  • Patent number: 9346345
    Abstract: A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is opened to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

  • Patent number: 8919842
    Abstract: A robotic system includes a tendon-driven end effector, a linear actuator, a flexible tendon, and a plate assembly. The linear actuator assembly has a servo motor and a drive mechanism, the latter of which translates linearly with respect to a drive axis of the servo motor in response to output torque from the servo motor. The tendon connects to the end effector and drive mechanism. The plate assembly is disposed between the linear actuator assembly and the tendon-driven end effector and includes first and second plates. The first plate has a first side that defines a boss with a center opening. The second plate defines an arcuate through-slot having tendon guide channels. The first plate defines a through passage for the tendon between the center opening and a second side of the first plate. A looped end of the flexible tendon is received within the tendon guide channels.

  • Patent number: 8056427
    Abstract: An adjustable head tool (AHT) is configured for positioning a free motion headform (FMH) having a regulated FMH backoff requirement prior to an impact between the FMH and a target surface having a target point. The AHT has a built-in or a variable backoff angle relative to the position of the target point, and includes a cranial portion and an adjustable facial template. The cranial portion encloses a linkage assembly, and the facial template has one or more facial features. A rotary dial translates the facial template with respect to the cranial portion to maintain the regulated FMH backoff requirement. The cranial portion includes a forehead impact zone having a first set of demarcations, and the rotary dial has a second set of demarcations corresponding to the first set of demarcations. The dial is set so the second set of demarcations matches the first set during positioning of the AHT.

  • Patent number: 8056690
    Abstract: A transmission includes a selectable one-way clutch (SOWC) assembly. The SOWC assembly includes a rotatable pocket plate, a rotatable slide plate, and an annular piston having a ramped surface feature. The piston, which can be hydraulically actuated, moves axially toward the pocket plate when applied, and axially away from the pocket plate when released, to thereby select between two torque holding or operating modes of the SOWC assembly. The ramped surface feature of the piston engages an axial knob portion of the slide plate when the piston is applied to select to one operating mode, thus rotating the slide plate in one direction. A return spring moves the piston away from the pocket plate when the other operating mode is selected, and the slide plate is rotated via a spring in another direction. A guide pin maintains a relative position of the piston and the slide plate.

  • Patent number: 7992695
    Abstract: A selectable one-way clutch (SOWC) assembly uses hydraulic-actuation to select operating modes within a rotating housing. Two races of the SOWC assembly can rotate at disparate speeds, i.e., one race is not grounded prior to actuation. The SOWC assembly has a pair of races keyed to different housings and hubs. The housing and hub can be attached to different elements of a gear train, for example, which can be rotating during the various gear states. A hydraulic actuator or multiple actuators can be keyed to the housing, with axial motion of the actuator or actuators selecting a state or operating mode of the SOWC assembly. The actuator has axially-extending tabs that engage radially-extending fingers of the selector plate, thus rotating the selector plate in different directions when applied or released. Multiple actuators can be used in conjunction with multiple selector plates to provide additional SOWC operating modes.

  • Patent number: 7146724
    Abstract: This invention provides a method of assembling a modular internal combustion engine. The modular engine includes a cast crankcase having an open top and a closed bottom, a mid-plate, and an extruded cylinder bore block. A pre-assembled crankshaft with bearings, connecting rods, and pistons with piston rings are all placed through the open top crankcase. The mid-plate partially houses the assembled components over top the crankcase as the connecting rods and pistons extend through and above. Next, the piston rings are simultaneously compressed and the cylinder block is located over the pistons. The pistons with piston rings are inserted into cylinder bores through the bottom surface of the cylinder block and the assembly is completed. This method is performed with the help of a fixture for compressing and positioning the piston rings.
