Abstract: A method for manufacturing surgical blades (2402) from either a crystalline or poly-crystalline material, preferably in the form of a wafer (202), is disclosed. The method includes preparing the crystalline or poly-crystalline wafers by mounting them and machining trenches into the wafers. The methods for machining the trenches, which form the bevel blade surfaces, include a diamond blade saw (502, 504, 506, 508), laser system (900), ultrasonic machine (100), and a hot forge press (1052, 1054). The wafers are placed in an etchant solution (1402) which isotropically etches the wafers in a uniform manner, such that layers of crystalline or poly-crystalline material are removed uniformly, producing single or double bevel blades (20A-G). Nearly any angle can be machined into the wafer which remains after etching. The resulting radii of the blade edges is 5-500 nm, this is equivalent to a diamond edged blade manufactured at a fraction of the cost.

Title: Method and application for open hole gravel packing
Inventor: HILL LEO E JR
IPC: E21B43/04
Filed: 2003-03-20
Granted: 2009-12-01
Abstract: The apparatus includes a gravel pack assembly comprising a gravel pack body and a crossover tool (50). The gravel pack body comprises a pressure set packer (22) , one or more production screens (16) and a plurality of axial position indexing lugs. The crossover tool comprises auxiliary flow chambers, packer by-pass channels (82, 84), a crossover tool check valve (90, 92)and an axial position indexing collet (140). The gravel pack body and crossovertool (50) are assembled coaxially as a cooperative unit by a threaded joint (55) and the unit is threadably attached to the bottom end of a tool string for selective placement within the wellbore. Set of the packer secures the gravel pack body to the well casing and seals the casing annulus around the gravel pack assembly. A positive fluid pressure is maintained on the wellbore wall in the production zone throughout the gravel packing procedure and in particular, during the packer seal test interval when fluid pressure that is egual to or greater than the normal hydrostatic pressure is maintained on the production zone wall under the gravel pack body packer while greater test pressure above the hydrostatic is imposed in the wellbore annulus above the packer.

Abstract: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.

Abstract: A method and system for identifying schemas of web databases is provided. A schema matching system generates a mapping between an interface schema and a result schema of a web database, which is used to represent the underlying database schema. The schema matching system also generates a mapping of the interface attributes and the result attributes of the web database to global attributes of a global schema whose semantics are known. Using these mappings, a search engine service can formulate queries using the global attributes, map those queries to the corresponding interface attributes, submit the query, and retrieve the values from the result attributes that correspond to the desired global attributes.

Title: Bitless bridle with crossover reinstrap stabilizer
Inventor: BROOKS ZOE C
IPC: B68B1/04
Filed: 2005-09-29
Granted: 2007-08-14
Abstract: A bitless bridle with crossover reinstrap stabilizer in English and Western style for riding, driving and training horses and like animals that achieves improved turning and slowing/stopping by threading reinstraps through a crossover reinstrap stabilizer under the horse's jaw, lining the inside of the noseband with rubber gripping or similar textured material, and improved arrangement of component straps. In both styles, a single crownpiece strap over the poll attaches on each side of the face to reinstraps that pass across the animal's cheek, through a crossover rein strap stabilizer under its jaw, then through rings attached to a noseband, and finally to reins. Pulling on a single rein places pressure on the reinstrap on the cheek of the opposite side of the animal's head, causing it to turn in the direction pulled. Pulling on a both reins places pressure on the noseband and the poll, causing the animal to slow or stop.
