Publication number: 20080225816Abstract: An interface, apparatus, and method are described for communication between a radio equipment control (REC) node and a radio equipment (RE) node in a radio base station that tranceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the RE node by a transmission link. Both control information and user information are generated for transmission over the transmission link from one of the REC node and the RE node to the other. Many advantageous interface features are described.Type: ApplicationFiled: September 29, 2004Publication date: September 18, 2008Inventors: Jacob Osterling, Klas Sjerling, Franz Heiser, Armin Splett, Hans Kroner, Peter Merz, Werner Korte, Patrick Lagrange, Eric Georgeaux, Toshifumi Sato, Yang Ganghua, Lan Haioing, Lin Zhibin

Publication number: 20080141759Abstract: The present invention is directed to a method for testing the leakage rate of an encapsulated device comprising the step: bombing the device with a Neon and/or Argon atmosphere using a bombing pressure of at least more than environmental pressure and measuring the quality factor before and after bombing. Preferably, the bombing time is about 10 to 100 hours, and the bombing pressure is 1.5 to 100 bar, more preferably 1.5 to 5 bar and most preferably about 4 bar. With this test, the leakage rate of fine leaks of the device may be determined. This test is helpful in determining statistical surface contaminations or defects caused by wafer processing that affect the seal integrity just enough to cause shorter lifetimes. Further, dicing, die assembly and transfer molding may also introduce physical defects which may be detected with the present method. Finally, the inventive test method may be useful for process optimization: Hermeticity tests are a great help to optimize sealing processes.Type: ApplicationFiled: November 10, 2005Publication date: June 19, 2008Inventors: Wolfgang Reinert, Dirk Kaehler, Peter Merz

Publication number: 20070023137Abstract: Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.Type: ApplicationFiled: October 3, 2006Publication date: February 1, 2007Inventor: Peter Merz

Patent number: 5894071Abstract: Two-component adhesive-, sealing- or coating compositions are being described which are separately packed, and comprise the component A and the component D, whereby the component A is curing as soon as it gets in touch with water or the component D which contains the curing agent for the component A.The component D can be, or a component B containing an ingredient which is curing at the contact of water, or, possibly, at the contact with the component A, orthe component D can also be a mixture of solid matter and a volatile ingredient which is causing the cross-linking of the component A.The advantage of the novel two-component systems is that the component D is working as a curing agent for the component A, however, a surplus thereof is, or self-curing, or it does not leave a nuissance residue in the cured composition.Type: GrantFiled: December 6, 1996Date of Patent: April 13, 1999Assignee: Sika AG, vorm.
