  • Patent number: 6806991
    Abstract: In one embodiment, the present invention is directed to a system that enables controllable positioning of a fully-released micro-stage. The fully-released micro-stage may be assembled onto a detector substrate that enables micro-positioning feedback. A payload structure (e.g., a lens, mirror, manipulator, and/or the like) may be assembled or coupled onto the fully-release microstage. Snap connectors may facilitate the mechanical coupling associated with assembly of the various components. The fully-released microstage may be actuated by motion amplified actuators that are coupled to anchored flexures. Moreover, the actuation of the fully-release microstage may produce fully decoupled movement by coupling the actuators and respective flexures to the stage in a mirrored fashion.

  • Patent number: 6807009
    Abstract: The invention provides an optical device including a polarization diversity unit for receiving an input optical signal and producing two beams of light having a same polarization state therefrom, a beam swapping element disposed for receiving the first and second beams of light and for redirecting the two beams of light to a same overlapping area of a modulator, and a reflective surface for reflecting the two beams of light back to the polarization diversity unit where they are combined to form an output optical signal. The beam swapping element is designed and positioned such that the first and second beams of light swap positions upon reflection from the reflective surface and trace out the other's optical path. Advantageously, this optical arrangement essentially eliminates all PDL and PMD.

  • Patent number: 6798555
    Abstract: A tapping electrode for a lower electrode film and a tapping electrode for an upper electrode film are provided on one side of an area around a substrate. By placing the electrode-tapping elements on one side, for example, applying the electrochromic element to an automobile antiglare mirror, the effective field of the mirror is increased to contribute to safety. A mirror ring that surrounds the outer circumference of the mirror can be made slim, enhancing a smart look from the viewpoint of design. Also, in comparison with a case in which the electrode is tapped on two or more sides, the present design makes it possible to secure the same effective visibility with a lightweight design.

  • Patent number: 6795230
    Abstract: A self-assembled molecular color switch is formed on a substrate and comprises coupled coaxial rotors and non-coaxial stators, with each rotor rotatably connected to two stators, to form molecular planes wherein all rotors at rest are parallel to the substrate and orthogonal to an electric field. The color switch employs a novel chemistry for producing a molecular film having a field switchable color. More particularly, it is a chemistry that provides for relatively thick self-assembled molecular layers collectively having print-like optical density. Further, a means for bi-stable color switching is provided.

  • Patent number: 6791093
    Abstract: The invention provides a technique for correcting gamma ray intensities detected to account for variation in attenuation effects with energy. The corrected intensity values enable more accurate isotopic analysis to be conducted and render such techniques applicable to low level emission cases. The technique is particularly useful in investigate waste materials with a gamma emitting content which needs to be determined. The attenuation is corrected for using a bi-modal function to account for the attenuation effects arising from low and high atomic mass components of the material in which the emitters are present.

  • Patent number: 6791101
    Abstract: Methods and apparatus for directing radiation to and from a sample to be scanned. In one example, first radiation propagating along a first axis is reflected off of the first axis so as to impinge on the sample. In response to the first radiation, the sample emits second radiation, which is directed to a detector. In one aspect, the second radiation is received directly from the sample by a reflector, which reflects the second radiation such that it travels substantially through air to impinge on the detector. In another aspect, the second radiation is directed such that it travels toward the detector in a direction having a significant vector component parallel to the first axis. In yet another aspect, a detection surface of the detector is oriented essentially perpendicular to the first axis and adapted to detect at least some of the second radiation traveling in a direction non-parallel to the first axis.

  • Patent number: 6778310
    Abstract: Optical pulses at a given repetition rate (f) are obtained by modulating an optical signal by means of a Mach-Zehnder modulator. The modulator is driven by means of a driving signal including, in addition to a sinusoidal component at a frequency (f/2) half the repetition rate (f) of the pulses, at least one odd harmonic of the sinusoidal component. Very short optical pulses can thus be generated without giving rise to undesired side effects such as ringing in pulse tails.

  • Patent number: 6777668
    Abstract: A method and apparatus are provided for adhesive bonding of a backing plate for a sensor assembly to a vehicle window, especially a windscreen of a passenger car or truck. The backing plate has an adhesive layer and is heated at least in the area of the adhesive layer by a heating device until the adhesive layer is softened sufficiently to carry out adhesive bonding. The backing plate is transferred into a contact pressure device and the contact pressure device presses the backing plate with the adhesive layer on to the vehicle window for a predetermined length of time. In order to improve the usability of such a method in the context of mass production, it is provided that the heating device emits infrared radiation, heating of the adhesive layer being carried out until it has softened sufficiently by positioning the backing plate with the adhesive layer facing the heating device at a close spacing for a predetermined length of time.

  • Patent number: 6765194
    Abstract: An arrangement for determining measured values, in particular measured pressure values, strain values, or temperature value, using a plurality of optical fiber Bragg grating sensors. The optical fiber Bragg grating sensors are combined to form various arrays of optical fiber Bragg grating sensors that are arranged one behind the other, are connected by fiber optics, and exhibit different frequency selectivities. Delay elements are assigned to these arrays. The Bragg grating sensors receive a uniform query signal representing a time-differentiated, frequency-selective light. The frequency-selective Bragg grating sensors of the various arrays generate partial signals. The partial signals, separated temporally from one another by the delay elements, form a sequence of partial signals.
