Abstract: A plurality of scanner bars is arranged in precisely located holes in the frame of a media handling device to detect the passage of the lead and trail edge of media. The multiplicity of scanner bars, arranged linearly at a right angle to the direction of motion of the media, is sampled at some frequency. The scanner bars give not only arrival and departure time of the media from each scanner bar location, but also making some assumptions about the shape of the media, information about the orientation of the media relative to the direction of motion. This information can be used to diagnose improper media handling mechanisms upstream of the sensor or provide information to downstream corrective mechanisms. Preprinted test media, such as, ladder charts, etc., can be used to extract velocity profiles and other paper path dynamic characteristics.

Abstract: A data acquisition system includes a product for shipment to an end user, a sensor system removably connected to the product for recording environmental conditions to which the product is exposed, and a computing device, which upon being connected to the product, is operable to retrieve the recorded environmental conditions. The product may be operable to control the operation of the sensor system, or the sensor system may be operable to record environmental conditions independent of the operation of the product.

Abstract: A process for fabricating a full width scanning or printing array in which plural smaller scanning or printing chips are bonded end-to-end onto an glass substrate using a photocurable adhesive to form a subassembly, following which the subassembly is inverted and joined to a second substrate having a conductive surface using a conductive heat activated adhesive.

Abstract: A process for fabricating a full width array in which plural smaller chips are bonded end-to-end onto the metallic covering of an elongated substrate by an electrically conductive heat activated adhesive, in which a photocurable adhesive is used to temporarily retain the smaller chips in position while the heat activated adhesive is cured, the process accommodating the inability to cure the photocurable adhesive through the opaque chips and substrate covering by locating the photocurable adhesive so that it extends outside of the boundary of the smaller chips and forms an adhesive fillet or bridge between one side of the smaller chips and the substrate when cured by ultraviolet light.In an alternate embodiment, the photocurable adhesive is located within the boundary of the smaller chips initially but is squeezed out from below the smaller chips to form the exposed adhesive bridge when the smaller chips are placed on the substrate.
