  • Spectral Discrimination using Wavelength-Shifting Fiber-Coupled Scintillation Detectors
    Publication number: 20190383953
    Abstract: Methods for discriminating among x-ray beams of distinct energy content. A first volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides that convert the scintillation light to light of a longer wavelength. An x-ray beam initially incident upon the first volume of scintillation medium and traversing the first volume is then incident on a second volume of scintillation medium. The first and second scintillation media may be separated by an absorber or one or more further volumes of scintillation medium, and may also have differential spectral sensitivities. Scintillation light from the first and second scintillation volumes is detected in respective detectors and processed to yield a measure of respective low energy and high-energy components of the incident x-ray beam.

  • Spectrally shaped x-ray inspection system
    Patent number: 6459761
    Abstract: A system and methods for non-invasive x-ray inspection of an enclosure in such a manner as to reduce the ambient radiation dose to below a specified level. A beam spectrally filtered to emphasize a high-energy component of penetrating radiation is interleaved, temporally, with a beam dominated by a low-energy component. Thus both lightly loaded and heavily loaded cargo may be inspected while limiting the ambient scattered radiation.

  • Coherent x-ray scatter inspection system with sidescatter and energy-resolved detection
    Patent number: 6442233
    Abstract: A system and method for inspecting an enclosure. A beam of x-rays is used for scanning the enclosure and for identifying areas of suspect material. The beam is subsequently coherently scattered off suspect materials, during the course of a single pass of the enclosure past the beam, for uniquely discriminating innocuous from contraband substances. One or more energy dispersive detectors measure radiation coherently scattered by an identified volume of suspect material. Absorption effects of the energy distribution of the coherently scattered radiation are compensated by means of a fiducial reference disposed between the interrogated object and the detectors.

    Publication number: 20020003867
    Abstract: Systems and methods capable of communication with a caller over a voice communication channel. The systems and methods allow a customer to employ a telephone to dial a telephone number that connects them with a central server. The server operates a voice recognition process that presents the customer with a computer-generated voice menu of options—for example, grocery delivery, takeout food, taxicabs, or information services. The caller would then say “food.” They would then say the location of their home after being prompted by the server system. After hearing a list of food options, the caller may select a choice by saying for example “Chinese”. The system would then present them with a list of restaurants to choose from. The caller would say the name of the restaurant of their choice, and the system would then route the call directly to the restaurant.

“A method is provided for acquiring and transmitting biometric data (e.g., vital signs) of a user, where the data is analyzed to determine whether the user is suffering from a viral infection, such as COVID-19. The method includes using a pulse oximeter to acquire at least pulse and blood oxygen saturation percentage, which is transmitted wirelessly to a smartphone. To ensure that the data is accurate, an accelerometer within the smartphone is used to measure movement of the smartphone and/or the user. Once accurate data is acquired, it is uploaded to the cloud (or host), where the data is used (alone or together with other vital signs) to determine whether the user is suffering from (or likely to suffer from) a viral infection, such as COVID-19. Depending on the specific requirements, the data, changes thereto, and/or the determination can be used to alert medical staff and take corresponding actions.” Link
