Abstract: In some embodiments, a vehicle may include a frame having longitudinal axis. The vehicle may include a steering assembly having a steering input and at least one wheel. The steering assembly may be coupled to the frame and configured to steer the vehicle based on input from a steering input. The vehicle may include a first drive wheel and a second drive wheel. The vehicle may include a steering position sensor configured to detect steering input including a position of the steering input and at least one of i) a rate of change of position of steering input and ii) steering position time. The vehicle may include at least one controller configured to process a signal from the steering position sensor and, in response to the processed signal, drive the first drive wheel and the second drive wheel, the first drive wheel being driven independent of the second drive wheel.

Abstract: A motorized vehicle may include a frame, a drive wheel coupled to the frame, a motor operatively coupled to the drive wheel, and an anti-tip assembly including a first anti-tip wheel. The anti-tip assembly may have a first configuration wherein the first anti-tip wheel is both pivotable about a pivot axis relative to the frame and translatable along a sliding axis.

Abstract: A pool jet fitting can include an insert housing defining an insert body, a housing channel, and a base disposed within the housing channel. The base can include an outer sidewall that defines an internal chamber. The fitting has a valve disposed within the internal chamber. The valve includes a valve body, a valve channel that extends into the valve body along the first direction, and a valve opening that extends through the valve body and into the valve channel along a second direction that is angularly offset with respect to the first direction. The valve is movable between a first position whereby the valve opening has a first area through which the water flow moves and a second position whereby the valve opening has a second area through which the water flow moves that is greater than the first area.

Abstract: An articulating leg rest is provided having a first member pivotally connected to a base frame. The base frame may be either connected to or part of a wheelchair frame. A second member is telescopically received by the first member. A drive system includes a motor-driven lead screw. First and second housings each have internally threaded portions engaged with the lead screw. A link connects the first housing to the base frame. The second housing engages the second member. Rotation of the lead screw advances the first housing along the lead screw, moving the link and causing the first and second members to rotate relative to the base frame. Rotation of the lead screw also advances the second housing along the lead screw, causing the second housing to linearly translate the second member relative to the first member.

Abstract: A lift mechanism for a wheelchair includes a parallelogram linkage and an actuator for moving the linkage between a retracted position and an extended position to raise and lower a chair. One link of the linkage is slidingly engaged with a rail member. Movement of the linkage is constrained by another link such that as the chair is raised and lowered, the longitudinal position of an occupant's center of gravity relative to the wheelchair frame is substantially maintained. The lift mechanism may be combined with a tilt actuator to allow rotation of the chair. A chair tilt mechanism is also provided having a tilt actuator, a first link slidingly engaged with a rail member and a second link constraining movement of the first link. The tilt mechanism is capable of tilting the chair while substantially maintaining the longitudinal position of the occupant's center of gravity.
