Title: Automatic recognition of characters on structured background by combination of the models of the background and of the characters
Inventor: STRINGA LUIGI
IPC: G07D7/12
Filed: 2000-06-06
Abstract: The invention relates to a process for obtaining by electronic means the automatic recognition of characters, even if printed in a variable position on a highly contrasted structured background drawing.      The process consists in firstly producing a model of the background, obtained by capturing with an electronic camera the images of several samples, on which images there is only the background. Thereafter, the models of the symbols (for example alphanumeric characters) to be recognized are produced, either capturing the images of a set of characters printed on white background, or using the commercially available computer files of the characters of the chosen fonts.      At the time of recognition, the position of each of the characters to be recognized is firstly measured with respect to the position of the printing of the drawing of the background. Each character to be recognized is thereafter compared with models obtained by combining the models of the symbols with the model of the background, with the same relative position of the unknown character. Recognition of the character together with background is therefore achieved by comparison with models of the characters combined with the same background in the same position, using any well-known recognition techniques.

Inventor: KELLY LEONARD
IPC: A61B1/31
Filed: 2000-10-17
Abstract: A device for moving a tool along a passage, particularly for use in medical procedures, has two different aspects. In one aspect, a tool, e.g. a colonoscope, is surrounded by a sheath. The sheath has an inflatable region for engaging the passage wall, e.g. a colon. An annular extension region of the sheath is provided which becomes part of the inflated inflatable region thereby increasing its length as the fluid pressure acts against a head of a tool to draw the tool along the passage. The annular extension region has sheath parts which face one another by their relative orientation caused by crumpling of the extension region, or the sheath parts are provided by folded portions. The extension region moves together with the tool as the sheath parts sequentially move into the inflated inflatable region.  This structure avoids the use of an inner wall of the sheath which would move upon and in contact with the tool during use thereby producing resistance to movement of the device along the passage. In the other aspect, after inflation of the inflatable region of the sheath, inflation pressure acts against an inflatable head carried at the distal end region of the tool to draw the tool along the passage. The inflatable head, in medical use, may reduce discomfort, and may be deflated for easy removal of the device.

Filed: 2000-11-23
Abstract: A stator vane frame assembly including an outer structure ring (34), an inner structure ring (36), a set of discrete vanes (22) each connecting the outer structure ring (34) and the inner structure ring (36) forming an inner and outer platforms with neighboring vanes (22) defining a set of flow paths, a set of sealing members (30, 32, 58, 70) contoured to a set of gaps (60) between the set of vanes (22) disposed to sealing the gap (60). A method for applying a sealing member (30, 32, 58, 70) to the gaps (60) between a platform formed resulting from the coupling between vanes (22) including affixing a set of stator vanes (22) on an inner frame and an outer frame, and sealing a set of sealing members (30, 32, 58, 70) on the backside surface of a stator vane frame. The discrete nature of individual vane blade sealed by the sealing members (30, 32, 58, 70) renders the stator vane frame assembly to add a damping effect which increases the fatigue life of the vane (22), and permits the use of lower strength, lighter, and less expensive material.

Title: Magnetically coupled autonomous battery equalization circuit
Inventor: RODEN GAREY GEORGE
IPC: H02J7/00
Filed: 2000-12-05
Abstract: A battery equalization circuit for equalizing charge between at least first and second series-connected batteries, where each battery has a positive end and a negative end, with the positive end of the second battery coupled to the negative end of the first battery at a common node, and using: a switching circuit connectable to the positive end of the first battery at a positive node and the negative end of the second battery at a negative node; a transformer having first and second magnetically coupled windings, each with a first end defining a polarity of the winding and a second opposing end; and a transformer reset circuit coupled from the windings of the transformer to the positive and negative nodes. The switching circuit acts to simultaneously couple the first and second windings in parallel with the first and second batteries, respectively, in the same polarity such that a charge is transferred between the first and second batteries as a function of a charge imbalance therebetween. The transformer reset circuit couples one of the first and second windings in parallel with one of the first and second batteries in an opposite polarity to direct reset current from the transformer to that battery to decrease the charge imbalance therebetween.

Title: Concurrent evaluation of multiple filters with runtime substitution of expression parameters
Inventor: LEATHERS BURTON
IPC: G06F17/00
Filed: 2000-12-29
Abstract: The invention introduces a mechanism to overcome the limitations of the existing methods for analysing large amounts of data. The end-user selects the various filter expression types and any required parameters used to condense the data, and this allows interactive selection of the most interesting ones as well as the ability to vary parameters for those filter expressions requiring them. These selected filter expressions are used to produce filtered views of the data in the cross-tabulations, so that the end-user gains a better grasp of the significant attributes of the data by having less important data either omitted, or aggregated into arbitrary groups. Because all of the permitted filter expressions are pre- computed there are significant improvements in usability and effectiveness. Further, since the pre-computation of these quite complex functions is performed concurrently there is potential for significant savings in processing resources.

An approximately 3.75-5 centimeter (1.5 - 2 inch) anterior incision is made in line with the femoral neck. The femoral neck is severed from the femoral shaft and removed through the anterior incision. The acetabulum is prepared for receiving an acetabular cup through the anterior incision, and the acetabular cup is placed into the acetabulum through the anterior incision. A posterior incision of approximately 2.5 - 3.75 centimeters (1 - 1.5 inches) is generally aligned with the axis of the femoral shaft and a tubular posterior retractor is utilized to provide access to the femoral shaft through the posterior incision. Preparation of the femoral shaft including the reaming and rasping thereof is performed through the posterior incision and posterior retractor. A bag element is utilized to cover the femoral stem and keep it clean as it is inserted through the posterior incision. Procedures being performed through the posterior incision may be observed through the anterior incision and vice versa. The acetabular liner and femoral head are inserted through the anterior incision and operably positioned. Novel instruments including an osteotomy guide; an awl for locating a posterior incision aligned with the axis of the femoral shaft; a tubular posterior retractor; a selectively lockable rasp handle with an engagement guide; and a selectively lockable provisional neck are utilized to perform the total hip arthroplasty of the current invention.
