Title: Method of routing calls to portable numbers in a radio telecommunications network
Inventor: BRITT MARGARET
IPC: H04W8/28
Filed: 1998-10-02
Granted: 2012-09-18
Abstract: A method of routing a call directed to a portable directory number in a radio telecommunications network having an originating mobile switching center (O-MSC), a home location register (HLR), and a Number Portability Database (NPDB). The O-MSC determines whether to send a Location Request (LOCREQ) message to the HLR for a routing number, or to send a Number Portability Request (NPREQ) message to the NPDB for a location routing number (LRN).  The determination may be based on operator preference, a default preference, or statistics indicating that either the HLR or the NPDB is more likely to return a routing number. The O-MSC then attempts to obtain a routing number from the determined destination. If an error message is returned, the O-MSC attempts to obtain a routing number from the alternate destination. Upon receipt of a routing number, the O-MSC routes the call. In an alternative embodiment, the O-MSC may send the LOCREQ message and the NPREQ message simultaneously, and utilize the first routing number received to route the call.

Granted: 2007-07-10
Abstract: Conventionally, the last some digits of the Animal Registration Number printed on ear tag for identifying an individual animal in a wide area like a nation are simply enlarged for farm use. However, the simply enlarged farm use number is not a desirable number for the farm to use and is inconvenient for the farm to control animals on the farm. The present invention provides the improvement of making the ear tag, containing an Animal Registration Number CN controlled by the specific management department consisting of codes including numerals, letters, or barcodes, to be used by attaching it to an ear of an animal, in order to identify an individual animal. The Animal Registration Number CN having multiple digits prepared at the specific management department is printed at least on one of the sides of the ear tag. Some part of the Animal Registration Number CN is enlarged and printed on the ear tag as a farm use number FN in accordance with a request from an individual farm by using a minimum number of digits. The enlarged farm use number FN is generated by selecting some digits from the Animal Registration Number CN and is printed on the same or a different side of the ear tag where the Animal Registration Number is printed, so that the farm use number can be effectively created from the Animal Registration Number CN.

Inventor: BOUCHER RONALD
IPC: F01C1/46
Filed: 2001-02-12
Granted: 2004-04-27
Abstract: This invention comprises a rotary vane engine that can be used in any application in which a piston driven engine is currently being used. Most currently available engines are complicated and have many moving parts dependent upon one another.   The transference of energy from the combustion chamber to the drive shaft is usually not a direct one and often energy is lost.      The Boucher Rotary Vane Engine has very few moving parts and energy is transferred directly from the combustion chamber to the drive shaft resulting in very little energy loss. This means less fuel is used and more useable energy is available. The simplicity and uniqueness of its design is due mainly to the placement of eccentric rotors and 2 vanes. The engine is made up of 2 halves, a compression half and an expansion half, with similar structure and sharing a single output shaft.

Title: Torsional responsive ski
Inventor: HEUVEL JOHAN G F
IPC: A63C9/08
Filed: 2001-04-20
Granted: 2007-12-11
Abstract: The invention relates to a ski wherein a binding portion transfers torsional and vertical forces from a binding via a torsional responsive element to forward and rearward ski portions and vice versa, urging a controlled twist onto a ski. In a prior art ski, a torsional response of the forward ski portion, relative to the binding is substantially independent of the torsional response of a rearward ski portion, relative to the binding and vice versa. In the ski according to this invention, a torsional responsive element coordinates and transmits vertical and torsional forces from the binding to the forward and rearward ski portions. The torsional response to edging related longitudinal weight shift facilitates the execution of low speed turns (1), provides foot swivel torsional control,(2), and provides ski flexing related advantages associated with longitudinal load distributing structures.(3)

Title: Protein for blocking platelet adhesion
Inventor: STRITTMATTER WOLFGANG
IPC: A61K38/46
Filed: 2000-03-10
Granted: 2010-09-21
Abstract: A naturally occurring protein isolated from the saliva of the medicinal leech Hirudo medicinalis is described which strongly binds to collagen thus acting as an inhibitor of natural platelet adhesion to collagen. The protein has a molecular weight of about 12 000, an acidic isoelectric point and contains six cysteins. The protein was sequenced and the gene was cloned from a H. medicinalis cDNA-library. Procedures for producing such polypeptide by recombinant techniques are disclosed. The recombinant and the natural occurring proteins are potent inhibitors of collagen-dependent platelet adhesion and therefore useful for the therapeutic treatment of various conditions related to hard disease and diseases of the circulation system. Furthermore the protein is useful for coating natural or artificial collagen surfaces in order to render them nonadhesive for cells and prevent the activation of cells.
