Abstract: A computer based system for brush writing (calligraphy) employs a stylus operable on a working surface in a brush imitating manner. A digital processor receives signals indicative of stylus strokes during operation of the stylus, and establishes, in real time, images of brushed strokes. The images of brushed strokes correspond to the brush imitating operation of the stylus and are displayed in real time or printed at a desired later time. Geometric characteristics of the images of brushed strokes vary as a function of detected parameters of stylus operation. The function is user definable through a graph screen view. A teardrop shaped drawing primitive which changes as a function of stylus operation provides images of brushed strokes of Eastern calligraphy. A line primitive which changes as a function of stylus operation provides images of brushed strokes of Western calligraphy.

Title: Wilson disease gene
Inventor: COX DIANE W
IPC: C12N9/14
Filed: 1993-10-21
Granted: 2008-09-02
Abstract: Wilson disease (hepatolenticular degeneration) is an autosomal recessive disorder of copper transport, resulting in copper accumulation and toxicity to the liver and brain. The gene (locus WND) has been mapped to chromosome 13 band q14.3. On three overlapping yeast artificial chromosomes (YACs) from this region, a sequence similar to the proposed copper binding motifs of the putative ATPase (MNK) defective in Menkes disease was identified. It was shown that this sequence forms part of a P-type ATPase gene (Wc1) that is very similar to MNK, with at least six putative metal binding domains homologous to those found in prokaryotic heavy metal transporters. This gene lies within a 300 kb region that has been identified as a likely location for WND. The gene is expressed in the liver and kidney and is a candidate for Wilson disease.

Filed: 1992-07-14
Granted: 2007-11-06
Abstract: Genetically engineered cells are provided which can serve as universal donor cells in such applications as reconstruction of vascular linings or the administration of therapeutic agents. The cells include a DNA sequence which is expressed by the cell and which codes for a protein having complement inhibitory activity and which provides protection against complement-based lysis, i.e., hyperacute rejection. In addition, the cell's natural genome is changed so that proteins encoded by either the class II or both the class I and the class 11 major histocompatibility complex genes do not appear on the cell's surface. In this way, attack by T-cells is avoided. Optionally, the cells can include a self-destruction mechanism so that they can be removed from the host when no longer needed.

IPC: B25B23/14
Filed: 1994-03-31
Granted: 1998-11-10
Abstract: Axially  extending  lobes  extend  radially  from  an internally threaded nut and form axial troughs that receive a respective axial cone mounted in the socket of a driver, the cones being rotatably driven against the lobes to apply a threading torque to the nut.  At a predetermined torque, an axial outer radial end portion of the material forming the lobe is plastically deformed, but not sheared off, thereby allowing the socket to rotate and the cones to advance against the next respective lobe.   The deformed lobe indicates to the user that the nut was properly torqued and the deformed material  does  not  shear off thereby indicating that the nut had not been tampered with. To permit relaxation, a second torquing could be done at a later time.

Title: Telephone calling with automatic billing
Inventor: GIBILISCO PAUL F
IPC: H04M15/00
Filed: 1994-06-29
Granted: 1998-09-22
Abstract: An automatic calling service is provided wherein a subscriber predefines one or more destination telephone numbers, and calls to such number or numbers are billed to the subscriber's local telephone number. Calls are made to such destination numbers through a platform that may be reached via a toll free number. The calling party identifies him/herself as a subscriber, by entering a personal identification number, to authenticate him/herself as a person entitled to make such calls. Based upon the identification provided, a determination is then made as to whether thesubscriber has stored one number, or more than one number. If one number is stored, the caller need not identify the destination number, and advantageously, that number is then dialed. If more than one number has been specified, the subscriber is prompted to provide an indication of the particular number desired. The call is then completed to the desired number. In either event, the identity of the subscriber is used to assure that the call is billed to the subscriber's local telephone number. In order to reduce the possibility of unauthorized access, a determination may also be made as to whether to call is originating from an eligible location, as by checking automatic number identification (ANI) information associated with the call.
