| 20110282932 | ASYMMETRIC END HOST REDUNDANCY ELIMINATION FOR NETWORKS - An end host redundancy elimination system and method to provide redundancy elimination as an end system service. Embodiments of the system and method use optimization techniques that reduce server central processing unit (CPU) load and memory footprint as compared to existing approaches. For server storage, embodiments of the system and method use a suite of highly-optimized data structures for managing metadata and cached payloads. An optimized asymmetric max-match technique exploits the inherent structure in data maintained at the server and client and ensures that client processing load is negligible. A load-adaptive fingerprinting technique is used that is much faster than current fingerprinting techniques while still delivering similar compression. Load-adaptive means that embodiments of the fingerprinting technique can adapt CPU usage depending on server load. Embodiments of the system and method operate above the transmission control protocol (TCP) layer, thereby reducing the number of roundtrips needed for data transfer. | 11-17-2011 |

| 20090064771 | METHOD OF OPERATING AN ATOMIC FORCE MICROSCOPE IN TAPPING MODE WITH A REDUCED IMPACT FORCE - In a tapping mode Atomic Force Microscope (AFM) system, a probe is excited at an excitation frequency other than the probe's first natural frequency to produce a response signal manifesting a grazing bifurcation between “non-collision” and “collision” states of the AFM system, so that an additional characteristic frequency component is generated in the “collision” state. The magnitude of the additional characteristic frequency component is monitored in real time, and the probe-sample separation is adjusted to maintain the monitored magnitude at an optimal value to operate the AFM system at near-grazing conditions. | 03-12-2009 |

| 20090119300 | TECHNIQUE FOR EDITING CENTRALIZED DIGITALLY ENCODED INFORMATION - A technique is disclosed herein for editing centralized digitally encoded content using a stateless client on a client machine. A repository on a central server is accessed by a user. The repository has a plurality of compilation units stored therein. One or more compilation units selected by the user are provided to the user via a stateless client on a client machine. The client is in communication with the repository over a network. Information associated with the one or more selected compilation units is programmatically sent to the repository at spaced time intervals. | 05-07-2009 |

| 20110051640 | SYSTEM AND METHODS FOR REDUCING POWER CONSUMED BY A BASE STATION - The present invention provides systems and methods that enable a base station to consume less power. According to an embodiment of the invention, the base station reduces its power consumption by not continuously broadcasting control information. In such an embodiment, a mobile station that seeks access to a network to which the base station provides access does not search for broadcast control information prior to transmitting an access message to the base station, but rather simply transmits on a predetermined access channel an access request message. A base station that receives the access request message may unicast control information to the mobile station. | 03-03-2011 |
| 20110064043 | SYSTEM, METHOD, AND APPARATUS FOR IMPROVED SPACE-TIME CODING AND DYNAMIC SWITCHING WITH ADVANCED RECEIVERS - Methods and apparatus for allocating time-frequency resources to mobile terminals in a wireless communications system in which time-frequency resources may be selectively used according to a first multiple-input multiple-output (MIMO) transmission scheme or a second MIMO transmission scheme that differs from the first MIMO transmission scheme. An exemplary method comprises, for at least a first scheduling instance, identifying a first group of mobile terminals corresponding to the first MIMO transmission scheme and a second group of mobile terminals corresponding to the second MIMO transmission scheme, allocating time-frequency resources in a first pre-determined time-frequency zone exclusively to mobile terminals belonging to the first group, and allocating time-frequency resources in one or more additional pre-determined time-frequency zones to one or more mobile terminals belonging to the second group. This method may be implemented in a base station of a WiMAX system, for example. | 03-17-2011 |

| 20110222696 | CONFIGURABLE ELECTRONIC DEVICE REPROGRAMMABLE TO MODIFY THE DEVICE FREQUENCY RESPONSE - A test signal generator provides a test signal to an acoustic device under test and a data acquisition device acquires data from the acoustic device. The initial frequency response of the signal path through the acoustic device is determined based on the test signal and the acquired data. A target frequency response is selected. A desired configuration of a configurable circuit in the signal path is determined modifying the signal path such that the frequency response of the signal path is substantially similar to the target frequency response. At least one parameter for at least one programmable component of the configurable circuit is determined and programmed into the programmable component. | 09-15-2011 |

| 20100302706 | METHOD FOR FABRICATION OF CERAMIC DIELECTRIC FILMS ON COPPER FOILS - The present invention provides a method for fabricating a ceramic film on a copper foil. The method comprises applying a layer of a sol-gel composition onto a copper foil. The sol-gel composition comprises a precursor of a ceramic material suspended in 2-methoxyethanol. The layer of sol-gel is then dried at a temperature up to about 250° C. The dried layer is then pyrolyzed at a temperature in the range of about 300 to about 450° C. to form a ceramic film from the ceramic precursor. The ceramic film is then crystallized at a temperature in the range of about 600 to about 750° C. The drying, pyrolyzing and crystallizing are performed under a flowing stream of an inert gas. In some embodiments an additional layer of the sol-gel composition is applied onto the ceramic film and the drying, pyrolyzing and crystallizing steps are repeated for the additional layer to build up a thicker ceramic layer on the copper foil. The process can be repeated one or more times if desired. | 12-02-2010 |
