Linked micromechanical positioning apparatus for real-time testing and measurement

A method, system and apparatus for determining the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state. A signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state.

Method and a device for measuring muscle signals

In order to determine the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state, a signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state. A mapping is used to improve accuracy of state determination, e.g. with a reference database.

Method and device for measuring muscle signals

The aspects of the disclosed embodiments relate to a micromanipulator arrangement that includes at least one drive stem, at least one movable element arranged on the drive stem to move along the drive stem wherein the drive stem being arranged to cause a change in a position of the movable element with respect to the drive stem; wherein an additional factor exists having an effect in the change of the position of the movable element and the micromanipulator arrangement further comprises means for compensating said additional factor such that said effect is diminished.

Micromanipulator arrangement

A compact micromanipulator system has a micromanipulator element that cause movement of a tool attached to the micromanipulator element. The micromanipulator element is attached to a support structure, which in turn is attached to a sliding base in a hinged manner to allow sliding and/or tipping of the micromanipulator element away from the normal operating position of the micromanipulator element.
