Abstract: A nib for a stylus for use with a tablet and stylus computer. The nib provides a desired amount of firmness and friction between the stylus and a writing surface of the tablet and stylus computer. A nib substrate material approximates a desired nib-and-writing-surface firmness and a desired amount of friction between the nib and the writing surface. A secondary material is optionally added to the nib substrate material to alter the amount of friction between the stylus nib and the writing surface.

Abstract: A haptic feedback joystick provides input signals for controlling computer programs in response to a pivotal displacement of a joystick control handle about a plurality of orthogonal axes. Haptic feedback force effects are applied to the joystick control handle about “X” and “Y” axes in response to haptic feedback command signals generated by the computer program. The control handle is mounted on a control handle shaft that is pivotally coupled to a full-gimbal assembly driven by two electric motors to produce the haptic feedback force. The full-gimbal assembly includes an upper and lower gimbal operatively coupled to a corresponding electric motor. One side of each gimbal includes a support shaft mounted in a corresponding bearing a frame, while the opposite sides of each gimbal include two drive pins that couple with a sector gear. Each sector gear is rotatably mounted on the frame and is coupled to the drive shaft of a different one of the electric motors.

Abstract: A processor in a haptic joystick renders force effects that are applied to control handle gripped by a user. A plurality of force effects specified by a host computer to the processor are stored in a random access memory (RAM) that is coupled to the processor. Further, a plurality of force effects are stored in a read only memory (ROM) that is coupled to the processor. The processor employs a scheduler to render the force effects in a specified order, for specified time intervals. The scheduler controls how the force effects are rendered, i.e., sequentially, concatenated, and/or superimposed. A play list employed by the scheduler indicates for each increment of a servo clock when each force effect should be rendered by the processor. The scheduler has a round robin queue that can implement at least five types of effects, including: behavioral, synthesized, wave table, variable parameter, and process list.

Abstract: Apparatus for clamping a device to a work surface. A cam actuated, adjustable clamp provides a connection between the device and the work surface. The clamp includes a handle and a lever pivotally coupled to a housing member; a hand rotated threaded bolt in the end of the lever is used to adjust the position of a shoe to accommodate work surfaces of different thicknesses. The handle and lever pivot about bearings on two rods. Connectors extend between the two rods and they are coupled to the housing member. Cams on the handle ride on a surface of the lever as the handle is moved, applying a force to the lever that controls its position relative the underside of the work surface. The clamp is engaged/disengaged by a single movement (approximately 90 degrees of rotation) of the handle. A spring or linkage may be provided to bias the lever away from the work surface when the clamp is in the open (disengaged) position.

Abstract: A force feedback joystick unit connected to the serial port of a personal computer applies a variety of force effects to the joystick handle in response to commands from the executing personal computer program. Forces are applied to the joystick, which is mounted on a gimbal support for movement in two degrees of freedom, by a pair of drive motors which operate under the control of a digital signal processor (DSP). The DSP is programmed to respond to predetermined commands issued by a program executing on the personal computer to produce basic force effects including a constant force, a spring force proportional to the displacement of the joystick handle from a reference, a damping force proportional to the velocity of the joystick, and a time varying force effect having a selectable waveform, magnitude and period. More complex forces effects are produced by combining the basic effects.
