Patent EP-0292226-A3 (EP)
IPC: H04L29/06
Filed: 1988-05-17
Abstract: Multiport/multidrop computer communication is provided 
over a single communication facility (310) between a 
plurality of central stations (100,101,102) at a central 
location their respective remote stations (320,330,340) at 
remote locations. Outbound transmissions are multiplexed 
from a multiport central modem (300) to compatible 
multiport remote modems (350,351,352). The central 
stations (100,101,102) are monitored to detect which one 
or ones have invited a response from a remote station 
(320,330,340) and one central station is selected. A 
signal is sent to the remote modems (350,351,352) 
indicating the selected central station. The signal is 
combined with the request to send of the invited remote 
computer (500) associated with the selected central 
station to enable use of the return transmission lines. 
The request to send signal line idle or idle code stations 
are monitored to detect which central stations have 
invited a remote. Signaling is by RTS-DCD simulation in 
commercial modems. Another central station is selected if 
return transmission does not begin within a timer 
interval. Fast reset is provided if carrier persists 
after the return transmission has ended.

Title: Variable gas volume flow measuring and control methods and apparatus
IPC: G01F1/34
Filed: 1988-11-23
Abstract: Methods and apparatus are disclosed for measuring gas volume flow rate through a duct (23) including a variable area orifice (24), e.g. in an air conditioning system. Respective sensors (S1, S2) reference the total pressure upstream of the orifice (24) to the static pressure downstream, and a first signal representing the differential pressure is fed, with a second signal representing the open orifice area, to a control computer (31) which calculates the gas flow rate through the duct (23) on the basis of the signal values and information in a stored gas flow volume database. The database is constructed from values of the first and second signals generated at known volumes of air, preferably as a single, non-dimensional curve for all amplitudes of the differential pressure signal. The open orifice area may be controlled in dependence on conditions e.g. temperature, pollution, detected by a sensor (37) downstream of the orifice (24).
