Shear force and pressure on a structure are simultaneously monitored using signals received from sensors with antennas on the structure. For example, sensors and systems for monitoring shear force and pressure have applications including ulcer prevention associated with structures including shoes, prosthetics, wheel-chairs, and beds of bed-bound patients.

A catheter adapted for mapping and/or ablation in the atria has a basket-shaped electrode array with two or more location sensors with a deflectable expander. The catheter comprises a catheter body, a basket electrode assembly at a distal end of the catheter body, and a control handle at a proximal end of the catheter body. The basket electrode assembly has a plurality of electrode-carrying spines and an expander that is adapted for longitudinal movement relative to the catheter body for expanding and collapsing the assembly via a proximal end portion extending past the control handle that can be pushed or pulled by a user. The expander is also adapted for deflection in responsive to an actuator on the control handle that allows a user to control at least one puller wire extending through the catheter body and the expander.

Methods for monitoring a fetus employ a mobile computing device. A method of monitoring a fetus includes generating a first preprocessed acoustic signal via amplification of a first acoustic signal. The first preprocessed acoustic signal is processed by a mobile computing device to extract one or more of a fetal heart sound, a fetal heartbeat rate, or a fetal heartbeat acoustic intensity.

Disclosed is a method of detecting a smoking behavior based on an acceleration sensor. A method of detecting a smoking behavior based on an acceleration sensor according to an exemplary embodiment of the present disclosure includes: calculating a wrist acceleration variation value which is a variation value of gravitational acceleration applied based on a gravitational direction with respect to a user's wrist in accordance with a motion of the user's wrist by using a three-axis acceleration sensor worn on the user's wrist; converting the wrist acceleration variation value into a wrist angle variation value which is a variation value of a wrist angle that indicates an angle to the user's wrist based on the gravitational direction; comparing at least one template signal made by modeling the variation value of the user's wrist angle corresponding to a smoking behavior with the wrist angle variation value; and detecting the user's smoking behavior based on the comparison result.

The present disclosure relates to noninvasive methods, devices, and systems for measuring various blood constituents or analytes, such as glucose. In an embodiment, a light source comprises LEDs and super-luminescent LEDs. The light source emits light at at least wavelengths of about 1610 nm, about 1640 nm, and about 1665 nm. In an embodiment, the detector comprises a plurality of photodetectors arranged in a special geometry comprising one of a substantially linear substantially equal spaced geometry, a substantially linear substantially non-equal spaced geometry, and a substantially grid geometry.

A three-dimensional, head mounted microphone array is employed to isolate and analyze intracranial sound sources such as may provide for objective tinnitus. The microphone array allows a region of interest within the patient's head to be isolated for the detection of sounds and allows episodic sounds to be automatically identified as to location. An interactive display allows a better understanding of sound locations and the extracted sounds can be analyzed with respect to a library of sounds linked to particular locations and diagnoses.
