  • Patent number: 10074963
    Abstract: A tangent suspension bracket configured for coupling to at least one of a suspension insulator and a conductor clamp assembly. The tangent suspension bracket further includes a central cap, a first end attachment structure and a second end attachment structure. The central cap structure includes an upper wall having an opening and a depending skirt, together defining a downwardly opening cavity. The opening is structurally configured to allow the passage of a portion of one of the suspension insulator and the conductor clamp assembly while maintaining a portion within the downwardly opening cavity, so as to secure the central cap structure to one of the suspension insulator and the conductor clamp assembly. The first end attachment assembly extends from the central cap and the second end attachment structure extends from the central cap in the opposite direction.

  • Patent number: 10037911
    Abstract: Assemblies including a device layer of a silicon-on-insulator (SOI) substrate and a replacement substrate replacing a handle wafer of the SOI substrate, and methods for transferring the device layer of the SOI substrate from the handle wafer to the replacement substrate. A device structure is formed in a first section of the handle wafer, and a second section of the handle wafer adjoining the first section of the handle wafer is removed to expose a surface of the buried dielectric layer of the silicon-on-insulator substrate. A permanent substrate is attached to the surface of the buried dielectric layer. When the permanent substrate is attached to the surface of the buried dielectric layer, the section of the handle wafer is received inside a cavity defined in the permanent substrate.

  • Patent number: 9916415
    Abstract: Disclosed are embodiments for modeling integrated circuit (IC) performance. In these embodiments, a parasitic extraction process is performed to generate a netlist that, not only accounts for various parasitics within the IC, but also accounts for substrate-generated signal distortions (e.g., substrate-generated harmonic signal distortions) that occur within the IC. During this netlist extraction process, the design layout of the IC is analyzed to identify parasitics that are to be represented in the netlist and to also identify any circuit elements with output signals that are subject to substrate-generated signal distortions. When such circuit elements are identified, signal distortion models, which were previously empirically determined and stored in a model library, which correspond to the identified circuit elements, and which account for the signal distortions, are selected from the model library and incorporated into the netlist.

  • Patent number: 9899785
    Abstract: An electrical transmission line repair device including a first conductor clamp, a second conductor clamp and at least one tie rail extending between the first and second conductor clamps in a spaced apart orientation. The first conductor clamp including a lower assembly and an upper assembly. The lower assembly and the upper assembly are slidably engageable with each other so as to define a conductor cavity extending therealong. Clamping fasteners are configured to extend through openings in the upper assembly so as to be threadable toward and away from the conductor contact region of the lower assembly within the conductor cavity.
