Abstract: This invention concerns an integrated method for providing individuals with current assessments of genetic risk based on genetic tests and genomic research. While existing genetic tests can provide an estimate of genetic risk for many common diseases, genomic research is expected to provide a large number of new genetic test that will enable more definitive assessments of an individual's risk of disease. The invention provides an integrated method and systems for providing individuals with a current assessment of their genetic risk based on such advances. This method has utility in enabling individuals and healthcare professions to use genetic tests in important healthcare and lifestyle decisions.

Abstract: A non-slip support shoe for attachment to the end of any crutch or other walking aid comprises an attachment cylinder for attaching the shoe to the bottom of the crutch or walking aid; a pair of strip leaf springs, at least one of which is connected to the attachment cylinder; and a rubber sole provided on the bottom surface of a lower one of the strip leaf springs. In operation, when the maximum weight of a body is exerted on the crutch or walking aid, the strip leaf springs change configuration (i.e., flatten) so that the entire sole located on the lower strip leaf spring contacts the ground, thereby preventing slippage during use of the crutch or walking aid. Once the maximum weight of the body is removed, the strip leaf springs return to their original configuration so as not to interfere with the angled forward and backward positions of the crutch during use.

Abstract: A cursor control device for use with a three-dimensional stereoscopic image display system comprises a housing defining a volume corresponding to a displayed three-dimensional volume, and a joystick operable by the user for moving and positioning a cursor in the displayed three-dimensional volume. The joystick has a knob which is movable within the volume defined by the housing so as to designate desired positioning and movement of the cursor within the displayed three-dimensional volume. There is, at any given time, both positional and movement congruency between the position and movement of the knob and position and movement, respectively, of the cursor.

Abstract: A three-dimensional imaging system for obtaining a three-dimensional image of an object being scanned ultrasonically comprises a source arrangement for sequentially transmitting ultrasonic energy toward the object in successive directions in a first scanning plane, followed by sequential transmission of ultrasonic energy toward the object in successive directions in successive scanning planes parallel to the first scanning plane, a detector arrangement for receiving reflected energy and converting the reflected energy to electrical signals, and a processor for processing the electrical signals to develop reconstructed image data of the object, the reconstructed image data comprising forward projections of the object into a left image plane and a right image plane to form left and right images, respectively, the left and right images forming a stereo pair for composite display by a display unit.

Abstract: An array of radiation detectors is rotated about one or more sources of fan-shaped substantially planar radiation beams which are, in turn, rotated in the opposite direction about a three-dimensional body such that substantially parallel paths are defined between given individual detectors of the array and the radiation sources during the course of their oppositely directed movements. Radiation absorption measurements are taken along thusly defined plural intersecting sets of substantially parallel paths within a desired cross-section of the three-dimensional body to provide data for use in computing and displaying a constructed visual image of structures having different radiation absorption coefficients within the cross-section.

Abstract: Television (TV) scanning with improved resolution is obtained by implementation into a conventional TV scanning arrangement of a vertical drive signal modifying circuit which modifies vertical drive signals prior to their being provided as an input to the conventional TV scanning arrangement. Processing of the vertical drive signals results in the generation of various time delay signals which, when logically combined in accordance with the present invention, result in the generation of modified vertical drive signals. As a result of application of the modified vertical drive signals to the conventional TV scanner arrangement, the number of fields making up the conventional interlace pattern is multiplied by an integral factor greater than one.
