20090279173 | APPARATUS AND METHODS FOR PROVIDING A STATIC INTERFEROMETRIC DISPLAY DEVICE - Disclosed are apparatus and methods for fabricating a static interferometric display device. A plurality of sputtering modules is used to form static interferometric elements on a substrate. These elements each have a plurality of interferometric sub-elements that each has an interferometric stack. A first sub-element of each element is formed so that an interferometric modulation of light due to the first element's stack transmits at a first color, and a second sub-element of each element is formed so that a second color is transmitted. The sub-elements of each element are arranged with respect to each other so that all of the elements appear as a third color to a user if all the sub-elements of each element are left unmasked. A printing system is then used to mask one or more sub-elements of one or more elements so as to form, with the elements, a static image having multiple colors. | 11-12-2009 |

20100134890 | FOCUS ENHANCING ELECTROMAGNETIC WAVE PROPAGATING DEVICE - A focus enhancing electromagnetic wave propagating device includes a main body formed with a main wave-propagating structure (MS) for focusing an electromagnetic wave into a focusing light spot, and an auxiliary wave-propagating channel (AC) for allowing the wave to propagate toward the focusing light spot. A phase difference is present between the wave after traveling through the MS at its exit end and the wave after traveling through the AC at its exit opening, such that constructive interference is generated at the focusing light spot therebetween. The required phase difference is a function of a distance between the focusing light spot and the exit end of the MS, a distance between the focusing light spot and the exit opening of the AC, velocities of the wave after traveling through each of the MS and the AC, and angular frequencies of the wave after traveling through each of the MS and the AC. | 06-03-2010 |
20110134532 | Modified Michelson delay-line interferometer - In an optical etalon with a fixed FSR determined by the cavity length, the time delay is adjusted by an etalon surface coating. The proper cavity length is chosen to achieve a desired FSR, and the coating is independently selected to obtain a desired time delay. | 06-09-2011 |
20110149398 | Instant messaging method-much faster than light communication - Described is a means for communication, enabling message transmission faster than the speed of light between two separated locations. A photon source feeds a splitter, which allows a single photon to split between flowing down the left input side and the right output side. On the left, the photon enters a phase splitter, which produces an in-phase and inverted phase signal. With the delay switch at zero delay, both signals arrive together at the combiner with opposite phase, canceling each other out. With the delay switch set to half a wavelength, no cancellation results and the signal passes unabated through the combiner. In this mode, approximately, fifty percent of the photons register at each detector, which are equidistant from the photon source. In the former mode, (delay switch set to zero) much more of the photons appear at the output detector, and no signal appears at the input detector. | 06-23-2011 |
