  • Patent number: 10926353
    Abstract: A method and system is provided for laser piercing of thick plate material that allows for rapid transition to a cutting operation that can reliably produce a piercing hole and complete a cutting operation of the intended shape in a short time, while improving the cutting quality of the cutting after switching from the piercing operation. The cutting nozzle has a centrally located laser. The piercing operation applies a laser beam to the cut work while axially supplied pure oxygen gas is applied towards the cutting work. Additionally, a direction controlled nozzle adjacent the main cutting port provides a discharge of high pressure compressed air non-axially relative to the cutting operation to clear excess molten metal and debris from the kerf thereby increasing the efficiency of the piercing and shortening the cycle time.

  • Patent number: 10881778
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period.
