  • Patent number: 10356654
    Abstract: User equipments (UEs) may be scheduled by determining relative priorities of data radio bearers (DRBs), each DRB associated with a respective UE. A limit is established dividing radio resources available for allocation in the cell during a scheduling period into at least a first limited portion and a second remaining portion. According to the determined relative priorities: a) up to the first limited portion of the radio resources are allocated to only the DRBs that have a guaranteed bit rate (GBR), and thereafter b) the second remaining portion of the radio resources are allocated to only the DRBs which have not been fully allocated from the first limited portion. Schedules indicating this allocation are transmitted to the respective UEs. In carrier aggregation where each carrier aggregated cells has a respective plurality of DRBs, relative priorities for each respective plurality of DRBs are determined for each carrier aggregated cell.

  • Publication number: 20190007916
    Abstract: A radio node may calculate one or more performance metrics based on measured satellite signals, which are associated with a global positioning system, or wireless signals that are associated with a cellular-telephone network. Then, the radio node may determine, based on the one or more performance metrics, whether the radio node is a synchronization master in a cluster of radio nodes. When the radio node is the synchronization master, the radio node may provide information intended for a computer specifying that the radio node is the synchronization master and the one or more performance metrics. In response, the radio node may receive a synchronization request associated with another radio node in the cluster. Furthermore, the radio node may provide the synchronization information intended for the other radio node, where the synchronization information specifies time, frequency, and phase synchronization for at least the cluster.

  • Publication number: 20180259654
    Abstract: An implantable dosimeter uses salt crystals such as NaCl or KCl, or other materials that vary in color as a function of incident, ionizing radiation. The color change of the salts may occur through the creation of F-centers, where electrons become trapped in crystal defects (e.g., halide vacancies) and absorb light at certain wavelengths. Vacancies in the salt crystals absorb photons at precise wavelengths. Thus, the change in color can be correlated to the integrated dose in an implantation site. The salt crystals may be optically coupled to optical fibers or the like for remote measurement of color using, e.g., a spectrometer and a computer system. In this manner, the dosage of ionizing radiation can be measured in vivo with a fault tolerant, passively integrating dosimeter.

  • Patent number: 10068740
    Abstract: An x-ray source for use in Phase Contrast Imaging is disclosed. In particular, the x-ray source includes a cathode array of individually controlled field-emission electron guns. The field emission guns include very small diameter tips capable of producing a narrow beam of electrons. Beams emitted from the cathode array are accelerated through an acceleration cavity and are directed to a transmission type anode, impinging on the anode to create a small spot size, typically less than five micrometers. The individually controllable electron guns can be selectively activated in patterns, which can be advantageously used in Phase Contrast Imaging.

  • Patent number: 10045752
    Abstract: Described here is a method for performing phase contrast imaging using an array of independently controllable x-ray sources. The array of x-ray sources can be controlled to produce a distinct spatial pattern of x-ray radiation and thus can be used to encode phase contrast signals without the need for a coded aperture. The lack of coded aperture increases the flexibility of the imaging method. For instance, because a fixed, coded aperture is not required, the angular resolution of the imaging technique can be increased as compared to coded-aperture imaging. Moreover, the lack of a radioopaque coded aperture increases the photon flux that reaches the subject, thereby increasing the attainable signal-to-noise ratio.

  • Patent number: 9800681
    Abstract: A network traffic monitoring system for redirecting network traffic between a client device and a cloud service includes a monitor proxy server configured as a network intermediary between the client device and the cloud service; and a published identity provider. The published identity provider is configured to receive a login request from a client device and to authenticate the client device at a federated identity provider. The published identity provider is configured to receive from the federated identity provider a redirect response including an identity assertion and a redirect web address to the cloud service. The published identity provider is configured to rewrite the redirect web address to the web address of the monitor proxy server. As a result, network traffic between the cloud service and the client device is routed through the monitor proxy server after user authentication using the published identity provider.
