  • Publication number: 20230380770
    Abstract: Blood pressure measurement through the use of a sensor array system capable of tracking displacement, motion, environmental impact, and other electrical signals, and recalibration based on said tracking. The sensor array system may comprise a plurality of sensors, and each sensor may be capable of measuring one or more parameters. The system may further comprise an electronic board communicatively coupled to the sensor array. The electronic board may be capable of transmitting a plurality of parameter measurements from the sensor array to a computing device capable of detecting changes to the sensor array based on the plurality of parameter measurements. The changes to the sensor array may be detected by measuring an increased parameter reading from at least a first sensor and a decreased parameter reading from at least a second sensor compared to a baseline measurement.

  • Patent number: 8827905
    Abstract: The present invention is a system and method of remote patient monitoring to allow a patient to initiate and activate sensing systems. In the system and method, standard parameters can be sensed, and the information can then be processed and sent to the physician or clinician. The clinician then has the ability to remotely configure or reconfigure the parameters of the sensing system so as to probe for more targeted information based on the initial sensed data.

  • Publication number: 20070156450
    Abstract: The present invention is a system and method of remotely monitoring patient health care characteristics. The system utilizes at least two micro-scale to millimeter-scale sensors, a wireless network, a central hub and pre-processing center and a means for notifying a clinician of the remote patient's condition. The system and method includes sensor to sensor coordination, modular-based sensors and processing, and allows a clinician to remotely configure the system.

  • Publication number: 20070118399
    Abstract: An informatics system permits data entities from a wide range of data sources to be accessed and evaluated. The sources of the data entities may be simply data sources, such as for articles and other non-patient or population specific information, as well as controllable and prescribable sources, such diagnostic imaging, clinical and other sources forming part of the patient care path. The entities are organized, analyzed in accordance with a domain framework, which may be altered by a user to focus on factors and informational components of interest. Holistic and integrated understanding of such factors are there fore available, and refinement of healthcare processes can be made to provide improved care in a more time and cost effective manner.
