  • Assessing noise on a communication channel
    Patent number: 8996124
    Abstract: A system and method involve transceiving successive first and second synchronization signals defining endpoints of a frame. A digital signal is transceived by a modulating time interval between portions of the first and second synchronization signals. A first data pulse is transceived during the frame. A relative position in the frame of the first data pulse represents a first analog signal.
    Type: Grant
    Filed: August 26, 2008
    Date of Patent: March 31, 2015
    Assignee: Data Sciences International, Inc.

  • Pressure transmission catheter with sheath
    Patent number: 7464602
    Abstract: Methods and apparatus for sensing pressure are disclosed. One disclosed pressure measuring device comprises a pressure transmission catheter including a stem portion and a sheath fixed to the stem portion. The disclosed sheath comprises a wall defining a cavity that is in fluid communication with a stem lumen defined by the stem portion. The disclosed sheath has a first transverse extent and a second transverse extent that is different from the first transverse extent.

  • Frame length modulation and pulse position modulation system
    Patent number: 7418297
    Abstract: A system includes a transceiver circuit to transceive at least a first analog signal and a digital signal. The system also includes a controller circuit, coupled to the transceiver circuit, to deliver at least one control signal thereto, the controller circuit including executable instructions defining a data frame for communication of the first analog signal and the digital signal, endpoints of the data frame defined by portions of successive first and second synchronization signals and defining a corresponding frame interval, the data frame including a first data band for transceiving a first data pulse therein. A relative position in time of the first data pulse represents the first analog signal, and a modulation of the frame interval represents the digital signal. The system further includes an analog signal interface circuit, coupled to the transceiver circuit, to provide at least the first analog signal representative of acquired data.
