  • SYSTEM AND METHOD FOR OPERATING A SENSOR FOR DETERMINING BLOOD CHARACTERISTICS OF A SUBJECT
    Publication number: 20150065830
    Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes receiving continuous photoplethysmographic (PPG) data of a subject from a sensor and calculating a continuous blood characteristic (BC) based on the continuous PPG data. The method also includes calculating a first quality metric of the continuous PPG data based on a sequence of the continuous BC. The method further determines whether the first quality metric satisfies a stability criterion and sending a first notification to the sensor in response to determining that the first quality metric satisfies the stability criterion. The first notification instructs the sensor to collect compressed PPG data of the subject.

  • Methods and apparatus for optical segmentation of biological samples
    Patent number: 8532398
    Abstract: A method for the imaging of protein expression and location in biological samples using optical segmentation is provided. The steps comprise acquiring a fluorescent image of a biological sample, analyzing the image and generating a masking pattern corresponding to a specific structure within the biological sample, transforming the masking pattern into the spatial coordinates of a digital micro-mirror device (DMD) which may then be projected onto the biological sample and obtaining a masked fluorescent image. Also provided is an image analysis system for imaging of protein expression and location in biological samples using optical segmentation.
