  • Patent number: 11918485
    Abstract: Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.

  • Patent number: 11211619
    Abstract: Presented are fuel cell systems and control logic for extracting water from system exhaust, methods for making/using such systems, and electric-drive vehicles with aftertreatment systems for extracting water from fuel cell exhaust. An aftertreatment system for a fuel cell stack includes a condensate generator that fluidly connects to the fuel cell stack to receive exhaust output therefrom. The condensate generator includes an evaporator core with a refrigerant line that actively cool the exhaust via controlled circulation of refrigerant fluid. A condensate collector fluidly connected to the condensate generator includes a reservoir housing with a condensate trap that separates entrained water vapor from the cooled exhaust. The reservoir housing collects the separated water vapor as liquid water. A liquid storage container fluidly connected to the condensate collector receives and stores the collected water.

  • Patent number: 10473370
    Abstract: An automobile vehicle refrigeration system combined ejector-receiver includes a container. An internal heat exchanger (IHX) is positioned entirely within the container. The IHX includes a canister. A receiver and dryer is located entirely within the container and is positioned at least partially within the canister defining a cavity between the receiver and dryer and the canister to receive a refrigerant. An ejector is positioned within the container. An ejector feed line is in communication with the cavity between the receiver and dryer and the canister, the ejector feed line receiving the refrigerant after discharge from the cavity for flow into the ejector. A refrigerant phase separator is positioned within the container. The refrigerant phase separator receives the refrigerant after discharge from the ejector for separation into each of a refrigerant gas and a refrigerant liquid.
