In a photographic process printer system that receives printable pixel data into a print engine component from a computer component over a high-speed fiber channel communication pathway. Feedback control messages from the print engine component are sent over a low-speed serial channel communication pathway to the computer component to control the transmission of printable pixel data. The computer component continues to transmit packets of printable pixel data over the high-speed fiber channel communication pathway as long as the feedback control messages indicate that the print engine component is ready to receive more packets of printable pixel data.

Fiber channel data transfer with feedback control within a photographic

The present invention provides a medical ultrasonic imaging device with dynamic focusing that is capable of operating at high frequencies and providing high resolution. One embodiment of the device includes a plurality of transducers, arranged in either a linear or curved array, for converting an ultrasonic signal received by the device into a plurality of electrical signals. This embodiment of the device also includes a plurality of vector modulators for phase-shifting the plurality of electrical signals to achieve fine focusing. A delay line array is further included in the device that allows each of the phase-shifted electrical signals to be delayed by a selected amount to achieve coarse focusing of the electrical signals. Further included in the device is a summer of summing the time delayed and phase-shifted electrical signals to provide focused image data.

Medical ultrasonic imaging system with dynamic focusing

An ultrasound imaging system is provided having an articulated arm for holding a transducer. Signals representative of the angular position of the arm joints are scaled up to a voltage range over which the restricted range of movement of each joint is distributed. The scaled signals are combined to produce a plurality of combined angular signals, which then may be digitized and used to compute the X-Y position of the transducer.
