Patent number: 10031003Abstract: A method for manufacturing a system in a wafer for measuring an absolute and a relative pressure includes etching a shallow and a deep cavity in the wafer. A top wafer is applied and the top wafer is thinned for forming a first respectively second membrane over the shallow respectively deep cavity, and for forming in the top wafer first respectively second bondpads at the first respectively second membrane resulting in a first respectively second sensor. Back grinding the wafer results in an opened deep cavity and a still closed shallow cavity. The first bondpads of the first sensor measure an absolute pressure and the second bondpads of the second sensor measure a relative pressure. The etching in the first step defines the edges of the first membrane and of the second membrane in respectively the sensors formed from the shallow and the deep cavity.Type: GrantFiled: December 2, 2015Date of Patent: July 24, 2018Assignees: MELEXIS TECHNOLOGIES NV, X-FAB SEMICONDUCTOR FOUNDRIES AGInventors: Appolonius Jacobus Van Der Wiel, Uwe Schwarz, Rudi De Winter

Patent number: 9398491Abstract: Subscribers are segmented in a telecommunications by allocating given first subscribers network resources with a lower priority than second subscribers, but allowing the first subscribers to temporarily upgrade their subscription by a self-service request. On detecting the request, the network updates the charging correspondingly and adapts the resource allocation of the first subscribers who made the request for a predetermined period and/or amount of phone calls. The network is also capable of signaling the subscribers their current resource allocation priority so that the subscribers can provide respective users with a feedback of changes in resource allocation. The mechanism is also applicable for temporarily lowering the priority of given subscribers in resource allocation.Type: GrantFiled: September 13, 2006Date of Patent: July 19, 2016Assignee: Nokia Technologies OyInventor: Uwe Schwarz

Patent number: 9225847Abstract: A method and corresponding equipment to enable a phone owner, who desires to lend a phone to a borrower, to define a temporary limit for the usage of the borrower, especially in a prepaid charging system. The charging system uses this temporary limit to restrict service usage such that when an amount corresponding to the temporary limit has been spent service is denied until such time as the limit has expired or been withdrawn, even if, for example, there is still a positive balance in the phone owner's own prepaid account.Type: GrantFiled: October 10, 2006Date of Patent: December 29, 2015Assignee: Nokia Technologies OyInventors: Andrew Daymond, Uwe Schwarz, Jens Benner, Ossi Pöllänen, Jan Chipchase

Patent number: 8090376Abstract: A method of selecting a cell for handover of a mobile station to another communication system. A command is sent to a mobile station from a first network element. The command includes a request to perform compressed mode measurements at the mobile station of a neighboring cell. The neighboring cell uses a different communication means than the first network element. Compressed mode measurement results are received from the mobile station at the first network element. The received compressed mode measurement results are weighted with indicators of a prioritized neighbor cell list to form a prioritized list. A second command is sent to the mobile station from the first network element. The second command includes a second request to decode identification codes at the mobile station based on the prioritized list. An indicator of a suitable cell from the prioritized list is received from the mobile station at the first network element.Type: GrantFiled: October 3, 2008Date of Patent: January 3, 2012Assignee: Intellectual Ventures I LLCInventors: Antti Tölli, Uwe Schwarz, Petteri Hakalin, Heikki Hirvonen
