Abstract:
A vacuum electronic device includes a multi-layer graphene grid that includes at least two layers of graphene, where the transmission of electrons through the multi-layer graphene grid can be tuned by varying the parameters of the vacuum electronic device such as the number of graphene layers, relative positions of the electrodes, voltage biases applied to the electrodes, and other device parameters.
Abstract:
Described embodiments include a system and a method. A system includes an evaluation circuit configured to determine a characteristic of an adverse circumstance present in a possible collision avoidance path of a vehicle. The system includes a rating circuit configured to assign a risk value to the possible collision avoidance path responsive to the determined characteristic of the adverse circumstance. The system includes an uncertainty assessment circuit configured to assign an uncertainty to the risk value. The system includes a threshold circuit configured to determine if the risk value of the possible collision avoidance path and the uncertainty in a combination meet a threshold criteria. The system includes a communication circuit configured to output the possible collision avoidance path as a selected collision avoidance path if the threshold criteria is met.
Abstract:
A vehicle may include a monitoring unit configured to determine a time-varying handling characteristic of the vehicle. The time-varying handling characteristic may include a characteristic of vehicle performance in executing maneuvers, a status of a vehicle component (e.g., tires, brakes, drivetrain, etc.), and/or the like. The time-varying handling characteristic may be transmitted to one or more nearby vehicles to improve the ability of manual operators and/or automatic-driving software of the nearby vehicles to predict the performance of the vehicle in executing maneuvers, to be aware of a failure (or likely failure) of a vehicle component, and/or the like. Record of the transmission of the time-varying handling characteristic and/or of any acknowledgements of receipt of the time-varying handling characteristic by the nearby vehicles may be logged to a persistent storage device.
Abstract:
A turbine blade includes a core element having a base portion, a tip portion, and an intermediate portion extending between the base portion and the tip portion. The intermediate portion includes a non-uniform cross-section and is a high-strength fiber material. The turbine blade further includes a shell disposed around the core element, and the volume between the core element and the shell forms a void.
Abstract:
A method for determining a property of an insurance policy includes receiving sensor data from a portable electronic device regarding a driving event involving a first vehicle. The sensor data is provided by the portable electronic device in response to a user initiating a command to report the driving event. The portable electronic device is external to the first vehicle. The method includes identifying, based on the sensor data, one or more of the first vehicle and a driver of the first vehicle. The method includes determining risk data associated with one or more of the first vehicle and the driver based on the driving event. The method further includes automatically updating an insurance property of an insurance policy associated with one or more of the first vehicle and the driver based on the risk data.
