Patent CA-2636733-A1 (CA)
Inventor: GAGNON JEFF S
IPC: A61N1/05
Filed: 2008-06-27
Abstract: Lead devices and methods for neurostimulation are described.  Some of the neurostimulation leads provided have multiple, distal region electrode contacts arranged in an array capable of providing steerable spinal cord stimulation. In one use, a collapsed introducer sheath is disposed over a dilator and advanced to a spinal cord target site through a 14-gauge needle into the epidural space. The dilator is removed and the introducer is expanded to its full width. A neurological lead according to the present invention advanced through the introducer to near the target site and the introducer removed.  The lead is wider than it is high and has a row of lower electrodes flanked by right and left side electrodes in groups of three. The lower electrodes serve as cathodes and the right and left electrodes are return anodes.

Title: System to cold compress an air stream using natural gas refrigeration
Inventor: HERRON DONN MICHAEL
IPC: F04B25/00
Filed: 2008-10-14
Abstract: An air stream is compressed in multiple stages using refrigeration derived from a refrigerant comprising natural gas for inter-stage cooling. The possibility of natural gas leaking into the air stream is reduced by use of an intermediate cooling medium ("ICM") to transfer the refrigeration from the refrigerant to the inter- stage air stream. The compressed air stream can be fed to a cryogenic air separation unit that includes an LNG-based liquefier unit from which a cold natural gas stream is withdrawn for use as said refrigerant.

Title: Molecules for the treatment of lung disease involving an autoimmune reaction to connective tissue found in the lung
Inventor: KLEMSZ MICHAEL J
IPC: G01N33/00
Filed: 2007-01-13
Abstract: Various embodiments include methods for diagnosing and treating medical conditions that involve an autoimmune response to connective tissue such as collagen found in organs such as the lung. In one method pulmonary disease and disorders such as Idiopathic Pulmonary Fibrosis (IPF) are diagnosed by analyzing fluid or tissue samples obtained from a patient for evidence of an autoimmune response to various types of collagen including, for example, Type V. One type of assay for evidence of an autoimmune response to Type V collagen comprises the steps of obtaining a fluid or tissue sample from a patient, contacting at least a portion of the sample with antigen to anti-Type V  collagen antibody and monitoring the mixture of sample and antigen for changes indicative of the presence of anti-Type V collagen in the sample. Another embodiment includes treating pulmonary diseases such as IPF by administering a therapeutically effective dose of epitopes of various collagens including Type V collagen.

Title: Simulated surround sound hearing aid fitting system
Inventor: WOODS WILLIAM S
IPC: H04R25/00
Filed: 2008-11-05
Abstract: This application relates to a system for fitting a hearing aid by testing the hearing aid patient with a three-dimensional sound field having one or more localized sound sources. In one embodiment, a signal processing system employing head-related transfer functions is used to produce audio signals that simulate a three-dimensional sound field when a sound source driven by such audio signals is coupled directly to one or both ears. By transmitting the audio signals produced by the signal processing system to the hearing aid by means of a wired or wireless connection, the hearing aid itself may be used as the sound source.

Title: Method and system for acoustic shock detection and application of said method in hearing devices
Inventor: LUO HENRY
IPC: H04R25/00
Filed: 2006-06-13
Abstract: The present invention provides a method for detecting acoustic shock in an audio input signal (s(t)), comprising the steps of monitoring the input signal (s(t) ) in the time-domain. Thereby detecting the signal floor (Sn), detecting the peak level of the input signal (L) , detecting the attack time of the input signal (tl-t0), detecting the duration of the input signal (T). Based on those detections, determining a shock contrast level (SCL) as difference between the peak level (L) and the signal floor (Sn), determining a shock index (SI) by use of a shock index normalization constant ( s ) and comparing the shock contrast level (SCL) and the shock index (SI) with respective thresholds and indicating an acoustic shock if one or both thresholds are exceeded. Thus, the present method provides a quick and reliable shock detector that operates in the time-domain. The shock detection takes place with zero time delay, or even predicts the shock before it fully goes through the signal processing.
Patent CA-2647007-A1 (CA)
Title: Rotating blade guide assembly
Inventor: JOURDAN JAMES K
IPC: B26D1/54
Filed: 2006-03-24
Abstract: A rotating blade guide assembly includes a blade guide carrier and means for rotating the carrier from a first position to a second position. The support structure for the assembly provides a means of supporting the assembly in both positions while allowing an opening for the band to be inserted without twisting in the first position. The first position would be that blade orientation when the blade is placed about a pair of band wheels. The second position would be the blade orientation when the blade is rotated 90° to a cutting position. In this way, the orientation of the blade is changed when the blade guide carrier is rotated from the first position to the second position. The assembly further provides means for securing the blade guide carrier in the second position to provide accurate alignment and prevent rotation of the carrier during use.
