A Wearable Cardiac Defibrillator (WCD) system is configured to be worn by a patient who carries a mobile communication device. The mobile communication device has a user interface that is configured to enable the patient to enter wireless inputs. The WCD system includes a communication module that is configured to establish a local comlink with the mobile communication device. The WCD system also includes a tethered action unit that has a user interface configured to enable the patient to enter action inputs. The WCD system can perform some of its functions in response to the action inputs or to the wireless inputs. Since the wireless inputs can be provided from the mobile communication device instead of the action unit, the patient is less likely to attract attention when entering them, and thus exhibit better compliance.

An arrangement may include a first system provided for processing physiological data representative of a beating heart. The first system may be adapted to execute a process for using at least one pattern to detect a notable finding in the physiological data and for sending the notable finding to a second system. The second system may be adapted to execute a process for analyzing the notable finding, for determining at least one new pattern to send to the first system, and for sending the at least one new pattern to the first system. The at least one new pattern may also include a rule that includes a set of conditions and an action to perform if the set of conditions is met.

Aspects of the disclosure can provide a method and device for detecting EEG signals of a first person in proximity to the device. The device can include a non-contact EEG directional circuit having non-contact sensors, the non-contact EEG directional circuit being configured to detect the EEG signals produced by a brain of the first person without making contact with the first person. The device can further include a processor coupled to the non-contact EEG directional circuit that is configured to analyze the EEG signals to detect patterns in the EEG signals that correspond to a state of the first person in proximity to the non-contacting sensor and feedback device that is configured to provide a second person with an indication of the state of the first person in proximity to the non-contacting sensor.

provided is an automotive key device connected, in the form of a holder, to a mechanism of opening or shutting an automotive door or merged with the mechanism of opening or shutting the automotive door. The automotive key device includes an electrocardiogram (ECG) sensor having a first body signal electrode and a second body signal electrode and a contact terminal electrically connected to the ECG sensor. The contact terminal is configured to serve as a passage for electrical connection with devices within a vehicle. A steering wheel docking station and a system configured to include the steering wheel docking station and the automotive key device are also provided.

A device measuring an electrical activity of a heart and being wearable on a body part of a user. The device comprises a strap configurable to be fitted over the body part, and having an interior surface contacting the body part when worn by the user, and an exterior surface facing away from the body part. The device also includes a first sensor that is disposed on the interior surface. The first sensor is configurable to be in contact with the body part. The device also includes a clasp having a second sensor that is electrically insulated from the first sensor. The first sensor and the second sensor receive data indicative of an electrocardiogram (ECG) signal of the user when the clasp holding the strap over the body part contacts a different body part of the user.

An intelligent health strap. A detection and analysis method comprises: acquiring multiple groups of pulse data collected by multiple pulse sensors (11); and according to the multiple groups of pulse data, using a calculation method for analysis to obtain physical sign information (12). An intelligent health wrist strap and an intelligent health ankle strap having multiple pulse sensors are used for performing pulse monitoring and analysis, displaying multiple types of pulse physical sign information, and transmitting data to an external device, so that a user can conveniently monitor changes of individual physiological status, and the intelligent health wrist strap and the intelligent health ankle strap can provide massage and health-care for wrists and ankles.

A non-invasive sensor unit, such as a glove or pad, is adapted to be placed over the chest of an injured person who may be in need of CPR and/or AED. The sensor unit includes a plurality of electrodes for detecting one or more ECG voltages of the person. A controller processes the ECG voltages and displays them on a display, thereby enabling the user to assess whether CPR and/or AED is needed. The sensor unit is adapted to continue to provide ECG data while the user is applying chest compressions to the person. The sensor unit may include accelerometers for reducing artifacts from the ECG voltages that arise from the movement of the user while applying chest compressions. The electrodes are, in some embodiments, capacitive sensors that enable ECG voltages to be detected without requiring direct contact with the skin of the person.

Described herein are methods, apparatuses, and systems for heart monitoring of a patient. The heart monitoring system can be used to take an electrocardiogram (ECG) using only two electrodes. A handheld device can be used to sequentially measure the electrical signal between different positions on a patient's body. The electrical signals can be processed and analyzed to prepare an ECG for the patient, including a 12-lead ECG.

According to an aspect, there is provided a device for measuring a physiological characteristic of a first subject, the device comprising a first electrode for contacting a part of the body of the first subject; a second electrode for contacting a part of the body of a second subject; and a control unit for obtaining an electrocardiogram, ECG, signal using the electrodes and for processing the ECG signal to determine a measurement of a physiological characteristic of the first subject; wherein the signal comprises a first ECG signal component relating to the first subject and a second ECG signal component relating to the second subject, and the control unit is configured to process the ECG signal obtained from the electrodes to extract the first ECG signal component relating to the first subject and to process the first ECG signal component to determine a measurement of the physiological characteristic of the first subject.

An embodiment of the invention provides a wireless in-ear utility device that rests in the user's ear canal near the user's eardrum. The in-ear utility device may be configured in a variety of ways, including, but in no way limited to a smart in-ear utility device, a flexible personal sound amplification product, a personal music player, a “walkie-talkie” and the like.
