Abstract:
PROBLEM TO BE SOLVED: To provide an MEMS electrostatic device which operates at a lower and more predictable operating voltage. SOLUTION: An intermediate portion 80 of a multilayer flexible composite material laminated on a substrate is retained at a predetermined position regardless of application of electrostatic force, wherein a predetermined air gap is maintained and its distance is relatively fixed from a microelectronic surface 10 of a lower part and may be reduced up to zero. A movable end portion 100 of the flexible composite material curls by itself unidirectionally due to a difference in thermal expansion coefficient between composite material layers. The end portion 100 moves in response to the electrostatic force, and as a result a distance that the flexible composite material separates from the microelectronic surface 10 changes. The device is disposed so that it may selectively cause electromagnetic radiation to pass through a pathway or block the pathway. A material used for an attenuator is selected so that it may cause various types of electromagnetic radiation to pass through, reflect or absorb. A plurality of electromagnetic attenuators are disposed in an array, and their subsets are selectively operated. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus capable of identifying a source of electromagnetic emission based on the characteristic of the electromagnetic emission, an associated method, a computer device, and a program product of a computer software. SOLUTION: This electromagnetic emission source identification device is equipped with a sensor device 200 constituted so as to sense the electromagnetic emission from the source 700, a data transmitter 400 constituted so as to communicate with the sensor device 200 and to transmit sensed emission data from the sensor device 200, and a computer device 600 constituted so as to communicate with the data transmitter 400, to determine at least one of an identification indicator corresponding to the source 700, an operational characteristic indicator and an accessory characteristic indicator, and to process digital emission data corresponding to the sensed emission data.
