Abstract: A method of typing to reduce repetitive strain injuries comprises coordinating the movement of all moving parts from the shoulders to the fingers to avoid dissonant movement of any one part, starting with the hand and forearm in a natural profile. Each separately moving part is limited to movement to within its mid-range of motion. For speed, a finger is lifted and the hand is rotated to amplify the elevation. Conversely, lowering of the finger to strike a key involves rotating the hand in a reverse direction. The fingers are simply dropped, aiming at the top of the key to eliminate wasteful downward force and reduce finger-to-keyboard impact. Major movement of the fingers about the keyboard occurs simultaneously with upper and lower arm motion to eliminate stressful finger motions. A mouse manipulation method also employ the hand in a natural profile.
Abstract: A portable angle bender for strip metal. The bender has a shallow U-shaped base having a bending fixture mounted to two upstanding side walls. The bending fixture has two guide members joined at a hinge and pivotally attached to the base on their other ends. One guide member pivots about a fixed axis, while the other may slide relative the base to alter the included angle of the fixture. Each guide member has a slider plate mounted thereunder to form a gap with a top plate to which the central hinge is attached. The gaps are open toward the hinge so as to enable endwise insertion of an angled strip of metal into the fixture. The slider members are constructed of a non-stick material, and the gap is dimensioned to facilitate advancement of the strip through the fixture. A quick-release locking nut is utilized for adjustments to the bending angle, and an indicator is mounted to one of the guide members for registration with a series of angle markings inscribed on the base.

Abstract: A dual-chamber syringe has a plunger within an inner delivery chamber in fluid communication with an ejection port. The deliver chamber is formed within a tubular element axially slidable within a tubular guide. The tubular guide and the syringe outer barrel form an outer reservoir chamber. The outer reservoir chamber is sealed from the delivery chamber while the tubular element is in a first position within the guide. Upon withdrawal of the plunger, frictional contact imparted by the plunger seal causes the tubular element to slide away from sealing engagement with the barrel into a second position within the guide. In the second position of the tubular element, a fluid passageway is opened from the reservoir to the delivery chamber allowing fluid to be drawn into the delivery chamber. A porous seal between the plunger rod and barrel allows air into the reservoir during transfer of fluid to the delivery chamber.
