Appl. No.:

12/563597

Inventors:

Martin Moskovits - Santa Barbara CA, US
Qihong Wu - Somerset NJ, US

Thomas Tombler - Somerset NJ, US

International Classification:

G02B 7/02

US Classification:

359819

Abstract:

In general, in one aspect, the invention features an apparatus that includes a plurality of optical elements arranged to form an image of an object. The elements include a first element comprising one or more regions of a polarizing material, the regions being shaped as one or more visual features, a polarizer, and a mounting assembly including a first mount for the first element and a second mount for the polarizer. At least the first or second mount is rotatable with respect to an optical axis between a first orientation and a second orientation. In the first orientation, the visual features are visible in the image of the object and, in the second orientation, the visual features are not visible in the image of the object.

International Classification:

G06F 3/00

US Classification:

710 74

Abstract:

A method for processing input/output request packets (IRPs) directed to Data Volumes having a meta-data extent and at least one data extent begins by initiating an IRP. The IRP is evaluated by a volume filter to determine a meta-data extent to handle the IRP. The IRP is directed by the volume filter to the appropriate meta-data extent. The IRP is redirected from the meta-data extent to at least one data extent associated with the meta-data extent.

International Classification:

G03F 7/20

US Classification:

430323, 430322, 430325, 430326

Abstract:

Methods include providing an article including a substrate, a first layer supported by the substrate, and an interface between the substrate and the first layer. The substrate is substantially transparent to radiation at a wavelength λ and the first layer is formed from a photoresist. The methods include exposing the first layer to radiation by directing radiation at λ through the substrate to impinge on the interface so that the radiation experiences total internal reflection at the interface.
