Patent ID: 7741603

Claim:
An apparatus comprising: (1) a substrate having a first substrate electrode and a second substrate electrode; (2) a first sensor, wherein said first sensor comprises; (a) a first plate for converting incident radiation into heat, wherein said first plate is physically adapted to conduct electricity and to conduct heat; and (b) a first support arm for supporting said first plate above said first substrate electrode, wherein said first support arm comprises a first actuator for controlling the height at which said first plate is supported above said first substrate electrode; and (3) a second sensor, wherein said second sensor comprises; (a) a second plate for converting incident radiation into heat, wherein said second plate is physically adapted to conduct electricity and to conduct heat; and (b) a second support arm for supporting said second plate above said second substrate electrode, wherein said second support arm comprises a second actuator for controlling the height at which said second plate is supported above said second substrate electrode; wherein at least a portion of said second support arm overlaps at least a portion of said first support arm.
