Abstract:
A method is disclosed for scanning a transparency (28) with a template (26, 126, 226, 326, 426), comprising: placing a template (26, 126, 226, 326, 426) on a scan bed (32); locating a transparency (28) in a window (84) of the template (26, 126, 226, 326, 426); passing a first light through a first aperture (86, 94) in the template (26, 126, 226, 326, 426) during a first scan of the transparency (28); passing a second light through the first aperture (86, 94) in the template (26, 126, 226, 326, 426) during a second scan of the transparency (28); and aligning a first electronic image (102, 104, 106) from the first scan and a second electronic image (102, 104, 106) from the second scan based on sensed light through the aperture (86, 94). A template is also disclosed.
Abstract:
Systems 100 and methods 400 for transmissive optical sensing of media information encoding are disclosed. In addition, print media 108 and methods of making print media are disclosed. One embodiment of an exemplary method, among others, includes, advancing a portion of a print medium 108 through a transmissive sensor assembly 106, the portion of the print medium 108 having a barcode 110, the barcode 110 being minimally transmissive of a set of light wavelengths, and the barcode 110 being encoded with at least one type of information corresponding to the print medium 108; transmitting light at the set of light wavelengths substantially absorbed by the barcode 110 through the print medium 108; and detecting changes in the light transmitted through the print medium 108, the changes being produced by the substantially absorptive barcode 110.
Abstract:
A one-piece housing holds an image sensing module having a transparent image sensing surface and a document drive roller in close alignment. A cover closely fits around the housing and is positioned in close alignment with respect to the housing. The cover means and housing cooperate to define a document entry path in which a plurality of sensors are located: a set of document-skew-detecting sensors and a set of document-insertion-detecting sensors, the sets of sensors acting independently of each other. The number and spacing of the sensors in the set of document-insertion-detecting sensors is such that the narrowest expected document encounters at least one such sensor. The cover means and housing also cooperate to define a document scanning path and one or more document exit paths. The cover means includes a chute adjustable to either of one of two positions, the chute cooperating with the cover means and housing to define a first document exit path on the opposite side of said scanner from the document entry path and a second document exit path on the same side of the scanner as the document entry path. The cover means includes front and rear covers, the covers including means for interlocking and positioning the front and rear covers with each other and with said housing.
Abstract:
A display apparatus (1) has an integrated scanning unit 20 to scan a document placed on a scanning area. The scanning unit (20) has an image sensor (30) to capture an image of the document, and the image sensor faces the scanning area. A display unit (10) of the display apparatus displays the captured image. The display apparatus (1) also has a support (50) which supports the display unit (10) above the scanning area.
Abstract:
A system to determine the presence and width of a media within a printing system is disclosed which includes a pair of adjustable media guides is provided about a carriage and is axially spaced apart along the length of the carriage. The guides maybe manipulated along a horizontal axis in a sliding, synchronized manner and such that the center line of media is maintained along the centerline of the print station. A sensor is provided and affixed to the carriage, the sensor being operable for emitting an optical signal through an aperture located in the carriage. At least one of the guides includes an obstruction which may protrude into the path of the optical signal at defined locations.
