  • Cabinet-surface-mounted projection lens and methods
    Publication number: 20070024821
    Abstract: A projection system includes a cabinet having a surface with an aperture therein, a projector disposed within the cabinet, adapted to project light through the aperture in the surface of the cabinet, and a lens disposed in the aperture to project the light onto a screen disposed generally non-parallel to the cabinet surface having the aperture.

  • MEMS release methods
    Publication number: 20060234412
    Abstract: A packaged MEMS device is fabricated by providing a first substrate, forming the MEMS device on the first substrate (the MEMS device including at least one element initially held immobile by a sacrificial material), optionally removing a portion of the sacrificial material without releasing the element, providing a second substrate, forming at least one release port, bonding the second substrate to the first substrate, and removing the sacrificial material through the release port to release the element.

  • MEMS packaging structure and methods
    Publication number: 20060228869
    Abstract: A MEMS article is made by forming a MEMS device on a first substrate, providing a second substrate, depositing a layer of etchable dielectric material, forming at least one lateral post-bond release-etch port by a damascene process using a sacrificial material, and bonding the two substrates together.

  • Specimen stage for charged-particle scanning microscopy
    Publication number: 20060169916
    Abstract: A specimen stage for charged-particle scanning microscopy comprises a non-magnetic platform for supporting a specimen, at least one probe pin assembly including a probe pin for contacting a selected portion of the specimen, the probe pin being electrically insulated from the platform and being electrically coupled to an output, and an elevator mechanism operable to move the platform for bringing the specimen into and out of electrical contact with the probe pin(s), substantially without moving the probe pin(s).

  • Photonic crystal device and methods
    Publication number: 20060078268
    Abstract: A photonic crystal device is fabricated by a method comprising steps of providing a substrate, providing a photonic crystal on the substrate, and etching a cavity under at least the photonic crystal, the cavity having an inner wall adapted to reflect light.

  • Fluid sensor and methods
    Publication number: 20050212531
    Abstract: A fluid sensor for use in an environment having an ambient temperature has a field-effect transistor (FET) comprising a functionalized semiconductor nano-wire, an integral heater disposed proximate to the field-effect transistor to heat the field-effect transistor to an elevated temperature relative to the ambient temperature, and integral thermal insulation disposed to maintain the field-effect transistor at the elevated temperature.
