  • Patent number: 10254306
    Abstract: A method of performing a measurement routine on a probe, the probe comprising a cantilever extending from a support. An interferometer is operated to reflect a sensing beam with the cantilever thereby generating a reflected sensing beam and combine the reflected sensing beam with a reference beam to generate an interferogram. The interferometer generates a first interference measurement value at a first measurement time by measuring the interferogram and a second interference measurement value at a second measurement time by measuring the interferogram, The cantilever deforms to form a different shape between the measurement times. A change in height of the probe between the measurement times is estimated in accordance with a difference between the first and second interference measurement values, and corrected in accordance with the difference in shape of the cantilever between the measurement times.

  • Patent number: 7394210
    Abstract: The present invention provides a programmable lighting system comprising a plurality of light-emitting elements and a controller responsive to a hierarchically encoded data input stream. The controller determines and provides appropriate control signals for controlling the characteristics of the light generated by the plurality of light-emitting elements operatively coupled thereto. The data input stream may use a DMX512 or other network protocol and can be hierarchically encoded by varying the value of the START code of the data packets. When a DMX512 or other data packet with a NULL START code or “color” packet is received by the controller, the controller interprets the frames to be intensity control data wherein each frame can correspond to a particular light-emitting element or group of light-emitting elements. The color packet can provide data for the generation of a particular temporal color sequence or a temporal color sequence that is random or any other lighting sequence.
