| 20100332502 | METHOD AND SYSTEM FOR SEARCHING NUMERICAL TERMS - A method and system for searching numerical terms are provided. The method includes processing a numerical term to a stem, the stem being in the form of a number, and a distance measurement of the numerical term to the stem, wherein a numerical term is a string of characters identified as a number by a numeric parser, and indexing the numerical term in a search index by the stem for search retrieval. The method includes receiving a query and processing the query to divide it into terms, including a numerical term. The numerical terms of the query are also processed to a stem and a distance measurement and document results are retrieved for the stem from an index. | 12-30-2010 |

| 20120076188 | Close-loop power transmission calibration - A close-loop power calibration algorithm is performed on a wireless communication device to correct power amplifier pre-distortion or PADR correction curves. In addition to peak to average power ratio or PAPR detection techniques, an algorithm or process is implemented that uses a transmitted reference packet, such as an orthogonal frequency domain multiplexing (OFDM) packet. The reference packet is used to learn the linear response of a detector that measures output of the power amplifier. The transmitted packet can include a linear response. The included linear response can determined by subtracting a normal packet from the reference packet. | 03-29-2012 |
| 20120076237 | Close-loop power amplifier pre-distortion correction - Attenuation is provided at the output of a power amplifier that provides transmitted signals or packets. The attenuation particularly provides separation of linear and non linear behavior of the signals. A reference packet is transmitted during attenuation. A normal packet is delivered without attenuation. Feedback from the reference packet can be extracted using the normal packet to calculate a loop-back response that is extracted and sent to a power amplifier pre-distortion correction algorithm. | 03-29-2012 |
| 20120077450 | Power calibration under voltage standing wave ratio change by frequency sweep - A power calibration algorithm is performed on a wireless communication device, where power measurements are taken across frequency sweep at the output of the device and at a power amplifier of the device, to accurately track voltage standing wave ratio impedance and errors associated with VSWR impedance. The measurements are performed as part of production of the wireless communication device and during online operation of the wireless communication device. During online operation the measurements are made by a detector at the power amplifier over the various frequencies of the frequency sweep. | 03-29-2012 |

| 20100024034 | DETECTING MACHINES COMPROMISED WITH MALWARE - A computer system can be configured to identify when it has been infected with or otherwise compromised by malware, such as viruses, worms, etc. In one implementation, a computer system receives and installs one or more decoy contacts in a contact store and further installs one or more malware reporting modules that effectively filter outgoing messages. For example, a malware reporting module can redirect messages with a decoy contact address to an alternate inbox associated with the decoy contact. The same malware reporting module, or another module in the system, can also generate one or more reports indicating the presence of malware, either due to detection of the decoy contact address, or due to identifying messages in the decoy contact inbox. The host computer system that sent the message to the decoy contact can then be flagged as infected with malware. | 01-28-2010 |

| 20090210439 | METHOD FOR EFFICIENT DATA TRANSFORMATION - A digraph including a plurality of ordinary nodes, at least one of a composition node and a decomposition node, and a plurality of arcs interconnecting any of said nodes. | 08-20-2009 |
| 20100094907 | Preservation Aware Fixity in Digital Preservation - A computer based method for the preservation of a digital information in a data set includes receiving a data set to be preserved, the data set including a plurality of preservation objects; creating a fixity table, the fixity table including one or more data types corresponding to preservation data types contained in the preservation objects, each data type being assigned an importance rank and one or more fixity function; for each preservation object, creating a Merkle tree corresponding to the preservation object and based on the fixity table. | 04-15-2010 |
| 20100318547 | PRESERVATION OF DIGITAL CONTENT - Methods for generating a characterizing summary and generating a collection of relevant preservation objects in a preservation system are provided. A characterizing summary is generated by collecting first information about a preservation object; collecting second information about other preservation objects or other metadata; generating a characterizing summary according to the first information and the second information; and adding the characterizing summary to the preservation object. A collection of relevant preservation objects is generated by accessing one or more preservation objects by way of one or more metadata included in a target preservation object constructed for content data; determining whether each of the accessed preservation objects is relevant to the target preservation object; adding each relevant preservation object to a list of relevant preservation objects; and generating the collection of relevant preservation objects according to the list of relevant preservation objects. | 12-16-2010 |
