Patent DE-19805413-A1 (DE)
Inventor: LUDWIG REINHOLD
IPC: G02F1/035
Filed: 1998-02-11
Abstract: The invention relates to a device for switching and scanning clocked optical data signals, especially digital optical data signals in a time multiplex schema. According to the invention, an optical switching device (10, 20, 21) is provided which comprises an amplification profile adapted to the spectral range of control signals.

In this manner, the data signals can be controlled with spectral proportional control signals which are remotely distanced from one another, for example, for carrying out time multiplex, time demultiplex or scanning operations in such a way that the data signals are not disturbed by the control pulses or by the optical components of the switching device which interact with said control pulses.
Patent DE-19809662-A1 (DE)
Title: Sensor for analyzing fluid media such as gas mixtures, e.g. aerosol or dust
IPC: G01N29/032
Filed: 1998-03-06
Abstract: An acoustic sensor detects the sound absorption occurring when a standing acoustic wave is present in a fluid medium (4) to be analyzed. A channel (3) is filled with the medium, and a sound source directed into the channel. The signals from a receiver (2) are fed to a processing unit (6), and measurement values are determined for the amplitudes of the signals. The ends of the channel may be acoustically hard or acoustically soft. The length, L, of the channel is larger than its equivalent diameter, and at least 1.7 times as large as the diameter. At least one end of the channel may be completely or almost completely open, i.e. acoustically soft, or may be completely or almost completely closed, i.e. acoustically hard. The sound transmitter has at least one resonance frequency, fR, and produces a sound signal of this frequency. If one end of the channel is acoustically soft, and the other end is acoustically hard, the resonance frequency satisfies the equation fR = (2n+1)CM/4L, where n is a positive integer and CM is the speed of sound in the medium. If both ends of the channel are acoustically soft, then the resonance frequency satisfies the equation fR = (n+1)CM/4L. If both ends of the channel are acoustically hard, then the resonance frequency satisfies the equation fR = (n+1)CM/2L. The sound transmitter and the sound receiver are connected together with insulation against structure-borne noise.
