Abstract: A substance concentration monitoring method includes inserting a temperature probe noninvasively into a volume of a body in which a concentration of a substance is to be measured. An internal temperature of the volume is measured and an internal temperature signal is produced. An incident first near infrared beam in a first wavelength band is directed from a light source into a portion of the volume, the first wavelength band including a wavelength at which an absorption peak exists in a NIR absorption spectrum of the substance. An incident second NIR beam in a second wavelength band is directed from the light source into the portion of the volume, the substance exhibiting no absorption or negligible absorption in the second wavelength band. Substance concentration is calculated based on values corresponding to the internal temperature signal, a first and second initial power signal, and a first and second material absorption signal.

Abstract: System, method and media for quantifying bulbar function of a subject. At a high level, embodiments of the invention measure and quantify bulbar function of a test subject based on video data, audio data, or other sensor data of a subject performing a test of bulbar function, such as speech, swallowing, and orofacial movements. This sensor data is then analyzed to identify key events such as syllable enunciations. Based on one or more characteristics of these key events (such as, for example, their rate, count, assessed accuracy, or trends over time), the bulbar function of the subject can accurately, reliably, and objectively be quantified.

Abstract: The present invention provides a multi-section finger sleeve-type probe, which comprises a finger sleeve body, a flexible flat cable mounted on the finger sleeve body, a light emitting diode, a photo diode, and a wire electrically connected to the flexible flat cable. The finger sleeve body is a cylinder with an opening at the bottom thereof. Comparing with an existing finger sleeve-type probe in which wiring pipes are provided on both the left and right sides of a silicone sleeve and thus the silicone sleeve is flattened, the finger sleeve body fits the shape of a finger and fully wraps around the finger. While being used, the finger is inserted into the finger sleeve body and expands the periphery thereof, thus the finger is totally wrapped to provide a big resistance. The multi-section finger sleeve-type probe can be worn stably, be not easy to drop off, and be suitable for long term use.
