Granted: 2005-12-20
Abstract: The toothbrush of the present invention comprises an elongated handle having a head attached to one end. The head has a bristle-bearing face having longitudinal perimeter portions adjacent longitudinal edges and at least two perimetric, elastomeric massaging elements alternately arranged with groups of bristle tufts along each of the longitudinal perimeter portions. The brush c an comprise further massaging elements which are not located along the longitudinal perimeter portions though the use of such additional elements i s preferably minimised. The perimetric massaging elements have rotational symmetry through an angle of 120~ or less, preferably being circular. The cross-sectional area proportion of elastomeric massaging elements to bristle s on the brush head is less than 25 %. Alternately there are four or fewer elastomeric massaging elements which are not perimetric massaging elements. A brush with both bristles and gum massaging elements arranged as set out abov e provides both cleaning and gum massaging benefits without creating an undesirable aesthetic impression derived from the use of rubber-like materia ls in the part of the brush head traditionally comprising only bristles.</SDOAB >

Title: Suborbital communications system
Inventor: COX EARL
IPC: H04B7/26
Filed: 2001-04-10
Granted: 2011-07-12
Abstract: This disclosure provides a communications system using a span-loaded flying wing, traveling at relatively slow speeds, that can remain airborne for long periods of time. The communications system uses the airplane as a long term high altitude platform that can serve at least one of a number of potential functions. One function is to link to a ground station using radio wave signals and a satellite using optical signals. Another function is to serve as a relay station between ground communication nodes and individual end-users. Because the aircraft can tightly hold a station, the end-user's antennas do not need to be continuously adjustable. For such a system, a large number of aircraft can be used, with the end-user antennas being configured for a narrow beamwidth so as to allow frequency reuse for different communication links.

Abstract: A method for operating a multi-stage electrical heater comprised of several heating elements. In conventional multi-stage electrical heaters, the resistance value of the individual heating elements scatters. In order that the individual heating elements emit the same power, specifically the required nominal power, despite the scattered resistance values, the voltage on the individual heating elements is separately regulated down to the required nominal power, proceeding from a maximum electrical resistance of the individual heating elements, at which the entire applied operating voltage yields the nominal power of the individual heating elements required for operation.

Title: Arc fault detector immune to dimmer transients and a circuit breaker incorporating the same
Inventor: ZUERCHER JOSEPH CHARLES
IPC: H05B39/09
Filed: 2002-12-18
Granted: 2011-08-09
Abstract: Tripping of a circuit breaker by an arc fault detector is blocked by a disable circuit upon detection of a transient associated with cold turn-on of an incandescent bulb powered by a dimmer. The peak value of pulses generated by the bandpass filter of the arc detector in response to step increases in the ac current is decayed approximately exponentially. The amplitude of each pulse is compared with upper and lower percentage limits of the decaying peak value. If the amplitudes of the pulses remain below the upper threshold for about 3 to 4 half cycles and exceed the lower threshold each half cycle, a dimmer transient is identified and logic is set to block generation of a false arc signal.

Title: Apparatus and method for polarizing polarizable nuclear species
Inventor: HERSMAN F WILLIAM
IPC: B01J19/12
Filed: 2001-07-12
Granted: 2012-12-04
Abstract: The present invention is a polarizing process (10) involving a number of steps. The first step requires moving a flowing mixture of gas (12), the gas at least containing a polarizable nuclear species and vapor of at least one alkali metal, with a transport velocity that is not negligible when compared with the natural velocity of diffusive transport. The second step is propagating laser light in a direction (14), preferably at least partially through a polarizing cell. The next step is directing the flowing gas along a direction generally opposite to the direction of laser light propagation (16).  The next step is containing the flowing gas mixture in the polarizing cell (18). The final step is immersing the polarizing cell in a magnetic field (20). These steps can be initiated in any order, although the flowing gas, the propagating laser and the magnetic field immersion must be concurrently active for polarization to occur.
