Abstract: A system for monitoring electrical equipment operative at a medium voltage that is isolated from a low voltage environment includes a transmitter unit that is operative at the medium voltage. The transmitter unit produces an optical signal that is indicative of at least one measured property of the electrical equipment. The optical signal is transmitted via an optical fiber to a low voltage receiver within the low voltage environment.

Abstract: Systems and methods perform simultaneous media transfers, such as video streaming between centralized storage, e.g., a hard drive, that stores data for multiple users, and nodes, in both the record and playback modes. These systems and methods also allow for instant access to live programming and pausing thereof. There is also a central media database, typically implemented in the hard disc(s) of the hard drive, that allows for video storage. High speed broadband Internet access can also be obtained from this system.
