An apparatus for estimating a core body temperature of an object is provided. According to one embodiment, the apparatus includes a plurality of sensors configured to obtain data from an object and a processor configured to obtain a surface temperature, a heat flux, a skin blood flow rate, and a blood flow velocity by using the data obtained from the plurality of sensors, obtain a skin thermal conductivity based on the skin blood flow rate, and estimate a core body temperature of the object based on the surface temperature, the heat flux, the skin thermal conductivity, and the blood flow velocity of the object.

An alignment tool helps a patient position a chest-worn sensor device, such as a device for daily at-home monitoring of cardiopulmonary health conditions. The alignment tool includes a sensor connector that engages with the sensor device and a strap. The strap includes a first portion that has a protruding region sized to fit into the patient's suprasternal notch. The strap includes a second portion that engages with the sensor connector. The sensor connector and the first portion of the strap with the suprasternal notch protrusion are separated by a configurable length. A healthcare provider may set the length based on the distance between the patient's suprasternal notch and heart.

A method for dynamically determining a separation distance in which thermal images of a space are received that indicate a count and location of users within the space, temperature of the users within the space are received along with acoustic data from the users within the space, which is filtered to include specific symptom-related sounds and discard other sounds. The one or more processors generate a probability of a contagious infection of users within the space at a location determined by the thermal images, based on correlating the temperature and the acoustic data associated with the users within the space. A separation distance from the users within the space is calculated, based on the locations and the probabilities of infection of the users within the space, and a notification corresponding to the calculated separation distance is delivered to a protected user.

The present invention provides transseptal puncture devices configured to access structures on the left side of the heart from the right side of the heart without requiring open-heart surgery. The devices have adjustable stiffness to enter the vasculature in a flexible, atraumatic fashion, then become rigid once in place to provide a stable platform for penetration of the fossa ovalis. The devices are further configured to controllably and stably extend a needle to puncture the FO. The devices include an indwelling blunt stylus that can extend perpendicularly from the device to increase the accuracy of placement near the fossa ovalis.

Devices and methods for simultaneously measuring, in real time: 1) volumetric changes of a mammalian breast due to milk production and output, and 2) breast temperature, are provided. The devices are generally sensors which can be disposed within a wearable garment such as a bra.

Various non-invasive sensors are adapted to be placed on a surface of an object having a volume with an internal region. The internal region of the object has internal properties indicated by corresponding internal parameters and an internal temperature distribution that is a function of the internal parameters and surface thermal signals. Each non-invasive sensor includes a heat flux sensor having one or more heat flux sensor output terminals to provide a measured heat transfer signal for the surface of the object, and a temperature sensor having one or more temperature sensor output terminals to provide a measured temperature signal for the surface of the object. Systems including one or more of the sensors perform non-invasive sensing of the object including accurate and rapid determination of an internal temperature distribution of the internal region of the object as well as one or more other internal properties of the object.

A body temperature measurement method applied to a wrist wearable device includes, when a body temperature of a user is measured, measuring a first temperature at a forehead of the user using a temperature sensor, and measuring a second temperature at a wrist of the user is using a second temperature sensor at a relatively close time. Through calculation, a third temperature associated with the first temperature is displayed on a display. A fourth temperature at the wrist is then measured using the second temperature sensor. When the fourth temperature is the same as the second temperature, the third temperature is displayed on the display according to the foregoing relationship.

Certain embodiments of the present disclosure relate to a monitoring device that includes a housing, contactless sensors coupled to the housing, and a processing device disposed in the housing. In at least one embodiment, the monitoring device is configured to measure pulse wave velocity in a subject.

A ring-shaped earphone may be configured to be worn in an ear. When not worn in the ear, the ring-shaped earphone may be conveniently stored on a finger. In one example, the ring-shaped earphone may include a ring-shaped body defined by an outer cylindrical surface and an inner cylindrical surface. The earphone may include a speaker within the ring-shaped body. The speaker may be configured to project sound through a speaker opening in the outer cylindrical surface. The earphone may include a microphone within the housing. The microphone may be configured to receive sound through a microphone opening in the inner cylindrical surface.

An in vivo temperature control system has a monitor for the internal temperature of a biological organ such as the esophagus, and for directly controls the temperature in the organ side depending on the monitoring. The in vivo temperature control system includes: a catheter insertable into a living body; a temperature probe containing a temperature sensor, the probe being insertable into the catheter; a liquid storage section for storing a temperature-controlled liquid; a pump for supplying the liquid from the liquid storage section to the catheter; and a control section for controlling driving of the pump based on a signal detected from the temperature probe; wherein the control section controls the pump when the signal has reached a preset threshold, and the pump is driven such that the liquid in the liquid storage section is released to the outside through the catheter.
