Title: Method of identifying similarities in code segments
Inventor: GOODNOW JAMES E II
IPC: G06F11/36
Filed: 1996-01-15
Granted: 1999-09-14
Abstract: A method of analyzing a plurality of code segments to determine the similar static and dynamic features of the code segments compares the static anddynamic features of each of the code segments. Each code segment is comprised ofone or more lines of program instructions. One or more predetermined static attributes are extracted from each code segment. Each code segment is then run so that the dynamic attributes of the code segment can be determined. The dynamic attributes are extracted from each code segment and a distrance function is computed which is based on the extracted static and dynamic attributes for a given pair of code segments. The distance function produces a distance measurement which indicates the relative degree of similarity between the given pair of code segments.

Title: Segmented wood chip cracking roll
Inventor: BIELAGUS JOSEPH B
IPC: B27L11/00
Filed: 1994-11-08
Granted: 1999-06-01
Abstract: A wood chip cracking device (20) for use in papermaking employs closely spaced, oppositely rotating rolls (24, 26) which have pyramid-shaped projections (38) on the roll surfaces (32, 34). This chip destructuring apparatus (20) is rendered readily serviceable with minimal downtime by constructing the roll surface (32, 34) of removable segments (25) which are bolted to a central rotatable shaft (46). The segments (25) are sized so they can be lifted by a service man. As damage to the roll surface (32, 34), such as by exposure to tramp metal, is typically limited to a single segment, service and repair of the roll (24, 26) is expedited by permitting removal of a single damaged segment without removing the remaining undamaged segments (25). Each segment is bored for twelve bolts (72) and is affixed to the inner shell by twelve recessed bolts (72). The surface segments (25) allow the surface to be replaced without removing the rolls (24, 236) from the frame (30) of the wood chip cracking device (20).

Alternatively,  a  tool  having  protrusions  contacting portions of the inner surface of the mold is inserted into the mold, before or after insertion of the first ingredients, the first ingredients are frozen, the tool is removed,  and the second ingredients then are added and frozen.   In another embodiment,  a first flavor or color is sprayed onto the inner wall of the mold in a pattern and frozen.

Abstract: An efficient, lossless, continuous-resolution representation (the "PM representation") of highly detailed geometric models for. computer graphics specifies a succession of progressively more detailed polygonal meshes (i.e., "progressive meshes") as a base polygonal mesh and a sequence of complete mesh refinement transformations (e. g., the vertex split transformation) that approximate the model at progressively finer levels of detail. Procedures for storing and transmitting geometric models using the PM representation address several practical problems in computer graphics: smooth geomorphing of level-of-detail approximations, progressive transmission, mesh compression, and selective refinement. An optimized mesh simplification procedure constructs the PM representation of a model from an arbitrary polygonal mesh, while preserving the geometry of the original mesh as well as its overall appearance as defined by its discrete and scalar appearance attributes such as material identifiers, color values, normals, and texture coordinates. In particular, the PM representation and these procedures preserve discontinuity curves such as creases and material boundaries of the geometric model.

Abstract: An insulated container (12) for carrying goods such as fish is provided. The insulated container (12) includes a cover (14) and an open-topped box (16). The box (16) includes a bottom (26), two end walls (22, 24), and two bowed side walls (18, 20). Fillets lie in the corners where the bowed side walls and bottom meet. Longitudinal drainage ribs (40) extend along the bottom (26) between transverse platforms (42, 44). Indentations (28, 30, 32, 34) formed on the outer surface of the bowed container (12) define regions for receiving straps.

Granted: 2001-04-24
Abstract: A wideband semiconductor electro-absorption optical modulator including a semiconductor core shorter in absorption-peak wavelength than a wavelength of optical signal, and an electrode for applying an electric signal to absorb the optical signal by shifting the absorption-peak wavelength to a long wavelength region when a voltage is applied, wherein an electric signal input port and an electric signal output port are disposed so that the electrode is constructed in the form of a traveling-wave electrode, and a total thickness of non-doped layers including the semiconductor core is reduced to decrease a driving voltage.  Degradation of optical modulation bandwidth and reflection characteristics of the electric signal caused by mismatching of characteristic impedance to an outer circuit are reduced by decreasing an interaction length of the electric signal and the optical signal.  Further, mismatching of characteristic impedance is corrected by adjusting a doping concentration of a p-type or n-type doped layer located above or beneath the semiconductor core.
