1) FIBER OPTIC GYRO Winding Machine:
Fiber optic gyroscopes (FOGs) have gained greater acceptance in recent years in both commercial and military applications. FOGs have been shown to be an improved method of providing accurate
navigational information and control in guidance systems as compared to conventional mechanical gyroscopes. However, the process used to manufacture FOGs, particularly with the winding of the optical fiber onto the product spool, has a very low throughput.
Even with a semi-automated machine, it normally requires up to a week and the full commitment of a technician to wind one such coil. Where has we reduced the time up to 45 to 60 Minutes by giving a solution with QUADRAPUL Winding machine which we have bought from IWT Germany. Efforts are currently being made to fully automate the coil winding process and to increase the rate of production, as well as the quality of the winding on the product spool.
However, the intricacies involved in the winding of the complex patterns make touch labor in the manufacturing process a necessity. In order to minimize the need to have an operator constantly monitor the winding process for errors, it was decided that a machine vision system could help mitigate the problem. The vision system would detect winding errors and provide feedback to the coilwinder machine, which would then correct the errors.
Clock sources used for synchronization in telecommunications networks are rated by quality, commonly called a stratum. Typically, a network element uses the highest quality stratum available to it, which can be determined by monitoring the synchronization status messages (SSM) of selected clock sources.
Synchronization sources available to a network element are:
Local external timing
This is generated by an atomic Caesium clock or a satellite-derived clock by a device in the same central office as the network element. The interface is often a DS1, with sync-status messages supplied by the clock and placed into the DS1 overhead.
A network element can choose (or be configured) to derive its timing from the line-level, by monitoring the S1 sync-status bytes to ensure quality.
As a last resort, in the absence of higher quality timing, a network element can go into a holdover mode until higher-quality external timing becomes available again. In this mode, the network element uses its own timing circuits as a reference.
A timing loop occurs when network elements in a network are each deriving their timing from other network elements, without any of them being a "master" timing source. This network loop will eventually see its own timing "float away" from any external networks, causing mysterious bit errors—and ultimately, in the worst cases, massive loss of traffic. The source of these kinds of errors can be hard to diagnose. In general, a network that has been properly configured should never find itself in a timing loop, but some classes of silent failures could nevertheless cause this issue
We are also focusing on microwave products which will go up to 40Ghz, as well as Production of a wide range of microwave Components, Super Components, Subsystems.
