An implantable electrical stimulating device and system provides for a remote determination of the identity of the person in whom the stimulating device is implanted. The stimulating device may be a pacemaker, a defibrillator, another medical device or a non-medical device. The bases for the remote identification are (1) the commingling of (A) biologic identification information of the person linked to the stimulating device, and (B) information pertaining to a physiologic parameter (e.g. heart rate information) of that person, and (2) the modulation of the physiologic parameter by external information. Embodiments of the invention in which the stimulating device is external to the person are possible. By utilizing the apparatus providing for the remote identification of a person plus stimulating device, one aspect of secure communication—that based on reliable mutual identification of each participant in a communication—is achieved.

A physical condition change detection device for detecting a change in physical condition of a subject includes a body-surface-side biological information detection unit that is configured to detect a variation in biological information obtained from a body surface of the subject and that is to face the body surface of the subject and an outside thermal variation detection unit that faces away from the body-surface-side biological information detection unit and that is configured to detect a thermal variation in an outside area separated from the body surface of the subject. The physical condition change detection device further includes a transmit unit configured to provide control to transmit detection data of the body-surface-side biological information detection unit and the outside thermal variation detection unit to the outside at every given time.

An ear-wearable device includes a photoplethysmography (PPG) sensor. One or more processors of the ear-wearable device are configured to determine, based on sample values of a PPG signal generated by the PPG sensor, whether a user of the ear-wearable device has fallen.

Various embodiments relate to a first-aid kit including at least one first aid item; and a wearable device configured to be worn by a user and including: a communications interface for communicating with a mobile device of the user; a sensor for obtaining vitals data when the wearable device is worn by the user; a processor configured to transmit vitals data to a mobile phone of the user via the communications interface wherein the first aid kit includes a means for causing instructions for processing the vitals data to be loaded onto the mobile device. In some such embodiments, the means for causing instructions to be loaded includes: a memory storing contents including at least one of: the instructions for processing the vitals, and a resource identifier that points to the instructions for processing the vitals at an application download server, wherein the contents are transmitted to the mobile device.

In embodiments, a wearable medical system (WMS) for an ambulatory patient, which can be a wearable cardioverter defibrillator (WCD) system, analyzes the patient's ECG signal to generate a detection outcome. The WMS also has an ambulatory user interface that outputs a human-visible indication. A programming device, such as a PC, a tablet, etc., establishes a communication link with the WMS during an in-person session with the patient. The programming device may include a programming screen that reproduces the human-visible indication in real time. An advantage can be that the person programming the WMS need not strain to look also at the ambulatory user interface at the time they are looking at the programming device. Another advantage can be that the patient will recognize that he or she is better protected, and have their confidence in the WMS increased, and therefore better comply with wearing the WMS as required.

The present disclosure discloses a device, system and method for testing cardiac exercise functions. Chronotropic Competence Indices (CCIs) are proposed to quantitatively describe the adaptation capability of cardiopulmonary system in response to exercise intensity variation in terms of heart rate changes, and thereby describes the dynamic process of the heart in the body metabolic process. The present disclosure discloses a device which measures the CCIs in real time by using the wearable technology, and referred to as Cardiac Exercise Test (CET). Compared with the Cardiopulmonary Exercise Testing (CPX) and parameters measured by the CPX such as a maximum oxygen uptake, the CCIs have clear clinical meanings and specific normal reference values; and the CET reduces the risk of the test. It is simple to use, and can be used anytime anywhere. It is of great importance in wide clinical applications, and is of great significance in prevention and rehabilitation of cardiopulmonary disease.

A vehicular system includes a wearable device and a computing device. The wearable device is configured to be worn by an operator of a vehicle. The wearable device includes a sensor configured to measure a physiological state of the operator. The wearable device is configured to output physiological data indicative of the physiological state of the operator or operator health alert data indicative of a determined health problem associated with the operator. The computing device includes a processor configured to receive the physiological data associated with the operator or the operator health alert data from the wearable device and to determine whether the operator is experiencing a health problem based on the physiological data or the operator health alert data.

Various embodiments disclosed herein relate to wearable devices for capturing biometric, motion, and other wearer measurements and subsequently providing feedback to the user. Various methods and systems described herein include one or more of the following: storing, in a memory, a record specifying applicability criteria, a resource identifier, and a server identifier; obtaining, by a processor in communication with the memory, a user metric captured by the wearable device; comparing the user metric to the applicability criteria to determine that the record is currently applicable; transmitting the resource identifier to the server associated with the server identifier; receiving, in response to transmitting the resource identifier, data for display to a user wearing the wearable device; and effecting display of the data to the user.

For generating a breathing alert is disclosed, a method receives a video stream of a subject. The method further estimates a breathing signal from the video stream. The method determines one of a large-scale motion and/or a breathing event of the subject based on the breathing signal. The method generates an alert if both no breathing event is identified and no large-scale motion of the subject is identified within an event time interval.

The invention is a method for detection is an individual has fallen down using data from a hardware motion sensor, and moreover, integrating contextual and environmental data to improve accuracy and reduce false positives. Such a sensor could be embedded into a smartwatch, mobile phone, or wearable device, rendering this method suitable for tracking the health and wellness of individuals of limited independence such as the elderly.
