Abstract:
A head up display (HUD) has multiple light sources of varying intensities for projecting a high quality image under various lighting conditions. The light sources provide illumination through an electronic display (e.g. an AMLCD) in the HUD. A high brightness light source illuminates the electronic display during bright or day light conditions. A low brightness light source illuminates the electronic display during night or low light conditions. Both light sources illuminate the electronic display during intermediate lighting conditions. A light panel conducts and diffuses light from the light sources to illuminate the rear of the electronic display. An optional light mixer reduces uneven lighting of the high brightness light source. In operation, the intensities of the light sources are controlled as a function of ambient lighting conditions to optimize the projected image quality.
Abstract:
The problem of directing a bullet end of a brake cable, which may have become curved during storage, into seated engagement with a bullet retention slot in a brake apparatus is reduced through the use of a spring affixed to the brake means for guiding the bullet end of the brake cable into seated engagement with the bullet retention slot, as the bullet end is inserted into the brake assembly along an installation path. The spring may also be utilized for retaining the bullet end in seated engagement with the bullet retention slot after installation of the cable.
Abstract:
An accumulator-dehydrator assembly for use in an air conditioning system including an evaporator and a compressor. The accumulator-dehydrator assembly also includes a canister with an upper portion, an inlet, an outlet and a delivery tube with a first tube end positioned in the upper portion of the canister and a second tube end connected to the outlet. A baffle is disposed within the canister that includes a first end connected to the canister and a second end positioned to define a partition between the first tube end of the delivery tube and the inlet. The purpose of the baffle is to reduce pulsations that result from pressure fluctuations in the air-conditioning system.
Abstract:
A master cylinder for vehicle braking systems includes a housing having a central cavity, at least one fluid supply inlet port, at least one pressure outlet port, and a flange at one end thereof. A piston actuation mechanism within the central cavity is moveable between a first position wherein the central cavity is in fluid communication with the fluid supply inlet and a second position where the central cavity is in fluid communication with the pressure outlet. A cup-shaped end cap is fastened to the housing flange in a fluid sealing relationship wherein the cup-shaped end cap receives at least a portion of the piston actuating mechanism therein and further retains the piston actuation mechanism in an operational configuration within the housing.
Abstract:
A combined drive circuit for a split brake system of a motor vehicle has a switched reluctance motor and a brush motor. The switched reluctance motor has multiple phase windings. The combined drive circuit includes a DC power source with first and second supply buses. A SR motor driver supplies current to the switched reluctance motor. The SR motor driver has a first capacitor coupled to the phase windings for storing energy from the phase windings and a second capacitor coupled to the first capacitor and a third supply bus, thereby developing a third supply bus voltage across the second capacitor. A brush motor driver is coupled to the first and second capacitor. The SR motor driver is adapted to supply current to the brush motor. The brush motor driver has a first switching element and a second switching element coupled to the brush motor.
Abstract:
A gear reduction mechanism includes a gearbox housing, a first gear having a first axis of rotation about a first shaft and the second gear having a second axis of rotation about a second shaft. The first and second gears are rotatably mounted in a gearbox housing so that the first and second gears mesh with each other such that the first axis of the first gear is substantially perpendicular to the second axis of the second gear. The gear isolator assembly is preferably disposed within the gearbox housing about the second gear for reducing noise generated between the first and second gears during operation of the mechanism.
Abstract:
A method and device for controlling an actuator in response to an input signal is provided The device detects actuator position, calculates a force applied to the actuator as a function of the detected position using a predetermined formula, and responsively produces a force feedback signal. The device receives the input signal and the force feedback signal and responsively delivers to the actuator a control signal.
Abstract:
An electrical connector includes a connector housing having a housing frame and a housing core. A housing core can be inserted in a housing frame. The housing core includes a latch protruding from the outer wall of the housing core and the housing frame includes locking means. The housing frame includes locking means. The locking means includes first and second guiding ramps. The first guiding ramp is configured to guide the latch upon insertion parallel to the extension direction of the interior wall of the housing frame onto the second guiding ramp. The second guiding ramp is configured to deflect the latch inwardly towards the interior of the housing frame.
Abstract:
An illustrative example embodiment of a detector device includes a sensor portion that is configured to at least emit or receive a first type of radiation. A cover near the sensor portion is transparent to the first type of radiation to allow the first type of radiation to pass through the cover. A radiation source emits a second, different type of radiation. A plurality of reflecting surfaces are transparent to the first type of radiation and at least partially opaque to the second type of radiation to at least partially reflect the second type of radiation into the cover to increase a temperature of at least a portion of the cover.
Abstract:
A driver-alert system for an automated vehicle includes a display, and attention-detector, a hazard-detector, and a controller. The display is viewable by an operator of a host-vehicle. The attention-detector indicates when an operator is attentive to the display. The hazard-detector indicates when a hazard is present proximate to a travel-path of the host-vehicle. The controller is in communication with the attention-detector, the display, and the hazard-detector. The controller operates the display to warn the operator of the hazard only when the attention-detector indicates that the operator is attentive to the display.
