  • Patent number: 11073436
    Abstract: A sensor device including a deflectable membrane made of a 2D nanomaterial, a first optical waveguide for guiding light, disposed adjacent to the membrane and extending along the surface of the membrane at least in a first section, as well as a measuring device for measuring, within the first section the influence of the membrane on an evanescent wave range of the light guided along the first optical waveguide. The influence of the membrane on the light guided in the optical waveguide, in particular on the evanescent wave range of the light, can be measured interferometrically by detecting phasing differences or phase shifts. This allows for a force-free readout of the membrane deflection. By using very thin 2D nanomaterials, the membrane can also react to very quick changes in force.

  • Publication number: 20070006611
    Abstract: A Thermostatic Flow Controller composed of two capillary tubes and a tube form receiver, placed in thermal contact with the suction line. It makes a robust, hermitic closed device, without any moveable parts, no need for adjustment or service and therefor suited for inaccessible placement—for instance encapsulated in isolation foam. The flow of refrigerant to the evaporator is controlled by the pressure in the receiver—and the pressure in the receiver is controlled by the need for refrigerant in the evaporator. This balance ensures that the evaporator is flooded, and thereby exploited 100%—for all kind of charges. The invention is suited for small household freezers and refrigerators. For a small extra cost, it replaces the traditional capillary tube, and makes these devices working optimal on both cold and warm locations, and makes the manufacturing more easy because the amount of refrigerant is no longer critical as it is for traditional capillary tubes.
