  • Patent number: 11979626
    Abstract: A system and method for operating includes providing a content for communication through a content distribution system having a broadcast mode and a unicast mode, determining a first number of user devices for receiving a communication of the content, determining a likelihood of consumption of the content by the first number of user devices, determining an available spectrum for communicating the content, determining a spectral efficiency for the unicast mode and the broadcast mode of the communication for each of the first number of user devices, selecting the broadcast mode or the unicast mode or both based on the first number of user devices, the likelihood of consumption of the content, the available spectrum and the spectral efficiency and communicating the content to the first number of user devices using the broadcast mode, the unicast mode or both based on selecting.

  • Publication number: 20220323793
    Abstract: The present invention provides strategies to use and control the delivery of ionizing radiation to carry out therapeutic and industrial irradiation treatments. The present invention uses partial pulse control, component selection, and/or component configuration strategies in order to accurately monitor and terminate irradiation. The strategies are particularly useful to control dosing in the high dose rate and short time scales associated with FLASH technology.

  • Patent number: 11285341
    Abstract: The present invention provides electron beam therapies with improved feedback control that delivers controlled and adjustable doses of electron beam radiation to variable shallow depths with little radiation exposure to both nearby tissues and tissues below the target. In order to control radiation to accurately penetrate to shallow depths and to allow the radiation to be adjusted to other depth settings in very small or even continuous increments, the present invention senses a plurality of different electron beam characteristics and then uses these to derive a composite characteristic, or analog, of the electron beam energy. The composite analog provides a strong correlation to energy that allows this precision. In another aspect, the present invention relates to implementing this feedback control by adjusting power levels used to establish the electron beam.

  • Patent number: 11115705
    Abstract: A method includes communicating first data to users for real time consumption by the users using a first portion of a system capacity of a system during a first time using a broadcast mode. The system capacity comprises the first portion of a broadcast transmission used for communicating the first data for real time consumption by the users and remnant capacity separate from the first portion of the broadcast transmission for non-real time consumption. The consumption occurs at a same time as when a user requests to consume the first data. The method includes communicating the first data through the communication system to a first device comprising an intermediate data storage device using the remnant capacity of the broadcast transmission during the first time. The first data is communicated using the remnant capacity of the broadcast transmission for non-real time consumption with a user application.

  • Patent number: 10472886
    Abstract: The invention is a roller shade tube assembly with a main housing having a lumen divided into two sections by an internal spring stop. The distal end of the main housing has a recessed mounting cavity coupleable to a motor. The proximal end of the main housing has one or more interlocking fingers. A spring inside the proximal lumen abuts the spring stop. An inner guide cylinder is coupled to slide inside the main housing against the spring and coupled to a lumen of an auxiliary housing that is movably coupled to the main housing. The distal end of the auxiliary housing includes one or more complementary interlocking fingers and a second recessed mounting cavity at its proximal end. Wall mounting brackets on each side of the tube assembly are configured to fit into the recessed mounting cavities. A shade fabric is coupled to the roller shade tube assembly.

  • Patent number: 8734399
    Abstract: An improved catheter is provided for insertion into a trachea, blood vessel, bladder or urinary tract of a patient. The self cleaning catheter can be easily inserted and removed from the patient without retained, solid components falling into a patient's trachea, blood vessels, bladder, or urinary tract when the catheter is removed from the patient. The self cleaning catheter has a flexible cylindrical sleeve on the exterior of a cylindrical member that can be withdrawn to the interior of the catheter prior to removal from the patient's body. Alternatively, the catheter has a design allowing an end of the catheter to fold inward on itself prior to removal from the patient's body.
