A method and apparatus are provided for encapsulating a workpiece in a material having a lower melting temperature than that of the material for the workpiece to form an encapsulated block of standardized size and shape which may be mounted in a standardized fixture to facilitate machining on the workpiece. The invention includes both specialized molds for use in encapsulating a workpiece for various types of machining and systems for clamping and injecting encapsulant into such molds under pressure. After machining on a given side, a block is re-inserted in the appropriate mold and re-encapsulated to standardize size and shape for a subsequent machining operation. The process of machining and re-encapsulation are repeated until all sides of the workpiece requiring machining have been machined, at which time the encapsulant is removed from the workpiece, normally by being heated and melted.

Wells. Now P.N. 6249562. rmation Appliance activated by a personalization module associated with the user. 6. The device-aware service provisioning method for use in a telecommunications network as set forth in claim 1, wherein the device comprises an Information Appliance activated by a Subscriber Identity Module (SIM) associated with the user. 7. The device-aware service provisioning method for use in a telecommunications network as set forth in claim 1, wherein the device comprises an IP telephony host device. 8. A hybrid telecommunications network having a packet-switched network portion and a circuit-switched network portion, comprising: a plurality of communication devices operable with the hybrid telecommunications network; a service switching node for invoking a device-aware service based on a device-aware service trigger encountered in a call control process; a trigger server containing a user profile which includes a user-specific service policy part, a device-specific service policy service part, and a combination service policy part that is applicable when an end-user uses a particular device of the plurality of communication devices, wherein the service switching node queries the trigger server upon encountering the device-aware service trigger in the call control process; and a service node having means to execute a Service Logic Program based on information obtained from the service switching node. 9. The hybrid telecommunications network as set forth in claim 8, wherein the particular device comprises an IP phone selected from the group consisting of: Session Initiation Protocol (SIP) terminal, H.323 terminal, Internet Appliance, Internet phone, PC phone, laptop phone, smart phone, PDA phone, and Web phone. 10. The hybrid telecommunications network as set forth in claim 8, wherein the particular device comprises a wireline phone. 11. The hybrid telecommunications network as set forth in claim 8, wherein the particular device comprises an Information Appliance activated by one of a personalization module and a Subscriber Identity Module (SIM) associated with the user. 12. The hybrid telecommunications network as set forth in claim 8, wherein the particular device comprises an IP telephony host device. 13. The hybrid telecommunications network as set forth in claim 8, wherein the particular device comprises a mobile phone. 14. A device-aware call diversion method for use in an integrated telecommunications network having a service switching node and a service node, the method comprising the steps of: receiving a call in the service switching node for a user; determining, in the service switching node, if a device-aware service trigger is encountered in a call control process associated with the call; if so, querying by the service switching node a user profile associated with the user to determine if a particular device-specific service part of the user profile is to be invoked, wherein the device-specific service part specifies service conditions applicable to a particular device designated for use by the user with respect to call diversion; responsive to the querying step, instructing the service node, by the service switching node, to execute a Service Logic Program associated with the service conditions specified in the device-specific service part; transmitting, by the service node, a routing number to the service switching node based on the execution of the Service Logic Program; and diverting the call by the service switching node to the routing number obtained from the service node. 15. The device-aware call diversion method for use in an integrated telecommunications network as set forth in claim 14, wherein the device comprises an IP phone selected from the group consisting of: Session Initiation Protocol (SIP) terminal, H.323 terminal, Internet Appliance, Internet phone, PC phone, laptop phone, smart phone, PDA phone, and Web phone. 16.
