Abstract: A data entry system for use with one hand that includes nine primary keys and four secondary keys. The nine primary keys are arranged in three symmetrical rows of three keys each and, thereby, form three symmetrical columns of three keys each. These primary keys are positioned and constructed for operation by the index finger, the middle finger, and the ring finger of a user. Two secondary keys are positioned proximal the primary keys so that when the user's hand is properly positioned on the keypad, the user's thumb is naturally proximal the thumb keys (for right hand use). Likewise, two secondary keys are positioned proximal the primary keys such that when the user's hand is properly positioned on the keypad, the user's pinky finger is naturally proximal the secondary key (for right hand use). For left handed users, the data entry system is also provided with a selector switch which inverts the characteristics of the two sets of secondary keys.

Abstract: A support structure and tool guide for use with circular saws and other hand tools comprising two pairs of parallel, vertically-spaced, horizontally-extending support bars; the upper pair of support bars supporting on rollers a tool support plate which is moveable horizontally along the upper support bars; the lower support bars supporting removable workpiece support members; each workpiece support member including rollers allowing horizontal movement of the workpiece transverse to the upper support bars; the upper support bars vertically adjustable in relation to the lower support bars; and devices for aligning the hand tool longitudinally and transversely in relation to the the support bars.

Abstract: The present invention provides a seat belt handle assembly which allows a vehicle passenger to conveniently grasp a seat and shoulder belt from its retracted position for engagement. The apparatus comprises a clip assembly slidably attached to the shoulder belt with a handle projecting from the clip assembly. The clip assembly and handle are positioned such that the handle extends forward from the seat and shoulder belt to a location beside and slightly in front of the occupant's torso when the seat and shoulder belt is in the retracted position, thereby allowing the occupant to grasp the handle of the seat belt handle assembly and pull the seat and shoulder belt forward parallel to the direction of the occupant without the necessity of reaching behind the plane of the occupant's torso.
