摘要:
Methods and structures for reducing the moisture penetration in an optical device such as an isolator, collimator, filters, circulators, and the like. Methods can include placing an optical cover over the opening(s) of the housing of the optical device. The optical cover can be bonded by epoxy or metallic seal. A moisture prevention coating can be placed over the seal line between the optical cover and the housing to further enhance moisture prevention.

The invention relates generally to a new type of electrochromic (EC) window, and a method of manufacturing the same. The EC window of the present invention utilizes a photopolymerizable monomer in a liquid-like solution to allow the entire solution to be cured to a substantially solid form using light instead of heat. The EC window includes a first plate layer, a first conductive layer, a guest host electrolyte/electrochromic layer, a second conductive layer, and a second plate layer. The photopolymerizable monomer may be included in either the guest-host electrolyte or the electrochromic layer

A solid particle flow distribution controller includes an extension skirt configured to be mounted to a discharge skirt at a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The extension skirt includes a plurality of circumferential segments. Each segment is movably mounted to the discharge skirt for movement in an upstream and downstream direction with respect to the discharge skirt. The segments of the extension skirt are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the discharge skirt as needed to improve solid particle distribution among the downstream pipes.

This invention is related to the fields of organic chemistry and nanotechnology. In particular, it relates to materials and methods for the preparation of organic synthons and bridged macrocyclic module components. The bridge macrocyclic module compounds may be used to prepare macrocyclic module compositions such as nanofilms, which may be useful for filtration.

Methods and structures for reducing and/or eliminating moisture penetration in an optical package. The optical package may include (1) a layer of inorganic material placed over the points of the optical package susceptible moisture penetration of the optical package; (2) a portion of hygroscopic material placed over the points of the optical package susceptible to moisture penetration; (3) a layer of hygroscopic material placed on the interior surface of the optical package; and/or (4) a layer of hydrophobic material coated on the optical surfaces of the optical package.
摘要:
An apparatus is presented in which a sample can be accurately repositioned in a spectroscopic and/or imaging apparatus upon multiple insertions, and where the apparatus can be worn by living subjects for extended periods of time. The apparatus additionally reduces the temperature increase and stabilizes the temperature of the sample upon irradiation with an optical source of excitation. Additionally, the apparatus stabilizes the pressure and critical optical properties of the sample and its interface with the apparatus. Alternatively or additionally, the apparatus can be used to alter and/or substantially reduce fluorescence from targeted fluorophores in the sample.

The present invention provides matrixes doped with semiconductor nanocrystals. In certain embodiments, the semiconductor nanocrystals have a size and composition such that they absorb or emit light at particular wavelengths. The nanocrystals can comprise ligands that allow for mixing with various matrix materials, including polymers, such that a minimal portion of light is scattered by the matrixes. The matrixes of the present invention can also be utilized in refractive index matching applications. In other embodiments, semiconductor nanocrystals are embedded within matrixes to form a nanocrystal density gradient, thereby creating an effective refractive index gradient. The matrixes of the present invention can also be used as filters and antireflective coatings on optical devices and as down-converting layers. The present invention also provides processes for producing matrixes comprising semiconductor nanocrystals.

Exemplary embodiments of the present invention illustrate methods to electrically connect multiple layers of a substrate. A first and second layer each has at least one electrical trace on a surface thereof. The substrate includes an interposer structure attached to the second layer and separating the first and second layers on at least a portion of a perimeter of the first and second layers. The method includes a steps for forming a via in the first layer, placing a first electrically conductive substance in the via, placing a second electrically conductive substance on the second layer adjacent said via, and heating an area around said via and said second electrically conductive substance until said first and second electrically conductive substances at least partially melt to form the electrical connection.

A method, and a corresponding apparatus, provide for remote, secure replacement of private keys in a private key infrastructure. The method is implemented as a secure key replacement protocol (SKRP), which includes the steps of receiving a rekey request, where the rekey request identifies a private key for replacement, authenticating the rekey request, replacing the identified private key with a SKRP key, signing the challenge with the SKRP key, and returning the signed challenge. The rekey request includes the SKRP key and the challenge.
