Abstract: A chin-up/pull-up exercise apparatus is disclosed. The exercise apparatus includes a frame, an overhead assist module, and a chin bar. The chin bar is connected to the frame. The overhead assist module includes a set of pulleys, a harness, and a cable spool connected to a motor. The set of pulleys, which is connected to the frame, is positioned vertically above the chin bar. A cable, which travels on the set of pulleys, is connected to the harness and the cable spool that can be rotated by the motor. The exercise machine enables real, full arm extension pull ups regardless of one's upper body strength with applications for physical therapy; physical exercise training; muscle, tendon, and joint rehabilitation; and upper and lower body strength building.

Abstract: A radio accessory (20) for a personal computing device (50) has a receiver (30) and an interface circuit (32) for receiving and digitizing paging signals modulated on a radio frequency carrier. The paging signals are encoded in accordance with a predetermined protocol such as POCSAG. The personal computing device (50) then decodes the digitized paging signals in accordance with software instructions provided either by the instruction memory (40) in the accessory (20) or on a disk (84). The accessory (20) also has an identification code which validates software from the disk (84) to deter unauthorized use of the accessory (20). The accessory (20) also has a transmitter (28) for sending wireless information.

Abstract: A circuit and a method for adding an 8-bit operand to a 16-bit operand are disclosed such that the number of machine cycles required by a data processor to perform such an addition is reduced. The 8-bit operand and the least significant byte of the 16-bit operand are added together within an 8-bit adder circuit to generate the least significant byte of the result. Simultaneously, the most significant byte of the 16-bit operand is stored in a temporary register and is also input to an increment/decrement network. The adder circuit, after a given delay time, generates a carry signal depending on whether a carry-out was produced by the addition. The carry signal and the sign bit of the 8-bit operand control the mode of operation of the increment/decrement network and determine whether the increment/decrement network or the temporary register will be selected to provide the most significant byte of the result.
