A slip ring transmitter for electrically connecting assemblies of rotary-table machines is described and comprises a slip ring with a signal unit for transmitting signals and/or data and with a power unit for transmitting electrical power. As the signal unit is formed such that it is modularly detachable can in particular be axially drawn off from the power unit, the signal unit can be inspected and/or replaced separately from the power unit. This improves the reliability of the transmission of signals and/or data and enables individual optimization of the power unit.

This invention relates to methods and materials for slip ring grinding of a generator rotor, without the need of dismounting the slip ring from the rotor of the generator, and allowing the grinding process to be performed whilst the generator is on full-load operation. As such the methods and materials of the present invention differs from current solution. Whilst allowing on-line grinding of the slip ring, the current solutions require low-speed rotations and accordingly operational shutdown of the generator. Allowing on-load grinding, the present invention greatly shortens the downtime of the generator and to perform maintenance on the slip ring beyond the provided standard maintenance schedule.

An analyte meter to detect an analyte concentration level in a bio-fluid sample may be cleaned and disinfected with a cleaning liquid without harming electrical and internal meter components. In some embodiments, the analyte meter is washable and immersable and may include a sealed sensor connector, sealed battery connector, and possibly a sealed USB connector that may be subjected to a cleaning liquid without the liquid entering an internal chamber of the analyte meter and contacting internal electronic components. In some embodiments, a sealed display screen and sealed keypad are provided such that liquids are prevented from entering the internal chamber. Manufacturing methods and systems utilizing the analyte sensors are provided, as are numerous other aspects.
