Abstract: A semiconductor device includes a first field effect transistor (FET) located on a substrate; and a second FET located on the substrate, the second FET comprising a first buried oxide (BOX) region located underneath a channel region of the second FET, wherein the first BOX region of the second FET is configured to cause the second FET to have a higher radiation sensitivity that the first FET.

Abstract: A radiation exposure system having a beam source is provided. The system further includes a variable thickness degrader, positioned between the beam source and an object to be exposed, for providing varying degrees of degradation to a radiation beam emitted from the beam source onto the object. The system also includes a set of detectors, positioned between the variable thickness degrader and the object, for receiving and measuring only a portion of the radiation beam remaining after the degradation of the radiation beam by the variable thickness degrader.

Abstract: An integrated radiation sensor for detecting the presence of an environmental material and/or condition includes a sensing structure and first and second lateral bipolar junction transistors (BJTs) having opposite polarities. The first lateral BJT has a base that is electrically coupled to the sensing structure and is configured to generate an output signal indicative of a change in stored charge in the sensing structure. The second lateral BJT is configured to amplify the output signal of the first bipolar junction transistor. The first and second lateral BJTs, the sensing structure, and the substrate on which they are formed comprise a monolithic structure.

Abstract: A monolithic integrated radiation sensor or dosimeter (and manufacturing method) to detect environmental radiation (e.g ionizing radiation, neutrons) includes a sensing structure (e.g SOI insulating buried oxide layer, BOX 22) and first and second lateral bipolar junction transistors (BJT, LBJT) of opposite polarity (i.e NPN and PNP BJT devices). The first lateral BJT 30 (Q1) acts as the radiation sensor; its base 33 electrically coupled to the sensing structure 22 (e.g BOX 22 or upper oxide 132 fig 5) and produces an output signal as the stored charge changes within sensing structure. The second lateral BJT acts as an amplifier whilst the polarity is such that the ionizing effect is minimized. At least one of the lateral BJTs has an inverted (base) configuration (122 fig 2). The base of the second LBJT amplifier is electrically connected to an output of the first sensing lateral BJT (e.g base/collector). The doping concentration of the base of the second LBJT is higher (e.g by a factor of ten) than that of the base. The output of the first sensing BJT is configured to pass current directly into the base of the second lateral BJT, and the output (collector) of the second BJT corresponds to the output of the second amplifying BJT device. The integrated radiation sensor may include a neutron conversion layer within the buried oxide layer or an oxide layer on top of the LBJT sensor base.

Abstract: A method for predictively reconstructing a physical event using augmented reality, comprising: identifying relative states of objects located in a physical area by using video analysis to analyze collected video feeds from the physical event before and after a physical event involving at least one of the objects, creating a knowledge corpus including the video analysis and the collected video feeds associated with the physical event and historical information, and capturing data, by a computing device, of the physical event area, identifying possible precursor events based on the captured data and the knowledge corpus, and generating a virtual reconstruction of the physical event using the possible precursor events, displaying, by the computer device, the generated virtual reconstruction of the predicted physical event, wherein the displayed virtual reconstruction of the predicted physical event overlays an image of the physical event area.
