摘要： An improved means for rapidly compressing, expanding, and displaying broad band information which is transmitted over a narrow band communications channel. In the preferred embodiment, a video image is cyclically assembled in low resolution and high resolution phases from digitized data representing gray level intensity for individual pixels which have been grouped into cells. During the initial cycle of the low resolution phase, a representative sample of said cell intensity values is transmitted by a sending station to a receiving station according to a video compression routine. Said receiving station then uses a video expansion routine to calculate an intensity value for those cells and pixels whose intensity values were not transmitted and displays an initial image. This image is refined during subsequent low-resolution cycles by means of additional transmissions from the sending station which replace the calculated cell intensity values with an actual value for that cell. During the high resolution phase, an error determination routine or external input from a viewer selects those cells containing the greatest deviation in intensity levels from the input video image. The error compression and expansion routines substitute a plurality of individual pixel intensity values for single cell intensity values. The present invention also discloses a means for allowing color capable stations to send or receive color transmissions while retaining the capability to interact with noncolor stations. Color data is compressed and interleaved with black and white data by a color capable sending station and subsequently separated and expanded by a color capable receiving station.

摘要： A system for sensing the spatial position of a moveable object (14) with respect to an energized conductive surface (10,12) whereby the spatial coordinates (x, y) of the object are determined. The system provides a means of accurately measuring the coordinates of the object with respect to a two-dimensional coordinate system independent of the third orthogonal dimension, thereby avoiding significant measurement errors due to variations ofthe object's position in the third orthogonal dimension. The system also ascertains the coordinate (z) of the object in this third dimension, which can then be utilized as an independent control variable in the system. Further, the system can accommodate a number of energized conductive surfaces over which the object may be positioned and can determine the spatial coordinates of the object with respectto any such surface. ln general,the system of the present invention can ascertain the generalized n-tuple position vector of the object with respect to each of a plurality of generalized, energized conductive surfaces. In any of the foregoing forms, the energized conductive surfaces can be transparent.
