An apparatus is provided for assisting players during practices or games in games, such as basketball, in which a ball or other object is directed toward a desired location. A video camera detects the ball and provides a signal indicating the location of the ball. A processor uses the location to determine an optimal location to direct the ball, and provides a signal to an illumination system. The illumination system provides a visual indication of where the player should direct the ball. The apparatus should be able to accommodate a game in which a ball may move quickly.

Guiding system for athletes

There is disclosed a control apparatus which controls the presentation of electronic data per scanning line to an image recording material.

Control apparatus for electronic image printer

An electronic imaging system includes a linear LED array for recording on a photosensitive medium an image defined by electronic signal information in binary word format by simultaneously controlling the energization of all the LED's at a constant energy level in a series of intervals, each of which is timed differently to correspond to a different one of the data bits in the binary words which comprise the image defining electronic signal information. Each LED is energized during each interval as a direct function of the state of the data bit corresponding to that interval for that LED.

Parallel LED exposure control system

A control system for controlling the size of the image produced by pixels generated by a raster scanner employing a binary rate multiplier for image size control along the X-axis, the multiplier being programmed to the size image desired to vary the frequency of the pixel clock signals output by the multiplier, together with a control flip-flop astride the image pixel stream and driven by the multiplier clock signals to speed up or reduce the rate at which image pixels are output. For image size control along the Y-axis, a phase lock loop is provided for controlling scanning carriage speed in response to the frequency of the signals output by a programmable frequency generator.

Image magnification and demagnification system

A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

Modular array

Crossover arrangement for multiple scanning arrays

A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.
