Title: Method and apparatus for stabilizing transient control in amplified optical networks
Inventor: WERNER DIETER
IPC: H04B10/29
Filed: 2001-01-22
Abstract: An apparatus and method are described for controlling response to power transients in an optically amplified wavelength division multiplexed (WDM) network when WDM optical channels are added and dropped, during network reconfigurations, during failure events, and so on. In one embodiment, a variable bandwidth filter circuit operates at a first prescribed bandwidth during a first time period io to detect a change in signal power (i.e;., power transient) caused by a transient event, and operates at a second prescribed bandwidth that is less than the first prescribed bandwidth after the first period of time elapses, e.g., .TAU.0 + .DELTA..TAU. to substantially suppress low level signal variations, such as remnants of the power transient. In this way, the power transient related to the actual transient event will be preserved to trigger control circuitry, e.g., amplifier gain control based on input power changes, while the remnants will be filtered out to prevent unwanted responses by the control circuitry, e.g., remnants misinterpreted as actual transient events.

IPC: F16K37/00
Filed: 2001-03-16
Abstract: A method and assembly (kit) are provided for use by propane tank service personnel to detect escaping gas in propane tank systems. In one embodiment, the standard connection between the regulator and tank service valve is replaced with a permanent valve arrangement including a main connection between the regulator and valve and a valve unit disposed in a branch connection of the valve assembly.  In a second embodiment, a permanent valve assembly is screwed into a pressure port in the tank regulator system. A separate pressure gauge is individually assigned to tank service personnel and adapted to be carried by such personnel in testing the pressure in the propane tank. The pressure gauge is affixed, e.g., through a hose, to a valve unit connector including an actuator, e.g., a valve stem operator, for actuating the valve unit. When the pressure gauge is connected to the valve unit, the latter is actuated to provide an immediate reading of the tank pressure (depending, in the second embodiment, on the location of the pressure port). A determination is made from this reading whether the tank is out of gas, and if the tank is out of gas, the service valve is turned on, gas introduced, the service valve turned off and a further pressure check made to determine whether gas is leaking. In the second embodiment, the valve unit includes a valve housing with a restricted (0.054 inch or smaller) inlet.
