Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

A system for storing and releasing gasses for a breathalyzer test is provided. The gas cartridges and containers of the system can store and release various gaseous mixtures including exhaled air samples. The system can be used for testing breathalyzer devices. These devices include, for example, small hand-held units and larger units that are built into vehicles such as automobiles and trucks. The system is particularly suitable for breath alcohol ignition interlock devices that are used to prevent a driver from operating a motor vehicle when their blood alcohol concentration is at a certain level. In yet another embodiment, the container assembly is used when there is a alcohol sensor for the steering wheel in the vehicle as opposed to a breathalyzer device.

Systems and methods are provided that include forming a classification model associated with a respiratory disease based on training audio data, where the training audio data is characterized by a pre-existing correlation with the respiratory disease. In an embodiment, the method can include normalizing the training audio data, removing portions of the training audio data below an audio energy threshold to produce thresholded audio data, segmenting the thresholded audio data into uniform time segments, extracting MFCC coefficients and RASTA-PLP coefficients from the segmented thresholded audio data, generating a feature matrix using the MFCC coefficients and RASTA-PLP coefficients, and classifying the feature matrix based on the pre-existing correlation to form the classification model using a multilayer perceptron technique. Systems and methods can further include generating a probability of a diagnosis based on acquired audio data and the classification model.

An apparatus estimates vital signs of a person from video images with color channels representing a digitization of optical sensor signals. A first detector (203) detects a first image area being a skin area of the person and a second detector (205) detect a second image area corresponding to a different area of the person than the first image area. A determiner (207) determines color channel distributions for pixels of the first image area. A processor (209) provides a skin tone indication and a reference processor (211) provides a reference color channel distribution property for the skin tone. A gain processor (213) determines gains for the optical sensor signals in dependence on a luminance property of the second image area and on a comparison of the reference distribution property and a property of the color channel distributions. A gain controller (215) accordingly controls gain values applied to the optical sensor signals and a vital sign determiner (217) estimates a vital sign property for the person from the images.

Embodiments of the present technology include a wearable physiological monitoring device, related algorithms and software that are tied to a portable electronic device for readout. The wearable device can perform real-time measurement of a number of physiological and environmental parameters including heart rate, pulse oximetry, respiration, movement, environmental particulate matter, moisture, temperature (e.g., ambient air and body temperatures) and geospatial location. Some embodiments may establish a physiological baseline for a patient by measuring the above parameters during a healthy state. Collected data can be wirelessly transmitted to a portable electronic device or monitoring and feedback platform where software will analyze the data and make assessments of the device wearer's health based upon the wearer's baseline.

One embodiment is a method of performing thoracic tomography on a human subject including performing multiple 4-wire impedance measurements on a region of interest to obtain measured impedance data; comparing the measured impedance data to simulated impedance data obtained from a plurality of models of the region of interest; for each of the models, determining a fit of the model based on a comparison between the simulated impedance data obtained from the model and the measured impedance data; and integrating individual resistivity estimates obtained from the models based on a fit of the model such that the individual resistivity estimate from a better fitting model is weighted more heavily in a final resistivity estimate than an individual resistivity estimate from a worse fitting model.
