Abstract: A radiation detector (100) includes an insulating substrate (110), which includes a material that undergoes a change in an electrical property when subjected to ionizing radiation. A conductive film (112) is disposed in relation to a surface of the substrate. The conductive film (112) has a resistance that is a function of a state of the electrical property. A resistance measuring device measures resistance across the conductive film (112). The resistance measured by the resistance measuring device indicates an amount of ionizing radiation to which the substrate (110) has been subjected. In a method of determining exposure to a type of radiation, a boron nitride substrate is exposed to a radiation environment. A resistance is measured across a conductive film disposed in relation to the boron nitride substrate. Radiation exposure is calculated as a function of the resistance.

Abstract: Methods, systems, and devices are disclosed for providing control of an unmanned aircraft (UA). A server may receive an indication from a UA that a transition from autonomous flight to pilot controlled flight is required while the UA is in autonomous flight. The server may select a pilot station for providing pilot controlled flight of the UA. Selecting a pilot station for providing pilot controlled flight of the UA may be based on a pilot criterion associated with the pilot station. A UA may detect a condition that requires a transition from autonomous flight to pilot controlled flight and establish a pilot criterion for pilot controlled flight based on the detected condition. The UA may send a request for a pilot that includes the pilot criterion and information about the condition.

The system may obtain a first control model for the first UAV type and a second control model for the target UAV. Pilot input commands processed through the first control model may be used to calculate movements of a virtual UAV of the type. The system may estimate physical movement of the target UAV similar to the first physical movement, and generate an override command for the target UAV using the second control model and the second physical movement. Control models may accommodate current conditions and pilot experience.

Abstract: Systems, methods, and devices of the various embodiments enable content controls to be implemented by a modem of a mobile device to ensure the controls are implemented regardless of whether an application processor of the mobile device has been rooted. In an embodiment, content controls may be implemented by a modem or list component separate from the application processor when in a subsidized content delivery mode. In an embodiment, content controls may include a whitelist and/or a blacklist of IP addresses that addresses of content requests may be compared against to filter authorized content from unauthorized content. Content requests for authorized content may be sent to the content location, while content requests for unauthorized content may be dropped. In the various embodiments, a whitelist and/or blacklist may be updated on demand and/or automatically by a whitelist/blacklist management portal.

Abstract: Graphene production using a continuous or pulsed laser beam focused on a substrate of graphite oxide in a significantly inert environment is disclosed. Laser-induced graphene features are characterized by a 2D-band in the Raman spectra. When the photons of the laser at a various frequencies and power levels beam impinge a graphite oxide foil for various amounts of time, a strip, divet, trench, or hole, having graphene at the bottom or sides is produced. The concentration of the graphite oxide and the laser beam may be adjusted so that the depth of the trench created is a certain depth less than the thickness of the foil. Additionally, in some embodiments, the evaporation of the water during the Hummers method is adjusted so that there remains interlaminar water in the graphite oxide foil. The presently disclosed subject matter may also be used in patterning using rastering or substrate motion.
