Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to a Sensor for monitoring acetone emitted from the surface of the skin. The Sensor includes a gas impermeable enclosure and a carbonate removal cell enclosed within the gas impermeable enclosure. A gas permeable membrane houses the gas impermeable enclosure. A fuel cell anode is situated adjacent to the gas permeable membrane. At least a portion of a reference electrode is enclosed by a first portion of the fuel cell anode. A bottom surface of the carbonate removal cell is composed of a top surface of a second portion of the fuel cell anode. A top surface of the reference electrode and a top surface of the first portion of the fuel cell anode are in contact with a bottom surface of the gas permeable membrane.

Systems and methods for monitoring of acetone

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to a Concentration Prediction Platform. According to various embodiments, the Concentration Prediction Platform receives an electrochemical signal and generates data based on deconvolving a respective contribution of an analyte(s) influencing the electrochemical signal. The Concentration Prediction Platform sends the data into one or more machine learning networks. The Concentration Prediction Platform receives, from the one or more machine learning networks, a predicted concentration of an analyte(s) influencing the electrochemical signal.

Systems and methods for predicting analyte concentrations via machine learning techniques

A method for retrieving information is provided. The method uses a server system coupled to a centralized database and at least one client system. The method includes selecting an object from an electronic document displayed on a client system, displaying a function menu on the client system to prompt a user to select a desired function, transmitting the selected object and a selected function from the client system to the server system, processing the selected object by applying the selected function at the server system, communicating with a vendor web server to complete the processing of the selected object, and transmitting at least one of a resulting web page and other output to the client system.

Methods and systems for retrieving information over a computer network

A method and infrared sensing device for determining the concentration of alveolar alcohol in a breath sample exhaled by a subject into an infrared sensing device. The presence of alcohol from the upper respiratory tract of the subject is detected by continuously monitoring alcohol and carbon dioxide, normalizing alcohol values with respect to carbon dioxide, calculating a difference between normalized alcohol concentration and carbon dioxide concentration over time, integrating (summing) the difference, and comparing the integrated difference with a threshold. This technique accurately and consistently detects the presence of mouth alcohol in the sample before the presence of carbon dioxide which originates in deep lung breath.

Apparatus for testing breath alcohol with discrimination between alveolar and upper respiratory tract alcohol

A system and method for checking the calibration of a breath alcohol measuring instrument by the use of alcohol standards all containing substantially identical concentrations of alcohol and the use of a calculator which generates an expected measured value for the standard based on the known alcohol concentration and current atmospheric pressure.

System and method of checking calibration of breath alcohol measuring

A method and apparatus for measuring the concentration of breath alcohol or other reactants is provided in which a breath sample is introduced to a fuel cell, wherein the number of electrons from the fuel cell resulting from oxidation of the alcohol in the breath rises to a peak and thereafter falls to a substantially steady minimum base to form a curve. The present method is based on the discovery that this curve, regardless of reactant concentration or age of fuel cell, is a log-normal distribution curve.
