  • Publication number: 20220396777
    Abstract: In certain example embodiments, the invention provides a method of generating an ex vivo cell-based system comprising dissociating an original tissue sample obtained from a subject into a single cell population; determining an in vivo phenotype of the tissue sample by conducting single-cell RNA analysis on a first portion of the single cells; establishing an ex vivo cell-based system from a second portion of the single cells; and culturing the ex vivo cell-based system in a medium or conditions selected to maintain the in vivo phenotype. In some embodiments, the original tissue sample is a tumor tissue sample, such as a pancreatic ductal adenocarcinoma (PDAC) tumor sample.

  • Patent number: 11434883
    Abstract: A method for operating a variable capacity drive circuit of a compressor includes operating first and second four-quadrant switches in a first state in which the first four-quadrant switch is closed and the second four-quadrant switch is open such that a voltage seen by the motor is equal to an AC line voltage. The method also includes operating the first and second four-quadrant switches in a second state where the first four-quadrant switch is open and the second four-quadrant switch is closed such that the voltage seen by the motor is to zero. Further, the method includes providing a positive firing angle and a negative firing angle for defining when the first and second four-quadrant switches are operated in each of the first and second states. Moreover, the method also includes transitioning between the first and second states using the firing angles at a switching frequency determined by the AC line voltage frequency.

  • Patent number: 11421922
    Abstract: A linear compressor includes a housing defining a sump for collecting a lubricant and a pump for circulating a flow of lubricant within the housing. A heat dissipation or heat exchange assembly includes a plate mounted on a lower portion of the housing to define one or more fluid passageways between the plate and the housing. Hot oil is collected from the working components of the linear compressor and is passed through the one or more fluid passageways to discharge heat through the housing before the oil is returned to the sump.

  • Publication number: 20220154714
    Abstract: A linear compressor or method of operation may provide for driving a motor of the linear compressor to a reference current and detecting a sampled current during driving the motor. The linear compressor or method may also provide for calculating a variance in current using the sampled current, determining the calculated variance exceeds a variance threshold, and restricting the reference current based on determining the calculated variance exceeds the variance threshold.
