摘要： A portable radioactive-material detection system capable of detecting radioactive sources moving at high speeds. The system has at least one radiation detector capable of detecting gamma-radiation and coupled to an MCA capable of collecting spectral data in very small time bins of less than about 150 msec. A computer processor is connected to the MCA for determining from the spectral data if a triggering event has occurred. Spectral data is stored on a data storage device, and a power source supplies power to the detection system. Various configurations of the detection system may be adaptably arranged for various radiation detection scenarios. In a preferred embodiment, the computer processor operates as a server which receives spectral data from other networked detection systems, and communicates the collected data to a central data reporting system.

摘要： A method and system using the Sequential Probability Ratio Test to enhance the detection of an elevated level of radiation, by determining whether a set of observations are consistent with a specified model within a given bounds of statistical significance. In particular, the SPRT is used in the present invention to maximize the range of detection, by providing processing mechanisms for estimating the dynamic background radiation, adjusting the models to reflect the amount of background knowledge at the current point in time, analyzing the current sample using the models to determine statistical significance, and determining when the sample has returned to the expected background conditions.

摘要： Embodiments of techniques and technologies to verify the interference fit of fasteners are disclosed. In one embodiment, a transducer is positioned to transmit a shear ultrasonic signal through a region of a fastener which is subject to stress when the fastener experiences an interference fit. The shear ultrasonic signal is transmitted through a region of the fastener subject to the stress. As the transmitted ultrasonic signal encounters the region, it is mode converted corresponding to a degree of interference which the fastener is experiencing. A return ultrasonic signal from the fastener is received with the transducer. From the return ultrasonic signal, a processor determines the degree of interference fit which the fastener is experience and outputs an indication of the same.

摘要： Embodiments of techniques to verify the interference fit of fasteners are disclosed. In one embodiment, a method includes aligning a probe proximate a fastener, the fastener being disposed within a material. A dynamic stress signal is generated from the probe using a low frequency transducer, and the dynamic stress signal is interrogated after it passes between the fastener and the material. An interference fit is then determined based on the interrogated dynamic stress signal.

摘要： A latching system for removably securing a first structure to a second structure. The system includes at least one magnetically permeable latch bar pivotally coupled to the first structure, and a biasing spring that pivots the latch bar to a latched position within a recess in the second structure, thereby securing the first structure to the second structure. Additionally, the system includes an unlatching tool that includes an embedded magnetized bar that generates a magnetic field around the unlatching tool. The unlatching tool can be used to pivot the latch bar to an unlatched position by placing the unlatching tool in close proximity to the latch bar such that the magnetic field exerts a rotational force on the latch bar, thereby pivoting the latch bar to the unlatched position.
