Title: Control of metallic appearance in automotive cast paint films
Inventor: TRUOG KEITH L
IPC: B29C37/00
Filed: 1996-06-05
Granted: 2003-12-09
Abstract: A thermoplastic and thermoformable pigment-containing metallic automotive paint is solvent cast and dried to form a finished automotive paint coat for a decorative film used in a thermoforming process to form an exterior paint layer on a molded plastic automotive body panel (16). The paint coat (26) contains a pigment uniformly dispersed in a polymeric binder material preferably comprising an alloy of a polyvinylidene fluoride (PVDF) copolymer and an acrylic resin in which the PVDF copolymer is provided as a dispersion in the acrylic resin. Preferably, the dispersed form of the PVDF  copolymer has a maximum particle size less than about 35 microns, and more preferably 20 microns, with a mean particle size range of 6 to 10 microns. The dispersion ratio is preferably from 80 % to 20 % PVDF copolymer and from 20 % to 80 % acrylic resin, respectively, by weight. A low molecular weight form of the PVDF copolymer is preferred and characterized by a melt viscosity of 17,000 to 20,000 poise at 230°C.  Reflective flakes (28) are uniformly dispersed in the polymeric dispersion material and the dispersion form of the PVDF copolymer inhibits parallel orientation of the reflective flakes to produce a more random orientation that achieves a metallic appearance similar to standard spray painted metallic paint coats.

Title: Vehicle headlamp system
Inventor: COUSHAINE CHARLES M
IPC: F21Y101/00
Filed: 1997-12-30
Granted: 2007-06-05
Abstract: A vehicle headlamp system having optical reflector, lamp capsule, and gasket is disclosed. The vehicle headlamp system uses surfaces formed as part of the optical surface yielding located light source. As a result, the light source is more accurately positioned with respect to the reflector, and a more accurate beam pattern is formed. The lamp capsule is assisted in its location by a spring to force the capsule in proper location. The headlamp system no longer uses an O-ring to provide location, but an improved flat resilient gasket provides a sealing and locking force to maintain proper face to face coupling. The preferred lamp capsule uses a cup to shield light reflected from the press seal. The preferred lamp capsule uses a cup, and pedestal system mounting providing five axes of light source positioning. The preferred lamp capsule uses a clip coupling to join the light source holder to the plastic base.

Inventor: WILLIAMS TERRY L
IPC: H04B1/38
Filed: 1994-10-18
Granted: 2001-12-25
Abstract: A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, previously applied to narrowband speech analysis research, for wideband signal processing. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units, which process (e.g. demodulate) respective ones of the digital channel signals and supply processed ones of the digital channel signals at respective output ports for distribution to as attendant voice/data network. On the transmit side, a transmit section contains a plurality of digital signal processors, respectively associated with respective ones of a plurality of incoming (voice/data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.
