Abstract: A hydrate of an acid addition bis-salt of an anthranilic acid derivative is produced by a process which comprises: (a) combining, in any order, the anthranalic acid derivative, a pharmaceutically acceptable organic solvent, an excess of water and a pharmaceutically acceptable strong acid to form a mixture; (b) warming the mixture until a clear solution forms; (c) filtering the solution while it is warm, to yield a filtrate; and (d) recovering the hydrate as defined above from the filtrate. The hydrate has a defined number of moles of water of crystallisation and possesses better storage stability and dissolution characteristics than conventionally produced hydrates of such acid addition his-salts.

Abstract: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.

Abstract: A processor complex architecture facilitates accurate passing of transient data among processor complex stages of a pipelined processing engine. The processor complex comprises a central processing unit (CPU) coupled to an instruction memory and a pair of context data memory structures via a memory manager circuit. The context memories store transient “context” data for processing by the CPU in accordance with instructions stored in the instruction memory. The architecture further comprises data mover circuitry that cooperates with the context memories and memory manager to provide a technique for efficiently passing data among the stages in a manner that maintains data coherency in the processing engine. An aspect of the architecture is the ability of the CPU to operate on the transient data substantially simultaneously with the passing of that data by the data mover.

Abstract: An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the chamber (54). A main filter element (K) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media.

Abstract: A configurable adaptive variable length data packet transmission output scheduler for enabling substantially simultaneous transmission on a common transmission link, as of fiber optics, of differentiated services for various different traffic types, executing different QOS algorithms while co-existing in a converged network environment, with simultaneous preserving of the different service characteristics for real-time or high-priority traffic and providing differentiated bandwidth allocation while achieving maximal link utilization—all through a fine and balanced control as to which type of traffic is transmitted on the link for a given duration, and how much of that traffic is transmitted on the link.

Abstract: A device to implant impurities into a semiconductor wafer had a beam gun to shoot ions at a semiconductor wafer, a pair of ion gauges, and ion gauge controller to supply power to, and obtain information corresponding to a number of ions from, one of the ion gauges. The gauge controller has a parameter output, a control output and a pair of control inputs respectively associated with the pair of ion gauges, such that when a control signal is supplied to one of the control inputs, the ion gauge controller supplies power to, and obtains information corresponding to a number of ions from, the respectively associated ion gauge. The control output produces the control signal when either of the ion gauges is activated. The parameter output selectively produces a parameter signal based on a recipe selection. A first delay circuit connects the control output to one of the control inputs, after a delay, when the parameter output is on.

Abstract: A device to implant impurities into a semiconductor wafer has a process chamber having a wall, a pressure compensation unit, a disk to support a plurality of semiconductor wafers within the process chamber. The disk has a radially extending slot arranged among the wafers. A beam gun is positioned within the process chamber to shoot an ion beam at the semiconductor wafers. A cryo pump minimizes the pressure within the process chamber. A first ion gauge is positioned between the process chamber and the cryo pump. A second ion gauge extends through the wall of the process chamber. A switching device selectively connects the first or second ion gauge to the pressure compensation unit. A faraday receives ions from the ion gun filter after the ions travel through the slot in the disk. A current meter counts the number of electrons flowing to the disk faraday to neutralize the ions.

Abstract: A process uses pressure changes and a pressure compensation factor to estimate the rate at which neutral atoms are implanted. While implanting a first wafer using a first pressure compensation factor, the rate at which ions are implanted is determined. The first wafer is moved radially with respect to an ion beam while implanting ions into the first wafer so as to achieve a uniform total dose based on the rate at which ions are implanted and the estimated rate at which neutral atoms are implanted. The pressure is determined while implanting the first wafer, determining the pressure. A second pressure compensation factor is selected, that would have achieved a uniform rate of implanted ions plus implanted neutral atoms across a surface of the first wafer. The second pressure compensation factor is different from the first pressure compensation factor. The second pressure compensation factor is used to implant a second wafer. The second wafer is tested by forming a sheet resistance contour map.

Abstract: The protection of data on a client mobile computing device by a server computer system such as within an enterprise network or on a separate mobile computing device is described. Security tools are described that provide different security policies to be enforced based on a location associated with a network environment in which a mobile device is operating. Methods for detecting the location of the mobile device are described. Additionally, the security tools may also provide for enforcing different policies based on security features. Examples of security features include the type of connection, wired or wireless, over which data is being transferred, the operation of anti-virus software, or the type of network adapter card. The different security policies provide enforcement mechanisms that may be tailored based upon the detected location and/or active security features associated with the mobile device. Examples of enforcement mechanisms are adaptive port blocking, file hiding and file encryption.
