Disclosed herein are a non-invasive alcohol detection, identity management, access control, remote screening, and reporting systems.

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.

According to a present invention embodiment, at least one sensor detects one or more gases emanating from one or more pathogens in a wound that produce an infection. The at least one sensor includes sensing materials that change one or more properties in response to a presence of the one or more gases. At least one processor analyzes information from the at least one sensor to identify the one or more pathogens and determine a presence of the infection in the wound. The one or more pathogens are identified based on patterns of changes of the one or more properties indicating corresponding pathogens. The at least one sensor may be disposed within one of a wearable device, a portable device, and a wound dressing. In addition, a negative pressure source may be utilized to apply negative pressure to the wound to promote healing.

A method for context-aware self-calibration includes measuring for a plurality of time segments, at least one feature of at least one biosignal or each of at least one channel. Each biosignal is created in response to a user imagining an intended direction for each time segment. An object is moved along an actual decoded direction determined by an output of a decoder configured to correlate for each time segment the at least one feature to the intended direction. The decoder self-calibrates to minimize for each time segment, an error between the actual decoded direction, and the intended direction inferred subsequent to the respective time segment.

Various embodiments for providing remote delivery and monitoring of health care are provided. In one embodiment, an apparatus for providing unmanned medical care in remote areas to a patient is provided. A container is adapted for transport using a standardized shipping mechanism. The container is adapted to provide remote delivery of health care. In an additional embodiment, a portable apparatus for dermatological monitoring is provided. An imaging device is integrated into a housing. The imaging device is adapted to obtain a digital, high-resolution image of a patient. In still another embodiment, a portable apparatus for orthopedic monitoring of a patient is provided. A housing is adapted for one of positioning adjacent to and positioning within an orthopedic cast. A diagnostic biomedical device integrated into the housing. The diagnostic biomedical device is adapted for obtaining an orthopedic image of a portion of the patient treated with the orthopedic cast.

In order to determine the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state, a signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state. A mapping is used to improve accuracy of state determination, e.g. with a reference database.

Provided are concepts for generating an indicator of chronic obstructive pulmonary disease (COPD) in a subject. In particular, data from a plurality of sensors, including a pressure sensor, an airflow sensor, and a CO2 concentration sensor is captured from the breath of the subject received by a mouthpiece. The sensor data is then utilised by a processing unit to generate an indicator of COPD in the subject. By utilising airway pressure, airway flow rate and expiratory CO2 concentration data, an accurate indicator of the presence and/or stage of COPD may be obtained.

Technology for a wearable heart rate monitoring device is disclosed. The wearable heart rate monitoring device can include a heart rate sensor operable to collect sensor data, a modulator operable to generate a modulated signal that includes the sensor data, a housing configured to engage a body feature or surface in a manner that allows for heart rate detection, and a communication module configured to transmit the sensor data in the modulated signal to a mobile computing device via a wired connection that is power limited. The mobile computing device is typically configured to demodulate the modulated signal in order to extract the sensor data.

The various embodiments herein disclose a method and a system with a portable handheld diagnostic device for detecting and/or monitoring the prognosis of nerve impairment or diabetic peripheral neuropathy. The system provides a multi-parameter diabetic neuropathy-screening device to perform a combination of tactile threshold test, vibration threshold test, thermal threshold test and contactless skin-temperature measurement. The present invention provides a smartphone application that helps a user to operate/control the device, store and share the results. The smartphone application interacts with the hardware modules in the device and guides the user to perform the various tests. Further, the neuropathy diagnostic system provides a wireless feedback button that enables the subject to respond to various sensations during the course of the test.
