Title: Analysis of auscultatory sounds using single value decomposition
Inventor: TEWFIK AHMED H
IPC: A61B7/00
Filed: 2004-10-19
Abstract: Techniques are described for analyzing auscultatory sounds to aid a medical professional in diagnosing physiological conditions of a patient. A data analysis system, for example, applies singular value decomposition to auscultatory sounds associated known physiological conditions to define a set of one or more disease regions within a multidimensional space. A diagnostic device, such as an electronic stethoscope or personal digital assistant, applies configuration data from the data analysis system to generate a set of one or more vectors within the multidimensional space representative of auscultatory sounds associated with a patient. The diagnostic device outputs a diagnostic message associated with a physiological condition of the patient based on the orientation of the vectors relative to the disease regions within the multidimensional space.

Inventor: SPIESS PETER A
IPC: B66B13/30
Filed: 2006-10-19
Abstract: The present invention provides an elevator door system (1) comprising, a motor (12), a vertical axis (10), a door (2) attached at a first end to the vertical axis for winding and unwinding thereupon. Force transmission means (14) interconnect a second end of the door (2) and compensation means (20) whereby the motor (12) simultaneously drives the vertical axis (10) and the compensation means (20) and wherein the compensation means (20) has variable diameter. In use, as the door (2) is unwound from the vertical axis (10), the force transmission means (14) is simultaneously wound upon the compensation means (20). Hence, not only is a thrust exerted on the door (2) by the vertical axis (10) but a drag is exerted thereupon by the force transmission means (14). Furthermore, the compensation means (20) has a variable diameter to compensate for, amongst other things, the changes in the diameter the door (2) wound on the vertical axis (10). Hence, the tension in the force transmission means (14) and the door (2) can be kept substantially constant during operation.

Title: Alignment plate for wiring device
Inventor: ODDSEN DENNIS A
IPC: H02G3/14
Filed: 2005-05-20
Abstract: There is disclosed structure which overcomes the difficulties encountered with respect to mounting wiring devices such as a receptacle and/or a switch to a box and then attaching a wall plate. Some of the difficulties encountered are positioning the wiring devices to be in alignment with each other, locating the wiring devices to be parallel to each other, adjusting the spacing between the different devices to be equal and uniform and fixing all of the devices to be flat against the wall. These deficiencies are overcome by an alignment plate having a single centrally located opening sized to receive one of more wiring devices and a set of alignment pins for each wiring device. Each set of alignment pins on the alignment plate is located on a vertical axis which defines the center for a wiring device and each wiring device has openings for frictionally receiving and holding captive a set of alignment pins. The alignment pins accurately position, align and locate all of the wiring devices relative to each other. Thereafter the alignment plate and wiring devices can be attached to a box by means of mounting screws and a wall plate can then be positioned around the wiring devices without further adjustment.
