  • Publication number: 20240308053
    Abstract: A cultivator tool includes a power head having a handle and a user interface. A motor is positioned within the power head and is configured to rotate a drive shaft about a drive axis. The cultivator further includes an attachment stem removably coupled to the power head at a first end and removably supporting a tool attachment unit at an opposite second end. A cover is receivable on the attachment stem between the tool attachment unit and the power head to cover a cutter rotatably supported on the tool attachment unit. The cover includes an aperture configured to receive a projection extending from the stem to limit rotation and sliding of the cover relative the tool attachment unit.

  • Patent number: 12062574
    Abstract: Disclosed is an integrated circuit (IC) structure that includes a through-metal through-substrate interconnect. The interconnect extends essentially vertically through a device level metallic feature on a frontside of a substrate, extends downward from the device level metallic feature into or completely through the substrate (e.g., to contact a backside metallic feature below), and extends upward from the device level metallic feature through interlayer dielectric (ILD) material (e.g., to contact a BEOL metallic feature above). The device level metallic feature can be, for example, a metallic source/drain region of a transistor, such as a high electron mobility transistor (HEMT) or a metal-insulator-semiconductor high electron mobility transistor (MISHEMT), which is formed on the frontside of the substrate. The backside metallic feature can be a grounded metal layer. The BEOL metallic feature can be a metal wire in one of the BEOL metal levels. Also disclosed is an associated method.

  • Patent number: 11994135
    Abstract: Energy efficiency and/or operational stability of a multistage compression system comprising a plurality (N) of centrifugal compressors that is compressing a gas feed having a variable flow rate is improved by adjusting reversibly the load on each compressor in response to changes in the flow rate of the gas feed using a main recycle system to enable operation of the centrifugal compressors at turndown capacity during periods when the flow rate is below total turndown capacity for all of the compressors, and if necessary, using the local recycle systems in order to avoid activation of anti-surge control, and switching one or more centrifugal compressors into low power mode or shutdown mode as required.

  • Patent number: 11916119
    Abstract: Disclosed are embodiments of a transistor (e.g., a III-V high electron mobility transistor (HEMT), a III-V metal-insulator-semiconductor HEMT (MISHEMT), or the like) that has multiple self-aligned terminals. The self-aligned terminals include a self-aligned gate, a self-aligned source terminal and, optionally, a self-aligned drain terminal. By forming self-aligned terminals during processing, the separation distances between the terminals (e.g., between the gate and source terminal and, optionally, between the gate and drain terminal) can be reduced in order to reduce device size and to improve performance (e.g., to reduce on resistance and increase switching speeds). Also disclosed herein are method embodiments for forming such a transistor.

    Abstract: Controlling a capacity of the compression system in response to the variable incoming gas feed by: i) selectively varying a capacity of a first subset of one or more of the compressor trains by continuously varying the capacity of one or more cylinders of the one or more reciprocating compressor stages of the one or more compressor trains of the first subset between a maximum capacity and a minimum capacity; and/or ii) selectively varying a capacity of a second subset of one or more of the compressor trains by fully loading or fully unloading one or more cylinders of the one or more reciprocating compressor stages of the compressor trains of the second subset, wherein the first and second subsets are mutually exclusive.
