Abstract: Exemplary liquid lenses generally include two liquids disposed within a microfluidic cavity disposed between a first window and a second window. Applying varying electric fields to these liquid lenses can vary the wettability of one of the liquids with respect to this microfluidic cavity, thereby varying the shape and/or the curvature of the meniscuses formed between the two liquids and, thus, changing the optical focal length or the optical power of the liquid lenses. These liquids can expand and/or contract as result of varying temperatures. The exemplary liquid lenses include one or more thermal compensation chambers to allow these liquids to expand and/or contract without impacting the integrity of the microfluidic cavity, for example, without bowing or deflecting the first window and/or the second window.

Abstract: A liquid lens apparatus includes a first substrate and a sensor. The first substrate has first and second opposing surfaces, a central portion, and a peripheral portion outside of the central portion. The sensor is formed lithographically on either the first or second surfaces of the peripheral portion of the first substrate such that the sensor is on an exterior surface of the liquid lens apparatus. The sensor is configured to detect a temperature of the liquid lens apparatus to enable compensation for thermal expansion or contraction of the liquid lens apparatus resulting from changes in temperature of the liquid lens apparatus.

Abstract: A valve may be utilized in a high-performance chromatography system for separating components of a sample liquid introduced into a mobile phase. The valve has a first valve element and a second valve element. By a movement of one valve element relative to the other, a first effective surface of the first valve element is brought into connection with a second effective surface of the second valve element, and a flow path may be produced or suppressed. The second valve element has an elastic region to compensate for an axial angle between the first valve element and the second valve element, such that the first effective surface and the second effective surface may be oriented parallel to each other. This may favorably influence a fluidic leak tightness and/or longevity of the valve.

Abstract: An aircraft has a first antenna arrangement, a payload and a processing unit. The first antenna arrangement is designed to wirelessly receive electromagnetic signals. The processing unit is coupled to the first antenna arrangement, on the one hand, and to the payload, on the other hand. The processing unit is designed to modulate an electromagnetic signal received by the first antenna arrangement and thereby to generate a first modulated signal and to forward it to the payload. The payload is designed to use the first modulated signal as working signal. A radiofrequency power signal on an uplink is thus remodulated into a payload working signal, such that the payload working signal is able to be used directly by the payload without rectification into a DC voltage.
