Patent number: 6171820Abstract: Disclosed is a rapid and facilitated method of producing from a parental template polynucleotide, a set of mutagenized progeny polynucleotides whereby at each original codon position there is produced at least one substitute codon encoding each of the 20 naturally encoded amino acids. Accordingly, there is also provided a method of producing from a parental template polypeptide, a set of mutagenized progeny polypeptides wherein each of the 20 naturally encoded amino acids is represented at each original amino acid position. The method provided is termed site-saturation mutagenesis, or simply saturation mutagenesis, and can be used in combination with other mutagenization processes, such as, for example, a process wherein two or more related polynucleotides are introduced into a suitable host cell such that a hybrid polynucleotide is generated by recombination and reductive reassortment.Type: GrantFiled: February 4, 1999Date of Patent: January 9, 2001Assignee: Diversa CorporationInventor: Jay M.

Patent number: 6111406Abstract: A method for assessing write element performance in a combined magnetic head that also includes a magneto-resistive (MR) read element for a data storage drive includes exciting the write element with a square wave immediately after lapping the head during manufacture, before mounting the head for operation in the drive. The write element generates an output signal, and the output signal is detected by the read element and then used to determine whether the write element is defective. By using a square wave, temperature gradients in the head and inductive pick up is avoided, thereby facilitating the use of the read element as a test sensor.Type: GrantFiled: August 28, 1997Date of Patent: August 29, 2000Assignee: International Business Machines CorporationInventors: Glen Adam Garfunkel, Donald E.

Patent number: 6081409Abstract: A magneto-resistive read head having a "parasitic shield" provides an alternative path for currents associated with sparkovers, thus preventing such currents from damaging the read head. The parasitic shield is provided in close proximity to a conventional magnetic shield. The electrical potential of parasitic shield is held essentially equal to the electrical potential of the sensor element. If charges accumulate on the conventional shield, current will flow to the parasitic shield at a lower potential than would be required for current to flow between the conventional shield and the sensor element. Alternatively, conductive spark gap devices are electrically coupled to sensor element leads and to each magnetic shield. Each spark gap device is brought within very close proximity of the substrate to provide an alternative path for charge that builds up between the sensor element and the substrate to be discharged.Type: GrantFiled: October 28, 1997Date of Patent: June 27, 2000Assignee: International Business Machines CorporationInventors: Timothy Scott Hughbanks, Neil Leslie Robertson, Steven Howard Voldman, Albert John Wallash

Patent number: 5999286Abstract: This invention includes a path-based method and system that restore a distributed telecommunications network (90) from a failure condition (92). First, the method and system notify all the network nodes (22, 24, 26, 28) of the fault of a link (12). Next, an alternate route finding phase occurs for finding alternate paths (S-T1-T4-D) to reroute the disrupted traffic. For finding alternate paths (S-T1-T4-D), the alternate route finding phase includes sending messages (70, 100) throughout the distributed telecommunications network. Upon finding some alternate paths (S-T1-T4-D), the method and system send connect commands (100) to make the necessary cross connections in the distributed telecommunications network nodes (22, 24, 26, 28) that are on the alternate paths (S-T1-T4-D). Throughout the distributed network restoration process, the method and system synchronize (62) the distributed telecommunications network nodes to avoid possible race conditions among the nodes.Type: GrantFiled: January 9, 1997Date of Patent: December 7, 1999Assignee: AlcatelInventor: S.
