摘要： A system for controlling a transmission of a vehicle includes an engine control module that generates a command, while the vehicle is rolling in either a forward or reverse direction, to change a transmission of the vehicle from a reverse drive gear to a forward drive gear. The transmission includes a first clutch, a second clutch, a third clutch, and a fourth clutch. A transmission control module, in response to the command, maintains a first clutch in an engaged state, releases a second clutch and a fourth clutch, with the first clutch in the engaged state and the second clutch and the fourth clutch released, applies a third clutch with a synchronizer to engage the third clutch, and, after the third clutch is engaged, reapplies the fourth clutch to engage the fourth clutch.

摘要： A hydraulic control system for a dual clutch transmission includes a source of pressurized hydraulic fluid, first and second actuator control devices in downstream fluid communication with the source of pressurized hydraulic fluid, and first and second clutch control devices in downstream fluid communication with the source of pressurized hydraulic fluid. A first valve is in downstream fluid communication with the first and second actuator control devices. A second valve is in downstream fluid communication with the first valve, the first clutch control device and the second clutch control device, and the second valve is moveable between two positions by the first and second clutch control devices. Selective activation of combinations of the control devices allows for a pressurized fluid to engage the dual clutch and an actuator in order to shift the transmission into a desired gear ratio.

A third embodiment includes a solenoid pump and a latching solenoid valve both communicating with a hydraulic supply between a variable output solenoid valve and a hydraulic actuator in an automatic transmission which maintains clutch pressure by compensating for leaks in the hydraulic components.

摘要： A dental floss device 1 comprises a handle 2 having a head piece 3 and a disposable holder 4 for a length of dental floss 5. The holder 4 comprises a base portion 20 and a pair of spaced-apart jaws 21 extending from the base and which extend to embrace the head piece 3 of the handle 2 when the holder 4 is in a correct alignment configuration with respect to the handle 2. The device has an interlock which ensures that the holder 4 can be interengaged with the head piece 3 only when the holder 4 is correctly aligned with the head piece 3. The interlock comprises a head interlock part provided by interlock grooves 10 and a holder interlock part provided by corresponding interlock tongues 11. There are two interlock grooves 10 and corresponding interlock tongues 11 which slidably interengage when the holder 4 is correctly aligned with the head piece 3. If the holder 4 is turned so that it is not correctly aligned with the head piece 3, the interlock tongues 11 of the holder 4 prevent engagement of the holder 4 with the head piece 3. Thus there is no risk that a user will incorrectly align and engage the dental floss holder with the head piece 3.

摘要： A high efficiency hydraulic control system for a dual clutch transmission includes one or two hydraulic pumps. In a first embodiment, a single hydraulic pump provides pressurized hydraulic fluid to a pressure control valve, filter and accumulator. A first pair of variable feed solenoid valves independently and mutually exclusively provide hydraulic fluid to a respective pair of main or input clutch actuators. A second pair of variable feed solenoid valves provide hydraulic fluid to a pair of inlet ports of a first spool or logic valve. The position of the spool of the first logic valve is controlled by an on-off solenoid valve. A first pair of outlet ports of the first logic valve selectively provide hydraulic fluid to a first three area piston which selects two gear or speed ratios, for example, reverse and third gear. A second pair of outlet ports of the first logic valve selectively provide hydraulic fluid to a pair of inlet ports of a second spool or logic valve. The position of the spool of the second logic valve is controlled by hydraulic fluid from the input clutch circuits. A first pair of ports of the second logic valve selectively provide hydraulic fluid to a second three area piston which selects two other gear or speed ratios, for example, first and fifth gears and a second pair of ports of the second logic valve selectively provide hydraulic fluid to a third three area piston which selects two additional gear or speed ratios, for example, second and fourth gears.
