Abstract: An aircraft controls simulator, for use with a computer programmed for aircraft flight simulation, having a yoke, a throttle control and a rudder control. A cabinet has a shaft extending therefrom attached to a simulated yoke control. The shaft operates an elevator potentiometer responsive to horizontal movement of the shaft and an aileron control responsive to rotation of the shaft. A throttle knob connected to a second shaft operates a throttle potentiometer. A foot operated potentiometer produces rudder control signals. A cable connects the potentiometers to the computer which utilizes the potentiometer positions to operate the flight simulation program.

Abstract: A device for determining a patient's threshold of pain having a gas-tight member, such as a cylinder, for confining a fixed amount of gas and a two-ended member, such as a rod. A first end of the rod is pressed against the patient's body to apply gradually increasing pressure, and a second end decreases the volume of the fixed amount of gas. Indicia are provided for indicating how much the volume of gas decreases. The device may also be modified to test materials for softness or firmness.
