摘要： A system and method for image acquisition enables selective automated application of color management to color image data generated by an image-capturing device by the device driver for the device. In the image acquisition system, each image-capturing device has properties or operation parameters that can be set to control the operation of the device. During an image acquisition operation, color image data generated by the image-capturing device are transmitted to the device driver. If the operation parameters of the device are set to indicate that color management is to be performed, the device driver calls color management functions provided by the operating system to perform the desired color operation, such as a color space conversion, on the received color image data. The processed color image data are then sent to the image-processing application for further processing or editing.

摘要： A method and system for management of radio frequency coverage over a wide geographic area. A database is created specifying a geographic location for each of a large number of possible communication locations within a wide geographic area. Selected physical parameters are then associated with each communication location including: addresses; site plans; structural drawings; and, actual measured signal strength for multiple entities authorized to transmit at selected frequencies within that geographic area. Thereafter, communication locations may be automatically accessed by specifying either a physical location or by accessing those locations where measured signal strengths fall below a selected level. Once accessed, all stored physical parameters associated with a selected communication location may be displayed, including: photographs of the location, site plans, structural drawings and readiness data.

摘要： The engine output torque of a motor vehicle is a function of the extent to which the throttle valve is open, the further the valve is open, the greater the throttle angle and the greater the output torque. Microprocessor based clutch control is provided to measure the throttle angle, determine the output torque, and automatically engage and disengage the clutch with respect to time. The clutch control also allows manual gear operation and clutch slip control.

摘要： Fluid pressure for engagement of a clutch is controlled by a valve alternating between supply and drain conditions in response to a high frequency electrical square wave signal. The valve produces a low flow pilot pressure signal which controls clutch engagement pressure through a valve incorporating a piston which allows clutch engagement pressure to drain whenever that pressure exceeds pilot pressure.

摘要： Friction clutch release apparatus for a motor vehicle comprises a driver-operable master cylinder, a slave cylinder and a conduit which connects the master outlet to the slave cylinder inlet. A liquid reservoir communicates with the bore of the master cylinder between the piston and the outlet when the piston is retracted and has a vent port. The apparatus is assembled, filled with liquid and bled before being installed on the motor vehicle. The vent port may be closed temporarily for convenience of transport and storage after the apparatus is bled, for example by use of a suitable removable closure device which would be removed after installation of the apparatus on the motor vehicle, or may include a movable wall within the reservoir chamber by which liquid within the chamber is separated from that part of the chamber with which the vent port communicates. The vent port may be closed temporarily by a strip of adhesive tape, a bung or other suitable closure device which can be removed readily, or by a puncturable membrane. The movable wall may be a bellows.

摘要： A fluid pressure servo motor comprises a body having two operatively independent fluid chambers each chamber having therein a piston means movable in response to a fluid pressure differential so as to alter in use a two condition device from one to the other of said two conditions. The two piston means each have a lost motion means connection with the device to allow idle return of the pistons on cessation of the pressure differential. The two chambers and their respective pistons are co-axial and the pistons work in opposition to each other, one piston being fixed to a stirrup which bridges the other piston and acts in use against the two condition device, while allowing said other piston to move independently of the stirrup. Also disclosed is a vehicle door locking system incorporating servo motors as described.

摘要： A ratarder for a power transmission shaft comprises a liquid immersed coupling between the shaft and a drag member, the drag member being normally entrained to rotate with the shaft by viscous drag in the coupling. A dry brake mechanism, having a frictional drag greater than that of the coupling, is provided to restrain the drag member for relative movement to take place in the coupling. In the embodiments shown, the coupling comprises a friction disc pack alternately connected to the shaft and the drag member, the brake mechanism firstly restraining the drag member and subsequently shifting it axially to engage the friction disc pack.The coupling is suitable for use in heavy motor vehicle transmission systems.

摘要： A twin-piston (e.g. tandem) master cylinder is provided for a split braking system having disc brakes on some wheels of a vehicle and drum brakes on others. A delay valve is incorporated in the master cylinder for the supply to the disc brakes, the delay valve having a valve member controlled by one of the master cylinder pistons to initially shut-off the supply of fluid to the disc brakes after the piston has moved a short distance. A plunger moves against a control spring to re-open the supply to the disc brakes above a predetermined pressure.

摘要： A tandem master cylinder for a vehicle split hydraulic braking system which has disc brakes in one half of the system and drum brakes in the other. One of the pistons in the master cylinder is prevented from developing a substantial pressure until a predetermined pressure has been developed by the other piston by virtue of a quantity of fluid trapped in a control chamber by a control piston. First and second valve means control the pressure in the control chamber. The valve means include a plunger which initially moves against a first control spring to allow a valve member to seat and trap the fluid in the control chamber and subsequently moves away from the valve member under an increased pressure in the control chamber against a second control spring to release the trapped fluid.

摘要： A release bearing assembly for a vehicle clutch comprising inner and outer relatively slidable sleeves located around the gearbox shaft. The inner sleeve is coupled to the clutch operating lever and the outer sleeve to the release fork of the clutch. The outer sleeve is in a predetermined position when the clutch is engaged and is moved axially away from that position when the clutch is released. An annular member threadably engages the exterior of the inner sleeve and abutment means act on the annular member during clutch release so that the two sleeves move together. Clamping means hold the annular member against rotation during clutch release. Release means release the clamping means when the clutch is re-engaged so that the annular member can rotate about the inner sleeve to allow the inner sleeve to move axially relative to the outer sleeve when it is at the predetermined position to compensate for any wear of the clutch.
