| 20120128054 | SINGLE PATH DETECTION AND EQUALIZER OPTIMIZATION - An algorithm to detect single path channel conditions and reduce the span (number of taps) of the equalizer in order to mitigate the performance degradation caused by noisy equalizer taps is disclosed. The algorithm provides two novel components comprising single path scenario detection and single path scenario processing or (equalizer shortening). A single path scenario is detected when the energy concentrated in a single channel impulse response tap divided by the total energy of the taps exceeds a predetermined threshold. When a single path scenario is detected, only the equalizer taps within a variable window around the equalizer tap having concentrated energy are used to filter the received signal. | 05-24-2012 |

| 20090014293 | PROCESSED BOLT END USEFUL IN A TURN SIGNAL SWITCH ASSEMBLY - A turn signal switch assembly is constructed having a switch stalk and junction box rotatably coupled using a shoulder bolt. The shoulder bolt has a shoulder area useful for allowing the switch stalk to rotate freely relative to the junction box. The threaded end of the shoulder bolt is turned and tightened into at least one corresponding threaded aperture in the junction box, thereby mechanically coupling the switch stalk to the junction box. The threaded end of the shoulder bolt also extends past a surface of the junction box so that the threaded end is exposed. The threaded end is mechanically transformed by an orbital riveting device so as to act as a positive locking feature. The shoulder bolt thereafter secures the switch stalk to the junction box using the mechanical advantages of a threaded connection in combination with the positive locking feature of a riveted connection. | 01-15-2009 |

| 20100056133 | Data Compaction Techniques - Many areas of technology need highly accurate data compression to provide small, multifunctional devices. For example, in the area of communication governed by the IEEE 802.11 standards, a wireless device could significantly improve its performance by using its calibration data. Moreover, because of the increased mobility of users, a wireless device should be able to operate in different regulatory domains. This flexibility requires access to significant amounts of data regarding such regulatory domains. Advantageously, piecewise linear abstraction and/or mapping can be used to significantly reduce the amount of stored data while ensuring accuracy in reproducing the total data at a later point in time. | 03-04-2010 |
| 20120002704 | Measuring Received Signal Strength on Neighboring Frequencies of a Channel with Interference in a Wireless Device - System and method for operating a wireless narrowband receiver. A signal may be received on a channel of the wireless narrowband receiver. At least a portion of the signal may be received from a first wireless narrowband transmitter. The wireless narrowband receiver may implement an adaptive frequency hopping algorithm. It may be determined if interference is present on the channel and one or more errors are detected in receiving the signal. In response to determining that interference is present on the channel and one or more errors are detected in receiving the signal, received signal strength of one or more neighboring frequencies of the channel may be measured, and the resulting measurements may be stored in a memory. The measurements may be used to determine interference sources interference on the channel. | 01-05-2012 |

| 20080233602 | Detecting and profiling molecular complexes - Methods are provided for detecting the formation of complexes of molecules, especially proteins, in a sample, such as a cell or tissue lysate. In one aspect, a cleaving probe specific for a first protein in a complex and one or more binding compounds specific for one or more second proteins in a complex are provided. Upon binding, the cleaving probe is induced to generate an active species, such as singlet oxygen, that cleaves molecular tags attached to the binding compounds only in the local region of the cleaving probe. The released molecular tags are separated from the assay mixture and from one another to provide a readout that is related to the number and types of proteins present in the complex. | 09-25-2008 |
| 20090111127 | Surface Receptor Complexes as Biomarkers - The invention is directed to a new class of biomarker in patient samples comprising dimers of cell surface membrane receptors. In one aspect, the invention includes a method of determining the status of a disease or healthful condition by correlating such condition to amounts of one or more dimers of cell surface membrane receptors measured directly in a patient sample, in particular a fixed tissue sample. In another aspect, the invention includes a method of determining a status of a cancer in a specimen from an individual by correlating measurements of amounts of one or more dimers of cell surface membrane receptors in cells of the specimen to such status, including presence or absence of a pre-cancerous state, presence or absence of a cancerous state, prognosis of a cancer, or responsiveness to treatment. Preferably, methods of the invention are implemented by using sets of binding compounds having releasable molecular tags that are specific for multiple components of one or more types of receptor dimers. After binding, molecular tags are released and separated from the assay mixture for analysis. | 04-30-2009 |
| 20090155818 | Measuring Receptor Homodimerization - The invention provides methods and kits for detecting and/or measuring receptor homodimers on a cell surface membrane. In one aspect, the methods employ pairs of probes comprising binding compounds and a cleaving probe, such that at least one binding compound binds specifically to the same epitope of a membrane-bound analyte as the cleaving probe. The binding compound includes one or more molecular tags attached through a cleavable linkage, and the cleaving probe includes a cleavage-inducing moiety that can cleave the linkage when within a defined proximity thereto. Binding of the two probes to a homodimer of a cell surface molecules results in release of molecular tags from the binding compounds, providing a measure of formation of the homodimeric complex. | 06-18-2009 |
