Patent CA-2143046-A1 (CA)
Inventor: ROOSMA ANDRE H
IPC: H04L12/56
Filed: 1995-02-21
Abstract: Apparatus for monitoring a flow of ATM cells in which a measured value is calculated in all cases. A 'leaky bucket' mechanism known for this purpose has too few degrees of freedom to be able to monitor the flow of cells accurately enough for it to be possible to deduce from cell flow variations whether a (temporary) cell rate increase is the consequence of an unavoidable variation induced by the transmission system or of an unduly high cell rate (which is in fact avoidable) on the part of the system users. The operation of the apparatus can be adjusted better to the cell flow characteristics if the measured value (CVn) is a function of a previously calculated reference arrival time (RATn) and the actual arrival time (ATn) of the arriving cell. The reference arrival time is, in turn, a function of the reference arrival times (RATn-p, RATn-q, ...) of one or more preceding cells (n-p, n-q, ...) and of the actual arrival times (ATn-p, ATn-q, ...) of that same one or more preceding cells. In formula form: CVn =f1(RATn, ATn), where RATn = f2(RATn-p, ATn-p , RATn-q, ATn-q, ...) <IMAGE>

Patent CA-2168805-A1 (CA)
Title: Differential pressure indicators
Inventor: CASSIDY RONALD FREDERICK
IPC: G01L19/12
Filed: 1996-02-05
Abstract: A differential pressure indicator has a piston across which inlet  and  outlet  pressures  are  applied  with  a  spring preventing movement  of  the  piston until  a  predetermined differential pressure is exceeded.  At this point, a port is opened to allow the  inlet pressure  to be applied to an indicator button to move the indicator button from a retracted position to an operative extended position to indicate that the pressure differential has been exceeded.  The use of fluid pressure to operate the indicator button applies a large force to the indicator button and allows it to be securely held in the inoperative position to guard against accidental movement by high G-forces.
