摘要： A tape head positioning system for a tape cartridge drive data backup system having a stepper motor with a lead screw connected to the stepper motor and a follower nut threadedly engaging the lead screw. The follower nut has a formed slot for receiving one end of a lever arm. The other end of the lever arm engages in a formed slot a head mounting assembly carrying the tape head and the lever arm is pivoted a first predetermined distance from the first end and a second predetermined distance from the second end. The ratio of the first predetermined distance to the second predetermined distance determines a mechanical advantage for the system thereby causing an inexpensive coarser stepper motor to effectuate fine adjustments of the tape head.

摘要： An interchangeable adapter module allows a circuit board, tape cartridge system, or other add-on device to be readily interfaced with any of a variety of different computer systems. A number of pins extend perpendicularly outward from the device circuit board. An adapter circuit board having a pin connector attached thereto engages these pins to removably secure the adapter module in a plane parallel to the device circuit board. One or more external connectors attached to the adapter circuit board are then plugged into corresponding connectors of the external electronic system. Electrical interface circuitry on the adapter circuit board provides electrical interconnections between a predetermined set of the pins attached to the device, and a predetermined set of the electrical contacts of the external connectors.

摘要： A back support is pivotally oriented to locate a pivot point relative to posterior superior iliac spines of a seated user, such that when an upper portion of the back support contacts the upper torso of the user and moves to a desired angular orientation to balance the upper torso over the pelvic area, the back support transfers support to the posterior superior iliac spines to maintain the pelvic skeletal structure in alignment. A lower portion of the back support angularly contacts, supports and confines gluteal and buttocks tissue of the user independently of the degree of pivotal orientation of the upper portion.
