Abstract: A sensor probe for monitoring levels of chemical solutions used in automatic car washes, the sensor probes comprising an elongated sensor probe tube able to be installed by being inserted into a hole in the top of storage drums. A sealed enclosure mounted to the top of the tube is thereby positioned above the associated tank, which enclosure contains a liquid level sensor and a wireless receiver/transmitter able to send data to a computer/display/and web server.

Abstract: A magnetic stimulator for stimulation of a tissue by a magnetic field, having a pulse generator device which comprises a pulse capacitor which can be charged by a charging circuit in order to generate a pulse sequence consisting of pulses and having an adjustable repeat rate; and having a programmable control device which adjusts the pulse generator device to generate a complex pulse sequence, which comprises individually configurable pulses, wherein the generated complex pulse sequence is applied to a stimulation coil in order to generate the magnetic field.
