Abstract: Investment-casting shells are disclosed that have at least one cluster of individual club-head casting molds for casting thin-walled, steel or steel-alloy club-heads at high process yield and low material usage. The shells have respective combinations of cluster configuration and number, gating, and runners, as determined systematically. Some shell configurations include a cluster of at least ten casting molds for respective club-heads each (a) having a head-volume less than 400 cm3, (b) defining at least one club-head wall having a thickness of less than 0.8 mm, and (c) defining at least one respective gate. The cluster is configured to produce a cast-product yield of greater than 80% at a material usage of less than 1,000 g, including process losses, per cast club-head. Also, at least one runner connects the gates together.

Abstract: Certain disclosed embodiments concern making sports equipment, such as golf club heads, using polishing marks to facilitate removing material from as-cast work pieces to produce a final thickness within a desired specification, such as 0.6 millimeter or less ±0.05 millimeter. At least one polish mark, more typically plural polish marks, is formed into an outer surface of an as-cast article to a depth selected to provide a final product thickness subsequent to polishing that is ±0.05 millimeter of a final desired thickness. The golf club head or component is then polished at least once to remove club head material substantially corresponding to the depth of the at least one polish mark. The method may further comprise joining the club head to a shaft.

Abstract: Investment-casting shells are disclosed that have at least one cluster of individual club-head casting molds for casting thin-walled, titanium alloy club-heads at high process yield and low material usage. The shells have respective combinations of cluster configuration and number, gating, and runners, as determined systematically. Some shell configurations include a cluster of at least ten casting molds for respective club-heads each (a) having a head-volume greater than 400 cm3, (b) defining at least one club-head wall having a thickness of less than 0.8 mm, and (c) defining at least one respective gate. The cluster is configured to produce a cast-ptoduct yield of greater than 80% at a material usage of less than 600 g, including process losses, per cast club-head. Also, at least one runner connects the gates together.

Abstract: Methods and systems for defining and distributing network data collection rule sets and for filtering messages using the rule sets are disclosed. Message-based filter criteria are automatically deduced from CDR-based filter criteria and downloaded to site collectors. The site collectors implement rule changes on-the-fly using a table-driven system. The message-based rule sets downloaded to the site collectors are supersets of the messages required by multiple different network monitoring applications. As a result, non-redundant, multi-application data streams are sent across the service provider's internal network, resulting in efficient bandwidth utilization.

Abstract: Methods and systems for dynamic, rules-based peg counting are disclosed. According to one method, a user creates peg counter definitions using a rules-based language accessible via a graphical user interface. The peg counter definitions are downloaded from an administration server to network monitoring site collectors. The site collectors automatically detect the new peg counter definitions and begin using the new peg counter definitions without ceasing existing peg counting. Peg counter software on the site collectors periodically sends peg counter instances to a data gateway server. The data gateway server aggregates the peg counter instances generated by the various site collectors into system wide peg counter instances.

Abstract: Database-driven methods and systems for database driven real time call tracing are disclosed. Signaling messages are copied from signaling link interface modules. The copied messages are sent to a database. A server located remotely from the database sends a query to the database for a real time call trace. The database is searched for messages that match the search criteria. If no messages are located in the historical data stored in the database, data entering the database is analyzed in real time.

Abstract: A color wheel assembly comprises a color wheel and a fixing ring. The color wheel comprises an annular disc and a plurality of filter lenses surrounding the annular disc. The filter lenses are attached to one another with an adhesive material. The fixing ring secures the color wheel from a top and a bottom of the color wheel. Thereby, when the color wheel rotates at high speed in a high-temperature atmosphere, the filter lenses, secured by the lower ring and the upper ring, remains securely attached to one another.
