Definitions
- the object of the invention is a dually adjustable electromechanical handling means and a handling means system,, and dually adjustable digital potentiometer, to be used as a control or potentiometer for electrical equipment, especially audio equipment.
- dually adjustable electromechanical handling means and a handling means system to be used as a control or potentiometer for electrical equipment, especially audio equipment.
- dual adjustment and “dual control” we mean the possibility of controlling and adjusting both manually and in an electronic way.
- the electromechanical handling means according to the invention has a controlled circuit.
- handling means refers to a control device having a movable element, which movable element has an initial status before its displacement and a final status after its displacement, and the value of a certain electric parameter corresponding to the initial status and the value of the electric parameter corresponding to the final status are different.
- the best known electromechanical handling means making it possible to adjust an electric parameter is the potentiometer.
- the slider of the potentiometer depending on its design, can be manually set into the desired position via shifting or turning it, resulting in variable resistance or variable division ratio.
- the disadvantage of it is that as the adjustment of the potentiometer is done manually, it is not possible to set several potentiometers simultaneously due to the time required, or it can only be solved with time delay. Further, if the potentiometer must be adjusted while e.g. playing an instrument., it can only be done with difficulties as either there will be unwanted break in the play, or the potentiometer will be set not in the desired instant.
- the integrated circuits DS 1668 and 1669 (manufactured by Dallas Semiconductor)., which are controllable digital potentiometer circuits.
- the circuit has a control circuit and a network of resistors forming a potentiometer with the three potentiometer poles, where the resistance between the two outer poles is fix, the middle pole forms a slider output, and the position of the slider at any time is determined by the slider control circuit connected to the output of the control circuit.
- the division of the potentiometer or, if it is used as a variable resistor, the resistance can be adjusted in quanta.
- the resistance can be adjusted or set by a digital series of signals applied on the appropriate control input of the circuit, or by applying voltage signals by a push button on the other, upward or downward stepping input of the circuit.
- the fundamental idea of the invention is that setting a large number of handling means or potentiometers of an equipment to another status which is significantly different from the original status can only be realised quickly and reliably if the individual handling means are fashioned in a way that besides being suitable for being adjusted both manually and by digital signals, manual adjustment can be realised with a single movement of given direction and the required magnitude, and the time taken by this movement plays no role in the result of the manual adjustment.

- a preferable realisation of this embodiment has an input suitable for receiving MIDI signals, and the output suitable for emitting signals of MIDI standard is connected either to the output of the MIDI signal generator or to the input suitable for receiving MIDI signals, depending on the controlled status of the microcomputer.
- a further solution for the.problem according to the invention is a dually adjustable digital potentiometer, having electronically switchable resistor network and displacement transducer of which form an integrated electromechanical device, having an interface setting the division ratio at the resistor network corresponding to the digital code received at its input - from a controller -, having a display indicating the division ratio, and the displacement transducer has a port sending signal . proportional with displacement - to be forwarded to a controller -.
