A pointing device includes a housing, a main body and an input section. The housing contains an upper cover and two extending arms, which extended from the upper cover. The main body is housed under the upper cover and located between the two extending arms of the housing. The input section is placed on the front half of the main body for generating (inputting) key signals. The front half (the input section) and the back half of the main body form a smooth surface.

An improved tuck pointing gun for repairing masonry structures and the like is provided which includes an elongated, tubular, mortar-receiving barrel, along with an improved, axially shiftable plunger within the barrel which is selectively shiftable therein through the usual ratchet rod and trigger mechanism associated with such guns. The plunger includes a thin, flat, circular, metallic plate having an annular, flexible member coupled thereto. The flexible member includes a forward beveled lip,...

A method for making a pointed, threaded fastener by threading, tapering and pointing in thread rolling equipment a screw blank having a cavity extending longitudinally into the blank from the end of the shank.

A thermometer-pointing apparatus which automatically performs the required facing operation and horizontal scanning to sense and accurately locate the top of a mercury column for purposes of pointing. For such purposes a photoelectric control system is connected with electromechanical means for manipulating the thermometer automatically as the top of the mercury column is being located and an improved optical system is provided for projecting a magnified image of the mercury column onto the phot...

Provided are a pointing device allowing accurate depressing operation on a key top and involving no erroneous input or erroneous operation, and a key sheet for the pointing device. On the back surface of a base sheet (14) of a key sheet (15) for a pointing device, an accommodating portion (17) for a magnet (13), for accommodating portion greatly protrudes toward a board (P) beyond a pusher (14b) is provided. When the key top (12) is depressed, the accommodating portion (17) and the magnet (13) c...

An optical pointing device for instructing a predetermined operation by moving an index over a display screen of a computer is configured such that a plurality of photocouplers are arranged on vertical sides and horizontal sides of a rectangular operation plane at a predetermined pitch in such a manner that lines of action thereof cross each other at a right angle, coordinates of a first shading pointer contacted to the surface of the operation plane are detected by the photocouplers, coordinate...

The present invention provides a computer pointing device which uses capacitors installed in various directions to generate pointing signals. The pointing device comprises a circuit board, a cap, and a detecting unit. The circuit board comprises a center point, a first conducting plate installed in a first direction and a second conducting plate installed in a second direction. The cap is movably installed above the center point of the circuit board. The bottom side of the cap has a top conducti...

A compact computer pointing device without moving parts detects the movement of objects, typically an operator's hand, in a detection area at a pre-selected height above the device. In an ultrasonic embodiment, the device includes two ultrasonic transmitter-receivers mounted at an appropriate position on the computer housing or keyboard. These transmitter-receivers use the Doppler effect to sense the vector velocity of objects moving in front of them. In an optical embodiment, the device consist...

A curved disc joystick or pad with improved performance, reliability and durability can be used as a cursor pointing device for computers, remote controls, video games, consumer electronics, industrial controllers, automotive and other applications. A conductive spring or sheath connects to a conductive curved rubber transducer which can be deflected to make contact with conductors on a printed circuit board, providing electrical outputs to a microprocessor or other device. A ribbed locking exte...

A pointing device that is ergonomically designed is shown and described. In a preferred embodiment designed for children aged 2-6, a relatively large ball is provided in a housing which has a gripping area or handle for each hand of a user, a portion of the ball extending from an upper surface of the housing. A button is provided in a front region of the housing, the placement, shape and size of the button being configured to optimize the target area and activation of the button by the user. The...
