摘要:
An arrow nock and release system for holding and then releasing an arrow from a bow wherein a ball nock is positioned on an end of an arrow shaft, the ball nock having an at least partially spherical outer surface divided with a string groove. An arrow release is engageable with the ball nock and includes a jaw with an engagement surface corresponding with the outer surface of the ball nock, the jaw releaseably engageable with the ball nock.

A method and a system for adaptive image enhancement are provided for measuring the image quality of a pixel region in a frame, performing an image classification based on the image quality measurement, and enhancing image quality by applying operations according to image classification of the region. Also provided is a method as above including the steps of dividing a frame into P pixel regions; and for each one of the pixel regions measuring the image quality; assigning an image quality class; and enhancing the image. Also provided is a system for adaptive image enhancement including a circuit to measure the image quality of a pixel region in a frame in a source video image; a circuit to perform an image classification of the region based on the image quality measurement; and a circuit to enhance the image quality of the region in the source video image a by applying operations based on the image classification of the frame.
摘要:
A system and method for managing software application windows in a graphical user interface having a desktop and taskbar display area are provided. Each instantiated program is represented as one or more graphical windows in the desktop and as a control tile in the taskbar. Control tiles are grouped into control tile groups that facilitate organization and single access control. Project control tile groups allow the grouping of multiple software applications. Additionally, minimized control tile group layout and state may be preserved and previewed prior to being restored.

A helical turbine configured to rotate transversely within a cylindrical pipe under the power of fluid flowing either direction therethrough is operatively coupled with a rotating machine or generator to produce work or electricity. The twisted blades of the turbine define a right circular cylinder when the shaft mounting them rotates under the influence of fluid flow through the pipe. In one embodiment, baffles are provided at least upstream of the cylindrical turbine and within the cylindrical pipe to control flow through the cylindrical turbine. The twisted blades of the helical turbine are airfoil in cross section, as are the radial struts or spokes that mount the twisted blades to the rotatable shaft, thereby to optimize hydrodynamic flow, to minimize cavitation, and to maximize conversion from axial to rotating energy.
摘要:
An apparatus and method for attaching a vane with respect to a shaft of an arrow or a crossbow bolt. The vane is attached to a sleeve that is positionable over an outer surface of the shaft. The sleeve has an inner surface and the shaft has an outer surface. In an attached position of the vane with respect to the shaft, an adhesive, such as a phase change adhesive, is positioned between and contacts at least a portion of the inner surface of the sleeve and at least a portion of the outer surface of the shaft.

Various technologies and techniques are disclosed that improve data searching on mobile devices. A facet-based search application is provided that has a filter region, a results region, a facet navigation region, and a menu region. A user applies a facet-based filter to a set of data by selecting a number on a keypad or other area that correlates spatially to a filter option in the facet navigation region. A set of data in the results region is updated based on the applied facet-based filter. The user can also apply a freeform text filter to the data by selecting one or more characters for which to search. The data displayed in the results region is updated based on the applied freeform text filter. When input is received from the user to save the applied filter, an attribute label is displayed as a query term in the filter region.
