Title: Vacuum cleaner actuator switch
Inventor: CREVLING ROBERT L
IPC: H01H35/18
Filed: 2001-06-26
Abstract: A switch assembly for a wet/dry vacuum cleaner is disclosed. The switch assembly includes a switch having a movable arm adapted to connect first and second conductive terminals with a rocker arm pivotally attached to the switch. The rocker arm is operable by an actuator button and a de-- actuator button which are user engageable. Depending upon which of the de-actuator and actuator buttons are depressed, the rocker arm assumes a given position relative to the switch, which in turn results in an on or off position for the switch. An automatic shut-off assembly is operable in conjunction with the switch assembly to tum the switch to an off position in the event that the level of liquid within the tank rises beyond an acceptable level. The switch assembly enables the operator to manually override the automatic shut-off assembly.

Abstract: Commercially available optical fiber amplifiers have gain over a large optical bandwidth, and for many applications, especially long distance fiber communications, developing techniques to flatten the gain of EDFA's is important. High gain amplifiers give rise to gain ripple and are thus more difficult to flatten effectively and efficiently. The invention provides a method of amplifying a signal in an optical fiber in an optical fiber amplifier having a pre-determined operating temperature range, whereby the temperature of the fiber in the pre-determined operating temperature range is maintained, and the fiber has an optimal length so as to minimize gain ripple in the amplifier over the operating temperature range. The invention also provides an optical fiber amplifier having an optimal length of fiber, a heater (2) and a temperature monitor both coupled thermally to the fiber. The temperature monitor (3) is responsive to the temperature falling below the pre-determined operating temperature range of the amplifier to energize the heater, and is responsive to the temperature rising higher than the pre-determined operating temperature range of the amplifier to de-energize the heater.
