Abstract: A safety intravenous catheter assembly and method for use with a needle is comprised of the following. A catheter hub has an axial bore extending through the catheter hub. A needle cover has a first end of the needle cover insertable in the axial bore and a second axial bore extending through the needle cover and co-axial with the axial bore. A continuous circumferential notch extends outwardly in the axial bore of the catheter hub. A notch clip is joined with the needle cover and is positionable to engage the notch of the catheter hub. The notch clip can engage a side of the needle and the notch and locks the catheter hub in engagement with the needle cover when the needle cover is inserted in the axial bore and the needle is inserted in the second axial bore at least adjacent or past a distal portion of the notch clip. Further, the notch clip is maintained adjacent the needle in a range of positions from being in non-forceful contact with the needle to being spaced from the needle.

Abstract: An automatic transmission shift indicator system is provided to electrically indicate the selected gear of an automatic transmission in a motor vehicle. The shift indicator system includes a gear selector, transmission locking plate, a switch and a visual shift indicator. The gear selector connects to a locking plate in the transmission and is manually operative by the vehicle's driver to rotate the locking plate within a range of positions that correlate to each of the selectable transmission gears. The park neutral safety switch is modified to movably engage a stepped cam surface of the locking plate, so that each step corresponds to one of the selectable transmission gears. As the gear selector is shifted from gear to gear, the switch is actuated and thus transmits an electrical signal that is indicative of a selected transmission gear. The visual shift indicator decodes the selected transmission gear based on the resistance value of the electrical signal and displays the selected gear to the driver.
