Abstract: A method is provided. An unmanned aerial vehicle (UAV) is operated. A position of the UAV is determined while in flight, and a nonce is generated. A Merkel root is generated based at least in part on a timestamp and the position of the UAV. A current block is calculated based at least in part on a previous block, the Merkel root, and the nonce, and the current block, the timestamp, the nonce, the prior block, and the position of the UAV are transmitted.

Abstract: A vehicle controllable by an autonomous mode and an alternate mode is provided. The vehicle includes a body, one or more lights positioned on the body of the vehicle; and a processor. The processor is operable to be in signal communication with the one or more lights and the vehicle. The processor is configured to: receive an initial signal that the vehicle is being controlled by the autonomous mode or the alternate mode; actuate, when the vehicle is in the autonomous mode, one or more lights positioned on the vehicle to a first state; and actuate, when the vehicle is in the alternate mode, the one or more lights to a second state.

Abstract: A method is provided. An unmanned aerial vehicle (UAV) can be operated in an autonomous mode, performing course corrections from sensor data using an object detection processor and a decision processor. The UAV can then enter a hover mode if an override condition is present and enter a remote-control mode once the UAV is in the hover mode. In the remote-control mode, flight control commands can be received via the cellular module so as to position the UAV in response to the flight control command.

Abstract: A golf ball kicking device adapted to be worn on the toe of a shoe comprisinga first member having a concavity including a flexible surface adapted to be positioned against a toe of a shoe;a second member detachably connected to said first member and having a golf ball striking surface adapted to be mounted in front of the toe of the shoe, said striking surface having an area approximating the area of a selected golf iron and a slope approximating the slope of said selected golf iron; andan adjustable strap fastened at opposite ends thereof to the first member for maintaining said first member in a fixed and abutting relationship with said toe of said shoe.

Abstract: An educational device (10) for facilitating vocabulary development includes a display (11) for displaying reading text, a keyboard (12) and microprocessor (14). The reader selects target words or short phrases whose meaning may be unfamiliar. A context-sensitive sentence illustrating the meaning of the selected portion of the reading text and including the target word or phrase is provided and displayed for a first preselected period. The target word or phrase in the context-sensitive sentence is replaced with verification text and displayed for a second preselected period. A test function furnishes context-sensitive questions that check the reader's understanding of the correct meaning. Performance information is collected and presented upon request.

Abstract: This invention relates to substituted ethylenic imidazoles and triazoles, their enantiomorphs, acid addition salts and metal complexes as well as their methods of preparation and use as broad spectrum systemic fungicides useful in controlling phytopathogenic fungi such as barley net blotch (Helminthosporium teres), bean powdery mildew (Erysiphe polygoni), peanut cercospora (Cercospora arachidicola), and wheat stem rust (Puccinia graminis f. sp. tritici race 15B-2).

Abstract: This invention relates to 1 and 4-aralkyl-1,2,4-triazoles, their enantiomorphs, acid addition salts and metal salt complexes. This invention also relates to the method of preparation and use of these compounds. These compounds are highly active broad-spectrum systemic fungicides effective in controlling phytopathogenic fungi such as barley net blotch (Helminthosporium teres), grey mold (Botrytis cinerea), bean powdery mildew (Erysiphe polygoni), grape downy mildew (Plasmopora viticola), rice blast (Piricularia oryzae), tomato late blight (Phytophthora infestans) and wheat stem rust (Puccinia graminis f. sp. tritici race 15B-2).

Abstract: A storage rack for supporting an ensemble of implements alongside an upright support surface includes a base member and a plurality of removable supports rods. The base member has a plurality of equidistantly spaced, angled support rod bores in its front face, and each support rod has a first end portion sized for close-fitting, slideable mated engagement in each of the support rod bores. Fasteners may mount the base member to the support surface. Preferably, the support rod bores are at an acute angle to the front surface so that, when a support rod is inserted, the rod extends forwardly and upwardly to terminate in a free end. The rod and bore sizes may be selected so that the free end of each support rod is in a common plane with the top surface of the base member. Tremendous versatility in the configuration of an array of active support rods is therefore provided, and, in the alternate exemplary embodiments, storage bores and a storage groove are respectively disclosed for holding extra storage.

Abstract: Extendible and pivotable mirrors for vehicles which include in a first preferred embodiment, an extendible mirror attached to a piston mounted in a fluid-operated cylinder secured in the door or fender panel of a vehicle. In a preferred embodiment, the extendible mirror is extended outwardly of the vehicle fender or door panel by operation of the cylinder and is manually pivotally adjusted for rear-view observation by the driver. The extendible mirror may be retracted in a mirror well located in the fender or door panel when not in use. In a second preferred embodiment of the invention, a pivoting mirror is first pivoted from a mirror well to a desired position by operation of a fluid-operated cylinder and is subsequently manually adjusted to a functional location for rear viewing from inside the vehicle. As in the case of the extendible mirror, the pivotable mirror can be pivoted into a mirror well located in the fender or door panel of the vehicle when not in use.

Abstract: A method and apparatus for cleaning cotton is disclosed wherein an air stream bearing cotton is introduced into an inlet chamber having side-by-side outlet ducts covered with a screen that collects cotton yet lets trash pass therethrough. The air stream is alternately diverted from one outlet duct to the other so that while cotton is accumulating on the screen in front of one duct, it is being removed from the other. The cotton, as it is removed from the screen, falls onto an inclined shaker screen which vibrates additional dirt from the cotton before it is discharged from the apparatus.
