    Abstract: A binary valve (40) for use in an anti-lock brake system having an electronic control unit (12) responsive to a wheel speed sensor (14) for optimizing the utilization of pressurized fluid to front (20, 22) and rear (24, 26) wheels during a brake application. The binary valve (40) is responsive to an input signal from the electronic control unit (12) derived by calculating when a complete stop (54) of a vehicle would occur and at approximately five seconds prior to such complete stop (54) decaying the fluid pressure supplied to the front (20, 22) brakes to provide a transition (58) between the rate of deceleration (52) and a delayed complete stop location (58).

    Abstract: An optical illumination system comprising a waveguide (16) that accepts light generated by a diffuse light source (14) and transmits the light via total internal reflection. Attached on one face of the waveguide is an array of microprisms (90), with each microprism (90) having a light input surface (92) parallel to a light output surface (94) and at least two sidewalls (96, 98) tilted at an angle from the direction normal to the surface of the waveguide (16) such that light escapes from the waveguide, reflects off the tilted sidewalls (96, 98) and emerges from the microprism (90) as a spatially directed light source. An array of microlenses (80) may be positioned to accept the output of the microprisms (90) so that the light exiting from the microlenses (80) is a substantially collimated light source. The optical illumination system is advantageous for any application that requires a non diffuse or substantially collimated that is both energy efficient and contained in a low profile assembly.

    Abstract: A gas turbine engine has a low cost combustor liner cooling sytem combining the benefits of high internal heat removal with improved film cooling by employing a large number of strategically positioned, laser-drilled cooling passages (28). Cooling air flows through these specially tailored passages (28) to absorb heat from the liner (20) prior to injection as a protective film on the interior surface. The passages (28) are set in staggered rows on a thickened portion of the liner (20) and have a rough internal heat transfer surface and an exit with a steep injection angle (34B) to evenly distribute the cooling film along the interior surfac of the liner.

    Abstract: A method of attenuating audible sounds generated during a brake application through the engagement of a friction member (10, 30) with a rotating member. The brake is evaluated by modal and frequency response analysis to determine the natural frequencies generated during a brake application and identify the natural frequencies that create audible sounds. The locations on the friction member (10, 30) are identified which are most sensitive to generate audible sounds. Thereafter, portions (12-18, 32-54) of the friction material at the most sensitive locations are removed to change the natural frequency and attenuate the development of audible sounds.

    Abstract: An electromagnetically-excited silicon micromachined vibrating beam accelerometer (40) includes a proof mass or pendulum (44) attached to an outer casing (42) by way of a pair of flexures (46) defining a hinge axis HA. A double-ended tuning fork (DETF) (48) is connected between the proof mass (44) and the casing (42) along an axis generally perpendicular to the hinge axis (HA) defining a sensitive axis SA such that forces applied along the hinge axis HA will cause the DETF (48) to go into either compression or tension. Electromagnetic excitation causes the vibrating beams (52, 54, 102, 104, 106, 108, 134, 136) to vibrate at a resonant frequency when the proof mass (44) is at rest. In response to a force along the sensitive axis SA, the vibrating beams (52, 54, 102, 104, 106, 108, 134, 136) go into either tension or compression resulting in a change in the resonant frequency which, in turn, is used as a measure of the force. The excitation includes a magnetic field B, applied in a direction generally perpendicular to the plane of the DETF (48) and perpendicular to the sensitive axis SA. In order to eliminate the effects of variations in the resistance path of the vibrating beams (52, 54, 102, 104, 106, 108, 134, 136) due to either manufacturing tolerances and temperature, the DETF (48) in accordance with the present invention is formed as a dual-port device with separate conducting paths for the drive circuit and the pick-off circuit. By providing separate conducting paths, the effects of changes in the resistance path of the drive circuit have little effect on the overall performance of the oscillator. Since the beams (52, 54, 102, 104, 106, 108, 134, 136) are separated, the DETFs (48) are configured to provide sufficient mechanical coupling of the beams (52, 54, 102, 104, 106, 108, 134, 136) forming the DETF (48).
