Abstract: A preferred embodiment of a lift and carrier assembly for a personal-transportation vehicle includes a first column, a second column telescopically disposed within the first column, a platform assembly pivotally coupled to the second column for supporting the personal-transportation vehicle, and a motor mounted on the first column and coupled to the second column so that the motor can lift the second column and the platform assembly, and a latch. The latch is movable between a first position, and a second position wherein the latch engages a pin mounted on the second column when the second column and the platform assembly are in a second position thereby securing the second column and the platform assembly in the second position.

Abstract: Embodiments of seating systems for motor vehicles facilitate two-dimensional movement of a seat in a horizontal plane. The seating systems can also facilitate vertical movement of the seat. The seating systems are motorized, and can be automatically controlled so that minimal movement and effort are required on the part of the user to enter and exit the vehicle.

Abstract: An adjustable keyboard support is disclosed constituted by a rear housing that pivotally supports one end of a parallel link mechanism. A front housing is carried by the other end of the parallel link mechanism, and pivotally supports a keyboard mounting plate. The parallel link mechanism permits upward and downward movement of the keyboard mounting plate without change in the tilt of that plate. A gas cylinder mechanism coupled to the front housing changes the vertical position of the same, and a slide plate adjustment mechanism provides forward and backward movement of the keyboard mounting plate.

Abstract: An arm extends from a support assembly which may be clamped to the edge of a desk and the angle of the arm relative to the support assembly is adjusted by turning a knob.The outer end of the arm has a swivel connection to a small table or other device. The swivel connection includes a ball and a post extending from the ball. The ball is adjustably clamped between a rim of a hole in the arm and a rim of a hole of an adjustable lever means. The lever means is released and tightened by a knob.
