Abstract:
Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed.
Abstract:
An earpiece module includes a physiological sensor, an external energy sensor, a transceiver, a communication module, a data storage component, and a power source. The communication module includes a microphone, a speaker, and a signal processor. The signal processor processes audio information received from a remote source via the transceiver and communicates the processed audio information to a subject via the speaker. The signal processor processes information in real time from the physiological sensor and the external energy sensor, and the signal processor provides biofeedback to the subject based on signals produced by the physiological sensor. The data storage component includes a plurality of algorithms. At least one algorithm focuses processing resources on extracting physiological information from the physiological sensor, at least one algorithm is configured to be modified or uploaded wirelessly via the transceiver, and at least one algorithm is a compression/decompression (CODEC) algorithm.
Abstract:
A meteorological tower is provided in a flux site and a solar array is positioned on the tower to provide power. A laser on the tower receives power from the solar array and produces a laser beam. A multiplicity of individual laser absorption spectroscopy gas cells positioned on the meteorological tower collect samples of the atmosphere. An optical cable connects the laser to each of individual las cell and direct the laser beam into each cell. Each cell includes a multiplicity of mirrors positioned so that the laser beam makes a multiplicity of passes through the samples. An analyzer associated with the cells receives the laser beam after the laser beam has made the multiplicity of passes through the sample of the atmosphere and the analyzer detects concentrations of isotopes of carbon dioxide in the atmosphere in concomitance of other gas concentrations.
Abstract:
A grain measurement device (76) comprises a chamber (80) having an inlet (82) and an outlet (84) for grain that is to be tested. A spectrometer is equipped with a light source (89) and a detector (91) for light which was generated by the light source (89) and was transmitted through the sample. The detector (91) is connected to an analyzer (134) for wavelength-resolved analysis of the received light. A mounting (93) of one of the light source (89) or detector (91) can be moved with respect to the other (91, 89 by a drive (106), which moves the mounting (93) for purposes of conveying the sample either in the flow direction (130) or in the opposite direction, in order to break up the sample or to avoid bridging and/or jamming of the sample in the measurement chamber (80).

Abstract:
A fitting for positioning a probe in a hot gas path within a casing of a gas turbine engine is disclosed herein. The fitting may include a main body attachable to the casing opposite the hot gas path. The main body may include an internal bore and one or more cooling holes in communication with the internal bore. A compliant seal may be positionable within the internal bore. In addition, a follower may be positionable within the internal bore adjacent to the compliant seal. Moreover, the fitting may include a fastener configured to mate with the main body. In this manner, the follower may deform the compliant seal about the probe within the main body to secure and seal the probe within the main body.
