Embodiment Construction

[0042]A "thermal camera" refers herein to a non-contact device that measures electromagnetic radiation with wavelengths longer than 2500 nanometers (nm) without touching its region of interest (ROI). A thermal camera may contain one sensing element (pixel), also referred to herein as a "sensing pixel," "pixel," and / or a focal plane array (FPA), or multiple sensing elements. Thermal cameras may be based on uncooled thermal sensors such as thermopile sensors, microbolometer sensors (where microbolometer refers to any type of bolometer sensor and its equivalent), pyroelectric sensors or ferroelectric sensors .

[0043] of the form "Thermal Measurement of ROI" (often denoted as TH ROI or some variation thereof) refers to at least one of the following: (i) temperature measurement of the ROI (T ROI ), such as when using thermopile or microbolometer sensors, and (ii) the temperature change measurement of the ROI (ΔT ROI ), such as when using thermoelectric sensors or when temperat...

Abstract

Described herein are various embodiments of wearable systems that collect thermal measurements related to respiration and / or brain activity. The systems may optionally include a frame that is worn ona user's head, and at least one non-contact thermal camera that is physically coupled to the frame and located close to the user's face. In one embodiment, each thermal camera takes thermal measurements of at least one of: a portion of the right side of the user's upper lip, a portion of the left side of the user's upper lip, and a portion of the user's mouth. The thermal measurements used by a computer to calculate breathing related parameters, such as breathing rate, an extent to which the breathing was done through the mouth / nostrils, and ratio between exhaling and inhaling durations. In another embodiment, a thermal camera takes measurements of the forehead, which are indicative of brain activity of the user.
