Abstract: A system for controlling RF power supplies applying power to a load, such as a plasma chamber, includes a master power supply and a slave power supply. The master power supply provides a control signal, such as a frequency and phase signal, to the slave power supply. The slave power supply receives the frequency and phase signal and also receives signals characteristic of the spectral emissions detected from the load. The slave RF power supply varies the phase and power of its RF output signal applied to the load. Varying the power controls the width of an ion distribution function, and varying the phase controls a peak of the ion distribution. Depending upon the coupling between the RF generators and the load, different spectral emissions are detected, including first harmonics, second harmonics, and, in the case of a dual frequency drive system, intermodulation distortion.

Abstract: The described embodiments relate to multichannel luminaires (102, 212, 404) that employ a color coefficient matrix (CCM) that can be used to adjust an operation of the multichannel luminaires according to their contribution of light to an area (112, 402).

Abstract: Computing devices are now used for various purposes ranging from monitoring a refrigerator to driving automobiles. Protecting the data and logic within the chips of the computing devices is essential to ensure reliable operation. When a particular partition of a chip is powered-up but the logic of the partition is not reset, the logic will be in an unpredictable random state. To operate in a secure environment, it is necessary to start the operation of the logic from a known state and not a random state. To ensure the logic is operating in a secure environment, a digital reset detector circuit (DRDC) is provided that indicates if the logic was reset after power-up. The DRDC can ensure chips are secure from attacks involving reset deprivation upon power-up and help protect various secure and secret assets in a chip, including customer keys.
