  • Publication number: 20240106493
    Abstract: A cognitive radio device may include a radio frequency (RF) detector, an RF transmitter having a selectable hopping frequency window, and a controller. The controller may be configured to cooperate with the RF detector and RF transmitter to detect a jammer signal, determine a jammer type associated with the jammer signal from among a plurality of different jammer types based upon a game theoretic model, and operate the RF transmitter to change the selectable hopping frequency window responsive to the determined jammer type of the jammer signal.

  • Publication number: 20230041227
    Abstract: An electrical assembly that with an inverter that is mounted to the field windings of a stator. The inverter has a plurality of power semiconductor packages (PSP), each of which including a semiconductor die, a plurality of electric terminals, which are electrically coupled to the semiconductor die, and a heat sink with a base, which is fixedly and electrically coupled to one of the electric terminals, and a plurality of fins that extend axially from the base in a direction away from the semiconductor die. The PSP's are arranged in a circumferentially spaced apart manner. The fins are arranged in rows and are progressively longer in length from a radially-inner most fin to a radially-outer most fin. Slots are formed in the base on a radially-inner side of the base. Each slot extends toward a radially-outer side of the base and intersects a corresponding one of the rows of fins.

  • Publication number: 20220372890
    Abstract: In the compressor of a gas turbine engine, variable guide vanes are adjusted by virtue of connections to an actuation ring that can be rotated within a fixed range of degrees. The connections between the guide vanes and the actuation ring can undergo significant torsional stress. Accordingly, an actuation system is disclosed for reducing the torsional stress experienced by the actuation connections.

  • Publication number: 20220037241
    Abstract: An electrical assembly that includes a semiconductor die, a heat sink and a case. The semiconductor die includes a power semiconductor device with a plurality of terminals, and a plurality of electrically conductive leads. Each of the electrically conductive leads is electrically coupled to an associated one of the terminals on the power semiconductor device. The heat sink has a base, a mount, and a plurality of fins. The mount extends from a first side of the base and is coupled to the semiconductor die. The fins are fixedly coupled to the base and extend from a second side of the base that is opposite the first side of the base. The case is formed of a first electrically insulating material. A first one of the leads is integrally and unitarily formed with the mount.

  • Patent number: 11236615
    Abstract: A stator assembly, at a compressor mid-plane in a gas turbine engine, to be mounted around a rotor disc, enables access to the rotor disc (e.g., for trim balancing), without requiring disassembly of the stator assembly and/or a compressor case in which the stator assembly is housed, via a removable stator vane. The stator assembly may comprise vane apertures, aligned along a radial axis, that hold the removable stator vane when inserted into the stator assembly, and provide a radial pathway to the rotor disc, when the removable stator vane is removed from the stator assembly. In addition, a case access assembly may seal the removable stator vane in place within a compressor case when engaged, and provide access to the removable stator vane and radial pathway through the compressor case when disengaged. This enables trim balancing of a mid-plane compressor rotor assembly through the stator assembly and compressor case.
