Abstract: An adjustable stand is provided for display devices, such as office equipment, particularly portable computers with integral displays, laboratory test equipment with display devices, home computers, etc., which allows the devices to be supported at a desired height above a support surface and, additionally, allows for the adjustment of the height and of the angle of the display device. The support means provided allows for easy adjustment of the height and angle, while firmly holding the device in the position set for it.

Abstract: Apparatus for indicating the location of particular information, such as instructions, represented by predetermined signals previously recorded on a record medium. An array of light emitting sources is selectively energized to indicate the position of the particular information relative to the length of the record medium while the array is scanned in synchronism with the scanning of the record medium to detect the presence of such predetermined signals. Indexing means sequentially conditions each of the light emitting sources to be energized during scanning; and a temporary storage circuit stores a representation of a detected predetermined signal, until a light emitting source is conditioned.

Abstract: Indexing apparatus for indicating the amount of information recorded on or transcribed from a record medium. A non-linear index scale having, for example, time markings thereon, is moved into view concurrently with the rewind movement of the record medium to a beginning location in preparation of a reproducing, or transcribing operation. The length of index scale viewable by an operator represents the amount of recorded information to be transcribed; and as transcription proceeds, the scale remains stationary and is scanned by an indicator. For an information recording operation, the index scale is moved fully into view and is scanned by the indicator.
