Method for environmental analysis and control of spatial areas
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. |

Embeddable downhole probe
A downhole probe assembly is employed in a wellbore to mitigate the effects of hoop stress on the operation of the probe assembly. A shaped head is driven radially into the geologic formation surrounding the wellbore. A sensor and/or fluid ports may thereby be delivered to a radial depth in the geologic formation beyond a hoop stress regime associated with the wellbore. In this manner, analysis and fluid communication with the geologic formation may not be hindered by the hoop stress regime surrounding the wellbore. The probe assembly may be employed in microfracture tests in which fluid is injected into geologic formation through mechanical fractures created by the shaped heads extending through the hoop stress regime. The fluid injected through the hoop stress regime may more readily interact with the geologic formation, and subsequent analysis of the injected fluids may yield more relevant information about the geologic formation. |
