Abstract: A biological sample is analyzed for presence of a causing agent such as a virus, bacteria or cancer which generates a series of different states in the sample. The sample is separated into sub-samples where at least some of the sub-samples include portions of the sample at different states. Electromagnetic radiation interacts with the samples to obtain a spectrum of sub-sample properties which is compared with a plurality of reference spectra obtained from testing a plurality of sub-samples in respective ones of the different states to calculate a population distribution of the states of the sub-samples to obtain information about the causing agent. The population distribution can be analyzed at a single time or temporally over time to generate data relating to an effect of the causing agent. The population distribution is compared with a plurality of reference population distributions to generate data identifying the causing agent.

Abstract: A method and system for activity classification. A pressure sensor receives input data resulting from physical activity of a subject performing an activity. The input data includes pressure data from at least one pressure sensor, and may include other data acquired through other types of sensors. A deep learning neural network is applied to the input data for identifying the activity. The neural network is trained with reference to training data from a training database. The training data may include empirical data from a database of previous data of corresponding activities, synthesized data prepared from the empirical data or simulated data. The training data may include data from physical activity of the subject being monitored by the system. Different aspects of the neural network may be trained with reference to the training data, and some aspects may be locked or opened depending on the application and the circumstances.

Abstract: Systems and methods have been developed for implementation of a breath testing system for convenient sampling of intestinal gases exhaled from a patient's breath. This may include a system with a manifold that includes thermal regulation components, for instance thermistors and resistive heating elements, which maintain the temperature of the gases above the body temperature of the patient. In some examples, the system will determine an indication of whether a patient has SIBO by adjusting a change in exhaled hydrogen concentration by a methane level exhaled by a patient.

Abstract: The present disclosure relates to aerosol delivery devices. The aerosol delivery devices include mechanisms configured to deliver an aerosol precursor composition from a reservoir to an atomizer including a heating element to produce a vapor. A pressure controller may control dispensing of the aerosol precursor composition from the reservoir based on a pressure differential between a first pressure within the reservoir and a second pressure proximate the atomizer. The first pressure within the reservoir may be substantially equal to atmospheric pressure. Alternatively, the first pressure within the reservoir may be greater than atmospheric pressure.

Abstract: A method for regulating flow of electromagnetic radiation into a volume such as a duct includes defining on a reflective surface an array of two or more ridges which are arranged side by side and projecting toward the source. Each ridge is formed by reflective ridge surfaces converging toward an apex so that the reflection directions of the surfaces are different. The ridges are arranged relative to the source so that first reflective ridge surface reflects primarily toward the upstream location and second reflective ridge surface reflects onto the first reflective ridge surface of a next adjacent ridge and thereby primarily toward the upstream location so that the array of ridges acts to form a restriction to flow of radiation toward the downstream location. This can increase an amount of the radiation within the duct by reflecting the radiation back into the duct and to reduce an amount of radiation escaping the duct.
