Patent ID: 7648120

Claim:
A arrangement for causing substantially linear displacement of an element of interest, the arrangement comprising: a first carrier element; a second carrier element; a first compliant beam element coupled at a first end thereof to the element of interest and at a second end thereof to said first carrier element; and a second compliant beam element coupled at a first end thereof to the element of interest and at a second end thereof to said second carrier element; whereby motion of said first carrier element relative to said second carrier element results in the substantially linear displacement of the element of interest wherein said first and second carrier elements comprise respective first and second ring carrier elements, said first and second ring carrier elements being arranged in coaxial relation with respect to each other; wherein there is further provided a second element of interest, and there are additionally provided: a further first compliant beam element coupled at a first end thereof to the second element of interest and at a second end thereof to said first carrier element; and a further second compliant beam element coupled at a first end thereof to the second element of interest and at a second end thereof to said second carrier element; whereby motion of said first carrier element relative to said second carrier element results in the substantially linear displacement of the second element of interest.
