A device employing a magnetorheological (MR) fluid in combination with a stator and a rotor is disclosed, where the stator includes a magnetic field generator. The rotor has a rotational axis and a rotational degree of freedom with respect to the stator. The stator and rotor define an annular space therebetween and are coupled via the MR fluid disposed within the annular space, and the magnetic field generator is in field communication with the MR fluid at the annular space. The device includes a means for promoting the formation of stationary stripes of MR fluid within the annular space in response to rotation of the rotor.

A computer implemented method is for processing an original digital elevation model (DEM) including data for terrain and a plurality of objects thereon. The method includes generating a lower-resolution DEM from the original DEM, and generating an objects-only DEM based upon a comparison of the lower-resolution DEM and the original DEM. The method further includes reducing noise in the objects-only DEM.

A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The motor is drivingly connected to the first arm such that a rotation of the motor causes rotation of the first arm about its first end and moves the stepping member from a retracted position to an extended position, or vice versa. The stop is located within the range of motion of the second arm such that the second arm bears against the stop when the stepping member is in the extended position. The first and second arms are situated such that the first arm is loaded in compression and the second arm is loaded in tension when the stepping member is in the extended position and a load is placed upon it. In another embodiment, a retractable vehicle step assist comprises a rigid frame, a forward planar linkage pivotably connected to the frame along a forward upper connection width, and a rearward planar linkage pivotably connected to the frame along a rearward upper connection width. The retractable vehicle step further comprises a rigid step member having a stepping deck. The step member is pivotably connected to the forward planar linkage along a forward lower connection width, and is pivotably connected to the rearward planar linkage along a rearward lower connection width and on a side of the forward planar linkage opposite the stepping deck. The stepping deck is substantially wider than any of the forward upper connection width, the rearward upper connection width, the forward lower connection width, and the rearward lower connection width.

A trimaran having a hull and outrigger pontoons on each side of the hull. The pontoon are laterally movable away and towards the hull. Each of the pontoons are secured to the hull by forward and aft link boxes. The link boxes are pivotally mounted to the port side and starboard side of the hull. Each of the link boxes are also pivotally secured to a pontoon. The forward and aft link boxes of each side are connected together by a linkage whereby the forward port side and starboard link boxes are arcuately rotated when the aft port side and starboard link boxes are arcuately rotated.

A starting clutch control includes an engine control state and a slip control state. The engine and slip control states include feedforward and driveline damping control terms. The engine state control may further include an engine speed control term. The slip control state further includes a clutch slip control term. Changes to clutch engagement commands are frozen upon throttle tip-in events.

Mobile hospital liquid sanitation cart for convenient and safe collection and ready transport and disposal of liquid waste from patients. A cuplike receptor on flexible tubing is extended to receive waste liquid and convey it to temporary storage in the cart. Rinse liquid is provided to the receptor to wash down the waste liquid and also is available to wash down the waste storage when at a suitable discharge location, as over a toilet bowl or other drain.
