  • Differentiation of fluid volume change
    Patent number: 11166671
    Abstract: A method for detecting evidence of a stroke in a patient may involve securing a volumetric integral phase-shift spectroscopy (VIPS) device to the patient's head, transmitting a first signal from a first transmitter of the VIPS device through a left hemisphere of the patient's brain to a receiver of the VIPS device, transmitting a second signal from a second transmitter of the VIPS device through a right hemisphere of the patient's brain to the receiver, and detecting the evidence of the stroke, with the VIPS device.
    Type: Grant
    Filed: January 20, 2017
    Date of Patent: November 9, 2021
    Assignee: Cerebrotech Medical Systems, Inc.
    Inventors: Mitchell Elliott Levinson, Eugene Mark Shusterman, William L. Shea

  • Visual medical sensor indicator
    Publication number: 20070282181
    Abstract: The disclosure includes a medical device having a disposable, replaceable or reusable medical sensor and a visual indicator of at least one condition. The disclosure also includes a method of determining exposure of a medical sensor to a condition by viewing a visual indicator of the condition on a medical sensor and, based upon viewing of the visual indicator, determining whether the medical sensor has been exposed to the condition.

  • Oximeter sensor with encoded temperature characteristic
    Patent number: 6356774
    Abstract: A method for operating an oximeter sensor, and corresponding apparatus, which includes an encoded temperature characteristic of a light emitter in the sensor. The encoded temperature characteristic is read, and is used to modify a drive of the light emitter in the sensor. This enables a light emitter to be operated at its maximum allowable intensity to maximize a signal to noise ratio, without burning a patient, in accordance with the particular characteristics of that light emitter.
