Abstract: A time difference .DELTA. ~ between the arrival of acoustic signals from sound sources to microphones 1, 2 is detected from output channel signals L, R form microphones 1, 2. By Fourier transform, the signals L, R are divided into respective frequency bands L(f1) - L(fn), R(f1) - R(fn). Differences .DELTA. ~ i (i = 1, 2,...n) in the time-of-arrival of L(F1) - L(fn) and R(f1) - R(fn) to the mocrophones 1, 2 as well as a signal level difference .DELTA. Li are detected. L(f1) - L(fn), R(f1) - R(fn) are divided into a low range of fi < 1 / (2 .DELTA. ~), a middle range of 1 / (2 .DELTA. ~) < fi < 1 / .DELTA. ~, and a high range of fi> 1 / .DELTA. ~. Utilizing .DELTA. ~ i for the low range, .DELTA. Li and .DELTA. ~ i for the middle range and .DELTA. Li for the high range, a determination is made from which sound source L(fi), R(fi) are oncoming to deliver outputs separately for each sound source. The output are subject to an inverse Fourier transform for synthesis separately for each sound source.

Abstract: The torque limiter described herein is a device for preventing the transmission of torque from a drive source to a torque responsive element when a predetermined torque limit has been reached. The device also provides subsequent mechanical indication of said torque overload event. The device operates by transmitting torque between two axial members, a drive member and a driven member, having a plurality of balls therebetween with the balls engaged within precisely shaped sockets contained within each axial member. As excess torque occurs, the plurality of balls cause the driven member to axially displace with respect to the drive member, engaging a set of teeth contained on the driven member with a second set of teeth aligned with the first set of teeth and restrained within the housing, thereby preventing torque transmission. The second set of teeth is allowed to rotate, relative to the housing, through a predetermined angle into a torsionally compliant mount before contacting substantially rigid structure. This allows the teeth to engage smoothly at higher operating speeds. Indication of the torque overload event is achieved by detecting the limited motion of the second set of teeth relative to the housing with a slidably mounted plunger within the housing and axially located by a detent in the member containing the second set of teeth.

Title: Noise reducing diffuser
Inventor: AWAD ELIAS A
IPC: F16L55/02
Filed: 1998-07-24
Granted: 2008-02-26
Abstract: A noise reducing diffuser which reduces the sound energy created by a pressurized gas while it is being expelled through a nozzle. The diffuser consists of an elongated enclosure with openings at each end that is attached to the output of the gas nozzle. The dimensions of the enclosure, particularly its distance from the sound source, effective diameter and length, are chosen to specifically eliminate audible noise created by the escaping gas by conversion of a portion of the longitudinal component of the sound energy to an increased radial component that can then be dissipated by repeated contact with the wall of the elongated enclosure.

At its free or open end the cylindrical member has an  outwardly flared portion and flow inducing protrusions are provided adjacent  that open end to help impart rotational flow to fluid moving within the seal  cavity. Flow inducing vanes or vents may also be provided within the protect or at the junction of the ring and cylindrical members. Heavy abrasives are mov ed along the interior of the protector to exit at the free end and to then be centrifuged outwardly and away from the seal. Air is centrifuged inwardly towards the back of the seal where it will do no harm.

Abstract: A method for imaging an organ or internal structure within a body to obtain three-dimensional reconstruction of the organ includes steps of providing an intraluminal ultrasound imaging system (23) capable of obtaining echographic images of the surrounding of a catheter imaging tip (22) located inside the body of a patient. The intraluminal ultrasound catheter imaging tip (22) is positioned within a region of interest (97) inside the body of the patient and a plurality of echographic images are obtained during deliberate movement or pull-back of the catheter (21), each image corresponding to an echographic data set. The position of the catheter axis with respect to each echographic data set obtained during pull-back is recorded. The recorded position of the catheter tip (22) can be used to calculate a catheter pull-back trajectory in three-dimensional space. The images are stacked around the catheter pull-back trajectory by positioning the origin of a first image at a first recorded position, and positioning subsequent images at their respective distances from the first image, wherein each echographic data set is positioned so that the catheter axis is aligned with the catheter pull-back trajectory.

Title: Dialysis catheter having rigid and collapsible lumens and related method
Inventor: PALESTRANT AUBREY M
IPC: A61M25/00
Filed: 1997-11-26
Granted: 2007-04-10
Abstract: A multiple-lumen catheter (10) includes a first generally-cylindrical flexib le lumen (12) extending between a first distal end (14) and a second proximal end (16); the first lumen is sufficiently rigid to maintai n its generally-cylindrical shape when negative pressure is applied thereto for aspirating fluid from the blood vessel. A second flexible lumen (18) also extends between a first distal end (20) and a second proximal end (22) alongside the first lumen. The first distal end of the second lumen is sufficiently pliable to collapse and flatten in the absence of any positive fluid pressure applied to the second lumen; upon the application of a positive fluid pressure to the second lumen, the collapsible first distal end of the second lumen expands and assumes a generally-cylindrical shape for introducing fluid into the blood vessel. The first collapsible end of the second lumen can extend beyond the first non-collapsible end of the first lumen for introducing fluid into the blood vessel through the second lumen at a point spaced apart from the first end of the first lumen. In hemodialysis applications, the first lumen is used to aspirate blood, and the second lumen is used to return cleansed blood.

Granted: 2004-01-13
Abstract: A method of automated data collection, analysis and reporting is described. A plurality of questionnaires each consisting of a number of questions are stored in a database. New questionnaires may be added or existing ones modified by contacting the database by telephone. In use, a respondent accesses the database by telephone. Once the respondent is connected, the respondent enters a code which identifies the respondent and the questionnaire to be completed. The questions of the questionnaire are "read" to the respondent by an interactive voice response which then prompts the respondent to enter a response. The response is recorded and the next question is then "read". The process is continued until the questionnaire has been completed. The results are then immediately analyzed and reported to a third party. For example, the responses of the latest respondent may be compared to the responses of all previous respondents or previous responses of the same respondent.      The report may be sent automatically, for example, by fax.
