| 20100274330 | DEVICE FOR TREATMENT OF BLOOD VESSELS USING LIGHT - Light generating devices for illuminating portions of vascular tissue to administer photodynamic therapy, and usable with, or including a distal protection device. A first device includes a hollow tip, a flushing lumen, a guidewire lumen, and at least one of a light source, and a hollow light transmissive shaft that is adapted to accommodate a light source. If desired, the device can include a balloon, so that a portion of a body lumen between the balloon and the distal protection device is isolated when the balloon is inflated. A second device includes inner and outer catheters, the outer catheter including a balloon, and the inner catheter including a light source encompassed by another balloon. Yet another device is a catheter having two balloons and a sleeve extending there between. Within the sleeve, the catheter includes a light source and an expanding member. | 10-28-2010 |
| 20100284012 | Portable and Cartridge-Based Surface Plasmon Resonance Sensing Systems - This specification discloses various improvements in the field of SPR sensing systems. One improvement relates to a portable SPR sensing system, e.g., a system contained within a suitcase that can be hand-carried to a monitoring site. Another improvement relates to a portable, cartridge-based SPR sensing system. In this system, selected portions of the system's electrical and fluidics systems are allocated between a base unit and a removable/disposable cartridge. Other improvements relate to methods or protocols for operating an SPR sensing system. Such methods provide for the elimination of false positives and increased sensitivity, e.g., by using secondary antibodies with specificity for different target epitopes and by sensor element redundancy. In addition, protocols are provided for the detection of small molecules. Such protocols may employ a competition type assay where the presence of the analyte inhibits the binding of antibodies to surface immobilized analyte, or a displacement assay, where antibodies bound to the analyte on the sensor surface are displaced by free analyte. | 11-11-2010 |

| 20090269081 | Soft Decision Threshold Control in a Signal Receiver Using Soft Decision Error Correction - A soft decision threshold control system and method may be used with a forward error correction (FEC) scheme to adjust or tune one or more soft decision thresholds in response to one or more bit value averages for the threshold(s) and in response to a bit error rate (BER). The bit value average for a soft decision threshold generally refers to an average number of binary values (e.g., logic ones and/or zeros) occurring in a bit stream detected using the soft decision threshold. For different BER levels in a particular system, for example, one or more of the soft decision thresholds may have a predetermined bit value average, which has been determined to provide a certain level of performance (e.g., an optimum performance). Thus, one or more of the soft decision thresholds may be adjusted such that the bit value averages for the soft decision thresholds are adjusted as a function of the BER. The settings of the soft decision thresholds may also be adjusted in response to changes in a signal amplitude of the input signal being detected. | 10-29-2009 |
| 20100232797 | Detection of Data in Signals with Data Pattern Dependent Signal Distortion - A detection system and method may be used to detect data transmitted in a signal with data pattern dependent signal distortion such as intersymbol interference. In general, a detection system and method compares samples of a received signal with stored samples of distorted signals associated with known data patterns and selects the known data patterns that correspond most closely with the samples of the received signal. The detection system and method may thus mitigate the effects of data pattern dependent signal distortion. | 09-16-2010 |
