Patent number: 11929317Abstract: New types, structures, and arrangements of capacitor networks for harmonic control and other purposes are presented. In one example, an integrated device includes a capacitor network and one or more power devices. The capacitor network includes a bond pad and metal-insulator-metal (MIM) capacitors. The capacitors include a first metal layer, a second metal layer, an insulator layer between the first and second metal layers, and one or more through-substrate vias. The first metal layer is coupled to the bond pad, and the second metal layer is coupled to a ground plane on a bottom side of the substrate by the vias. A number of capacitors can be arranged around the bond pad in the capacitor network for a tailored capacitance. A matching network in the integrated device can incorporate the capacitor network to reduce loss, provide better harmonic termination, and achieve better phase alignment for the power devices.Type: GrantFiled: December 7, 2020Date of Patent: March 12, 2024Assignee: MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.Inventor: Prity Kirit Patel

Patent number: 8161589Abstract: An adjustable ramp apparatus installed as part of a flat surface, such as a deck, adapted for angular elevation to an inclined position for providing a ramp between the platform level and the entryway door sill level of a trailer-type home. The apparatus is elevated by means of an actuator-driven mechanical linkage located under the surface of the primary ramp platform adjacent to the trailer type home or structure. When the actuator is disengaged, the ramp returns to a lowered position so that the door to the home is not blocked. An alternative embodiment includes a secondary threshold ramp located beneath the surface of the primary ramp platform that moves into place as the apparatus is actuated to fill the gap between the door sill and the elevated primary ramp platform.Type: GrantFiled: February 15, 2011Date of Patent: April 24, 2012Inventors: Robert B.

Patent number: 7937698Abstract: The illustrative embodiments provide a computer implemented method, apparatus, and computer usable program code for automatically migrating a resource adapter component. In one embodiment, information describing a development and runtime environment associated with a first version of a resource adapter is collected by a migration framework to form real environment information. A specification of requirements associated with a second version of the resource adapter is received from the second version of the resource adapter to form a required environment specification. The migration framework compares the real environment information with the required environment specification. In response to identifying incompatibilities between the real environment information and the required environment specification, the migration framework automatically executes a migration scenario to resolve the incompatibilities.Type: GrantFiled: August 2, 2007Date of Patent: May 3, 2011Assignee: International Business Machines CorporationInventors: Ella Belisario, Jason Nathaniel Lacombe, Adriana M.
