摘要: In order to raise the measuring accuracy of a Coriolis-type mass flow rate meter in a cost-effective fashion, the latter comprises a measuring tube (4), a subcircuit measuring circuit and a subcircuit exciting circuit. Two vibration sensors (17, 18) and a vibration exciting (16) are arranged on the measuring tube. The vibration sensor (17) is assigned the amplifier (v1) in the subcircuit measuring circuit, and the vibration sensor (18) is assigned the amplifier (v2). Downstream of the two amplifiers are the summing stage (ss1) with a downstream integrating stage (ig), and the difference stage (ds). Downstream of the integrating stage (ig), the difference stage and the amplifier (v1) are the A/D converters (aw1, aw2, aw3), following which the digital processor (dp) is connected; it supplies the digital mass signal (m) and/or the digital density signal (d), as well as the gain control signal (v) for the amplifier (v2). The subcircuit exciting circuit contains the digital generator (dg), which supplies the digital exciting signal at the output (a1). The digital frequency controller (fr) is connected on the input side to the digital generator and to the digital processor, and on the output side to the frequency control input of the digital generator. The digital amplitude controller (ar1) is connected on the input side to the output (a5) of the digital processor, and on the output side to the amplitude control input of the digital generator.

摘要: A medical handheld device having a bi-stable display, which can be supplemented by a further display, is presented. The display of the medical handheld device can have a display surface. The display surface can have a keypad in the form of a matrix of sensors. The matrix of sensors can be coupled to image segments on the display surface and can detect touches on the display surface. By coupling the matrix of sensors to the image segments of the display surface, a change of the representation of touched areas of the display surface can occur.
