Filed: 1990-06-28
Abstract: A potential transmission-access failing in the IEEE 802.6 protocol is remedied by the use of terminals that sense the activity level on the interconnecting communications lines.  In response to conditions that may give rise to such a failing, each terminal throttles its own transmission rate to improve the transmission capacity allocation of the protocol.  In one embodiment, the terminal that transmits over more than half of the slots in the round trip delay simply throttles itself to one half the slots when it detects that another terminal is transmitting or is wishing to transmit. In another embodiment, even a terminal that is transmitting over fewerthan half the slots in the round trip delay determines the number of unoccupied slots and throttles itself to transmit over not more than half of the number of available slots. In still another embodiment, a terminal wishing to transmit many packets casts a number of reservation bits onto the transmission channel to insure for itself some transmission capacity.  The number of reservation bits sent is equal to a fraction of the available slots.  In yet another embodiment, each terminal throttles itself to take no more than a specified fraction of the remaining transmission capacity.

Abstract: ABSTRACT           Production of a tactile print using an improved silk screen process which provides a product with raised imprinted  surfaces  of  sufficient  local  definition  to permit tactile "reading" of the print.  In the case of a surface  imprinted with  Braille  patterns,  the  process provides a low cost touch-readable imprint of acceptable clarity  and depth  for  use  by  Braille  readers.    The process uses known silk screen procedures using a screen ranging  in mesh per  square  inch  from 60  to  100,  in combination with high viscosity "ink", which may in some instances be non-pigmented.   The process includes the provision of underside spacers, and may also utilize air pressure differential across the thickness of the screen to facilitate flow of the "ink", together with controlled drying rates.
