Granted: 2001-03-01
Abstract: A control device, like a pointing stick, for controlling the positioning, movement and operation of a responsive electrical device, like a cursor on a computer display screen. There is a compact gimbal mounted joystick 10 that has a stick assembly 14; a gimbal assembly 12 having the stick assembly mounted thereon; a sensor 42 and 44 mounted to the gimbal assembly, for generating an output signal indicative of a position of the stick assembly; and a switch 50, positioned below the stick assembly, to be activated when the stick assembly is sufficiently displaced to close the switch. Additionally there is a biasing means 56, positioned about the switch and extending to the gimbal assembly, the biasing means forcing the gimbal assembly into a centering position when not in use. Additionally, there is a retainer 58, positioned between the gimbal assembly and the biasing means, for forcing the biasing means toward the switch when the stick assembly and gimbal assembly have a moving force applied thereto, and for forcing the gimbal assembly and stick assembly into the centering position after the moving force is eliminated. Uniquely, the gimbal assembly, at a location that contacts the retainer, has a shape that minimizes a torque about the first and second yokes when in the centering position and that increases the torque when the first and second yokes are in a non-centering position.

In one embodiment, the inductance of the control winding is substantially constant with a change in current in the control winding. Tn another embodiment, the outer legs are saturated and the center leg is not saturated. Portions of the core connecting the three legs are tapered down from the cross-section of the center leg to the cross-sections of the outer legs.

Title: Camera
Inventor: BITTNER WILFRIED
IPC: G03B17/00
Filed: 2000-09-21
Granted: 2003-03-11
Abstract: The camera of this invention preferably includes a rewind interlock that prevents the double exposure of film. Preferably, the camera of this invention is an advanced photo system (APS) camera that employs APS film. Such APS film may be contained in a film cassette that has a light lock door. The rewind interlock prevents thrusting or pulling a frame of film from the film cassette after that frame of film has been exposed and rewound into the film cassette. This prevents the accidental double exposure of a frame of film. In a preferred embodiment of this invention, the rewind interlock prevents thrusting or pulling film from a film cassette after all of the film has been rewound into the film cassette. Preferably, the rewind interlock prevents the thrusting or removing of exposed film from a film cassette. The rewind interlock does this by preventing the film advancing mechanism from being manipulated in a direction that advances film from the film cassette after the exposed film has been rewound into the film cassette. The rewind interlock may be reset to permit the advancement of film from a film cassette by the removal the film cassette from the camera.
