Abstract: A phase-shifter for a light-transmitting waveguide is segmented into multiple segments that can be calibrated to the overall length of a conventional single phase-shifter. Each segment receives a control signal, which can be a single bit signal, with the phase-shift capability of the segmented phase-shifter controlled by which segment(s) receive(s) a control signal. In one implementation, a binary weighting is applied to determine segment lengths. Smaller segments can be increased in length to achieve a 2? offset of the phase shift produced by the segment while maintaining the same binary relationship among segments. In another embodiment, multiple segments of uniform lengths can be used for a single phase-shifter with each segment controlled by an n-bit signal.

Abstract: A verification of a pipette results in a release or a warning message. A liquid measuring container (110) receives the pipette liquid volume (VP) to be verified. A loading cell (120) is connected to the liquid measuring container in a force-transmitting manner. The loading cell outputs a measurement signal (ms) corresponding to the weight force (FG) acting thereon. A processing unit (130) detects and processes the measurement signal (ms), determines a first weight force (Gt1) at time point (t1) and determines a second weight force (Gt2) at time point (t2). The pipette liquid volume is calculated and the calculated value is assigned to a pipette volume class (Ki) having a defined class nominal value (VKi). The processing unit tests whether or not an absolute value of the volume difference (?V) is within a predetermined tolerance value (T) for the assigned pipette volume class. The processing unit outputs the test result.
