Abstract: Described herein is a wavelength reference device comprising a housing defining an internal environment having a known temperature. A broadband optical source is disposed within the housing and configured to emit an optical signal along an optical path. The optical signal has optical power within a wavelength band of interest. An optical etalon is also disposed within the housing and positioned in the optical path to filter the optical signal to define a filtered optical signal that includes one or more reference spectral features having a known wavelength at the known temperature. The device also includes an optical output for outputting the filtered optical signal.

Abstract: This document describes techniques and devices for Fourier-transform infrared (FT-IR) spectroscopy using a mobile device. A mobile device (502) includes a light source (504) that emits light toward an interferometer (508) that uses mirrors to separate and recombine the light. The interferometer directs the recombined light toward a person. Light reflected from, or transmitted through, the person is received through a reception port (506) to a photodetector (510) that outputs photodetector data that corresponds to a measured light intensity of the reflected and transmitted light as a function of a path length of the light or a mirror position of the interferometer. Based on the photodetector data, an interferogram is generated. Applying a technique such as a Fourier transform to the interferogram, a spectrum data set of the reflected and transmitted light is generated. Based on the spectrum data set, a concentration of solutes in the person's blood is calculated.

Abstract: A remote sampling sensor for determining characteristics of a sample includes measurement optics and an insertion probe. The measurement optics are configured to emit light and detect returned light. The insertion probe includes a chamber, the chamber being configured to permit the sample to enter the chamber, an insertion tip at a distal end of the insertion probe, and a retro-reflective optic adjacent the insertion tip. The retro-reflective optic is configured to return the light from the measurement optics through the chamber to the measurement optics. The insertion probe is configured to be remotely located from the measurement optics.

Abstract: A portable optical spectroscopy device is disclosed for analyzing gas samples and/or for measurement of species concentration, number density, or column density. The device includes a measuring chamber with the gas sample to be analyzed, a light source with at least one laser diode for emitting a laser beam along a light path running through the measuring chamber at least in certain regions, means for modulating the wavelength of the light beam emitted by the light source, and an optical detector device having a first optical detector and at least one second optical detector. At least a part of the light emitted by the laser diode is detected after the light has passed through the measuring chamber m-times, and at least a part of the light emitted by the laser diode is detected with the at least one second optical detector after the light has passed through the measuring chamber n-times, where n>m applies.

Abstract: Systems and methods for color selection are provided. A user device displays room types on a display, receives a room type selection indicating a particular room type, displays types of feelings, and receives a type of feeling selection indicating a particular type of feeling. The user device accesses a lookup table that associates the room types and types of feelings with paint colors such that each possible combination of room type and type of feeling is associated with a subset of paint colors. The user device determines the associated subset of paint colors in the lookup table for the combination of the particular room type and the particular type of feeling and displays the associated subset of paint colors as recommended paint colors for the combination of the particular room type and the particular type of feeling on the display of the user device.

Abstract: Apparatus and methods provide wireless, disposable, continuous pulse oximeter sensor technology, useful and beneficial for a number of applications including relatively extended periods of data collection, and/or packaged in compact and easy-to-use assemblies. Economic fabrication and use provides flexible methodologies that can reduce the overall costs of monitoring and collecting patient's physiological data, and provide relatively greater ease and comfort to the patient. A disposable wireless continuous pulse oximeter sensor has a reduced emitter-detector separation, a low-power frontend, and a low-cost processor that sends waveforms to a host device so that the host can calculate and display the parameters of interest. Complications created by the reduced distance between emitter and detector are minimized by using an emitter-detector assembly with an optically dark background, and a bandage for improved optical compliance.
