Abstract: A stylus body is provided and has a generally elongated shape. A tip member (220) extends from the front of the stylus body, the tip member preferably being elongated and narrowing to a point at its front end. A pair of spaced conductive wires (280) are disposed in said tip member. A plurality of apertures (223) are provided in the narrowing portion of the tip member, these apertures permitting efficient emission of acoustic energy from the spark gap at the wire ends. By having the spark gap substantially centrally within the tip member and close to the stylus point that contacts the working surface, the errors and inconsistencies that can result from different rotational orientations and/or tilts of the stylus are minimized.

Abstract: An apparatus is disclosed for determining the position of a moveable element (130). First and second spaced apart optical receiving assemblies (110, 120) are provided for receiving light from the moveable element. Each of the optical receiving assemblies includes an array of photosensitive elements (270, 370), a cylindrical lens (260) for receiving light from the moveable element, and a fiber optical block (250), formed of a multiplicity of optical fibers, optically coupled between the cylindrical lens and the array of photosensitive elements. An optical diffuser (259) is provided on the input surface of the fiber optical block, the diffuser operation to scatter some of the arriving light, and causing more light to be captured by the optical fibers, particularly near the ends of the fiber optical block. Also, the efficiency of a light-emitting cursor is increased by directing light that would otherwise be lost in the vertical direction, into a generally flat beam. This is achieved with a toroidal lens (1280) having a convex periphery.

Abstract: A monostable multivibrator circuit for producing a pulse of a fixed duration including a first D-type flip-flop having set, reset, clock and delay inputs, and a second D-type flip-flop having set, reset, clock and delay inputs. A trigger pulse triggers a change in state of the first D-type flip-flop, in turn causing a change in state in the second D-type flip-flop. The output of the second D-type flip-flop contains a capacitor storage circuit which serves to bypass the change in state of the second D-type flip-flop for a predetermined delay time, and feedback an exponentially increasing level to the first D-type flip-flop. When the charge across the capacitor reaches the threshold level of the first D-type flip-flop, the first flipflop output again changes condition, causing the second output to change correspondingly.

Abstract: A device for digitally indicating the center of a pulse employing a pulse counter and a pulse generator having a fixed generating rate. Upon receipt of an initial pulse a first flipflop opens a first gating circuit and passes pulses to the counter. A second flip-flop receives the leading edge of a subsequent pulse to turn off the first gate and opens a second gate. The second gate in turn allows pulses at one-half the fixed generating rate to accumulate in the counter. The trailing edge of the second pulse changes the state of the second flip-flop and turns off the second gate. The accumulated count is now representative of the measure from the initial timing pulse to the center of the second pulse. A further flip-flop, upon receipt of a further pulse, changes state and insures that the gating circuits do not open to permit further counting. The two level counting is accomplished by a pulse frequency dividing stage connected to the pulse source, or, alternatively, by using the output of the first counter stage.
