  • Patent number: 9482687
    Abstract: A device for measuring angle and angular velocity or distance and speed of a moving part is described. The device has a sensor which is or can be arranged in a stationary manner and an encoder which is or can be arranged on the moving part and, together with the sensor, generates a modulation signal to be demodulated by the sensor. For the frequency measurement which is needed to measure the angular velocity/speed, the encoder has a structure which reproduces a periodic pattern and is interrupted by at least one index area for the angle/distance measurement. In the index area, the encoder has a substitute pattern which differs from the periodic pattern by at least one physical variable which can be detected by the sensor but has a structure which also enables the frequency measurement in the index area.

  • Patent number: 9203243
    Abstract: A load leveling system and method capable of controlling switches such that it appears to a generator that the load is constant. The purpose is to prevent high-load simultaneous switching or multiple synchronous switching from damaging sensitive equipment. The present invention utilizes a central controller communicating to a number of switches such that the switches turn off and on in a synchronized, serialized manner. As one switch turns “off,” another should be turning “on” until a cycle is completed. In this manner, the generator will only see a single “on” and a single “off” load per cycle. The various switches are scheduled such that, ideally, the power load seen by the power source has emissions of no more than one PWM load superpositioned with zero or more constant, non-modulated loads.
