Publication number: 20180315693Abstract: In various embodiments, a flip-chip device is provided. The flip-chip device includes a chip having an electrically conductive chip contact, and a carrier having an electrically conductive contact area for contacting the chip contact. The chip contact includes a material which is at least just as easily deformable as a material of the electrically conductive contact area at least during the contacting of the chip contact. The contact area includes a plurality of depressions. A smallest width of each of the depressions is smaller than a smallest width of the chip contact. Each of the distances between adjacent edges of adjacent depressions is smaller than the smallest width of the chip contact. The plurality of depressions in the contact area are formed as tubular depressions. A ratio of diameter to depth of the tubular depressions is in a range of 1:3 to 1:50.Type: ApplicationFiled: April 26, 2018Publication date: November 1, 2018Inventors: Benedikt KINDL, Andreas BEER, Uwe WAGNER, Philip SEEBAUER, Christian KIESL

Patent number: 7193414Abstract: An expert system is included in a downhole processor designed to acquire and process NMR data downhole in real time. The downhole processor controls the acquisition of the NMR data based at least in part on instructions transmitted downhole from a surface location and at least in part on evaluation of downhole conditions by the expert system. The downhole conditions include drilling operation conditions (including motion sensors) as well as lithology and fluid content of the formation obtained from other MWD data. The wait time, number of echos, number of repetitions of an echo sequence, interecho time, bandwidth and shape of the tipping and refocusing pulses may be dynamically changed. Data processing is a combination of standard evaluation techniques. Selected data and diagnostics are transmitted uphole. The expert system may be implemented as a two stage neural net. The first stage does the formation evaluation and the second stage controls the NMR pulse sequence.Type: GrantFiled: April 21, 2004Date of Patent: March 20, 2007Assignee: Baker Hughes IncorporatedInventors: Thomas Kruspe, Christian Kiesl, Holger Thern, Hartmut Schrader

Patent number: 6977499Abstract: An apparatus and method for determining a parameter of interest of a formation composed of carbonate rock. A nuclear magnetic resonance (NMR) sensor assembly produces a pulsed RF field designed for obtaining measurements indicative of the parameter of interest of the formation. A downhole processor processes the measurements for obtaining BVI and BVM using a cutoff time based on classification of the carbonate. Further processing is done to estimate the permeability of the carbonate.Type: GrantFiled: May 21, 2003Date of Patent: December 20, 2005Assignee: Baker Hughes IncorporatedInventors: Christian Kiesl, Thomas Kruspe, Holger F. Thern, Iris Surholt
