Abstract: Projection lens systems for use with cathode ray tube (CRT) projection televisions are provided which have positive first lens units (U1) and negative second lens units (U2) where the negative second lens units are customized in terms of at least one optical property for at least two of the colors of light produced by the CRTs with which the units are used. The at least one optical property is not spectral transmission, although the second lens units can also be customized for spectral transmission. As illustrated in FIGS. 1B-1F and FIGS. 8B-8F, such customization of a non-transmissive property provides an effective and cost effective approach for improving the color performance of CRT projection lens systems. Constructions for the positive first lens unit which improve image contrast and reduce manufacturing costs are also provided.

Abstract: In an active region of an optical-electronic semiconductor device, nitrogen is incorporated in a barrier adjacent a GaNAs-based (e.g., GaInNAs) quantum well to improve device performance at wavelength bands above 1.2 microns. In a specific example embodiment, a mirror or cladding layer is grown over the active region in a manner that removes nitrogen complex otherwise present with Ga—N bonds in the active region. The embodiment can be implemented as one of a number of configurations including vertical cavity surface emitting lasers (VCSEL) and edge emitting lasers.

Abstract: Controller calibration methods for use with sampled getting distributed Bragg reflector SGDBR laser (102) is presented. An exemplary method includes conducting a two-dimensional mirror current scam of each front mirror current setting and back mirror current setting for a sampled grating distributed Bragg reflector SGBDR laser(102) to produce laser setting data corresponding to each front mirror current setting and back mirror current setting to generate a reference optical signal (114) of the SGDBR laser (102). A channel operating point is determined for each channel within the two-dimensional scan data A fix up of the operating point to substantially minimize wavelength and power error can also be performed A two-dimensional control surface is characterized at the channel operating point for each channel. A lookup table for controlling the SGDBR (102) laser is generated from the operating point currents, locker values and two-dimensional control surface data from each channel.

Abstract: A graphics system includes a graphics processor for rendering graphics primitives with a display list. A host processor generates a display list which includes a command format for loading the display list into a register file. The graphics processor includes logic to encode and decode the command register to sequentially load the display list into the register file without a physical reference to the register being loaded. The command register may also be programmed to allow the graphics processor to randomly load the register file thereby shortening the processing of the display list and allowing the display list to be written during a burst cycle mode of bus operation.

Abstract: A cover assembly for concealing an air bag restraint system in a vehicle passenger compartment has an underlying support and air bag door substrate. The door substrate is held in the closed position by flexible tabs that are disposed in a slot at the confronting edge of the support. When the air bag inflates, it engages the door substrate and pushes the tabs out of the slot to release the door substrate. The door substrate then swings open rupturing the covering to provide an opening through the cover assembly for deployment of the air bag.
