Abstract: A non-invasive patient monitoring sensor configured to monitor at least one physiological parameter of a patient utilizing at least one light emitting LED and at least one photodetector aligned on opposing sides of a sensor site to detect light transmitted thorough a tissue area of the patient. The patient monitoring sensor includes one or more layers of light absorption material configured to enable accurate SpO2 measurements of patients providing a non-disparate performance for patients of any skin pigmentation type, including light skin pigmentation, intermediate skin pigmentation and dark skin pigmentation. In exemplary aspects, the patient monitoring sensor is configured to have an overall accuracy root mean square (ARMS) of less than 3.0% measured across the saturation range of 70-100% for skin pigmentation types.

Abstract: The present invention is directed to methods for amplifying vocal (i.e., speech) and other sounds produced by humans and other animals. The present invention provides implantable microphones and sound amplification systems suitable for use in diagnostic and research settings, as well as for use by subject's in need of assistance to vocalize.
