Abstract:
A flood warning system and method are described. The system obtains localized flood depth information and, based upon alert parameter information provided by registered users, creates personalized flood alerts for the registered users. The method uses ultrasound derived localized flood depth information and alert parameter information provided by registered users to provide personalized flood alerts to the registered users.
Abstract:
A spin stabilized aircraft may include a plurality of wings that passively spin stabilize the aircraft, causing the apparatus to move in a direction opposite that of a wind source. The aircraft may also include two or more propulsive arms that actively stabilize the aircraft in absence of wind or a decrease in altitude.
Abstract:
An unmanned aircraft system (UAS) making use of unmanned aerial vehicles (UAVs) for more than one task. The inventors discovered that an improved UAS could be provided by combining one or more of these three elements: (1) hot-swappable modular kits (e.g., a plurality of components useful in UAVs to perform particular user-selectable tasks); (2) an interconnection mechanism for each component with identification protocols that provides both a physical and a data connection; and (3) an intelligent system that interprets the identification protocols and determines the configuration for a selected task, error checking, airworthiness, and calibration. The system and associated methods for the task based drone configuration and verification reduces the possibility of task failure by an operator.
Abstract:
System and method for aiding the accuracy of airdrop missions by performing localized weather data collection in a column of air and then subsequently storing, decimating and forwarding the data to a remote location. A first aircraft flies to the geographic location of the desired airdrop, deploys an atmospheric conditions sensing dropsonde, collects the data from the dropsonde, stores that data, then transmits that data or a decimated subset of that data either once or any number of consecutive times, to a second aircraft located at a predetermined distance from the first aircraft.
Abstract:
A new fabrication method for nanovoids-imbedded bismuth telluride (Bi—Te) material with low dimensional (quantum-dots, quantum-wires, or quantum-wells) structure was conceived during the development of advanced thermoelectric (TE) materials. Bismuth telluride is currently the best-known candidate material for solid-state TE cooling devices because it possesses the highest TE figure of merit at room temperature. The innovative process described here allows nanometer-scale voids to be incorporated in Bi—Te material. The final nanovoid structure such as void size, size distribution, void location, etc. can be also controlled under various process conditions.
Abstract:
In general, a method includes receiving environmental information collected by an unmanned aerial vehicle (UAV), the environmental information being associated with one or more conditions of a data center, storing the environmental information on one or more memory devices that are accessible by the one or more computing devices, determining, based on the environmental information, that an event has occurred, and performing, by the one or more computing devices and based on determining that the event has occurred, one or more actions.
Abstract:
An apparatus for removing harmful gas components out of the earth's atmosphere is a free-flying autonomous lightweight aircraft with an onboard gas processing system including gas separation or extraction devices, and inlets and outlets connected to the devices. Solar cells and/or thermoelectric generators provided on the craft produce electrical energy to operate the individual devices. The system may include a cryogenic closed-loop circulation system that participates in liquefying the extracted gas components. The apparatus is preferably a lighter-than-air craft like a dirigible. A method of extracting harmful gas components from the atmosphere involves flying the apparatus at a prescribed altitude level and operating the gas processing system to remove the harmful gas component from the atmosphere, then returning the apparatus to earth to offload the liquefied stored harmful gas component.
Abstract:
The recoverable airborne instrument platform accurately determines its present position and uses this data to execute a predetermined flight plan and ultimately guide its descent to a predetermined landing site. This is accomplished by installing the instrument package payload in the aerodynamic exterior housing of the recoverable airborne instrument platform, which has a plurality of moveable control surfaces thereon to autonomously control the altitude, attitude and flight path of the recoverable airborne instrument platform. A navigation circuit contained within the aerodynamic housing determines the geographic location of the recoverable airborne instrument platform as well as the location of at least one predetermined recovery site. The determined position data is used to dynamically calculate a flight path which allows the guidance control circuit to both execute a predetermined flight plan and controllably descend the recoverable instrument platform to a selected predetermined recovery site. Upon arrival at the selected predetermined recovery site, the recoverable airborne instrument platform descends to a predetermined height over the selected predetermined recovery site and activates a parachute release mechanism to controllably descend to the selected predetermined recovery site.
