Then it communicates the angle to the user. An apparatus uses a sensor component to detect heat sources within a field of view. In response to an object being detected, a processing component determines whether the object is a heat source; and, if the object is a heat source, a feedback component alerts the user. One method includes receiving a notification that an object is in a field of view of a device and a temperature of the object. A determination is made as to whether the object is a person based on the temperature. In response to determining that the object is a person, a user is alerted.

The goal of the METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS as a continuation of “The Spatial Environmental Control Unit” is a method of logging multi-spectral, multi-pixel infrared radiation data of objects in a spatial area for the analysis and control of heat transfer dynamics in the spatial area that is responsive to feedback for controlling the thermal conditions in the spatial area. The METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS further makes the current norm of an “absolute” temperature control approach for thermal control and human comfort obsolete. Ambient environmental conditions and user preference variables makes the current, approach to thermal control time consuming, inaccurate and tedious. The Spatial Environmental Control Unit as one of our foundation patents disclosed the physical components make thermal control and analysis more responsive and user friendly. The METHOD FOR ENVIRONMENTAL ANALYSIS AND CONTROL OF SPATIAL AREAS makes the control and analysis of the thermal properties of the spatial area more intuitive by providing visual images on any compatible device simplifying the understanding of the dynamics of heat transfer in an environment. Tedium and frustration become understanding and empowerment. This method enables gaining knowledge and using tools for analysis, allowing a user to “redesign” his environment by correcting ambient conditions and improving the operation of the thermal conditioning equipment. The end result is a better thermal environment with higher energy efficiency. 1.

Methods for identifying and quantifying wrinkles in a composite structure by processing infrared image data. The intensity and first and second time derivatives thereof at a particular time can be displayed as thermography line profiles on a graph in which the horizontal axis represents the pixel number across the field of view of an infrared camera. The spatial derivatives of the foregoing thermography line profiles can also be calculated and displayed as a graph. The maximum amplitude (i.e., height) of an out-of-plane wrinkle can be determined using a correlation/calibration curve that is constructed by correlating infrared image data with optical measurement data. In addition, the wavelength and maximum amplitude of an in-plane wrinkle can be measured directly from the thermography line profiles. 1. A method for non-destructive inspection of composite structures , comprising:(a) developing a calibration curve for an infrared imaging system based on correlation of infrared image data and optical cross-section measurement data acquired from reference standards made of composite material, at least some of the reference standards having at least one wrinkle;(b) collecting infrared image data from a part made of composite material using the infrared imaging system after completion of step (a);(c) detecting the presence of an out-of-plane wrinkle in the part based on the infrared image data collected in step (b);(d) generating thermographic line profile data based on the infrared image data;(e) measuring a wavelength of the out-of-plane wrinkle in the part based on the thermographic line profile data generated in step (d); and(f) measuring an amplitude of the out-of-plane wrinkle in the part by applying the calibration curve to the thermographic line profile data generated in step (d).2.
