Abstract: Breath sensor calibration methods and apparatus are described herein where a breath sensor device may generally comprise a sampling unit having a housing configured to receive a sample breath from a user and a sensor positioned within the housing. A processor in electrical communication with the sensor may be configured to determine a dissipation time when the sensor is exposed to a near-constant concentration level of CO detected from the breath sample down to an ambient level of CO detected. The processor may also be configured to calculate a time constant based on the dissipation time and a reduction from the near-constant concentration level to the ambient level. Furthermore, the processor may also be configured to apply the time constant to a transient response of the sensor to account for drift in calibrating the sensor.

Abstract: Systems and methods for f assisting an individual with smoking cessation including generating a behavior summary and electronically providing a plurality of information to prepare the individual for smoking cessation.

Abstract: Breath sensor apparatus and methods of use are described herein where a flow control apparatus may generally comprise a sampling chamber defining a volume and one or more openings into the sampling chamber, at least one sensor in fluid communication with the sampling chamber, wherein the at least one sensor is configured to detect the analyte. The sampling chamber may also be configured to receive the breath sample into the sampling chamber and into contact with the at least one sensor via diffusion into the sampling chamber.

Abstract: Methods and systems of enhancing an electronic interaction between a behavioral-modification program and a user in the program by providing customized content specific to the user. The systems and methods allow for coach-counselor assistance to the individual-user or for automated content delivery.

Abstract: Devices, methods and systems are disclosed for assisting patients in behavioral modification and cessation programs aimed at terminating undesired behaviors such as smoking, alcohol use and others. Patient devices configured to be easily carried or worn including test units such as carbon monoxide blood level sensors with automated patient prompting for self-testing, analysis of test results and data logging are included in a networked system with a specifically designed treatment modality. Devices and methods disclosed are particularly suited to use in smoking cessation treatment and programs.
