  • Telecommunications method and system
    Patent number: 8934571
    Abstract: A method for encoding data for transmitting over a telecommunications network comprising: embedding at least one control or pilot data block within a plurality of real data blocks in the frequency domain; transforming real data in the real data blocks with control or pilot data in the control or pilot data blocks; and modulating the real data blocks and control or pilot data block with one or more transmission sub-carrier signals.
    Type: Grant

  • Apparatus and method for constructing computed tomography image slices of an object undergoing cyclic motion
    Patent number: 6233478
    Abstract: Apparatus and method are provided for constructing image slices through a selected object undergoing a cyclic motion wherein a scanner is used for collecting image data associated with the selected object. A probe is provided for detecting a signal from the selected object, the signal being indicative of the cyclic motion of the object. The scanner and the probe are operatively connected with a controller. The controller receives the signal from the probe and generates therefrom a command for enabling the scanner to collect image data for producing one or more image slices through the selected object with minimized radiation exposure and data acquisition time.

  • Compensated pressure transducer
    Patent number: 5757608
    Abstract: The capacitance type pressure transducer is disclosed which includes an isolation additional diaphragm made of the same material as the operative diaphragms the transducer. Material may be quartz, silicon, or aluminosilicate. The isolation diaphragm minimizes deflections of the operative diaphragms as the housing base is bowed due to the pressure differential between the internal reference pressure of the capsule and the ambient pressure. The transducer may be configured to measure an absolute pressure or a differential pressure.
