Abstract: A one-piece molded plastic computer workplace organizer can be screwed to a baseplane such as a pull-out keyboard shelf of a computer desk. A mouse pad is located to the front of the organizer unit which provides a passageway for retaining the mouse cord in place so as to overcome the common problem of the mouse unit working its way to the rear and falling off the shelf edge, especially when the shelf is being pulled out. Storage for several 31/2" diskettes is provided with asymmetrical bistable support positioning: a nearly upright rearwardly-inclined working position and a low profile forwardly-inclined storage position. With the organizer mounted on the pull-out keyboard shelf, upright diskettes will be automatically flipped forward to the low profile position by the shelf edge for storage under the desk counter top when the shelf is pushed back into the storage position.
Abstract: A method and optical system auxiliary input calibration arrangement accurately and reliably discriminate between a user generated image and a video source generated image, such as one produced by a computer. The calibration arrangement includes amplifier devices for increasing the strength of a video information signal indicative of the video generated image, and a user generated auxiliary input signal indicative of an auxiliary input light image, without increasing spurious ambient light signals. A discrimination circuit generates a detection signal whenever the amplified information signals are greater than a predetermined reference level signal. A microprocessor calculates the appropriate predetermined reference level signal based upon ambient lighting conditions, the strength of that portion of the information signal indicative of the video image, the type of optical system and the distance the optical system is disposed away from a viewing surface.

Abstract: An audio/video media package storage structure is formed using side rails, partition rails and spacer tubes. The side rail inner surface contains: a bottom flange; a row of interleaved long and short posts; a shelf beneath the posts and above the bottom flange, the shelf having notches centered between adjacent long posts. The rail can support packages of up to three different sizes at one time. Thin packages are supported between adjacent long and short posts and rest on the shelf. Thick packages are supported between adjacent long posts and rest on the bottom flange. Medium-sized packages fit within the notch on the shelf and rest on the bottom flange. The shelf and the bottom flange have protuberances centered between adjacent long and short posts and adjacent posts, respectively, to allow the packages to shift from a forwardly to a rearwardly-oriented display position. Each end of the side rail has a tunnel adjoining the bottom flange for inserting a spacer tube.
Abstract: A new and improved display control system which includes a logic arrangement for causing a displayed image indicative of a portion of a corresponding larger image to be displayed upon an input command from a user. A line control circuit responsive to user input commands enables the displayed image to be shifted visually from a current visualization position, up or down, row by row for line pan visualization of corresponding portions of the larger image. A pixel control circuit also responsive to user input command enables the displayed image to be shifted visually from a current visualization position right or left, column by column, for column pan visualization of corresponding portions of the larger image. The line control circuit and the pixel control circuit operate independently of one another or in combination with one another to achieve any desired panning effect.
Abstract: A compiling system which can mass produce individually customized media, such as videotapes in a highly efficient and cost effective manner. High volume production is realized by matrixing synchronized system resources, such as videodisc players, videocassette recorders, and graphic generator units. The resources are managed using a predetermined client/server model of computing over a local area network. The resources are synchronized by supplying all time dependent system nodes with the same time base criteria, which in turn, is also utilized to synchronize non-time dependent resources.
Abstract: A plastic open frame basket is made by molding from plastic material, a tapered body portion, having integrally interconnected smoothly contoured longitudinal rib members and cross members in an interconnected, open frame configuration. A plurality of raised diagonal parting lines extend between said outer and inner corners formed by adjacent cross members to define a stepped configuration, thereby enabling the resulting plastic molded open frame basket to be made from a relatively inexpensive mold apparatus.
