  • Patent number: 9327733
    Abstract: A method of controlling a clutch-to-clutch power-on upshift of a transmission includes defining a possible engine torque as a latched possible engine torque value. An on-coming clutch torque phase target value is defined as a latched on-coming clutch torque value, and held constant until a final ramp. A commanded engine torque is reduced and maintained to a maximum torque reduction value until a shift completion ratio is achieved. The commanded engine torque is increased until the commanded engine torque is equal to a restore ramp target value. Both the on-coming clutch torque and the commanded engine torque are simultaneously increased at a final ramp rate, such that the increase in the on-coming clutch torque parallels the increase in the commanded engine torque, until an actual engine torque is substantially equal to the possible engine torque, to complete the shift.

  • Publication number: 20140026988
    Abstract: A hydraulic control system for a transmission includes a sump tank, a front cover, a wall, and a flow control valve. The sump tank is attached to a bottom end of the transmission. The front cover includes an overflow tube and a hydraulic fluid input. The wall hydraulically separates the sump tank and the front cover. The flow control valve is disposed in the wall between the sump tank and front cover. The flow control valve is open when the transmission is going through an extreme maneuver and requires a greater amount of hydraulic fluid in the sump tank and the flow control valve is closed during normal transmission operation.

  • Patent number: 7360895
    Abstract: An ocular fundus imager automatically aligns fundus illuminating rays to enter the pupil and to prevent corneal reflections from obscuring the fundus image produced. Focusing the produced fundus image is automatically performed using a pair of video sensors and is based upon the fundus image itself. A head restraint is used to reduce the gross alignment between the optical system and the patient's pupil.

  • Patent number: 6015444
    Abstract: An apparatus and system for venting a transmission (10) is disclosed which provides a transmission breather (12) which allows pressure equalization between the interior and exterior of the transmission while reducing or eliminating fluid expulsion from the transmission. The breather includes a standpipe (18), a bowl (20) having a first end (70) secured to the standpipe and at least one aperture (80), a shroud (22) secured to the standpipe, and a filter (90) disposed between the bowl and the standpipe. The standpipe has a first end (30), a second end (32) and an intermediate portion (34) extending axially between the first and second ends. The second end of the standpipe has at least one surface (46) for transmitting torque to the standpipe to enable the breather to be top drivable to facilitate installation and removal of the breather with the transmission. The intermediate portion has an axially extending central passage (60) and at least one radially extending passage (64).
