    Abstract: A system and method of protecting individuals from ionizing energy is provided. The system can determine a location of an individual with respect to a source of ionizing energy. Before the source emits ionizing energy, the system can determine patterns of ionizing energy expected to be generated by an expected emission from the source. The system can then determine if an individual is within a danger zone in which the individual is expected to receive a dose of ionizing energy above a predetermined amount. The system may also determine if an individual is outside of an optimal zone in which the individual is expected to receive less than a predetermined dose of ionizing energy without being unnecessarily distant from a working area. The system can provide a warning when an individual is within the danger or inefficient zones. Optionally, the system can prevent the source from emitting ionizing energy when an individual is within the danger zone.

  • Patent number: 10330804
    Abstract: A device for determining the location of a source of radiation, based on data acquired at a single orientation of the device without iteration or rotations. Embodiments may comprise two side detector panels flanking a shield layer, plus a front detector positioned orthogonally in front of the side detectors. The various detectors thereby have contrasting angular sensitivities, so that a predetermined angular correlation function can determine the sign and magnitude of the source angle according to the detection rates. Rapid detection and localization of nuclear and radiological weapon materials enables greatly improved inspection of cargo containers and personnel. Advanced detectors such as those disclosed herein will be needed in the coming decades to protect against clandestine weapon transport.

  • Patent number: 10310097
    Abstract: Apparatus, techniques and systems are described for facilitating identification of a target area during a probe-guided radio-localization surgical procedure. The described apparatus, techniques and systems can be used to implement a nuclear-uptake mode controller integrated into a probe to allow a user to instantly switch between multiple nuclear-uptake modes directly from the probe hand-piece. For example, a nuclear-uptake mode controller integrated into the probe can be used to instantly switch between a high-sensitivity nuclear-uptake mode and a high-resolution nuclear-uptake mode to effectively identify the target area in the presence of interfering nuclear signals by better matching the probe's nuclear detection parameters to a search task for that target area.

  • Patent number: 10306156
    Abstract: An image-capture device includes an enclosure, a lens arranged in a lens housing, an illumination source and an image sensor. The illumination source has separately energized light emitters adjacent to the lens housing. When a first light emitter is energized, light oscillating in a first orientation is directed away from the image-capture device. When a second light emitter is energized, light oscillating in a second orientation different from the first orientation is directed away from the image-capture device. Alternatively, an image-capture device includes image sensors, a lens and an illumination source. The illumination source directs emitted light away from the device in different orientations. Light reflected from a subject-of-interest is received in optical paths intersected by respective polarizers. Reflected light passing through a first polarizer is substantially orthogonal to reflected light passing through a second polarizer.

  • Patent number: 10262525
    Abstract: A networked visual and audible alarm apparatus with base station provides audible and visual alerts upon detection of smoke, carbon monoxide, and gas. The apparatus adapts to a light bulb socket to provide normal lighting when no event is detected. Multiple apparatuses are systematically disposed through different sections of a structure. Each apparatus independently emits an audible signal, dependent on the type of event detected in the respective section for the apparatus. Each alarm apparatus provides a colored high strobe light that illuminates at a color and intensity that varies, dependent on type of event detected. A microphone initiates the audible signal and the high strobe light upon detecting an audible signal from an adjacent alarm apparatus. Voice commands power off the alarming apparatus. A base station controls and monitors a network of apparatuses, and is programmable based on a code that is assigned to each alarm apparatus.
