  • Patent number: 11378225
    Abstract: Display assemblies for supporting displays on stands or support arms have mount portions to removably attach to the displays using magnetic assemblies and latches. The magnetic assemblies and latches can improve user experience and allow the display to be installed on a support arm from the viewing side of the display and without having to see or reach behind the display. Magnetic structures can center a mount portion of the support arm and a recess of the display and can attract them to each other. Laterally-extending latches can ensure the display is not inadvertently removed. Locking mechanisms can prevent the display from being rotated to a portrait orientation when sufficient space around the display and the necessary user intent is not provided.

  • Patent number: 11295953
    Abstract: An apparatus for micromachining a semiconductor material from opposing sides through synchronous coordination of laser and electrochemistry includes an optical path system, a stable low-pressure jet generation system, and an electrolytic machining system. The optical path system includes a laser generator, a beam expander, a reflector, a galvanometer, and a lens. The electrolytic machining system includes a direct-current pulsed power supply, an adjustable cathode fixture, an electrolyte tank, a current probe, and an oscilloscope. The stable low-pressure jet generation system provides an electrolyte flow into a metal needle. The electrolyte flow forms an electrolyte layer between a semiconductor material and a cathode copper plate, such that the cathode and the anode are in electrical contact with each other. In a method employing the apparatus, a laser beam is irradiated onto the semiconductor material to form a local high-temperature region, which leads to a localized increase in electrical conductivity.

  • Publication number: 20220099470
    Abstract: Disclosed is a method for determining a flowed amount of a medium using a first flow measuring transducer according to a first measuring principle and a second flow measuring transducer according to a second measuring principle. The measured values of the first transducer are more reliable in first states of the medium than measured values of the second transducer, and the second measured values are more reliable in second states than the first measured values. A contribution to the flowed amount is ascertained based on the more reliable measured values. The contribution to the flowed amount based on the second measured values is ascertained by means of a transfer function. An updated version of the transfer function is ascertained when the first measured values are more reliable, and the flowed amount earlier ascertained based on the second measured values is corrected as a function of the updated transfer function.
