Abstract: A mechanical arm includes a frame with a distal end and a proximal end opposite the distal end. At least one gear may be rotatably connected to the frame. The gear may include a series of projections along its circumference. A pair of opposing jaw members may extend beyond the distal end of the frame. At least one jaw member may be connected to a corresponding gear. An elongate member may be slidably disposed on the frame. The elongate member may include a row of teeth configured to operatively mesh with the series of projections of the gear and may cause rotation of the gear upon translation of the elongate member. A handle may be disposed on the frame nearer the distal end than the proximal end. The handle may include an actuator connected to the elongate member. The actuator may translate the elongate member upon actuation.

Abstract: A computer controller is described which can be held in and operated by one hand. A thumb operated cursor control is mounted at the top of a pedestal with a grip section extending laterally rearward. Point and click buttons, operated by the user's index and middle fingers, are mounted forward of the pedestal and underneath the grip section. A stabilizing base is attached to the lower end of the pedestal.

Abstract: A tool having a tool shank, includes a tool shank handle fixedly mounted to the tool shank, with respective first and second handle sleeves mounted in coextensive relationship relative to one another about the handle to provide for affording handgrips of adjustable widths to accommodate various individuals.
