Patent CA-2618157-A1 (CA)
Inventor: AIELLO ROBERT A
IPC: G08C23/02
Filed: 2008-01-21
Abstract: Method and apparatus for optimizing mud pulse telemetry data rate by processing a sequence of measured pulses to minimize adverse effects of pressure pulse reflections, attenuations and distortions. A downhole telemetry unit cooperating with a sensor and disposed in a MWD or LWD logging tool generates a sequence of pulse within the mud column. The sequence is encoder to represent the response of the sensor disposed within the logging tool. The encoded pulse sequence is sensed at the surface of the earth using a pressure transducer. The output of the transducer yields an electrical signal that is typically attenuated and can contain reflections and distortions. This measured signal output is processed to minimize the effects of pulse reflections, attenuations and distortions thereby yielding a primary pulse sequence that is more representative of the response of the sensor and allowing an increase in mud pulse telemetry data rate.

Inventor: SCHNETZKA HAROLD R
IPC: F25B49/02
Filed: 2007-06-07
Abstract: A method of providing ride-through capability in a chiller/refrigeration system employs a variable speed drive with an active converter stage, a DC  link stage and an inverter stage for providing variable frequency and voltage to power at least one motor. An induction motor is coupled to the output of the inverter stage for driving a compressor in the chiller/refrigeration system. The ride-through method comprises operating the active converter to regulate the DC link voltage of the DC link stage to a predetermined voltage level until the current through the active converter equals a predetermined current limit, then transferring regulation of the DC link to the inverter upon reaching the current limit of the converter. The compressor is unloaded, and the power flow through the inverter is reversed to maintain the voltage level of the DC link stage. Pre-rotation vanes, slide valve, or check valve are used to unload the compressor.

Filed: 2007-04-13
Abstract: A method for adaptive conventional scanning in a two-way radio transceiver (300) includes initiating an unweighted scan behavior (301) from a scanning list and then determining if qualified activity is present on a scanned channel (303) for a predetermined number of scan cycles. Once qualified activity is detected, the scanned channel is then marked (307) as having high activity. The transceiver then switches (309) to a weighted scan behavior such that the marked channel will be checked at a higher periodic rate than an unmarked channel. Once qualified activity is detected on the marked channel for a predetermined number of cycles (311) the channel is unmarked (315) and the weighted nature of the scan is removed such that normal scanning activity is resumed (317). The marking process increases the overall scanning rate enhancing the overall performance of the scan for all channels.

Abstract: Metallic stents are treated with a gaseous species in a plasma state unde r conditions causing the species to polymerize and to be deposited in polyme rized form on the metallic stent surface prior to the application of a drug- polymer mixture, which is done by conventional non-plasma deposition methods . The drug-polymer mixture once applied forms a coating on the stent surface that releases the drug in a time-release manner and gradually erodes, leavi ng only the underlying plasma-deposited polymer. In certain cases, the plasm a-deposited polymer itself erodes or dissolves into the physiological medium over an extended period of time, leaving only the metallic stent. While the various polymers and drug remain on the stent, the plasma-deposited polymer enhances the adhesion of the drug-polymer anchor coating and maintains the coating intact upon exposure to the mechanical stresses encountered during s tent deployment.
