. The system includes at least one boundary marker (48) located along the outer edge of the area to be covered, a robot (40) with a navigation system (41) and a sensor unit (43). The navigator system (41) navigates the robot (40) in generally straight, parallel lines from an initial location and turns the robot (40) when the robot (40) encounters one of the boundary markers (48), thereby to systematically move about the area to be covered. The sensor unit (43) senses proximity to one of the at least one boundary marker (48).

Abstract: A hair accessory is described which includes an elongated clip having at least two members, each having at least a user grasping portion, a hair engaging portion, and a transition portion therebetween. The hair engaging portions are configured to be adjacent one another along a longitudinal axis for substantially their entire length. The hair accessory further includes a plurality of hair segments attached to the elongated clip between the user grasping portion and the hair engaging portion. A method for fabricating the hair accessory is also described.

Abstract: An Internet voting system is provided with security against malicious software by using a bootable CD ROM to boot voter client machines for use in elections.

Abstract: An electrical conductor and a gas-filled layer are located at or near the surface of an object being deiced. The conductor carries an AC voltage that generates an alternating electric field in the gas-filled layer. A conductive layer increases the electric field strength in the gas-filled layer between the electrical conductor and the conductive layer. The alternating electric field causes electric breakdown of gas and plasma-formation in the gas-filled layer. The plasma absorbs energy released during electric discharge through the plasma, which heats ice, causing it to melt. The alternating electric field typically has a field strength in a range of about from 1 to 100 kV/cm. The AC voltage typically has an amplitude in a range of about from 10 kV to 1300 kV, and a frequency in a range of about from 50 Hz to 1 MHz. The gas-filled layer includes a plasma-forming gas selected from, among others, air, nitrogen and argon.

Abstract: An autonomous robot is designed for docking in a docking station. The autonomous robot is configured such that it will locate the docking station and dock therein, before its battery power is exhausted. The docking is such that the autonomous robot is automatically charged, such that its batteries will be fully powered for the subsequent operation.

Abstract: A screen printing manual repetition system semi-automates use of a screen with a manual printing press. The screen has a screen frame and a screen mesh. The manual repetition system (MRS) has an MRS frame mountable to the screen frame, a track system, and a height adjustor configured to adjust the height of the track system relative to the MRS frame. A squeegee has a squeegee frame with a blade, guide members configured to guide the squeegee through the track system, and an angle adjustor configured to adjust the angle of the blade relative to the screen mesh during operation.

Abstract: The invention provides a dual thermometer system for the measurement and display of temperature data taken at two separate locations within an oven. In one aspect, the invention provides an elongated probe connected with a flexible electronic cable. The probe houses two temperature sensors—one for sensing internal food temperature, one for sensing inside oven air temperature. The sensors are space apart within the probe such that the one sensor can be positioned substantially within a food item and the other sensor can positioned substantially outside of the food item and within the oven. Signals from the sensors are relayed from the probe and through the cable; external electronics may attach to the cable to acquire the signals and display associated temperatures. In another aspect, signals from temperature sensors are relayed from the probe and through the cable to a first wireless termination.

Abstract: A trailer tongue extension assembly that includes a tubular trailer tongue, a removable extension, a first electrical connector disposed within the trailer tongue and a second electrical connector disposed within the removable extension. The first and second electrical connectors engage and disengage as the removable extension is installed or removed from the trailer tongue. A tongue pin is inserted either through registered holes in the tongue and the installed extension, or through aligned holes in the trailer tongue. A lock assembly secures the pin in the holes to, respectively, lock the extension on the trailer tongue or prevent the extension from being installed in the trailer tongue. Opposite ends of a lanyard or elastic member are attached to the pin and the trailer tongue, respectively, and resist the removal of the pin from the aligned holes.

Abstract: Pathological binaural phase time delay (BPTD) asynchrony is measured at a variety of frequencies and to speech stimuli to develop a BPTD profile for a subject. Then a corrective device (600, 1000) is designed to apply clinical BPTD to compensate for the subject's pathological BPTD. An electronic device (500) is used to measure the subject's ability to comprehend words at a variety of relative time delays between ears to estimate the ideal overall relative time delay. The optimal relative phase shift at a variety of frequencies is also measured. An electronic device (600) may be used to correct the pathological BPTD by delaying sound in different frequency bands differently to the target ear, according to the BPTD profile, or a passive filtered earplug (1000) may be used to correct smaller amounts of BPTD.
