  • Patent number: 8685293
    Abstract: Our invention allows for control of particle formation at the nanoscale, providing a means to control nanoparticle and nanostructure formation using feedback on the fly from nanoparticle characteristic analysis and optimization/knowledge extraction control algorithms. A closed loop feedback controller causes the interaction of a shaped flaser pulse with a substrate. The substrate can be one or more solid, liquid or gas or any combination thereof. Nanoparticles are produced and their characteristics are measured. The measured characteristics are compared with the desired nanoparticle characteristics. If the measured and desired characteristics are not equivalent, the closed loop feedback controller modifies the shape of the laser pulse and the next cycle begins. With successive loop of the control process the difference between the desired and measured characteristics converges until they are equivalent.

    Abstract: Improved treatment apparatus (120, 152) is provided for the treatment (e.g., molding, heating and/or curing) of objects such as parts or part precursors (148, 170) including wireless detection of a temperature parameter related to the objects during treatment thereof. The objects include associated microwire-type sensors (150, 174) which have characteristic re-magnetization responses under the influence of applied, alternating magnetic fields. The apparatus (120, 152) have treatment chambers (122, 153) sized to hold the objects to be treated, with one or more antennas (132, 124, 166) proximal to such objects and operable to generate interrogating alternating magnetic fields and to detect the responses of the sensors (150, 174). The detected temperature parameter information is used by an apparatus controller (146) to maintain desired ambient conditions within the treatment chamber (122, 153).

  • Patent number: 8197622
    Abstract: The disclosure relates to systems and methods for detecting features on billets of laminated veneer lumber (LVL). In some embodiments, an LVL billet is provided and passed through a scanning assembly. The scanning assembly includes an x-ray generator and an x-ray detector. The x-ray generator generates a beam of x-ray radiation and the x-ray detector measures intensity of the beam of x-ray radiation after is passes through the LVL billet. The measured intensity is then processed to create an image. Images taken according to the disclosure may then be analyzed to detect features on the LVL billet.

  • Patent number: 8163224
    Abstract: An equipment for metal-laser sintering process includes a powder layer forming unit, an irradiation unit which irradiates light beams, a correction target on which a correction mark serving as a fiducial in correction of the irradiation points of the light beams is formed, and an imaging camera which takes an image of the correction mark. The correction target is formed of a material which is melted by irradiation of light beam so as to be formed a through hole. The correction target is disposed on the substrate and the light beams are irradiated to penetrate the correction target so that the correction mark is formed. Subsequently, the imaging camera takes an image of the correction mark and the location of the correction mark is measured, and thus, correction of the irradiation points is performed.
