Title: Pre-biasing technique for a transistor based avalanche circuit
Inventor: DUNNE JEREMY G
IPC: G01S17/10
Filed: 1997-08-21
Granted: 2004-11-23
Abstract: A pre-biasing technique for a transistor based avalanche circuit which improves the initial rate of rise in the current applied through a laser diode or other light emitting device (122) in a laser based distance measurement and ranging instrument and, therefore, the sharpness of the leading edge of the laser pulse produced. Since the timing of the flight time of a laser pulse to a target and back to the ranging instrument is determined with reference to the leading edge of the emitted laser pulse, the inherent precision obtainable is enhanced by the production of a sharper leading edge pulse. The use of the pre-biasing technique disclosed also allows for the substitution of a much cheaper light emitting diode (122) in lieu of a conventional laser diode in an alternative implementation of a light pulsed-based distance measuring and ranging instrument.

Abstract: A connection is provided between two dissimilar elements, such as an aluminum bus and a copper contact. Also provided is a method and apparatus for making the connection. One application is as an anode electrode hanger in an electric smelting furnace. The connection provides a lower resistance electrical connection which can be made while the power to the system is on. In a preferred form the contact is inserted and clamped in the bottom of a chamber in a refractory mold assembly. The chamber opening to the face of the mold assembly is somewhat deeper than the contact. The face of the mold assembly is clamped against the bus, and exothermic weld material is ignited to form a molten metal which drops into the chamber between the contact and bus. The weld metal forms a molecular weld bond with the bus, but only a mechanical interlock with the contact. To enhance the mechanical interlock and to improve the electrical conductivity, the surface area of the contact exposed to the weld metal is significantly increased, and the interlock formed increases both the strength of the connection and its electrical conductivity. The surface area increase is obtained by forming a series of parallel vertical undercut slots in the surface of the contact exposed to the weld metal, and such surface may also be tinned to form a brazed mechanical connection. The connection of the dissimilar metals can be made without shutting off the power and provides improved electrical conductivity.

Granted: 2004-10-26
Abstract: Absorbent devices, and more particularly absorbent devices that are worn interlabially by female wearers for catamenial purposes, incontinence protection, or both, that have an emollient composition on their body-contacting surface are disclosed. The interlabial device has a body contacting surface that is pre-moistened or pre-heated with an emollient to prevent drying of the wearer's labial tissue and to reduce friction of the structure against the wearer's labial tissue. The absorbent device is preferably capable of maintaining contact with the inside surfaces of the wearer's labial majors when worn. The emollient composition comprises a plastic or fluid emollient such as mineral oil, petrolatum and/or polysiloxane an immobilizing agent such as a fatty alcohol or wax to immobilize the emollient on the body-contacting surface of the device, and optionally a hydrophilic surfactant to improve wettability of the coated surface. Because the emollient is substantially immobilized on the surface of the absorbent device, less emollient is required to impart the desired therapeutic or protective emollient coating benefits.

Abstract: A draft sill end casting with a locking center pin is disclosed. The draft sill has an open member with an elongate channel aligned with the central aperture of its center plate. A support shelf is within the elongate channel. A center pin has an upper retainer key supported on the shelf, and the center pin extends through the elongate channel to the exterior of the draft sill. The lower end of the center pin has a slot. When mounted on a truck bolster, a lower retainer key is slid through slots in the bolster walls and through the slot in the lower end of the center pin. The two retainer keys, support shelf and bolster walls lock the center pin in position, limiting axial movement of the center pin and limit rotation of the center pin. Thus, the draft sill and truck bolster are locked together to limit relative vertical and horizontal movement between them. The shelf may include rotation stops to limit rotation of the upper retainer once it is in place. The draft sill includes a key passage so that the upper retainer key and center pin can be removed if desired. In two embodiments, the key passages are through the support shelf and lead to the exterior of the draft sill; in these embodiments, the center pin and retainer key can be removed from the draft sill as a unit. In another embodiment, the key passage is formed as a slot in the interior wall of the draft sill above the support shelf; in this embodiment, the retainer key and center pin must be removed independently of one another.

Abstract: A process for reproducing hand and/or finger lines with a camera works without skin contact with the recording device.  By using linearly or circularly polarized light in the paths of the illuminating and the reproducing light rays it is possible to obtain separate representations of the pattern of the epidermis and the one of the hypodermis. An image of the relief of the skin that is rich in contrast is obtained in this way, on the one hand, and it is possible to acquire information from the deeper disposed layers of the skin already supplied with blood. An algorithm searches the skin patterns of the palm of the hand for line elements of different strengths and directions (vectors). The computed numerical identification contains overall frequencies of vectors as well as amplitudes and phases of frequency components of projections of the vector images of both patterns. The process permits controlling people from a distance, complete protection of the measuring system and enhanced security against fraud.
