A method of and apparatus for transmitting video images allows a viewer to receive at a receiving display device, all or a selected portion of a video stream of frames, in a storage-efficient format from a transmitting device and view the received video stream of frames before the transmission is complete. The video system also allows a viewer to receive at the receiving device, all or a selected portion of a video stream of frames, in a high-resolution format, by marking sections of interest within the received stream of frames in the storage-efficient format and requesting enhancement of those marked sections of interest. This apparatus preferably includes a source device, a transmitting device and at least one receiving device. Preferably, the transmitting device and the receiving device communicate over a network such as the Internet Protocol network. Alternatively, the transmitting device and the receiving device communicate over any appropriate data network. The transmitting device transmits the video images to the receiving device for display and storage at the receiving device. The receiving device is also capable of communicating with the transmitting device while simultaneously receiving video images. The source device is preferably a medical test device such as an ultrasound, a sonogram, an echocardiogram, and the like. Alternatively, the source device can be any video capture or storage device capable of sourcing a stream of video frames.

System for transmitting video images over a computer network to a remote receiver

An improved control system for a stepper motor coil includes a flyback circuit that dissipates coil energy slowly while the coil is energized and operated in the chopping mode, while dissipating coil energy rapidly when the coil is switched to its de-energized phase.

Specimen processing and analyzing systems with variable zener-diode

An assembly for identifying the results of a specimen analysis wherein such specimen analysis occurs in an array of discrete cells. The assembly includes a housing having top, bottom, end walls, and sidewalls. An array receiving recess is provided on the top wall for receiving and holding in a fixed position the array of the discrete cells. An ultrasonic signal producing stylus is provided for selectively producing an ultrasonic signal adjacent a cell in the array in which the results of the analysis are to be identified. A first ultrasonic signal transducer is provided on the top wall for converting the ultrasonic signal from the ultrasonic signal generator to a first electrical signal. A second ultrasonic signal transducer is provided on the top wall for converting the ultrasonic signal from the ultrasonic signal generator to a second electrical signal. A microprocessor is provided electrically operatively connected to the first ultrasonic signal transducer, the second ultrasonic signal transducer, and the ultrasonic signal producing stylet. The microprocessor compares the first and second electrical signals received and identifies such signals to the cell above which the ultrasonic signal was produced.
