| 20080234491 | PROCESS FOR PREPARATION OF CELECOXIB - There is provided a process for preparation of celecoxib by reacting 4,4,4-trifluoro-1-[4-(methyl)phenyl]butane-1,3-dione with 4-sulphonamidophenylhydrazine or its salt in a solvent medium that contains an alkyl ester. There is also provided a process for the purification of celecoxib using aromatic hydrocarbon solvents. | 09-25-2008 |
| 20090118514 | PROCESSES FOR PREPARING PIOGLITAZONE AND ITS PHARMACEUTICALLY ACCEPTABLE SALTS - An improved process for the preparation of pioglitazone and its pharmaceutically acceptable salts by reducing 5-[4-[2-(5-ethyl-2-pyridyl)ethoxy]benzilidene]-2,4-thiazolidinedione with sodium borohydride in presence of a cobalt ion and dimethyl glyoxime. More particularly the cobalt ion used is cobalt chloride hexahydrate, or, cobalt (II) nitrate hexahydrate in presence of mixture of DMF and water as solvents. | 05-07-2009 |
| 20090149662 | PROCESSES FOR PREPARING ZAFIRLUKAST - An improved process for the preparation of substantially pure zafirlukast and pharmaceutical compositions thereof. | 06-11-2009 |
| 20110151258 | PREPARATION OF RANOLAZINE - Preparation of ranolazine and intermediates thereof, for use in pharmaceutical compositions comprising ranolazine. | 06-23-2011 |

| 20090033422 | Multi-level slew and swing control buffer - A buffer amplifier and an associated method have been provided for slew rate and swing level control in the buffering of a signal. The method accepts an input signal having a voltage swing, a swing control signal, and a slew rate control signal. The voltage swing for each output in a set of serially-connected buffer stages is selected in response to the swing control signal. The selected voltage swing for a subset of buffer stages is modified in response to the slew rate control signal. Selecting the voltage swing for each output entails selecting a source current for each buffer stage. A bias current is generated and mirrored through a current source connected to each buffer stage. Modifying the selected voltage swing for each of the subset of buffer stages includes modifying the bias current to the subset of buffer stages. | 02-05-2009 |

| 20120062500 | ADAPTIVE HIGH DYNAMIC RANGE SURFACE CAPACITIVE TOUCHSCREEN CONTROLLER - A system for controlling a touch screen. A touch screen element having a plurality of contacts, such as one contact electrode at each of four corners. A multiplexer coupled to the touch screen element for forming a plurality of connections, such as various combinations of the contact electrodes to allow measurements to be made of the impedance of the touch screen element from the left side to the right side, from the top to the bottom, and do forth. A touch screen processor coupled to the touch screen element for determining an oscillation frequency of the touch screen element as a function of the electrode connections. | 03-15-2012 |

| 20110161344 | ENHANCING SOFT FILE SYSTEM LINKS - A method for determining whether a soft link of a target file is pointing to a correct file system is provided. A unique identification number for a mounted file system is retrieved from a storage device in response to receiving a request to access a target file in the mounted file system. In addition, an identification number is retrieved from a soft link of the target file in response to accessing the soft link of the target file in the storage device. Then, it is determined whether a match exists between the unique identification number for the mounted file system and the identification number from the soft link of the target file. In response to determining that a match does exist between the unique identification number for the mounted file system and the identification number from the soft link of the target file, access to the target file is allowed. | 06-30-2011 |
