Patent number: 8129834Abstract: A plurality of FPGA dice is disposed upon a semiconductor substrate. In order to supply the immense power required by the plurality of FPGA dice, power is routed through the semiconductor substrate vertically from thick metal layers and large integral metal structures located on the other side of the semiconductor substrate.

In this way the switching unit can be arranged on the GND port of the HF-element, without influencing the HF characteristics of said HF element.Type: GrantFiled: March 6, 2008Date of Patent: March 6, 2012Assignee: Vega Grieshaber KGInventor: Christoph Mueller

Patent number: 8129867Abstract: A system and method for overcoming the parasitic elements associated with off the shelf or general purpose solid-state devices configured to operate as RF AC/DC signal coupling networks. An AC/DC signal coupling network may comprise a general purpose solid-state relay device and two inductors having values carefully chosen to compensate for the imperfections and intrinsic parasitic elements associated with the solid-state relay. The inductors may also have values carefully chosen to compensate for the parasitic elements of the neighboring or coupled circuit, and for the capacitance that is associated with the printed circuit board bond pad that is directly dependent upon the area of the pad and distance to the neighboring conductors. The inductors may cause the input path to become inductive as the signal frequency increases, and also improve the input return loss over the RF input range.Type: GrantFiled: March 24, 2009Date of Patent: March 6, 2012Assignee: National Instruments CorporationInventors: Zaher G. Harb, Mark Whittington

Patent number: 8129870Abstract: An asymmetric folded spring flexure suspension system can enable an ultra-compact linear reciprocative device wherein a reciprocative mass suspended from a base by a single folded flexure assembly extends in a single generally radial direction perpendicular to the intended travel path. The folded flexure assembly can be configured as three side-by-side stacks of flexure strips of spring material, tied together at a “yoke-idler” end; at the opposite “working” end, a central stack of nominal width is tied to the mass, and, flanking the central stack, a pair of half-width stacks are tied to opposite sides of the base. In an embodiment for active vibration control, a cylindrical enclosure, of magnetically-permeable material and attached to the working end of the flexure assembly, contains a driver system including an internally-mounted pair of permanent magnets that provide a magnetic flux gap and also constitute the main portion of the mass.Type: GrantFiled: August 4, 2009Date of Patent: March 6, 2012Inventor: Kenneth E. Pusl

Patent number: 8129872Abstract: An impeller and at least a portion of a cooperating peripheral volute may be integrated are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless D.C. motor with low length to diameter ratio and suitable for use in a variety of other applications. A rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a rotor magnet having a number of poles of alternating polarity and separated by a relatively small cylindrical air gap from a fixed stator assembly. The fixed stator assembly is integrally molded into a base housing having a bearing support that extends upwardly through the center of the stator assembly and that is rotatably coupled to a rotating shaft that extends downwardly from the center of the rotating cap.Type: GrantFiled: September 27, 2010Date of Patent: March 6, 2012Assignee: Resmed Motor Technologies Inc.Inventors: Leslie C. Hoffman, Barton J. Kenyon, David B. Sears
