  • Patent number: 10799662
    Abstract: A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modelled based on the transformed data set.

Alternatively, the actuation apparatus may include a set of coils configured to generate a rotatable magnetic field. The apparatus may further include a magnetic shape memory (MSM) element including MSM material and having a long axis, where the MSM element is configured to contract locally in a first part in response to local exposure to a first component of the magnetic field that is substantially perpendicular to the long axis and to not contract locally in a second part that is exposed to a second component of the magnetic field that is not substantially perpendicular to the long axis. The apparatus may include a first fixed magnet positioned at a first end of the MSM element and a second fixed magnet positioned at a second end of the MSM element.

  • Publication number: 20200297474
    Abstract: The present invention provides an implantable bioreactor comprising cells enclosed within an enclosure, said cells being capable of producing paracrine factors, wherein the enclosure is collapsible or expandable or both or neither, wherein the enclosure is semipermeable such that it provides containment of the cells preventing the egress of the cells while further providing a barrier that shields the cells from immunological attack, and wherein the enclosure is permeable to the entire secretome of the cell including exosomes, nucleic acids and proteins. The implantable bioreactor can have various configurations and can house internally a cell culture matrix than can include hydrogels, microbeads, and nanofiber matrices along with other active agents.

  • Patent number: 10603982
    Abstract: A vehicular climate control system may include a coolant subsystem configured to circulate coolant between an engine, a thermal generator, and a cabin heat exchanger, and a controller. The controller may be configured to, responsive to an air inlet temperature of the heat exchanger exceeding a threshold, retard engine spark timing to increase heat generation. The threshold may be defined by a quotient of (i) a difference between a discharge temperature target and the air inlet temperature and (ii) a thermal effectiveness parameter that is based on an air flow rate and a coolant flow rate.
