    摘要： Display apparatus for presenting data in visual form having panels provided with passages in which display elements, such as balls, are movably positioned and means for selectively moving the balls in their passages between their operative visible positions and their inoperative positions to cause the balls to form or delinate characters. The display apparatus may include a plurality of such panels connected in an endless belt and movable before an opening or window so that the data on more than one panel may be visible at a single time. The means for moving the balls may be jets of air delivered by nozzles mounted on a carriage movable relative to a panel when it is in a predetermined position.

    摘要： In a system for transmitting packets over a link between a compressor and a decompressor, a method is provided for implicit packet type identification. A set of implicit packet transmission characteristics including at least first and second characteristics is selected, and the compressor is operated to assign the first and second transmission characteristics to packets of first and second packet types, respectively. The decompressor is operated to detect transmission characteristics of packets received by the decompressor, and to thereby identify a received packet as being either a first or second packet type. Usefully, header free packets comprise one of the packet types.
