Abstract: 1+1 Mesh Protection provides 1+1 protection for connections across an automatically routed mesh network, where a connection is setup automatically by using an intelligent signaling and routing protocol. 1+1 Mesh Protection can set up, tear down, and reroute both the working path and protect path across the mesh network automatically based on a specified service profile. 1+1 Mesh Protection interoperates seamlessly with traditional 1+1 protection mechanisms such as APS 1+1 protection in SONET networks.

Abstract: A novel pressure sensor mechanism is provided which includes both a novel pressure sensor assembly and a novel handle for use therewith. The pressure sensor assembly has at least one pressure sensor at its distal end, the pressure sensor having electrodes which are connected through spaced leads to output terminals at a proximal end of the assembly. Even though sensor electrodes and leads may be on facing substrate sections of the assembly, the assembly is designed so as to permit all output terminals to be electrically accessed from the same side of the sensor assembly. An additional output terminal may be provided for preferred embodiments, which terminal is accessible from the same side of the sensor assembly as the other two output terminals, is substantially smaller than the other two output terminals and is connected to one of the other two output terminals by a sensor-ok lead or trace.
