Abstract: Embodiments are directed in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to stent grafts and methods of positioning and deploying such devices within the body of a patient.

Abstract: A generally rectangular plastic switch housing has locating tabs that position a U-shaped hardened steel grounding strap on the housing so that the strap and housing can be conveniently mounted from the front of a panel in a panel opening that includes relieved and upset portions designed to make electrical contact with serrated segments of the U-shaped strap's legs. The base of the U-shaped strap has an opening with upset edges designed to make electrical contact with the center terminal in the bottom wall of the switch housing.

Abstract: An electrical switch has three terminals, one that is always connected to one side of an LED and in parallel to a resistor. A rocker slides a movable contact to and from an engine OFF or kill position, from and to an engine RUN position. An oil detector circuit uses the engines magneto system to light the LED when the switch is in the RUN position and the engine is rotated. The flashing LED provides a visual indication of low oil in the engine.

Abstract: A rotary internal combustion engine having a stationary casing, and a rotor mounted for rotation about an axis eccentric to the casing forming a crescent shaped compression chamber and a separate crescent shaped expansion chamber. Intake and exhaust ports in the casing respectively communicate with the compression and expansion chambers and first and second vanes angularly spaced apart on the rotor slidably engage the walls of the respective compression and expansion chambers. A rotary transfer valve is provided on the rotor intermediate the first and second vanes to alternately communicate with the compression and expansion chambers. The charge of combustible mixture is ignited while in the transfer valve.
