Publication number: 20240136983Abstract: A scalable periphery tunable matching power amplifier is presented. Varying power levels can be accommodated by selectively activating or deactivating unit cells of which the scalable periphery tunable matching power amplifier is comprised. Tunable matching allows individual unit cells to see a constant output impedance, reducing need for transforming a low impedance up to a system impedance and attendant power loss. The scalable periphery tunable matching power amplifier can also be tuned for different operating conditions such as different frequencies of operation or different modes.Type: ApplicationFiled: October 24, 2023Publication date: April 25, 2024Inventors: Dan William Nobbe, David Halchin, Jeffrey A. Dykstra, Michael P. Gaynor, David Kovac, Kelly Michael Mekechuk, Gary Frederick Kaatz, Chris Olson

Patent number: 11962087Abstract: This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.Type: GrantFiled: February 1, 2023Date of Patent: April 16, 2024Assignee: Aptiv Technologies AGInventors: Scott D.

Residual data for the first sub-region is obtained using the prediction for the first sub-region. A reconstruction of the first sub-region is generated using the residual data for the first sub-region and the prediction for the first sub-region. A prediction for the second sub-region is generated using the reconstruction of the first sub-region. Residual data for the second sub-region is obtained using the prediction for the second sub-region. The input block is encoded based in part on the residual data for the first region and the residual data for the second region.Type: GrantFiled: February 14, 2022Date of Patent: April 16, 2024Assignee: Apple Inc.Inventors: Krishnakanth Rapaka, Alexandros Tourapis, David William Singer
