Granted: 1982-06-09
Abstract: A circuit for evaluating signals has an operational amplifier and a comparator, both of which are supplied by a voltage source connected to ground at one side. The reference inputs of the amplifier and comparator are respectively connected to different taps of a voltage divider also connected across the voltage source, the taps being separated by a low-resistance resistor, thus attaining a stable zero signal level at the signal input of the comparator in the quiescent state through the non-inverting input of the operational amplifier and the output thereof, the stable zero signal level exhibiting a constant voltage difference in comparison to the reference potential at the reference input of the comparator.

Title: Arrangement for reducing the transmission of mechanical energy
IPC: G10K11/168
Filed: 1986-07-26
Granted: 1995-06-01
Abstract: To reduce the transmission of mechanical, in particular acoustic, energy between the outer skin of a floating body and the water, a closed-cell plastic foam of low dynamic rigidity, among other things, is applied in a certain coating sequence to the outer skin of the floating body. The plastic foam is covered by an elastic synthetic-resin protective layer with an inlay of glass-fibre fabric as reinforcement.
