Title: Aerodynamic noise reducing structure for aircraft wing slats
Inventor: GLEINE WOLFGANG
IPC: B64C21/04
Filed: 2001-04-17
Abstract: A hollow expandable and contractible displacement element is secured onto the concave rear surface of a slat facing the leading edge of an aircraft wing. A bleed air line supplies engine bleed air into the hollow displacement element to selectively expand or contract the displacement element, which is preferably elastically expandable. When the slat is extended, the displacement element is expanded to fill-out the concave cavity on the rear surface of the slat so as to prevent formation of a vortex in the slat air gap and thereby to reduce aero-acoustic noise. When the slat is retracted, the displacement element is contracted to be conformingly accommodated in the sickle-shaped space between the slat and the leading edge of the wing.
Patent CA-2345965-A1 (CA)
Title: Method and device for measuring access flow
Inventor: NILSSON EDDIE
IPC: A61M1/16
Filed: 1999-10-22
Abstract: An arterial needle removes blood from the access to an extracorporeal circui t comprising a dialyzer and a venous needle returns the blood to the access site. Blood passes along one side of the membrane of the dialyzer and dialys is fluid along the other side. The concentration (Cd norm and Cd rev) of urea i n the dialysate emitted from the dialyzer is measured with the needles in the normal position and in a reversed position. The access flow rate before the arterial needle is calculated according to the formula: Cd norm / Cd rev = 1  + Keff/Qa in which Keff is the effective clearance of the dialyzer and Qa is t he access flow rate.
Patent CA-2347182-A1 (CA)
Title: Fluid circuit components based upon passive fluid dynamics
Inventor: SPUTE MARK K
IPC: B01F15/02
Filed: 1999-10-13
Abstract: Methods of controlling fluid flow through microchannels by use of passive valves or stopping means in the microchannels are presented. The passive valves act as pressure barriers impeding flow of solution past the stopping means until enough force is built up to overcome the force of the pressure barrier. Well planned use of such stopping means acting as passive valves allows the flow of fluids through microchannels to be regulated so as to allow fluids to be mixed or diluted after being introduced via a single channel, or to be split into multiple channels without the need for individual pipetting. Flow through the multiple channels can be regulated to allow a series of sister wells or chambers to all fill prior to the fluid flowing beyond any one of the sister wells or chambers. The filling of sister wells or chambers in this manner allows all wells or chambers to undergo reactions in unison. The use of air ducts to prevent trapping of air in the microchannels is also presented.

Filed: 2001-05-09
Abstract: A portable golf putting training device used by golfers to improve their putting stroke comprising a flexible plastic sheet with a reflective layer and guide lines both parallel to and perpendicular to the intended path of the ball. The guide lines and the reflective surface provide feedback to the golfer during the stroke as to whether (a) the club face is square to the intended path; (b) the putter has been drawn back parallel to the intended path; (c) the backswing is slow and smooth; and (d) a long follow-through has been made.  Preferably the device is made of a clear acrylic material with a protected reflective layer in which the guide lines are cut. The sheet is oblong and provided with an end-to-end longitudinally oriented target line that bisects the sheet. A spot for mounting a golf ball is marked less than half-way along the target line as measured from the backswing end. The spacing between successive transverse guide lines increases as one progresses from the backswing end to the ball mounting spot. Thereafter from the ball mounting spot to the follow-through end, the transverse guide lines are uniformly spaced.

Title: Mink-related genes, formation of potassium channels and association with cardiac arrhythmia
Inventor: GOLDSTEIN STEVE A N
IPC: C12Q1/68
Filed: 2000-04-14
Abstract: The present invention is directed to genes and gene products related to Min-K  which form ion channels and to a process for diagnosis of ion channel disorders, including long QT syndrome (LQT). For example, KCNE2 forms IKr potassium channels and is associated with LQT. LQT is diagnosed in accordance with the present invention by analyzing the DNA sequence of KCNE2 of an individual to be tested and comparing the respective DNA sequence to the known DNA sequence of a normal KCNE2 gene. Alternatively, these MinK-related genes of an individual to be tested can be screened for mutations which cause ion channel disorders, including LQT. Prediction of ion channel disorders, including LQT, will enable practitioners to prevent the disorders using existing medical therapy. This invention is further directed to the discovery that the HERG and KCNE2 (also known as MiRP1) proteins coassemble to form a cardiac IKr potassium channel.

Abstract: An RF coil suitable for use in imaging systems is provided which coil has a dielectric filled cavity formed by a surrounding conducting enclosure, the conducting enclosure preferably being patterned to form continuous electrical paths around the cavity, each of which paths may be tuned to a selected resonant frequency. The patterning breaks up any currents induced in the coil and shortens path lengths to permit higher frequency, and thus higher field strength operation. The invention also includes improved mechanisms for tuning the resonant frequency of the paths, for selectively detuning the paths, for applying signal to the coil, for shortening the length of the coil and for controlling the field profile of the coil and the delivery of field to the object to the image.

Abstract: An optical arrangement (10) provides dispersion slope compensation to a dispersion distorted input signal comprising NxM wavelength multiplexed channels. In the optical arrangement, a major dispersion compensating fiber (DCF) (14) provides a first predetermined chromatic dispersion correction value to the NxM wavelength channels.
