Abstract: Embodiments include a loading rack apparatus mountable on a vehicle having a hoist motor, an extendable horizontal trolley to permit a load to be lifted with the hoist, moved horizontally into a vehicle, and lowered. A variety of embodiment trolley drive mechanisms are disclosed including but not limited to a rack-and-pinion means, belt drive means, and a lead screw means. A control means prevents trolley and hoist motor overcurrent. The control means includes a plurality of safety features including a tilt detection means to avoid loading under unsafe conditions and a pressure sensitive switch to halt trolley movement if the trolley contacts an object or person. A DC motor control means provides button control for trolley and hoist motors and emergency cut off. The top surface is shaped to define a surface for items. An arcuate embodiment crossbar member permits more stable positioning of items on the apparatus's topmost surface. A method for safely moving a load is disclosed.

Abstract: A multi-use vehicle mounted loading rack system adapted to safely lift and move loads onto and off of a truck. The system includes a support which rests on bed rails which rest on a truck bed, a horizontal member, a trolley which is reversibly extendable relative to the horizontal member, a hoist mounted on the trolley, and an electrical control system including a tilt sensor and other safety features.

Abstract: Disclosed is a portable computer keyboard capable of operation in three distinct modes: stand-alone mode, automatic mode and a conventional mode. In stand-alone mode, information entered is stored in an on-board memory buffer, and may be edited by using a set of predetermined editing keys in conjunction with a display mounted on the device. In automatic mode, the contents of the on-board memory buffer are transmitted, by a keystroke emulation technique, to an attached host computer via a conventional keyboard connector cable. In the conventional keyboard mode, keystrokes entered are transmitted directly to an attached host computer. The keyboard of the invention may be operated in connection with a plurality of different host computers, and includes host detection and host identification to facilitate operation with such a plurality of different host computers. Also disclosed is a power conservation technique where the device enter a dwell or sleep mode when waiting to process keystrokes.
