A compact pointing device of a novel constitution featuring high operability. A disk-like operation unit 4 is disposed on the PC substrate 8 via an annular resilient stopper 7. Magnets 11, 12, 13 and 14 are arranged on the lower surface of the operation unit 4 along the circumference thereof maintaining an angle of 90 degrees. Hall elements 15, 16, 17 and 18 are arranged on the upper surface of the PC substrate 8 opposed to the magnets 11, 12, 13 and 14. A processing circuit is mounted on the PC...

A pointing device employs a panel mounted at an opening in a keyboard of a computer, such as a portable computer with a hinged display screen. The panel is mounted with freedom to move in two dimensions. A knob projecting from atop the panel has an indicating pushbutton. A sensor mounted adjacent to the panel can produce a motion signal in response to motion of the panel. The panel may be mounted with freedom to rise above the sensor and move in the two dimensions without actuating the sensor. A...

A pointing device includes a resilient substrate having flat upper and lower surfaces, a plurality of strain gages integrally formed on at least one of the upper and lower surfaces of the substrate, and a stick having a base connected to a central portion on the upper surface of the substrate, and a tip end opposite the base and displaceable in an arbitrary direction. The stick extends perpendicularly to the upper surface of the substrate. A displacement direction and a displacement quantity of ...

A system is coupled to a pointing mirror (12) for stabilizing it and its line-of-sight (13) from three-dimensional rotational disturbances (.omega..sub.i, .omega..sub.j, .omega..sub.k) exerted thereon. First and second two-degree-of-freedom dynamically tuned gyroscopes (26, 28) are secured to the mirror and placed respectively on its elevation and azimuth axes (22, 24). The first gyroscope (26) is coupled to electronic apparatus (30) to provide inertial rates (.omega..sub.4 *, .omega..sub.2 *) o...

An improved mirror pointing method and apparatus which stabilizes a mirror relative to the line-of-sight of the input image. The invention includes an outer gimbal pivotally mounted on a pedestal which is in turn attached to a reference frame. An inner gimbal is pivotally mounted on the outer gimbal and the mirror is separately pivotally mounted on the outer gimbal. A linkage is provided between the inner gimbal and the mirror to stabilize the mirror relative to the line-of-sight of the input im...

A remote pointing system which permits the remote positioning of a laser beam in accordance with signals received from a laser beam situated at another location. These signals are derived through the use of an appropriate filter, television camera, pair of counters and modem located at the transmitting location and a telephone receiver, modem, microcomputer, pair of analog to digital converters and suitable beam directing means at the remote or receiving location. By interconnecting the above-me...

When an indicating area in a three-dimensional space is entered from an input unit, an indicating area-object distance determination unit determines the distance between the indicating area and an object in the three-dimensional space on the basis of the coordinates of the indicating area and the representative coordinates of the object, which are stored in an object coordinates memory unit. A color parameter is read out from a display color memory unit in accordance with the determined distance...

Method and apparatus for forming a generally cylindrical point on a tube by first flattening the tube from at least three sides to a polygonal cross section while forming curved sections between the flat sides, and then progressively contracting the tube to bring the curved sections together while buckling the flat sides inwardly into loops that are flattened inside the point. At least three die shoes arranged around a die recess in alternately overlapping relation have flat inner faces with an ...

A pointing device comprises a mouse tablet having a regular repetitive pattern of field sensitive pixels on the surface thereof, and a mouse including coupling elements movable across the mouse tablet, wherein the coupling elements establish position-dependent field coupling with the pixels. Analysis of the coupling yields mouse motion and direction of motion. In one embodiment, the pixels are deployed in rows and columns and a pair of coupling elements are provided for sensing motion and direct...

A mortar joint pointing guide having a mortar supporting plate formed with a front opening defined by an elongated horizontal margin and end flanges presenting margins at right angles to the horizontal margin so that a clear opening frames a horizontal and two vertical joints of a brick for guiding the application of the pointing mortar. The guide has a centrally located handle and a front margin extension for cooperation with the handle to steady the guide in use, and in addition the sides and ...
