  • Patent number: 11965507
    Abstract: A compressor may include a scroll and a discharge valve assembly. The scroll may include an end plate and a spiral wrap extending from the end plate. The end plate may include a discharge passage. The discharge valve assembly may be mounted to the scroll and may be configured to control fluid flow through the discharge passage within the discharge passage. The discharge valve assembly may include a base and a valve member. The base may be fixed relative to the end and may include a discharge opening in communication with the discharge passage. The valve member may be mounted to the base. The valve member may be deflectable relative to the base between a closed position and an open position. The discharge opening may include at least one radially extending lobe.

  • Patent number: 9911889
    Abstract: Certain embodiments of the present invention may be directed to a transistor structure. The transistor structure may include a semiconductor substrate. The semiconductor substrate may include a drift region, a collector region, an emitter region, and a lightly-doped/undoped region. The lightly-doped/undoped region may be lightly-doped and/or undoped. The transistor structure may also include a heterostructure. The heterostructure forms a heterojunction with the lightly-doped/undoped region. The transistor structure may also include a collector terminal. The collector terminal is in contact with the collector region. The transistor structure may also include a gate terminal. The gate terminal is in contact with the heterostructure. The transistor structure may also include an emitter terminal. The emitter terminal is in contact with the lightly-doped/undoped region and the emitter region.

  • Patent number: 9760666
    Abstract: A planned schematic for an electronic system is hierarchically divided into base-level schematic blocks which may be designed individually. In accordance with a plurality of sets of design requirements, variant overlays are designed for each base-level schematic block, each overlay including variant parameter values which may replace corresponding parameter values of the schematic blocks. The schematic blocks are integrated to generate a system-level schematic, and the variant overlays for a given set of design requirements are merged to generate a system variant overlay. Parameter values of the system variant overlay may then replace corresponding parameter values of the system-level schematic to generate a variant schematic for the given set of design requirements.
