Filed: 1990-08-01
Granted: 2001-05-01
Abstract: A catheter device and a method for using same to facilitate removal of obstructive material in a human body channel. The catheter comprises an elongated body with a distal end portion adapted to be inserted within the channel and a proximal end portion. A lumen, extending lengthwise through said catheter body, supports a guidewire having a distal end along which the catheter body can be moved within the channel. A series of parallel, closely spaced fiber members extend through the catheter body from its proximal end and terminate near a distal end face of said catheter. Laser energy supplied at the catheter's proximal end is transmitted along the fiber members and is emitted forwardly therefrom at the catheter's distal end face. In one embodiment the catheter has a tapered nose portion for displacing obstructive material in the body channel before the emission of laser energy. In another embodiment, the fiber members are movable longitudinally in unison to sever and trap obstructive material which is removed from the body channel.

Title: Apparatus and method for massaging the back
Inventor: GILLEN JOHN F JR
IPC: A61H23/04
Filed: 1992-07-08
Granted: 1996-12-03
Abstract: The apparatus comprises a pad and a sequential pressure device that includes a pneumatic system and a control system.  The pad comprises a plurality of adjacent chambers extending transverse to the pad's longitudinal centerline and has a lower section with at least two chambers and an upper section with at least three chambers.          Two adjacent chambers of the lower section have approximately the same transverse cross-sectional area for about their lengths.  Each chamber of the upper section includes a right portion, a left portion and an intermediate portion which has a narrowed center portion of reduced cross-sectional area connecting with the right and left portions.  Inflation of an upper section chamber causes expansion of the right, left and intermediate portions thereof with a void created about the narrowed intermediate portion.  The method makes use of the apparatus to massage the back of a patient placed in a supine position on the pad to mobilize the spine and stretch and relax the musculature and soft tissue of the back while avoiding placement of undue pressure on the thoracic vertebrae portions of the spine which are positioned above the intermediate portions of the chambers of the pad upper section.

Title: Plural component delivery system
Inventor: LANGEMAN GARY D
IPC: B05B7/32
Filed: 1993-10-01
Granted: 2004-05-04
Abstract: An apparatus and method for mixing and delivering plural liquid components in a selected volume ratio. For each component, a separate motor drives a separate rotary gear pump that delivers the component to a common mixing and delivery device (spray gun). The speed of each motor, and correspondingly the volume of fluid delivered by that pump, is determined by a respective programmable computer. The individual computers are interlinked, with one master computer and the rest slave(s).  Desired motor speeds are input into the computers in a selected ratio. A change in the speed of the master motor therefore produces a corresponding change in the speed of a slave motor according to the ratio. Actual motor speed is monitored and transmitted to the respective computer for feedback control. A simple manual ratio test is provided for calibration of the system. Each pump is magnetically coupled to its respective motor drive shaft.

Patent CA-2117587-C (CA)
Title: System for adaptively reducing noise in speech signals
Inventor: SOLVE TORBJORN W
IPC: G10L11/02
Filed: 1994-08-30
Granted: 2004-12-07
Abstract: A method and system are provided for adaptively reducing noise in frames of digitized audio signals that may include both speech and background noise. Frames of digitized audio signals are processed to determine what attenuation (if any) should be applied to the current frame of digitized audio signals. Initially it is determined whether the current frame of digitized audio signals includes speech information, this determination being based upon an estimate of noise and on a speech threshold value. An attenuation value determined for the previous audio frame is modified based on this determination and applied to the current frame in order to minimize the background noise which thereby improves the quality of received speech. The attenuation applied to the audio frames is modified gradually on a frame-by-frame basis, each sample in a specific frame is attenuated using the value calculated for that frame. The adaptive noise reduction system may be advantageously applied to telecommunication systems in which portable radio transceivers communicate over RF channels because the adaptive noise reduction technique does not significantly increase data processing overhead.
