摘要:
Tools, devices, apparatus, systems and methods to enhance ball handling skills and reduce and eliminate fumbling of balls, from football players, basketball players and the like. The training tool can be used to improve ball security for football players of every level to reduce or even eliminate fumbling. The tool can simulate the forces imparted on a football that can cause a fumble during the game. Used during various drills in practice, the invention will improve the player's ability to maintain possession of the football during actual game play. The invention assembly can include a ball (such as a football, basketball or rugby ball), a rope, and a reciprocating handle weight subassembly. The tools can use a slightly vertical handheld sliding reciprocating weight with or without a spring(s), or motor, in order to cause shockwaves that pass to a player carrying a ball to simulate a fumbling condition during a game, where other players are trying to slap or grab or push or jar loose a ball from the grasp of the ball carrier. The reciprocating weight can be quickly pumped and/or jerked by the trainer/coach during drills to surprise and replicate a fumbling condition.

A sensor to detect particulate matter. The sensor includes a first rigid tube, a second rigid tube, a detection surface electrode, and a bias surface electrode. The second rigid tube is mounted substantially parallel to the first rigid tube. The detection surface electrode is disposed on an outer surface of the first rigid tube. The detection surface electrode is disposed to face the second rigid tube. The bias surface electrode is disposed on an outer surface of the second rigid tube. The bias surface electrode is disposed to face the detection surface electrode on the first rigid tube. An air gap exists between the detection surface electrode and the bias surface electrode to allow particulate matter within an exhaust stream to flow between the detection and bias surface electrodes.

The present invention relates to a latch for securing together a panel to a keeper thus permitting opening and closing of a portion of the panel while allowing the remaining portion of the panel to remain closed. When the latch is unlatched from a keeper, a user can refasten the panel by lowering the panel until the main pawl and the keeper are fastened together by the action of the keeper on the pawl of the latch. The latch also provides for the opening and closing of a portion of one of the panels while allowing the remaining portion of that panel to remain closed.

Disclosed are filled and plasticized blends of (a) from about 10 to about 79% by weight of at least one copolymer derived from copolymerization of ethylene and at least one additional copolymer selected from the group consisting of vinyl esters of saturated carboxylic acids wherein the acid moiety has up to 4 carbon atoms, unsaturated mono- or dicarboxylic acids of from 3 to 5 carbon atoms, salts of said unsaturated acids and esters of said unsaturated mono- or dicarboxylic acids wherein the alcohol moieties forming said esters have from 1 to 6 carbon atoms; (b) from about 1 to 20 percent by weight of at least one plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers, and polyether esters; (c) from about 20 to about 60% by weight of hollow filler; (d) from about 0.05 to about 5% by weight of at least one organic acid or acid derivative selected from the group consisting of dimer and trimer acids having from 36 to 60 carbon atoms, and mixtures thereof; and optionally (e) from 0 to about 5% by weight of tackifier. Also disclosed are sound management sheets that comprise these compositions. Also disclosed are carpets, especially automotive carpets, having backside coatings comprising these compositions; and construction panels comprising these compositions.

The pad assembly is made up of three pads of resilient foam material assembled one on top of the other, the center pad having a greater density than the outer pads. The center pad has three cut-out openings at locations corresponding to the maximum pressure points exerted by a person sitting on the pads, these openings including a filler foam of density less than that of the outer pads, the overall assembly distributing pressure against a person seated thereon.

Disclosed is an anchor for rock or similar material, and methods therefor. The anchor has a hinged base, which base consists of at least a pair of pivotally connected wings, the wings able to pivot about at least one longitudinal axis between, a first position in a closed state and a second position in an open state, the open state having a dimension between opposing parts of each wing that is greater than when in the closed state. A locking mechanism locks the wings in either the first position, or the second position. A connecting portion adapted to enable a load to be connected to the anchor connects to the hinged base, the connecting portion having a loading axis which is substantially parallel to the longitudinal axis. The anchor can be set between either the first position, or the second position, and then anchored to enable a load to be connected thereto.
摘要:
A method includes parsing a text source document to construct a document node tree such that the document node tree includes text offsets indicating the location of the text within the text source document corresponding to each node of the document node tree. The method includes constructing, from the document node tree, a Document Object Model (DOM) and a view node tree that represents the DOM. The constructing of the view node tree includes mapping the view node tree to the document node tree. The method includes providing a running representation of the DOM such that DOM elements of the DOM are linked to the text within the text source document corresponding to the DOM elements via the view node tree and the document node tree.

A method and system for constructing and delivering sponsored search contracts is provided. In one implementation, the method may include generating a financial instrument with terms, such as a contract, for selling click-throughs. The terms may include a volume of click-throughs, a price, and a core market. The price of the contract may be related to an expected quality of the advertisement. The core market may be described in terms of key words. The contract terms may be communicated to an advertiser. The advertiser may then bind an advertisement to the contract or sell the contract to another advertiser. The contract performance may be tracked and communicated.
