20140252233 | METHODS, DEVICES AND KITS FOR PERI-CRITICAL REFLECTANCE SPECTROSCOPY - Spectroscopy apparatuses oriented to the critical angle of the sample are described that detecting the spectral characteristics of a sample wherein the apparatus consists of an electromagnetic radiation source adapted to excite a sample with electromagnetic radiation introduced to the sample at an angle of incidence at or near a critical angle of the sample; a transmitting crystal in communication with the electromagnetic radiation source and the sample, the transmitting crystal having a high refractive index adapted to reflect the electromagnetic radiation internally; a reflector adapted to introduce the electromagnetic radiation to the sample at or near an angle of incidence near the critical angle between the transmitting crystal and sample; and a detector for detecting the electromagnetic radiation from the sample. Also, provided herein are methods, systems, and kits incorporating the peri-critical reflectance spectroscopy apparatus. | 09-11-2014 |
20140051941 | OBTAINING PHYSIOLOGICAL MEASUREMENTS USING A PORTABLE DEVICE - An apparatus and method for obtaining one or more physiological measurements associated with a user using a portable device alone or in combination with a detachable unit is disclosed herein. One or more of different types of sensor sets are included in one or more planar surfaces of the portable device and/or the detachable unit in communication with the portable device. The accuracy of physiological measurements is automatically ensured by the fixed positioning of the sensors relative to each other. A variety of different physiological measurements can be obtained using a portable device that users normally carry around and use on a daily basis, instead of requiring use of a separate/dedicated medical device. | 02-20-2014 |
20140051940 | OBTAINING PHYSIOLOGICAL MEASUREMENTS USING EAR-LOCATED SENSORS - An apparatus and method for obtaining one or more physiological measurements associated with a user using ear-located sensors is disclosed herein. One or more of different types of sensors are configured to engage a user's ear. In some cases, the sensors will be included in one or both of a pair of earphones to capture physiological parameters.
