A system for controlling blood pressure includes a wearable interface having an internal contact surface, the wearable interface configured to at least partially encircle a first portion of a first limb of a subject, a sensing module carried by the wearable interface and configured to determine at least a change in blood pressure of the first limb of the subject, and an energy application module carried by the wearable interface and configured to apply energy of two or more types to the first limb of the subject.

A diaphragm-based sensor includes a deflectable diaphragm, a base layer opposite the diaphragm, and a corrugated wall extending between the diaphragm and the base layer. The diaphragm is suspended over a cavity enclosed by the diaphragm, the base layer and the corrugated wall. The diaphragm includes a first electrode and the base layer includes a second electrode such that a capacitance between the first and second electrodes changes when the diaphragm is deflected relative to the cavity.

Introduced are a bed device system and methods for: gathering human biological signals, such as heart rate, breathing rate, or temperature; analyzing the gathered human biological signals; and controlling the bed device system, e.g., a temperature of the bed device, based on the analysis.

An electronic system for a surgical instrument is disclosed. The electronic system comprises a main power supply circuit configured to supply electrical power to a primary circuit. A supplementary power supply circuit configured to supply electrical power to a secondary circuit. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. The supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit. The supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.

A wearable sensor device includes a temperature and humidity sensor that measures ambient environmental information around a living body, a snap button connected to a bioelectrode, a biological information measurement unit that measures biological information, an inertial sensor that measures inertial information, a calculation unit that calculates a biological feature amount based on the biological information and calculates an inertial feature amount based on the inertial information, and a wireless communication unit that transmits the biological information, the inertial information, the biological feature amount, the inertial feature amount, and the environmental information to the outside.

Disclosed herein are devices, methods and systems for monitoring and detection of pressure on a part of a body of a user. In an embodiment, a device includes a substrate having a contact surface for contacting a user, one or more sacs associated with the contact surface of the substrate, and one or more sensors in communication with the one or more sacs, the one or more sensors adapted to measure changes in pressure in the one or more sacs. The sacs contain a fluidic material configured to transmit pressure. The fluidic material is further configured to be shock-absorbing and pressure-relieving such that the fluidic material is displaceable by an action of the user contacting the contact surface causing the pressure in the fluidic material to be redistributed.

A method and system for indicating a breathing pattern is disclosed. The system comprises a plurality of smart wearable devices, a plurality of mobile devices, an application server and a database. The plurality of smart wearable devices is either connected to the mobile devices or directly connected to the application server. The database is connected to the application server to store the data transmitted by the smart wearable device or the mobile device. The plurality of smart wearable devices is capable of monitoring the health index and identifying the variation in health conditions of the user, in real-time and activating a suitable breathing pattern to normalize such medical condition.

A contact sensor and system for incorporation within clothing and other wearable items to monitor activity at a body surface. The sensor includes a contact membrane having a body surface contacting area and one or more base layers of knitted fabric. The base layer(s) is thicker over an area congruent with the body surface contacting area of the contact membrane. As a result, the contact membrane is urged into the forming of a raised outer surface for projection against a body surface.

A garment with safety features is described. The garment includes a covering configured to cover at least a portion of a wearer. The covering extends between a first location and a second location spaced apart from the first location. The garment includes a flexible panel with the covering overlaying the flexible panel. The flexible panel is attached to the covering at the first location and the second location. The covering comprises excess material between the first location and the second location, the excess material being configured to accommodate stretching of the flexible panel.

An apparatus for energy expenditure estimation includes a heart rate sensor for producing a heart rate value indicative of a heart rate of an individual, a heat-flux sensor for producing a heat-flux value indicative of a heat-flux flowing through a measurement area on the skin of the individual, and a processing system communicatively connected to the heart rate sensor and the heat-flux sensor. The processing system is configured to produce an estimate of the energy expenditure based on the heart rate value and the heat-flux value. The use of the heat-flux value improves the accuracy of the estimation especially during low-intensity exercise and rest, when both heart rate and acceleration values often fail to provide information meaningful enough for energy expenditure estimation.
