An illumination device, such as a backlight for electronic display devices, is disclosed. The illumination device includes a viscoelastic lightguide optically coupled to a light source, and a nanovoided polymeric layer is used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic lightguide may be a pressure sensitive adhesive.

A vane pump for an automatic transmission includes a housing which may be spaced from the axis of the transmission input shaft axis and driven by a chain or gear train driven by the torque converter hub or disposed on and about the axis of the transmission input shaft and driven at engine speed. The vane pump includes a pair of port plates which reside on the end faces of a pump body having a cylindrical chamber which receives an eccentrically disposed rotor that is coupled to a stub shaft in an off-axis arrangement. The rotor includes a plurality of radial slots which receive a like plurality of vanes. The outer ends or edges of the vanes are in contact with the wall of the cylindrical chamber and the inner ends or edges are in contact with a pair of vane rings received within recesses in the ends of the rotor. The vanes are thus constrained between the wall of the chamber and the vane rings which positively determine their radial positions as they and the rotor rotate. Suitable inlet (suction) and outlet (pressure) ports in the port plates supply and collect hydraulic fluid to and from the cylindrical chamber. A compression spring biases the port plates and body together. The vane pump according to the present invention is self-priming and achieves high pumping efficiency.

Microreplicated light redirecting films suitable for use in autostereoscopic displays and backlights are made to incorporate at least one nanovoided layer whose interface with another layer forms an embedded structured surface of the light redirecting film. The nanovoided layer includes a polymer binder and optional nanoparticles, and may have a refractive index less than 1.35 or 1.3. The light redirecting films may be adapted for attachment to one or more other components of an autostereoscopic display, such as a display panel and/or a light guide of a backlight.

A backlight suitable for use in an autostereoscopic display includes a light guide and a first and second light source assembly. The light guide has opposed first and second major surfaces, and opposed first and second side surfaces. The first and second light source assemblies are disposed to inject visible light into the light guide through the first and second side surfaces, respectively. Substantially all of the first side surface highly transmits a second light portion out of the light guide into air, the second light portion originating from the second light source assembly, and substantially all of the second side surface highly transmits a first light portion in a corresponding fashion. One or more first non-emitting surfaces of the first light source assembly are disposed at least partially between two light-emitting surfaces of the first light source assembly, and are adapted to substantially absorb visible light to reduce crosstalk.

A method of controlling an automatic shifting power transmission having a fluid coupling device, at least one reaction clutch disposed in series with the fluid coupling device, and an electric machine disposed in series with the fluid coupling device and the at least one reaction clutch includes energizing the electric machine to provide additional torque to the first gear reaction clutch when the automatic shifting power transmission is in a first gear launch maneuver and partially engaging the at least one reaction clutch corresponding to a first gear engagement to effect the first gear launch maneuver when engine load is at or above a predetermined value. The at least one reaction clutch corresponding to the first gear engagement is fully engaged when engine load is below the predetermined value.

A dual drive pump system for rear wheel or front wheel drive automatic transmission in a motor vehicle includes a dual drive pump disposed off-axis of the transmission input shaft axis and driven by a gear train driven by a hub. The dual drive pump is also driven by a gear train driven by an engine starter motor. Torque multiplication through the gear train allows the dual drive pump to have a smaller displacement while still providing the hydraulic pressure needs of the transmission. The dual drive pump may be driven by either an engine or the engine starter motor depending on the operating conditions of the motor vehicle.

A vane pump for an automatic transmission includes a housing which may be spaced from the axis of the transmission input shaft axis and driven by a chain or gear train driven by the torque converter hub or disposed on and about the axis of the transmission input shaft and driven at engine speed. The vane pump includes a pair of port plates which reside on the end faces of a pump body having a cylindrical chamber which receives an eccentrically disposed rotor that is coupled to a stub shaft. The rotor includes two halves that define a central chamber. The rotor also includes a plurality of radial slots which receive a like plurality of vanes. The outer ends of the vanes are in contact with the wall of the cylindrical chamber and the inner ends are in contact with a single vane ring received within the central chamber.

A backlight is disclosed and includes a visible light transmissive body primarily propagating light by TIR with a light input surface and a light output surface and a light guide portion and a light input portion. The light guide portion has a light reflection surface and a light emission surface. The light input portion has opposing side surfaces that are not parallel. One of the opposing surfaces is co-planar with either the light emission surface or the light reflection surface. A light source is disposed adjacent to the light input surface. The light source emits light into the light input portion. A reflective layer is disposed adjacent to or on the opposing side surfaces.
