摘要:
A power sliding door assembly for a motor vehicle comprising a door structure constructed and arranged to be mounted on a motor vehicle for movement between closed and opened positions and a drive assembly mounted on the door structure. The drive assembly includes a rotatable gear engageable with a gear track provided on the vehicle. The rotatable gear is drivable in a one direction to effect movement of the door towards the opened position and drivable in an opposite direction to effect movement of the door structure towards the closed position. A drive shaft is coupled with the drive assembly and is constructed and arranged to rotatably drive the rotatable gear. A reversible motor is mounted on said door structure and is energizable to drive the drive shaft in a first direction to enable the drive shaft to drive the rotatable gear in the one direction, and energizable to drive the drive shaft in a second direction opposite the first direction to enable the drive shaft to drive the rotatable gear in the opposite direction. A clutch assembly is provided that is constructed and arranged to selectively couple the reversible motor with the drive shaft, so that the reversible motor is coupled to the drive shaft when energized to rotate the drive shaft in either of the first and second directions, and so that the reversible motor is de-coupled from the drive shaft to prevent back-driving of the motor when the door structure is manually moved between the opened and closed positions.

A locking device is provided for preventing an outside door handle assembly, having a handle, a stem extending out from the handle, and a counterweight operably connected between the handle and a release rod, from activating the release rod in response to a motor vehicle impact. The locking device includes a catch fixedly secured to the counterweight and engageable with the stem in response to the motor vehicle impact in order to prevent the handle from activating the release rod.
摘要:
Viable biological material is cryogenically preserved (cryopreservation) by preparing the material for freezing, immersing the material in a tank of cooling fluid, and circulating the cooling fluid past the material at a substantially constant predetermined velocity and temperature to freeze the material. A method according to the present invention freezes the biologic material quickly enough to avoid the formation of ice crystals within cell structures (vitrification). The temperature of the cooling fluid is preferably between −20° C. and −30° C., which is warm enough to minimize the formation of stress fractures in cell membranes due to thermal changes. Cells frozen using a method according to the present invention have been shown to have approximately an 80 percent survival rate, which is significantly higher than other cryopreservation methods.
