  • Publication number: 20210271320
    Abstract: A method for ascertaining a viewing direction of an eye. A laser beam emitted by a laser source is passed over at least two scanning points on the eye, using a reflection element and a deflecting element. A self-mixing effect of the scanning laser beam reflected by the eye into the laser source is used, in order to determine, for the at least two scanning points, the optical path length from the laser source to the at least two scanning points on the surface of the eye and/or a reflectivity of the eye at the at least two scanning points.

  • Patent number: 10957078
    Abstract: A raster unit is configured to generate different sample patterns for adjacent pixels within a given frame. In addition, the raster unit may adjust the sample patterns between frames. The raster unit includes an index unit that selects a sample pattern table for use with a current frame. For a given pixel, the index unit extracts a sample pattern from the selected sample pattern table. The extracted sample pattern is used to generate coverage information for the pixel. The coverage information for all pixels is then used to generate an image. The resultant image may then be filtered to reduce or remove artifacts induced by the changing of sample locations.

  • Patent number: 10910956
    Abstract: A method is provided for operating a frequency converter, which is designed to drive a three-phase motor, wherein the frequency converter has three half-bridges each having at least two switches. The method includes the following steps: generating three phase voltages for the three-phase motor by a pulse width modulation, wherein, for the pulse width modulation, various switching patterns of the switches are activated, wherein specific star point voltages ensue for various groups of switching patterns; and in at least one operating state of the frequency converter, within a respective period of the pulse width modulation, activating only those switching patterns in which an identical star point voltage ensues.

  • Publication number: 20210008106
    Abstract: Methods and compositions relating to isolated mitochondria are disclosed. For example, cells, tissues, or organs can be treated with isolated mitochondria, such as porcine mitochondria, to improve mitochondrial function in the cell, tissue, or organ. The improvements to mitochondrial function include increased oxygen consumption and increased ATP synthesis. Such methods and compositions are useful for cell therapy; organ and tissue transplantation; organ and tissue engineering; and cold storage or shipment of harvested organs, tissues, and cells.

  • Publication number: 20200352157
    Abstract: An automated bioreactor system for decellularizing an organ includes a main chamber for containing the organ. The system further includes a reagent chamber containing a liquid phase reagent. A reagent conduit delivers the liquid phase reagent to the main chamber, and a perfusion conduit delivers the reagent from the reagent outlet in the main chamber into the organ. A perfusion pump drives the flow of the reagent. A perfusion pressure sensor detects a pressure of the flowing reagent. A control system controls the perfusion pump to drive the flow of the reagent based on a received input representative of a desired pressure and a received input of the detected pressure. The control system may automatically perform all of the steps of a decellularization protocol based on sensor input. An automated waste decontamination system may also be provided.

  • Patent number: 10381782
    Abstract: An electrical connector including first and second connector parts configured for mating together, and with one of the connector parts having a sensory feedback member that moves between an extended position and a retracted position as a result of magnetic interaction with an actuation element in the other connector part during mating of the connector parts. The movement of the sensory feedback member causes a sensory feedback indication, such as an audible sound or a tactile vibration.

  • Patent number: 10181735
    Abstract: A portable electrical power unit includes a housing defining an interior region that receives a power source, such as a rechargeable battery or capacitor, and one or more electrical connectors that are accessible at or through outer surfaces of the housing. The housing includes a substantially flat base for resting atop generally horizontal surface, and may include a power switch for selectively energizing the outlets. Optionally, a charging indicator provides a visual indication of the current capacity or charge level of the onboard power source. The power unit may receive or convey electrical power via direct-contact electrical terminals or via inductive power transmission, and may include additional features such as a location-detecting circuit operable to detect and generate a signal in the event that the power unit is moved out of a predefined area.
