摘要： A transmitter pulse circuit produces two-phase pulse trains containing a certain number of pulse edges corresponding to an integral number represented by binary parallel bits of a data value to be transferred. The transmitter responds to a coordinate data value derived from a digitizer. The receiver includes a counter for counting pulse edges contained in the two-phase pulse trains, and a retrieving circuit for retrieving intermittently the counted contents to determine the number of received pulse edges. The counting circuit and the retrieving circuit constitute together a bus mouse interface of a host computer in the receiver. The coordinate data can be transferred to the host computer through the bus mouse interface without using a general RS-232C interface, thereby efficiently improving the host computer multiple terminal processing capacity.

摘要： The position on a surface of an implement including a tuned circuit with a predetermined resonant frequency is determined and displayed by an apparatus having a housing including the surface. A tablet in the housing includes coils arranged in two coordinate directions parallel to the surface. The coils are excited with AC energy having approximately the same frequency as the resonant frequency. The tuned circuit interacts with the AC energy to change the AC current flowing in the coils as a function of the implement on the tablet. An electronic two-coordinate direction display in the housing configured as a plate is superposed with and lies in a plane parallel to the tablet and the surface. The display responds to the change in AC current resulting from the interaction between the AC energy and the tuned circuit to indicate the position of the implement on the surface.

摘要： A position detecting apparatus has a plurality of magnetostrictive transmission medium elements which are arranged substantially in parallel with one another. A first coil and a second coil are wound around these elements such that signals are exchanged between these coils through the intermediary of the magnetostrictive transmission medium elements. The electric-mechanical coupling coefficient of the magnetostrictive transmission medium elements is locally changed by a magnetism from a position appointing magnetism generator so as to appoint a position on a plane provided by the magnetostrictive transmission medium elements, and the appointed position is detected through detection of a change in the timing of a signal caused by the local change in the above-mentioned coefficient. The position appointing magnetism generator is not connected to any portion of the stationary part of the apparatus. The apparatus is capable of detecting the appointed position at a high resolution, even when the position appointing magnetism generator is spaced apart vertically from the position detecting region. This apparatus is usable also for a moving object, with the position appointing magnetism generator affixed to the moving object.

摘要： The position of an object including a retroreflector is determined by scanning first and second optical beams toward an axis on a planar surface from spaced sites on opposite sides of the axis. The scanned beams are incident on and reflected from the retroreflector along coincident first and second paths between the sites and the retroreflector. Indications are derived of first and second angles between a baseline between the sites and the first and second paths extending between the sites and the retroreflector. In response to the known distance between the sites and the derived indications of the first and second angles a two-coordinate direction indication of the retroreflector position is derived. The retroreflector refracts and reflects the scanned optical beams incident thereon and refracts the beams reflected thereby.

摘要： A position detecting apparatus for detecting a position appointed by a position appointing magnetism generator 7. The apparatus has at least one magnetostrictive transmission medium 1 and a first coil 2 and a second coil 5 around the medium 1 in such a manner that signals are exchanged between these coils 2,5 through the intermediary of the magnetostrictive transmission medium 1. The electro-magnetic coupling coefficient of the magnetostrictive transmission medium 1 is locally changed at a selected position by the position appointing magnetism generator 7, and this position is detected through the detection of timing of change in the signal level attributable to the change of the above-mentioned coefficient. The magnetism generator 7 need not be connected to any portion of the apparatus, and yet the appointed position can be detected at a high resolution even if the position appointing magnetism generator 7 is vertically spaced considerably from the position detection range. This apparatus can be used, for example, in the detection of position of a moving object, by attaching the position appointing magnetism generator to the moving body while laying the magnetostrictive transmission medium along the path of movement of the moving body.
