Patent ID: 8159681

Claim:
A measuring device for determining a relative offset between two components in a z-direction, comprising: a first measurement member affixable on a first component at a rigid angle and to transmit movements of the first component, having a directional component parallel to the z-direction, from the first component to the first measurement member; a second measurement member affixable on a second component at a rigid angle and to transmit movements of the second component, having a directional component parallel to the z-direction, from the second component to the second measurement member; a sensor device adapted to determine a relative position of the measurement members; and support members for at least one measurement member, the at least one measurement member configured to assume a parking position and an operation position; wherein at least one of: (a) the first measurement member is configured to adhesively and releasably contact the first component; and (b) the second measurement member is configured to adhesively and releasably contact the second component; and wherein, in the parking position, the measurement members are reproducibly aligned in space with respect to each other in accordance with the configuration of the support members; wherein, in the parking position, at least one of: (a) the first measurement member is unaffixed to the first component; and (b) the second measurement member is unaffixed to the second component; and wherein, in the operation position, the first measurement member is immovably affixed to the first component and the second measurement member is immovably affixed to the second component.
