Information indicative of one or more migration candidates corresponding to one or more system components in a source system may be collected. A migration strategy may be determined at least partially based on the information indicative of one or more migration candidates. The one or more migration candidates may be mapped to one or more system components of a target system. One or more scripts configured to copy system data and/or application data corresponding to the one or more system components in the source system for migration to the target system may be generated.

Abstract: A head and neck restraint system includes a vertical support and a head and neck restraint assembly coupled to the vertical support. The head and neck restraint assembly includes a pair of spaced members coupled to the vertical support. The pair of spaced members have a spring memory that permits movement of one of said members toward and away from the other member or movement of both of said members toward and away from each other. One or more spring biased wedges avoid the spring memory from returning one or both of the spaced members to a starting position after movement of one of the members toward the other member or movement of both of the members towards each other.

Abstract: Systems and methods for modeling a prospective systems migration between server systems are provided. Performance data associated with a plurality of applications in a first server system may be collected. A selection of a set of applications in the plurality of applications to migrate to a second server system may be processed. Combined performance data that estimates how the set of applications will perform on the second server system may be computed using at least some of the performance data. Based on the combined performance data, indications as to whether the set of applications should be migrated to the second server system may be provided.

Abstract: The system has a male tubing fitting extending along a longitudinal axis. The male tubing fitting has a first internal bore and an end portion including a male plug. The system also has a female tubing fitting that has a second internal bore configured to receive the male plug. Also, the system has a collar disposed about the male tubing fitting and positioned to slide freely along the longitudinal axis from a first position to a second position. In the first position the male and female tubing fittings are unlocked with respect to each other such that the male plug is removably insertable into the second internal bore of the female tubing fitting. In the second position the male and female fittings are locked with respect to each other such that the male plug is prevented from being removed from the second internal bore of the female tubing fitting.

Abstract: Gradient index (GRIN) lens chips for optical connections, and related methods of creating GRIN lens chips are disclosed. Each GRIN lens chip may include at least one GRIN lens and a GRIN lens holder for aligning the GRIN lens in an optical connection. When creating a GRIN lens chip, a shaped substrate may be provided including a GRIN lens holder and at least one GRIN groove for securing and aligning the GRIN lens relative to the GRIN lens holder. The GRIN lens may be part of a GRIN lens rod. By freeing the GRIN lens holder from the shaped substrate, the GRIN lens holder may include a fiber mating surface and a terminal mating surface. The fiber mating surface and the terminal mating surface may be used to align the GRIN lens holder in the optical connection.

Abstract: Gradient index (GRIN) lens chips and associated small form factor optical arrays for optical connections, and related fiber optic connectors are disclosed. By aligning GRIN lenses within a GRIN lens chip, a more precise and reliable alignment may be achieved with respect to optical fibers than if a single conventional ferrule is utilized to align and secure both GRIN lenses and optical fibers. The GRIN lens chip may include a GRIN lens received and thereby aligned within a groove disposed between a fiber end and a terminal end of a GRIN lens holder body. The optical fibers may also be received and thereby aligned within a groove of a ferrule body. In this manner, when the GRIN lens chip containing the GRIN lenses is aligned with a ferrule body containing the optical fibers, then the GRIN lenses may be precisely located relative to the optical fibers.

Abstract: Methods and apparatus are provided for forming an initiation flaw (111) in the surface (114) of a glass sheet or glass ribbon (13). The initiation flaw (111) is used in connection with a laser light beam (121) and a cooling area produced by a cooling nozzle (119) to from a score line (115) in the surface (114) of the sheet or ribbon (13). The initiation flaw (111) is formed by a mechanical scoring head (20) which is carried by moving carriage (14) and which undergoes retrograde motion (19) relative to the carriage (14) so as to increase the time available for forming the initiation flaw (111).

Abstract: A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.
