Abstract: A protection system (80) for a first generator unit (12) connectible by a first switch (24) to a power generating system having at least one additional generator unit with the at least one additional generator unit being connectible in parallel to the first generator unit with the first switch being opened in response to a first control signal to enable the first generator unit to be disconnected from the parallel connection to the at least one additional generator unit in accordance with the invention includes a signal generator (12) for generating a reference signal having a frequency proportional to a frequency of a voltage generated by the first generator unit; a sensor (14) for sensing a common frequency at a point of reference of voltage generated by the generator units of the power generating system; and a controller (14) responsive to the signal generator and the sensor, for calculating a difference between the frequency of the reference signal and the common frequency and for generating the first control signal in response to the difference being greater than a threshold.

Abstract: Surface covering display elements, systems and/or methods are provided. In accordance with one embodiment, a multi-patterned rug display sample, element or unit has at least two different geometric designs and/or coloration schemes across a common surface for simultaneous comparative evaluation by a potential purchaser. The rug display sample may be patterned to include two or more geometric or solid patterns corresponding to patterns available on floor covering products independent of the display sample. Also, the display unit may include a feature rug, color runner, color rug, and/or hang tag.
