20140376330 | WIDE AZIMUTH SEISMIC DATA ACQUISITION METHOD AND SYSTEM WITH AT LEAST THREE STREAMER SETS - Wide azimuth data acquisition systems using at least three streamer sets achieve shorter survey time and enhanced angular coverage relative to conventional systems using two streamer sets. Various techniques such as high-density seismic source activation and alternating surveyed bands with skipped bands lead to data quality similar to the conventional system, while maintaining the increased productivity advantage. | 12-25-2014 |

20090102487 | Method for Validating Printed Circuit Board Materials for High Speed Applications - A method for testing a printed circuit board to determining the dielectric loss associated with the circuit board material relative to a standard. Dielectric losses in the material generate heat when a high frequency electronic signal, such as a microwave frequency signal, is communicated through a microstrip that is embedded within the printed circuit board. The temperature or spectrum at the surface of printed circuit board is measured and compared against the temperature or spectrum of the standard to determine whether the material under test is acceptable. While various temperature measurement devices may be used, the temperature is preferably measured without contacting the surface, such as using an infrared radiation probe. | 04-23-2009 |

20100331818 | NEEDLE FOR OPHTHALMIC PROCEDURES - The present invention provides a needle suitable for performing ophthalmic surgical procedures. The needle includes a flexible curved tube and an adapter which can attach the needle to a syringe for delivering anesthetic. The flexible curved tube may be of plastic, particularly PTFE, and is typically attached to the adapter by a connector. Employing a needle with a flexible curved tube significantly reduces the risk of trauma of a patient s eye during an ophthalmic surgical procedure such as a sub-Tenon s block procedure. | 12-30-2010 |
