A wrist watch having a cursor ring rotatably mounted thereon, said cursor being formed with a first laterally projecting portion having a cursor line thereon for setting scales on said watch, and a second projecting portion for manual engagement for the selective rotation and positioning of the cursor ring. A bezel having graduations on its surface may be rotatably mounted relative to a fixed graduated circle on said watch with the first projecting portion of the cursor ring in overlapping relat...

A radar, such as a track-while-scan radar, which is provided with early and late tracking gates interconnected with cursors, blanks out the electronic cursors presentation within the gate region of the display and, instead, modulates the intensity of targets within the tracking gates so that the more closely the cursors are positioned on the center of the target, the higher the intensity of the video in the vicinity of the cursors.

A method of indicating to a user of a terminal which includes a display, of the occurrence of a function which can be implemented on the terminal, comprising displaying a cursor on the display which cursor is moveable by the user and which has a form and position on the display which is related to a program currently being used by the user and which is unrelated to the function, and changing the form of the moveable cursor at the position to one which relates to the function upon occurrence of t...

In a cursor tracking system (FIG. 11), a pointing device includes a plurality of force sensors (304), optionally integrated with a keyswitch on a computer keyboard. The force sensors detect lateral and vertical forces applied to the keycap (300) by a user (302) for cursor control. Raw force data is acquired by A/D apparatus (306) and transmitted (310,312) to a host processor. Driver level software in the host linearizes the raw force values (316, FIG. 12D) to compensate for anomolies and nonline...

A microfilm reader includes a vertical rectangular projection screen surrounded by a rectangular frame. A cursor mechanism is separably provided which includes a vertical rail extending along a side edge of the screen between the frame top and bottom legs and slidably frictionally engaging a support member to which a cursor member is swingably mounted for angular adjustment in a plane parallel to the screen. The cursor member is releasably frictionally retained in its preset angular position and...

A cursor for taking position signals from a grid is includes a coil through which inductive coupling with the grid is established. Because inductive coupling is employed, there need be no physical contact between the cursor and the grid. The cursor is configured so that the effects of orientation changes of the sensor parallel to the plane of the grid are eliminated and the effects of orientation changes normal to the plane of the grid are minimized. Furthermore, the cursor includes a low reluct...

A telautograph system allows a user at one location to write on a special surface, such as a chalkboard, and have the image appear at remote screens. Presently, a user wishing to call attention to an entry already written on the board must make a new line or must circle the item to which the remote viewer's attention is to be drawn. This procedure unduly clutters the image and a system has been devised which provides for a cursor (a graphical hand) to appear on the remote screen when the user to...

A slide rule is provided with a cursor comprising two transparent face plates, each carrying a hairline indicator, which are joined together and hold an end slide member between them at each end of the cursor by connecting means which include an eccentric adjusting member that can be displaced incrementally by a user of the slide rule so as to displace one of the face plates relative to the other for precise realignment of the positions of the hairlines relative to scales on both sides of the ru...

The movement volumes of X and Y to the X axial direction and the Y axial direction and the rotate angle .theta. of the coordinate input device moved on the substrate, are calculated by the input controller. The calculating device outputs instruction signals to the display device to move the cursor displayed on the display device by the movement volumes of X and Y, and rotate the cursor by the rotation angle corresponding to that calculated by the input controller.

A slide rule cursor which is adapted for use with conventional slide rules to provide direct resolution of the resultant value of parallel and/or series impedances. The cursor is not only movable axially along the body of the slide rule in a conventional manner but is also movable perpendicularly to the axial direction of the body of the slide rule. The cursor has printed on it a series of curves from which unique values of a special coefficient referred to as .mu..sub..theta. may be readily obt...
