Abstract: A flush-mounted, multi-service floor outlet, gives economic supply of flush-fitting power and electronic jacks, such as Category 5 data jacks, within existing office towers having poured concrete floors, as original equipment, or by restro-fit or in relocating such services, while maintaining effective fire separation between the repective floors of the building. A unitary, longitudinally compartmented cylindrical metal housing is located in penetrating relation through an existing concrete floor, and the power, voice and data connections are routed through the ceiling space of the underlying room, the conduits for which are threaded into a base portion of the housing.  The outlet housing provides a nominal fit within a standard sized hole drilled through the concrete floor to render the installation substantially fireproof. A top flange, and removable bottom flange such as a nut complete the fireproofing and secure the housing in place. The compartment partitions are withdrawable to facilitate installation and servicing.  The substantially planar top face of the outlet fits effectively flush with the usual carpet floor covering.

Abstract: A speech-responsive voice messaging system provides a hierarchically-simple speech user interface (UI) that enables subscribers to specify mailboxes, passwords and the like by spoken word. Results are recognized as good, bad or question- able according to a set of quality thresholds. Based upon the outcome of the quality evaluation, a caller is navigated through speech UI menus. In response to repeated failures of recognition, the system automatically transfers to a DTMF UI. The speech and DTMF UIs overlay each other seamlessly for utilization of desired functions in response to mapping of candidate results.

Abstract: L'invention est un circuit capteur d'images qui utilise une photodiode conjointement avec un mécanisme de transfert de charges. En utilisant une photodiode, au moins une partie de la lumière détectée ne traverse pas une couche de polysilicium et, par conséquent, n'est pas empêchée d'atteindre la zone de détection par le polysilicium. Le circuit de l'invention est constitué de structures facilement disponibles sous la forme de dispositifs CMOS standard. Dans la concrétisation privilégiée de l'invention, les capteurs d'images ont un rendement quantique substantiellement amélioré aux courtes longueurs d'onde par rapport aux capteurs actuels. De plus, ils ont une plus grande uniformité quant au courant d'obscurité, ce qui accroît le rendement.

Title: Wet-on-wet primer with low film build u.v. light protection
Inventor: JACKSON MICHAEL L
IPC: C08J7/046
Filed: 1998-05-27
Granted: 2001-10-30
Abstract: A sprayable, solvent-borne, primer composition for use as a first coat on light-sensitive, automotive plastic parts. The primer serves as a barrier to block ultraviolet light penetration to the underlying substrate and to prevent migration of substrate degradation and by-products up into the topcoat finishes. The primer is a solvent blend of a film-forming crosslinkable polymer resin, a crosslinker for the resin, a catalyst, carbon black pigments surface modified with a polymer dispersant and an organic pigment derivative co-dispersant, crosslinked polymer microgel particles, and U.V. absorbers and optional antioxidants. The surface modification on the carbon black pigments results in higher pigment loadings, which, in turn, imparts U.V. light protection at exceptionally low dry film builds. Furthermore, the microgel particles cause the primer to build in viscosity and set up a gel structure in its uncured state, which allows the primer to be overcoated wet-on-wet with automotive topcoat finishes and cured simultaneously in a single bake without diminishing the topcoat appearance and physical properties. The need for a separate primer bake prior to topcoat application is, therefore, eliminated.

Granted: 2005-08-16
Abstract: A nozzle in a nozzle plate for an inkjet printhead is formed by directing a laser beam at a nozzle plate. Accurate control of the divergence of the beam is achieved by splitting the beam into sub-beams, eac h sub-beam having divergence with an origin lying apart from the point at which the beam is created by splitting, and thereafter recombining the sub-beams. Greater accuracy in the taper and inlet shape of the manufactured nozzle is thereby obtained.
