Abstract: A power meter includes a current sensor sensing a current of a conductor signal transmitted along a conductor and outputting a current signal based on the current, a voltage sensor sensing a voltage of the conductor signal and outputting a voltage signal based on the voltage, and a controller receiving the current signal and the voltage signal and calculating a power factor of the conductor signal based on the current signal and the voltage signal. The controller determines an operating state of a powered device to which the conductor feeds the conductor signal based on the power factor.

Abstract: A power meter includes a housing attached to a conductor, a hall-effect current sensor disposed in the housing and contactlessly sensing a current of a conductor signal transmitted along the conductor, and a voltage sensor disposed in the housing and contactlessly sensing a voltage of the conductor signal.

Abstract: Described is a polish product, and particularly to a shoe or leather care product, in the form of a paste. The product is essentially free of volatile components (organic components as well as water). It comprises a wax component in an amount in the range of from 20-60%, a non-aqueous, non-volatile liquid component, wherein non-volatile is defined as not being an organic volatile substance having a vapor pressure of greater than 1 torr (0.13 kPa), in an amount in the range of from 20-60%, and a fatty component, preferably a fatty acid, in an amount of 1 to 40 wt %, preferably 5-15% all percentages being weight percentages based on total shoe care product.

Abstract: The self-propelled vehicle intended to move in an essentially circular space has a central load-bearing structure made of frames placed in a longitudinal direction. Sets of jacks are arranged in transverse planes perpendicular to this direction and bear at their end a set of driving elements. Each jack has hollow rods of different diameters that are disposed concentrically about a longitudinal axis of the jack. These hollow rods are connected to one another and to the jack by a member for rotating the jack together with the hollow rods about the longitudinal axis.
