Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.

Non-contact biological sensors 1, 2 that detect biological information of a person by electromagnetic waves are provided in a seat 10 on which the person sits. The biological sensors 1, 2 are disposed in the seat 10 at positions away from members A1, A2, A3 (22, 32) which are the members, from among the members that constitute the seat 10, that interfere with the passage of electromagnetic waves. The biological sensors each have a first sensor 100 and a second sensor 200 that emit electromagnetic waves of different frequencies towards the person, and the first sensor 100 is disposed adjacent to the second sensor 200. Due to this configuration, it becomes easier to accurately detect biological information.

The wearable article (200) comprises a sensing component. The electronics module (100) is removably coupled to the wearable article (200). The electronics module comprises a housing and a processor disposed within the housing (101). An interface element (121, 123) interfaces with the sensing component so as to receive signals from the sensing component and provide the same to the processor. A sensor (105) is disposed within the housing (101). The sensor (105) monitors a property of the environment external the electronics module (100) through the housing (101). The housing (101) is constructed such that the sensor (105) has line of sight through the housing (101).

Support device for supporting at least one body part of a user at least in portions, optionally completely, comprising a support body, which comprises at least one support region for supporting at least one body part of a user at least in portions, optionally completely.

Devices, systems, and methods herein relate to non-invasive patient monitoring for infection detection and infection resolution. These systems and methods may receive and measure patient biosignals to estimate an infection level of a patient. In some embodiments, a method may include the steps of receiving physiological data of a patient. An infection measure may be estimated based on the physiological data. An infection state of the patient may be detected based at least in part on the estimated infection measure.

This application discloses a method for controlling an electronic device to perform photoplethysmography detection. The method includes obtaining historical detection data of a photoplethysmography sensor, calculating a confidence of the historical detection data, determining, based on the calculated confidence of the historical detection data, whether a light source to be turned on by the photoplethysmography sensor in a next detection time segment includes a light source different from a light source turned on when the historical detection data is obtained, and determining that a photoelectric sensing element to be turned on in the next detection time segment is a photoelectric sensing element corresponding to the determined light source to be turned on.

Embodiments of the disclosure include a Radar system for detecting presence of a living thing. The radar system includes a transmitter/receiver module configured to emit radio signals to an environment surrounding the Radar system and to detect returned radio signals from the environment, and a large-movement detection sub-module configured to determine a large movement of the living thing based on the returned radio signals. The radar system also includes a micro-movement detection sub-module configured to determine a micro movement of the living thing based on the returned radio signals, and a breath and heartbeat detection sub-module configured to determine a breath or heartbeat of the living thing based on the returned radio signals. The radar system further includes a presence detection sub-module configured to determine the presence of the living thing based on determinations received from the corresponding detection sub-modules.

A system and method for positioning a sensor on a subject. In some embodiments, the system includes an instrument holder, the instrument holder being configured to be secured to a subject, and to hold an instrument temporarily.

Systems and methods for optimizing sensor pressure in blood pressure (BP) measurements using a wearable device are provided. An example method includes recording substantially synchronously photoplethysmogram (PPG) data using a PPG sensor and pressure data using at least one pressure sensor on a wearable device, the wearable device having the PPG sensor, and wherein the at least one pressure sensor is substantially located over a user wrist radial artery while an external force gradually applies and releases pressure a plurality of times to the wearable device, wherein the external force is applied to the radial artery. The PPG data and the pressure data is monitored as the PPG data changes in response to the external force being applied and released multiple times during a period. From the recorded PPG and pressure data, a set data us formed of PPG peak values and pressure values. A curve is fitted through the data set. From the curves apex value a MAP value is determined.
