Abstract: A lift bail assembly includes a lift bail frame, two distal lift clamps, two or more proximal lift clamps, and two stops. The lift bail frame includes an attachment cutout to attach the lift bail frame to a lifting device. The lift bail frame extends at least half of a body length of the unmanned underwater vehicle (UUV) where at least ? of a weight of the UUV is directly supported by the lift bail. The two distal lift clamps are positioned opposite each other at each end of the lift bail frame. The two or more proximal lift clamps are positioned anywhere on the lift bail frame between the two distal lift clamps. The two stops fit into two stop cutouts on the UUV and are centered on the lift bail frame. All lift clamps that encompass the UUV are rigidly fixed to the lift bail frame.

Abstract: A system for autonomously determining optimal paths without collision through a travel volume for a swarm of vehicles is disclosed. The system determines a travel path for the swarm leader vehicle using a minimal cost path derived from various measures of environmental cost for avoiding objects in traveling from leader location to target location. The system also determines, for each empty neighbor location of each follower vehicle, relational costs for follower vehicle travel relative to leader vehicle travel. The various measures of relational cost seek to maintain a prescribed positional relationship between each follower vehicle and the leader vehicle given the leader vehicle travel path. Based on various measures of environmental and relational cost, the system determines the best travel path for the each follower vehicle relative to the leader vehicle.

Abstract: Devices, methods and techniques related to image rendering for ground-penetrating radar (GPR) systems are disclosed. In one example aspect, a method for producing one or more images associated with a GPR includes receiving information representative of signals received by the GPR, determining at least three frequency bands associated with the received information, assigning color values to the received information corresponding to the at least three frequency bands, and generating a color image for the one or more objects by combining the received information in all of the at least three frequency bands together such that the color values in the color image indicate a size of the one or more objects, a depth at which the one or more objects is buried underground, or an electrical permittivity of the one or more objects.

Abstract: A lawn raking assembly for mounting a rake to a lawn tractor includes a rake mount that has a pair of pivot points which each pivotally engages a front end of a lawn tractor having the rake mount extending forwardly from the front end of the lawn tractor. A rake is removably attached to the rake mount for raking the lawn in front of the lawn tractor when the lawn tractor is driven. The rake has a pair of raking elements that each extends outwardly beyond a full transverse width of the lawn tractor. A linkage is coupled to the rake mount and a handle is pivotally coupled to the lawn tractor. The handle pivotally engages the linkage for urging the rake between a lifted position and a lowered position.

Abstract: A method of coregistering images is disclosed. Two dimensional images are first preprocessed, including clipping values in each image to a specified standard value range, and then applying a local equalization technique to the clipped images. Feature extraction is then performed to identify one or more features in the images. One or more of the extracted features are then matched between images to determine a degree of overlap between the images and a relationship between image coordinates of the images. The images are then transformed to a common coordinate system based on the degree of overlap and the relationship between their image coordinates. The images are then combined to form a single image.

Abstract: A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow pole section modules, each module having an elongated structure with a base end and an opposed tip end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the tip end of a base module with the base end of an additional module. One or more than one of the modules forming the elongated modular pole structure comprise a composite material having fire resistant properties.

Abstract: An improved graphical user interface (GUI) for use with a computing device that arranges information/icons in a circular or loop-like fashion. The GUI includes a plurality of nodes arranged on a circular element. The GUI may display only a portion of the circular element and associated nodes and may permit the user to rotate the circular element to rotate the circular element to bring the nodes into the displayed area. The user may select a node to access the selected node and bring a new sub-circle associated with that node into view (in a sub-circle embedded within a circle arrangement).
