  • Publication number: 20230066056
    Abstract: There is provided a method of treating an inflammatory response to infection and complications associated therewith, by administering a proprotein convertase subtilisin kexin 9 (PCSK9) inhibitor to a subject, in need thereof. There is also provided a method of treating or preventing renal failure; renal dysfunction; respiratory failure; respiratory dysfunction; or acute lung injury. Provided herein are uses, pharmaceutical compositions, and commercial packages associated therewith.

  • Publication number: 20080240940
    Abstract: A linear compressor has a hollow piston with crown and sidewall. The piston reciprocates in a cylinder. A piston rod connects the piston to a spring. A connection between the piston rod and the piston transmits axial forces directly to the piston crown. The connection transmits lateral forces to the piston at an axial location away from the piston crown. The connection allows rotational flexibility between the piston and the piston rod transverse to and uniformly around the piston reciprocation axis. Other improvements in or relating to linear compressors are disclosed and claimed.

  • Patent number: 6034493
    Abstract: An electronically commutated brushless DC motor primarily for fractional horsepower applications of the type where at any instant one motor winding is unpowered and used to detect back EMF zero-crossings which information is used to initiate winding commutations. The duration of the pulse produced in this winding due to dissipation of stored energy by free-wheel diodes in parallel with the commutation devices after supply of current has been removed from this winding is used to provide a measure of motor current. This allows for simplified commutation device current limiting circuits and is available for control purposes which are a function of motor torque. There is also disclosed a method for maximizing useful power output by reducing the phase angle between the motor current and the back EMF. This is accomplished by introducing a delay in commutating the motor windings beyond the occurrence of each back EMF zero-crossing, with the delay being a function of the time between commutations.
