There is provided a recognition system adaptable to a portable device or a wearable device. The recognition system senses a body heat using a thermal sensor, and performs functions such as the living body recognition, image denoising and body temperature prompting according to detected results.

Methods, systems, and devices for illness detection are described. A method may include identifying baseline temperature data associated with a user based on temperature data collected from the user via a wearable device throughout a first time interval. The method may include receiving additional temperature data collected via the wearable device throughout a second time interval, and inputting the baseline temperature data and the additional temperature data into a classifier. The method may include identifying a satisfaction of deviation criteria between the baseline temperature data and the additional temperature data, and causing a graphical user interface (GUI) of a user device to display an illness risk metric for the user based on the satisfaction of the deviation criteria, the illness risk metric associated with a relative probability that the user will transition from a healthy state to an unhealthy state.

An apparatus and method for sensing body temperature and wirelessly communicating measured data to at least one electronic device. The device includes a sensor device having a housing base, a housing cover releasably mountable on the housing base, and components for sensing body temperature and wirelessly communicating the measured temperature, including a temperature sensor, a power supply, a microprocessor, and a transmitter and receiver. The electronic device can include an application that communicates with the sensor device and provides a user interface.

Structures and techniques are provided for shaping or steering a light field for an optical biological parameter sensor such that the light is partially or wholly collimated and enters a person's skin at an oblique angle to the person's skin such that the light has a direction component oriented towards or away from a photodetector of the optical biological parameter sensor.

The present invention concerns a measurement system (10) of an individual's body temperature comprising: an archway (11) delimiting a passageway (9) for an individual;

a visible spectrum camera (6) fixed onto the archway (11) so that a field of view (31) of the visible spectrum camera (6) covers at least a portion of the passageway (9);

an infrared camera (12) fixed onto the archway (11) so that a field of view (32) of the infrared camera (12) covers all or part of the portion of the passageway (9); and

a processing unit (15) configured to identify the pixels corresponding to the individual's face in the visible image, to determine the corresponding pixels in the electronic image and to determine a maximum temperature value associated with the pixels corresponding to the face in order to deduce therefrom a body temperature of the individual.

A method for estimating human body temperature includes receiving, via a thermal camera, a thermal image captured of a real-world environment, the thermal image including thermal intensity values for each of a plurality of pixels of the thermal image. A position of a human face is identified within the thermal image, the human face corresponding to a human subject. An indication of a distance between the human subject and the thermal camera is received. Based on the distance, a distance correction factor is applied to one or more thermal intensity values of one or more pixels corresponding to the human face to give one or more distance-corrected thermal intensity values. Based on the one or more distance-corrected thermal intensity values an indication of a body temperature of the human subject is reported.

Apparatuses including features for predicting pressure wound formation are disclosed. A wheelchair apparatus includes a seat having a surface that contacts a subject when the subject is sitting in the wheelchair apparatus. The surface includes a thermochromic layer having one or more materials that cause the thermochromic layer to change to a first color upon application of thermal energy radiating from the subject that corresponds to a baseline body temperature and change to a second color that is different from the first color upon application of thermal energy radiating from the subject that corresponds to a temperature that exceeds a threshold difference from the baseline body temperature. The second color is indicative of a potential pressure wound.

A face shield includes a molded body portion configured to cover a wearer's eyes, nose, mouth, and chin. The body portion, which is secured to the wearer's ears by a pair of connector elements, includes at least one opening containing a replaceable filter. The face shield may part of a tracking system including multiple face shields, wherein each face shield includes a sensor that transmits data to a processor that in turn analyzes and interprets the data and transmits the results to a display device.

A contact-less passenger screening and identification system may include a temperature sensor, a blood oxygen saturation sensor, a cardiorespiratory sensor unit, one or more biometric sensor units, a communication circuitry, and one or more controllers. The one or more controllers may include one or more processors communicatively coupled to the temperature sensor, the cardiorespiratory sensor unit, and the one or more biometric sensor units. The one or more processors may be configured to execute a set of program instructions maintained in one or more memory units, where the set of program instructions is configured to cause the one or more processors to receive one or more signals, determine one or more physiological states of a subject, determine one or more identities of a subject, determine one or more business functions, and transmit one or more signals instructive of the one or more business functions.

A method of monitoring a patient's foot forms a thermogram of the sole of at least one foot of the patient, and determines whether the thermogram presents at least one of a plurality of prescribed patterns. The method also compares the thermogram against a prior thermogram of the same foot, and produces output information indicating the emergence of an ulcer on a given portion on the at least one foot as a function of 1) whether the thermogram is determined to present the at least one pattern, and 2) the comparison with the prior thermogram, which shows non-ulcerated tissue at the given location.
