Patents by Inventor Stephen Douglas Fisher

Stephen Douglas Fisher has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8294588
    Abstract: A patient monitoring system detects physiological signals from a patient during an MRI examination. The patient monitoring system wirelessly transmits data associated with the physiological signals to a remote base unit. The wireless transmission of data is carried out in a manner to not be disruptive to the MRI examination. The patient monitoring system has a removable, MRI magnet compatible battery.
    Type: Grant
    Filed: May 10, 2007
    Date of Patent: October 23, 2012
    Assignee: Koninklijke Philips Electronics N.v.
    Inventors: Stephen Douglas Fisher, Robert A. Harwell, Kenneth Van Arsdel
  • Patent number: 8121667
    Abstract: A base unit operable with a wireless patient monitoring unit used to acquire physiological data during an MRI examination is constructed to have a detachable display unit. The detachable display unit wirelessly communicates with the base unit when in a roving mode. The detachable display unit may also have a magnetically-hardened power supply that does not saturate during an MRI examination. Such a magnetically-hardened power supply allows the display unit to operate when proximate or in the magnetic field generated by an MRI machine during an MRI examination.

  • Patent number: 8098149
    Abstract: A wireless patient monitor for MRI provides for on-board filtering of physiological signals from the patient to provide improved assessment and processing of MRI noise before the signal is affected by the transmission process. A system of powering of a wireless patient monitor using capacitors is also provided.

  • Publication number: 20100192141
    Abstract: A patient monitoring system detects physiological signals from a patient during an MRI examination. The patient monitoring system wirelessly transmits data associated with the physiological signals to a remote base unit. The wireless transmission of data is carried out in a manner to not be disruptive to the MRI examination. Data can be uploaded to or downloaded from the patient monitoring system and remote base unit using a magnet-friendly electronic storage device, such as a flash memory drive.
