Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and / or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

An objective optical system for focusing light from a light source onto optical recording media includes an aperture control filter with a diffractive optical function formed as a glass plate with an aperture control structure on one side and a diffractive optical structure, such as a plastic diffractive optical element adhered to the glass plate on the other side, and an objective lens. The objective optical system focuses three light beams of three different wavelengths at three different numerical apertures onto desired positions of three different recording media with substrates of different thicknesses, such as a BD (or an AOD), a DVD, and a CD, that introduce different amounts of spherical aberration in the focused beams. The objective optical system provides compensating spherical aberration to the three light beams while keeping constant the distance between the aperture control filter with a diffractive optical function and the objective lens.

The present invention provides multiple poly(vinyl butyral) layer interlayers that can be used in multiple layer glass panel type applications that require a high level of impact protection, for example in hurricane protection applications or in bullet proof glass applications. This effect is achieved by forming a poly(vinyl butyral) interlayer that has a relatively stiff poly(vinyl butyral) inner layer disposed between two relatively soft outer poly(vinyl butyral) layers, where the stiffness difference is achieved by a plasticizer differential that is achieved at least in substantial part by a residual hydroxyl content difference among the poly(vinyl butyral) layers.

A single plate flatbed scanner utilizing a single sensor to detect both opening of a lid covering the plate and the leading edge of an automatically fed document. The flatbed scanner includes a contact glass plate defining a flatbed scanning area where a document to be scanned may be manually positioned. An automatic document feeder (ADF) scan window where ADF-fed documents are scanned is defined within the flatbed scanning area. An image sensor is maintained at a fixed position in the ADF scan window while scanning ADF-fed documents. To scan a manually fed document, the image sensor moves under the flatbed scanning area so as to scan an image of the document. Since the ADF scan window and the flatbed scanning area both are defined in the same area of the contact glass plate, a document inadvertently left on the contact glass blocks the ADF scan window and prevents the scanning of an ADF fed document. A single sensor is utilized to detect the opening of the ADF which uncovers the contact glass to allow manual placement of a document. Detecting the opening of the glass plate cover is used to determine whether or not a document has been left on the glass plate after scanning. The same sensor is also utilized to detect the leading edge of an ADF fed document to initiate the scanning process at the precise time the document reaches the ADF scan window.
