Abstract: A thermal imaging apparatus comprising: a thermal detector device (100) comprising an array of thermal sensing pixels (102) and signal processing circuitry (104) coupled to the detector device (100). The circuitry (104) supports a background identifier (110) and a pixel classifier (112), the background identifier (110) comprising a common intensity identifier (114) and an expected background intensity calculator (116). The background identifier (110) receives pixel measurement data captured by the detector device (100) in respect of pixels of the array (102) and the common intensity identifier (114) identifies a largest number of substantially the same pixel intensity values from the pixel measurement data. The expected background intensity calculator (116) uses the largest number of substantially the same pixel intensity values to generate a model of expected background intensity levels. The pixel classifier (112) uses the model to determine whether an intensity measurement by a pixel (118) of the array (102) corresponds to a background or an object in an image.

Abstract: According to one aspect, a method for remote monitoring of electrical equipment includes acquiring a set of data points, each data point representing a temperature associated with a piece of electrical equipment or a component thereof, assigning each data point to one or more groups of data points, and defining an alarm metric for each group. Each group's alarm metric may be defined independently of other group's metrics. The defined alarm metrics are used to determine the health of the electrical equipment. The data may be determined from virtual probes within an infrared sensor and/or received from RFID devices containing temperature sensor, which are attached to or near the equipment to be monitored, for example. The methods described herein do not require conversion of sensor data into temperature values, and thus obviate the need for expensive sensors and/or computationally demanding conversion, compensation, and calibration routines.

Abstract: Processes, algorithms and techniques are disclosed for detecting the presence of a source of at least one of heat, mass, momentum, energy, electrical field, and species in a system, such as, for identifying the presence of a heat source and its 3D location within a body part, and also to identify absence of a heat source within the body part. Multi-view thermal images are obtained of the body part and thermal and spatial information in different views are obtained. Iterative algorithms are developed to determine the presence of a heat source in the body part by employing the Physics-Informed Neural Network analyzer. Methods of generating a spatial-point-cloud and thermal-spatial-point-cloud are disclosed.

Abstract: Embodiments disclosed herein involve a wearable-based system that can help determine in a privacy-preserving manner whether a user is healthy (and thus poses low risk of contagiousness), and use determinations of this nature to grant passage through a doorway. In one embodiment, a wearable device takes measurements of a user comprising a photoplethysmogram signal (PPG signal) and a temperature measurement. A computer calculates a health score based on a difference between baseline measurements of the user, measured one or more days earlier, and more current measurements of the user. Additionally, the computer calculates an extent of similarity between characteristics of the PPG signal in the current measurements and characteristics of the PPG signal in the baseline measurements. The computer authorizes the user's passage through the doorway responsive to the health score reaching a first threshold and the extent of the similarity reaching a second threshold.
