Abstract: A calibrated scanner is disclosed. The calibrated scanner includes a sensor board with a Charge Coupled Device (CCD) having two output signals. The sensor board also includes two offset devices, a coarse offset and a fine offset, the coarse offset being connected to the two output signals, the fine offset being connected to one of the output signals. The offsets are adjusted to provide a nonclipping DC bias for the two output signals. The sensor board also includes two gain devices, one gain device being attached to each output signal. The gain devices are adjusted to balance the two output signals. After these adjustments, the saturation level of the CCD is determined. The saturation level information is then used in readjusting the gain and offset devices. After this calibration, a linear correction may be applied to the output signal of the sensor board. The linear correction is accomplished by determining dark and light values of the sensor board.

Abstract: A color slide transparency scanner projects an intense stripe of light through a color slide. Red, green, and blue filters successively filter the stripe of image from the slide. In some applications, a neutral density filter adds still more information from dark areas of the slide image. A carriage carrying the slide moves across the light. A CCD array detects the filtered images and converts them to analog electrical signals. Circuitry converts the analog signals to digital.

Abstract: An ink jet printing system comprising a plurality of ink jet printheads each having a matrix of ink jets, each jet having a nozzle constituting a valve seat at its outlet end, the seat having an orifice for ejection of drops of ink, a solenoid-actuated valve member engageable with and disengageable from the seat to close and open the orifice, a controller for each printhead comprising a microcomputer for processing data for actuating the solenoids to print messages and storing the data, a console for all the printheads having a microcomputer for processing data for delivery to the printheads and operable to store data for a plurality of messages, and a terminal for generating data for messages for delivery to the console or, alternately, directly to the printhead controllers for a minimum system.

Abstract: Apparatus for receiving video output from a patient scanning device and photographing a plurality of video displays sequentially in multiple images onto a sheet of x-ray film. A video monitor adapted for connection to a scanning device, such as a gamma ray or ultrasonic imaging system, and having a display tube mounted in a housing in spaced relation to a wide angle lens formed to project the image of the face of the display tube onto a sheet of film supported in a film holder mounted on the housing. The positioning of the image on the film is determined by the vertical and lateral positioning of the lens relative to perpendicular X and Y axes corresponding to the length and width of the film. The lens is provided with a shutter for controlling the passage of light therethrough, and a pair of reversing electric motors are provided for selectively positioning the lens along the X and Y axes.

Abstract: Apparatus for synthesizing motion pictures of a cyclically functioning internal body organ such as a human heart from the monitor control (X, Y, and Z) signals provided by a scintillation camera excited by radiation from a bolus of radiopharmaceutical material transiting or standing in the organ. The individual frames of the synthesized motion picture are recorded on a disc of photographic film which is rotated step-by-step by a digital rate-and-position servodrive. The picture quality of each frame is enhanced by repeatedly exposing it to the monitor screen image during substantially the same phase of successive functioning cycles of the organ. The organ cycle phase signals which serve as step commands for the servodrive are generated by a synchronizing circuit which is itself synchronized to the cyclic rate of the body organ being examined by means of bioelectrical signals derived from the patient being examined.
