Abstract
Abstract A joystick comprising a control handle within which is located an inclination sensitive potentiometer. The potentiometer includes an elongate resistance element and an electrically conductive liquid wiper. Movement of the potentiometer causes the wiper to flow along the resistance element and to vary the output resistance of the potentiometer.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
164 words
An inclination sensitive type joystick, comprising: (a) a handle controllable by an operator of the joystick, said handle having a convex tilting surface for engaging substantially horizontal surfaces during operation; (b) a first inclination sensitive potentiometer mounted within said handle and having an electrically conductive fluid wiper, an elongate resistance element in wiping relation to the wiper, said fluid and resistance element being located within the potentiometer, and electrical leads operatively connected to the fluid and the resistance element to form a potentiometer circuit; (c) a second inclination sensitive potentiometer mounted within said handle and having an electrically conductive fluid wiper, an elongate resistance element in wiping relation to the wiper, said fluid and resistance element being located within the potentiometer, and electrical leads operatively connected to the fluid and the resistance element to form a potentiometer circuit; and (d) means for attaching said first and second potentiometers to said handle so that displacement of the handle is resolved into corresponding output resistance values.
