Abstract: A wireless local area network adapted for use by users traveling on a mobile platform such as an aircraft. The network includes a network server located on the mobile platform, and at least one network access point connected to the server and accessible wirelessly by at least one user portable electronic device over one of a plurality of non-overlapping network frequency channels. The RF characteristics of this wireless network are specifically tailored to meet applicable standards for electromagnetic compatibility with aircraft systems and RF exposure levels for passengers and flight crews.

Abstract: A system 10 and methods for acquiring and archiving images derived from multiple sources with minimal operator interaction and understanding of the archiving computer 11. The system 10 and methods provide for reception of digitized images via modem 24 from a remote source, and the input of images from local sources including a digital photographic image source 25 such as a digital camera or 35 millimeter digitizing camera data back, an optical scanner 23, and digitized images previously stored on magneto-optical disk or digital audio tape. The system 10 also archives and distributes image and document data to multiple destinations, including a magneto-optical drive 22, digital or hard disk drive 15, and to laser or photographic quality continuous tone printers 26, 27.

Abstract: An integrated cache memory device using SRAM cells is disclosed. The integrated cache memory has synchronized write capability and burst read capability.

Abstract: A circuit for stitching and balancing the outputs of two CCD arrays is described. The field of view of a high resolution CCD raster input scanner can be doubled by using a CCD array for each half of the scan. Then the CCD output analog pulses must be stitched together, the dc level equalized and restored to a common value, and the gains adjusted to match the video levels from the two CCD devices. The circuit described herein accomplishes these functions at high data rates and at low cost by stitching the video, eliminating the hold step produced by the sample-and-hold circuit, and adjusting the gains, all at the low voltage levels at which the CCD output signals were originally produced, before amplifying the resultant stitched video to a higher voltage level and converting to digital form.
