A personal impact monitoring system is described herein comprising a monitoring station that receives impact events sent from personal impact monitors using a monitoring station receiver. The impact events which specify impact parameters associated with the impact events are stored in a data storage location associated with the monitoring station. Software operating on the operating station is configured to receive the impact events from the data storage location and to perform calculations based on the impact events to identify notable impact events.

Provided is a respiratory state estimating device including a pulse wave signal acquiring unit that acquires a pulse wave signal from a portion of a living subject, a pulse rate calculating unit that calculates a pulse rate of the living subject based on the pulse wave signal, and a respiratory state estimating unit that estimates a respiratory state of the living subject based on the pulse rate. Also, provided is a respiratory state estimating method including optically acquiring a pulse wave signal from a portion of a living subject, calculating a pulse rate of the living subject based on the pulse wave signal, estimating a respiratory state of the living subject from the pulse rate.

A system and device for cryoablation of tissue that is suitable for use within an MRI environment. The device may include an elongate body, a treatment element at the distal portion of the elongate body, and one or more pull fibers. The pull fibers may be composed of a non-ferromagnetic material, such as a polymer. Likewise, none of the other device components may be composed of a ferromagnetic material. The device may also include at least one fiber optic sensor. The elongate body distal portion may include a distal tip to which the pull fibers are directly coupled. Additionally or alternatively, the elongate body may include one or more pull fiber lumens configured to allow the pull fibers to deflect the distal portion when a pull force is exerted on the pull fibers.

A wearable medical screening device using electrical impedance tomogram and associated operation method. The wearable medical screening device includes electrodes, signal generator, and signal processor. The electrodes are arranged to be arranged on a body part of a wearer. The signal generator is arranged to provide a signal to at least one of the electrodes for transmission of a respective excitation signal to the body part of the wearer. The signal processor is arranged to process respective response signal received by at least one of the remaining electrodes as a result of the respective excitation signal, for determination of an electrical impedance tomogram for real-time preliminary medical screening of a disease associated with body part on which the wearable medical screening device is worn.

A portable apparatus for use by first responders comprises at least one receiver configured to receive input from at least one medical sensor; a display device configured to display first response guidance to a user; user input device configured to receive input from the user; and processing circuitry configured to process the input from the at least one medical sensor and the input from the user; select the first response guidance to be displayed to the user via the display device, the selecting of the first response guidance comprising: estimating a status of the human subject based on the input from the at least one sensor, and selecting at least one item of first response guidance from a plurality of stored items of first response guidance based on the estimated status; wherein the first response guidance comprises at least one action to be performed by the user.

Systems and methods to determine a risk factor related to dehydration and thermal stress of a subject are disclosed. Exemplary implementations may: generate output signals, by one or more sensors worn on a body of a subject, conveying information related to one or more of location of the subject, motion of the subject, temperature of the subject, cardiovascular parameters of the subject; store information related to the subject; obtain the output signals; determine in an ongoing manner, from the output signals, values of a water loss metric that correlates with estimated percentage of bodyweight of the subject lost in water; obtain heat index information for a contextual environment surrounding the subject; determine in an ongoing manner, from the output signals, values of an exertion metric that correlates with exertion of the subject due to work; and determine in an ongoing manner values for an aggregated risk factor of the subject.

Various embodiments provide systems and methods for detecting tampering with a monitoring device using biometric data.

The invention relates to a communication method for communicating monitoring data between a monitoring device (4) and processing means (6), wherein the monitoring device (4) is configured for receiving the monitoring data. The method comprises the steps of sending a byte frame to the processing means (6), storing the byte frame, ordering the byte frame by separating the frame into respiratory rate bytes, heart rate bytes and additional bytes, and repeating the previous steps with a predetermined frequency until the processing means have received a heart rate data set, a respiratory rate data set, and an additional data set. The processing means create heart rate information from the heart rate data set and create respiratory rate information from the respiratory rate data set and display them to a user.

A blood pressure monitor configured to removably mount to a cuff in a substantially symmetrical position with respect to a width of the cuff can include a housing defining an interior, a first port, and a second port. The first port can: secure to a first prong of the cuff when the cuff is mounted in a first orientation; receive and secure to a second prong of the cuff when the cuff is mounted in a second orientation; and enable fluid communication between the interior and at least one of a first fluid passage within the first prong and a second fluid passage within the second prong. The second port can: secure to the second prong of the cuff when the cuff is mounted in the first orientation; and receive and secure to the first prong of the cuff when the cuff is mounted in the second orientation.

Systems, devices, and methods described herein relate to multi-sensory presentation devices, including virtual reality (VR) devices, visual display devices, sound devices, haptic devices, and other forms of presentation devices, that are configured to present sensory elements, including visual and/or audio scenes, to a user. In some embodiments, one or more sensors including electroencephalography (EEG) sensors and a photoplethysmography (PPG) sensors, e.g., included in a brain-computer interface, can measure physiological data of a user to monitor a state of the user during the presentation of the visual and/or audio scenes. Such systems, devices, and methods can adapt one or more visual and/or audio scenes based on user physiological data, e.g., to control or manage the state of the user.
