摘要： Systems and methods for autostereoscopic display of three-dimensional images include a holographic optical element made by preparing a silver halide gelatin emulsion, coating one side of a glass substrate with the emulsion, holographically recording an eyebox on the coated glass substrate using at least three wavelengths of coherent light combined in a source beam that is divided into a reference beam and object beam with at least one of the reference and object beam passing through a beam shaping device to substantially uniformly illuminate the glass substrate from opposite sides, processing the coated glass substrate, and sealing the coated glass substrate by covering the coated side of the glass substrate with an optical cement and securing to a black glass plate. The element may be mounted in a display and illuminated with at least one projector having optical keystone correction with source wavelengths aligned or matched with the recording wavelengths.

摘要： A pulse width modulated (PWM) valve-based hydraulic control system is disclosed. In one embodiment, a feedback control system includes a controller that receives a pressure command signal and a pressure feedback signal. The controller generates a duty cycle control signal that controls a PWM valve. The PWM valve provides a control pressure Pc to control a load, such as an actuator of an automatic transmission system. A pressure sensor measures the control pressure Pc and provides the pressure feedback signal. In another embodiment, a compensator provides compensation for linear and nonlinear effects in the pressure feedback signal, based at least in part, on other inputs, such as fluid temperature. In other embodiments, a plurality of controllers are provided, and a controller is selected by a switching logic processor, or by phase-in and phase-out filters, based on the pressure feedback signal and other inputs. A re-calibration process for the Pc versus duty cycle response of the PWM valve is also disclosed. The re-calibration method updates the feedback control system processes to maintain performance despite variations due to wear, temperature, and other factors.

摘要： A hydraulic manifold assembly includes a manifold containing a plurality of hydraulic channels that direct fluid to a centralized location and a package disposed at the centralized location to measure fluid pressure at pressure ports corresponding to the hydraulic channels. The manifold assembly directs fluid to the single package rather than scattering fluid outputs to multiple sensor locations, simplifying the overall assembly configuration.

摘要： A method includes energizing a solenoid valve of a hydraulic control system according to a predetermined timing schedule to move a valve member of the solenoid valve. The solenoid valve is operatively connected to the switching component by a fluid control passage, such as a passage in an engine block, to deliver pressurized fluid from a supply passage when the valve member moves to switch the switching component from a first mode to a second mode. An operating parameter of the control system is measured. The operating parameter may be a period of time over which the valve member moves, or a sensed operating parameter of the fluid, such as pressure or temperature. The measured parameter is then compared with a predetermined parameter. Energizing of the solenoid valve is then adjusted based on the difference.

摘要： A fluid level detection system includes a fluid reservoir defining a cavity for holding fluid therein. A fluid level sensor is mounted to the fluid reservoir. The solenoid body defines a first opening establishing fluid communication between an armature chamber and a cavity defined by the reservoir. Travel time of an armature within the armature chamber is thereby affected by fluid level in the reservoir. A controller is operatively connected to the sensor and is operable to receive a sensor signal indicative of travel time from the sensor and formulate a control signal corresponding thereto. A power source is operatively connected to the controller for energizing the coil and the controller. In some embodiments, multiple fluid containing components are connected with one or more controllers. An engine, a transmission, and rear axle differentials on a vehicle may be equipped with sensors to provide fluid level, temperature and viscosity information.

摘要： Systems and methods for creating an autostereoscopic display include a holographic optical element (HOE) recorded using coherent light divided into diverging reference and object beams that illuminate the HOE from opposite sides. The object beam passes through first and second diffusers with one diffuser being a directional diffuser to more uniformly illuminate the HOE. Optic elements may be used to more closely match beam diameters and/or profiles of the recording wavelengths. Baffles may be positioned on opposite sides of the HOE with openings aligned proximate the reference beam and object beam paths, respectively, to reduce stray reflections and provide ambient air flow attenuation or damping. One or more edges of the HOE are masked to reduce or prevent stray light from entering and reflecting within the HOE during recording.
