Title: Translating objects between software applications which employ different data formats
Inventor: SABADELL STEWART
IPC: G06F17/30
Filed: 1999-05-14
Abstract: A mechanism for translating objects between applications that use different formats is described. As described, a source object is generated using a source application. The source object is then translated to a target object in a target application. The target application having a format that is not supported by the source application. A first modification, which is not supported by the source application, is then performed to the target object. A second modification is also performed to the source object in the source application. Based on the modifications, the target object in the target application is revised to reflect the second modification to the source object without removing the first modification to the target object.

Title: Method of operating a charge coupled device in an accelerated mode, and in conjunction with an optical symbology imager
Inventor: STERN HOWARD
IPC: H04N5/345
Filed: 1999-09-10
Abstract: A method of operating a charge coupled device in an accelerated mode is provided, and in particular in connection with an optical symbology imager (10), so as to minimize variations in the position of the imager relative to the code. The CCD (93) has two horizontal shift registers, each receiving every other scan line so that the output of each horizontal shift register equals the number of scan lines for normal television signals (262). The method skips through multiple lines of image data (fig. 22), then provides a black reference signal then images a series of lines at a slower speed, these lines being the lines of interest (fig. 23) for focusing and illumination operations in the optical symbology imager. Finally, the remaining lines are passed through quickly. The imager goes back into reset mode after either normal or fast mode operation, and is thereby immediately ready to perform another scan. The fast mode operation enables the imager to obtain the approximately ten lines of image data of concern in only approximately 5.5 milliseconds, a significant time savings. This operation can be performed for some or all of the multiple optical positions.

Abstract: A method for applying hardfacing to teeth on a drill bit is disclosed. The method includes applying the hardfacing to at least one of the teeth so as to have a thickness selected to correspond to a position about exterior surface of the tooth. In one embodiment, the hardfacing thickness is increased near the crest of the tooth, and is decreased near the root of the tooth on at least one flank of the tooth. In one embodiment, the thickness is selected by controlling the powder flow rate in a plasma transferred arc welding system. In another embodiment an angle subtended by flanks of the tooth is selected to provide increased strength to the tooth, and the hardfacing is applied to the tooth to cause exterior surfaces of the hardfacing corresponding to the flanks to subtend an angle selected to provide increased penetration of the tooth through earth formations while drilling.

Abstract: Crop harvesting headers include a sickle knife having a cutter bar defining a flange projecting forwardly from the header frame structure and extending across the header frame structure with a plurality of knife guards mounted on the cutter bar at spaced positions thereon so as to project forwardly therefrom.  Each knife guard has at least one guard carrier lug for attachment to the flange by a bolt passing through a hole in the lug and a corresponding hole in the flange with a head on one end of the bolt and a nut on the other end of the bolt for clamping the lug to the flange. On crop harvesting headers of this type, it is often desirable to have the ability to change the knife guard angle to suit the crop and ground condition and this is obtained by providing a first elongate bar type shim located between the lug and the flange and a second shim located on the bolt. The shims are tapered front to rear and rear to front respectively each at the same set angle and are clamped on the bolt with the flange and the lug to hold the guard at a first angle relative to the flange determined by the set angle. In the method, the shims are reversed in position relative to the flange and the bolt to hold the lug at a second angle relative to the flange determined by the set angle and different from the first angle by an angle twice the set angle.

Abstract: A system for estimating the Net Asset Value (NAV) of a fund makes use of an MLR engine (22) to compute a multiple linear regression between historical NAVs for the fund, stored in a NAV history database 12, and corresponding histories for a series of market indexes, stored in an index history database (14).   An associations database (18) determines which market indexes are to be used for the analysis. The resultant regression coefficients are used by a NAV estimator (24) to generate an estimated current value of the fund based on current values of the market indexes, as supplied by a market index feed (16). The system provides an investor with estimated real-time values of a fund -not normally available since fund values are generally calculated only on a daily basis.
