Abstract: Airway management virtual reality (VR) training systems and methods are provided, which use relatively simple and passive physical patient models to train users in performing airway management procedures. Patient models may include a respiratory tract, a moveable head and an openable jaw, which are anatomically realistic; and electromagnetic sensors that measure the movements of parts of the physical model and movement of tools used to handle the model. The parameters of the medical procedure being performed are sensed, tracked and displayed, providing the trainee with a continuous, detailed and coherent VR representation of the training situation in a realistic scene, utilizing and modifying a sensors' hierarchy to focus the VR representation on key features of the training and to yield interactivity of the VR patient and assessment of the trainee's performance.

Abstract: A detector assembly includes a hollow body in which a printed circuit board, a resistive plate, a drilled board, a drift volume, and a cathode are disposed. A surface of the printed circuit board exposed to the resistive plate includes printed circuit lines for measuring first and second coordinates of a charge event. The hollow body can include a sealable opening to remove contaminants outgassed from one or more components of the detector assembly and to fill the hollow body with an operational gas. The sealable opening can be fluidly coupled to a gas and vacuum system to reduce the concentration of the outgassed contaminants.

Abstract: A method for underground exploration using cosmic rays muons, the method comprises: detecting cosmic ray muons by sensing ionizing events that initiate within spaces of one or more gas amplification detectors of a system that is positioned within an underground space; and limiting a flow of gas within the spaces of the one or more gas amplification detectors.

Abstract: Methods of detecting high atomic weight materials in a volume such as a truck or cargo container are disclosed. The volume is scanned with an X-ray imaging system and a muon detection system. Using the output data of the muon detection system, the exit momentum and incoming and outgoing tracks of each muon are reconstructed. A muon scattering statistical model is calculated using the muon exit momentum and the incoming and outgoing tracks of the muon. A most likely scattering density map is determined according to the muon-scattering statistical model and an X-ray statistical model. A visual representation of the most likely scattering density map is displayed.

Abstract: A detector assembly includes an insulating substrate, a printed circuit board, a resistive, plate, a drilled board, a drift volume, and a cathode. A surface of the printed circuit board exposed to the resistive plate includes printed circuit lines for measuring first and second coordinates of a charge event. A mechanical assembly applies a force between the insulating substrate and the resistive a plate to form an electrical contact between the printed circuit lines on the printed circuit board and the resistive plate without the use of an electrical adhesive.
