Thomas J Quinn: Gyroscopic pointer. Gyration, Albert C Smith, August 8, 1995: US05440326 (425 worldwide citation)

A vertical gyroscope is adapted for use as a pointing device for controlling the position of a cursor on the display of a computer. A motor at the core of the gyroscope is suspended by two pairs of orthogonal gimbals from a hand-held controller device and nominally oriented with its spin axis vertic ...

Pointing apparatus and method provide for control of cursor movement and selection of elements on a computer screen. Gyroscopic elements within the pointing apparatus indicate yaw and pitch movements in free space, and a mouse ball and mouse ball encoders indicate movement on a surface. Data indicat ...

Steven P Hotelling: Shaft angle encoder with rotating off-axis interference pattern. Gyration, Michael L Sherrard, August 11, 1992: US05138154 (209 worldwide citation)

A shaft angle encoder adapted for use in a hand-held gyroscope has a motor at the core of the gyroscope suspended by two pairs of orthogonal gimbals to provide two-degrees-of-freedom for the inner gimbal. Power is provided to the motor through conductive elements in the bearings without limting the ...

Steven P Hotelling, Brian R Land: Gyration, Albert C Fenwick & West Smith, December 16, 1997: US05698784 (191 worldwide citation)

A vibrating gyroscope employs an electromagnetic transducer assembly which excites the vibration of the inertial element and senses its trajectory to provide an indication of movement relative to the plane of vibration of the inertial element. The transducer assembly allows for calibration of the gy ...

John Field, Steven P Hotelling: Optically sensed wire gyroscope apparatus and system, and methods for manufacture and cursor control. Gyration, Albert C Smith, January 14, 1997: US05594169 (51 worldwide citation)

Single and dual wire gyroscopes determine the orientation and attitude of a device using optical sensing of radiation interrupted by current-carrying, vibrating tensioned wires within a magnetic fields. The tensioned wires vibrate between end nodes within the respective magnetic fields to provide bo ...

A user interface for multimedia centers advantageously utilizes hand-held inertial­sensing user input devices (200) to select channels and quickly navigate the dense menus of options. Extensive use of the high resolution and bandwidth of such user input devices is combined with strategies to avoid u ...

Hotelling Steven Porter, Bayer Lex, Land Brian R: Digital electronics on suspended assembly. Gyration, November 22, 2006: EP1723388-A1

A dual-axis rotational rate sensor having two vibratory masses coupled to a restoring element and driven in a resonant counter-phase motion, wherein the two masses vibrate with equal but opposite amplitudes along a single axis. The vibratory structure also accommodates motion of the masses in a plan ...
