20090105439 | Sequentially cross-linked polyethylene - A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen. | 04-23-2009 |

20130303212 | MESSAGING ROUTING - In a message routing method an application or device sends a message in a mobile network, the message having a status report request. The message is delivered via network elements including a router, and the router routs a status report to the originating device or application which cannot accept it. The router communicates with a message service centre having store-and-forward capability, and the message service centre performs a re-try of sending the status report to the originating device or application. The status report may be embedded in an otherwise conventional message to the service centre, which may for example be an SMSC. The status report may be embedded in a conventional SMC-MO PDU, without affecting the GSM or other network protocol. | 11-14-2013 |
20150141003 | METHOD, APPARATUS AND COMPUTER READABLE MEDIUM FOR TERMINATING AND NEWLY CONSTRUCTING A SEND ROUTING INFORMATION (SRI) MESSAGE IN MOBILE NETWORKS - An originating SMSC in Network A issues an SRI-SM towards the HLR of a recipient (User B in Network B). One of a number of N Platforms or Message Controllers (“MCOs”) intercepts the SRI-SM. Instead of passing on the SRI-SM, the MCO terminates it and performs a full decode of all fields, specifically extracting the recipient MSISDN from it. The MCO then constructs a new SRI-SM for the same MSISDN, but forcing the new request to ask for all available data, including, but not necessarily limited to visited-MSC address, SGSN address and IP-SM-GW address. When a response is received the MCO generates a fresh query response for the originating SMSC instead of merely routing on the response which it receives. If the MCO is programmed to provide a false address for smart services it incorporates the false address in the query response which it generates. | 05-21-2015 |
