  • Publication number: 20070210031
    Abstract: The described embodiments relate to features in substrates and methods of forming same. One exemplary embodiment can be a microdevice that includes a substrate extending between a first substrate surface and a generally opposing second substrate surface, and at least one feature formed into the first surface along a bore axis that is not transverse to the first surface.

  • Publication number: 20060238603
    Abstract: Systems and methods for printing on a print medium having a light-sensitive labeling layer are disclosed. The system includes a light source adapted to generate a light beam and a reflective surface adapted to deflect the light beam from the light source to a light-sensitive labeling layer of a print medium. The reflective surface is further adapted to rotate to cause the light beam to scan a scan region of the labeling layer. The light beam is adapted to activate the light-sensitive labeling layer of the print medium by causing a chemical change in the light-sensitive labeling layer to form an image.

  • Patent number: 6655794
    Abstract: Methods and apparatus are provided for forming a seal between two or more components using a thermally cured sealing material. One exemplary method includes selectively applying an electrical signal to a heating trace on a first component, applying a sealing material between at least a portion of the first component and at least a portion of a second component, and at least partially thermally curing the sealing material using thermal energy generated by the application of the electrical signal to the heating trace.
