  • Patent number: 9345423
    Abstract: A method and apparatus for measuring user breath alcohol concentration. A flow of an expired breath sample is passed through a fuel cell sensor giving an output signal proportional to the amount of alcohol present in the sample. By measuring pressure, the volume of the sample may be calculated by integrating pressure over expiration time of the sample, whereas breath alcohol concentration is calculated based on the fuel cell output signal. Both sample volume and breath alcohol concentration values are continually updated by integrating measured instantaneous pressure and fuel cell output signal over time, irrespective of breath sample volume. When the user stops blowing, volume compensation is performed to obtain a compensated fuel cell output signal using a stored calibration volume. Hence, an improved method for accurately measuring breath alcohol concentration of a user is achieved, capable of handling varied expired volumes of breath, obviating the need for sampling mechanism.

  • Patent number: 8852117
    Abstract: Methods are disclosed for distinguishing whether an animal is experiencing a bacterial infection or a viral infection. One monitors breath taken from the animal over time to measure the relative amount of a first breath stable isotope to a second breath stable isotope therein over time. A quick change in the isotope ratios within several hours from the likely infection is indicative of a bacterial infection. A delayed change in the isotope ratios, followed by periodic repeated alterations in the ratios, is indicative of viral infection. The methods are particularly efficient when using cavity ringdown spectroscopy for the monitoring. They may be used for monitoring a patient already admitted to a hospital, or for monitoring a patient initially complaining of adverse symptoms, or for triage, or for collectively monitoring a population of animals.

The systems generally provide for accurate sample concentration being provided to the breath tester while also providing for a simplified system which can be easier to move, and require less operational complexity, than prior wet or dry calibrating systems.

  • Patent number: 8707758
    Abstract: A system and method of monitoring sobriety using a hand-held breath testing device that, on receipt of a user's breath, generates a breath test signal comprising substance content data and user identification data, and wirelessly transmits the breath test signal to a breath test signal receiving station. The breath test signal includes substance content data and user identification data. The substance content data includes at least one of: a blood alcohol level and a narcotics presence. The user identification data includes compressed image data. The signal receiving station is monitored by a supervisor who is able to intervene should the substance level be greater than a predetermined threshold, or should the user identification data no match with a reference user identification data.

  • Publication number: 20140037506
    Abstract: This nitrogen oxide concentration measurement device measures a nitrogen oxide concentration by shining light on a sensor produced by distributing a metal complex of porphyrin or a derivative thereof over a base material, and detecting the amount of light of a specific wavelength, said device comprising a light source that shines light at a nitrogen oxide concentration measurement sensor, a light detector that detects the amount of light of a specific wavelength out of all the light transmitted or reflected by the nitrogen oxide concentration measurement sensor, and a controller that corrects the detection result at the light detector so as to match the amount of light of a specific wavelength outputted from the light detector during exposure to a zero gas to a corrected value.

  • Patent number: 8597580
    Abstract: A handheld, small but accurate and reliable device for diagnostic NO measurements using a NO sensor, where the parameters governing the taking of the sample are different from the parameters optimal for the accuracy of said NO sensor I described. By temporarily storing a portion of the exhaled air, and feeding this to the sensor at a flow rate adapted to the NO sensor, the accuracy and sensitivity of a system/method involving NO sensors, in particular electrochemical NO sensors, can be increased. The method for diagnostic NO measurements comprises steps for controlling the inhalation of NO free air, as well as the exhalation, both by built-in means and by audible and/or visual feedback to the patient.

  • Patent number: 8560010
    Abstract: The present invention in several embodiments is a cell phone with breath analyzer that can store a preprogrammed list of phone numbers that are not to be called once a person's blood alcohol level has reached a specific point. This device could look similar to traditional cell phones. Within the mouth piece, or other place on or in the phone is a blood alcohol detector. As a person talks/breaths into the phone, their blood alcohol level will be measured. If the level is over a predetermined amount, a previously programmed list of phone numbers cannot be accessed. This unit may also have the capability to store a help list for the user. This list would allow the consumer to easily call a specific list of individuals if they were in need of a ride or other forms of assistance.

  • Patent number: 8551321
    Abstract: A process is provided for verifying an electrochemical substance in a gas sample. The process generates in an electrochemical sensor a measured electric value changing over time with a characteristic rising from a reference line to a maximum and again declining to the reference line. The percentage of the electrochemical substance in the gas sample is determined in an analysis circuit by setting a first interval and a second interval in the range of the characteristic after the maximum has been exceeded. The first interval includes the range of the characteristic in the vicinity of the maximum and the second interval includes the range of the maximum in the vicinity of the reference line. The electrochemical substance is determined by determining the ratio of the slopes of the first and second intervals and by comparison with a reference value of the ratio of the slopes of the first and second intervals.
