Abstract: A device that supports a remote identifier for permanent cathodes in the electro-winning process. A preferred embodiment of the invention provides a support for a proximity identification device for permanent cathodes that, when interconnected with a remote system, provides for a record of its behavior and position in time of each cathode during its useful life in an electro-winning process.

Abstract: Apparatus and a method for compensating production or operationally-induced inaccuracies in the binary-weighted electrodes of a high-resolution digital phase modulator of, for example, a fiber optic gyroscope. Programmable correction values are employed to increase the accuracy of each binary-weighted planar electrode. In the invention, a less significant component of the binary drive signal, if appropriate after compensation in a low resolution digital-to-analog converter, is converted into an analog signal that is applied to a specific or a separate additional electrode of the digital phase modulator.

Abstract: A synchronous serial bus with timing information implemented in the bus standard protocol is provided for a bi-directional serial multi-channel data interchange between locally dedicated measuring instruments in a distributed configuration and/or with a data processing unit. This provides synchronized interchange of data between the instruments wherein each instrument is provided with an allocated controller. The invention permits one to employ a simple, preferably standardized, bus protocol. Wiring structure is considerably simplified for a complex multi-sensor system.
