Abstract:
Methods and systems utilize combinations of gaseous concentration, contextual and location information provided by environmental sensors with physiological data provided by wearable sensors to personalize the parameters used in computational models for estimating metabolic parameters. This personalization allows for parameter estimates that better account for the subject-dependent nature of the relationship between heart rate and various metabolic features.

Abstract:
A system and method for sampling air at multiple locations in a controlled environment. The system and method includes automatic adjustment of mass flow rates and duration of vacuum connections (either via time elapsed or indirectly by volume) based on rates set by an operator. Additionally, the system and method enables users to monitor and control aspects of the system via network-connected devices. Additionally, the system enable a vacuum pump to be disconnected from power in response to a physical emergency button, a software-based emergency stop button available on network connected devices, and an automatic power disconnection in response to an abnormal mass flow reading that could potentially impact the vacuum pump.

Abstract:
An electronic discriminating device incorporating a non-contact electronic sensor array, a controller, and a signaling device that may indicate the presence of urine and/or bowel movement is disclosed. In particular, the electronic discriminating device can discriminate between an insult of urine only and an insult containing bowel movement. The device can then generate different alerts based on the type of insult. The electronic discriminating device may also emit a signal at or near the opening of an absorbent article or transmit the alert wirelessly to a radio, computer device, or smartphone.
