  • Patent number: 10693462
    Abstract: Techniques are described for ground-intermediating buffering that can effectively use the reference grounds of the circuit domains on either side of a buffer stage to generate one or more intermediated grounds for one or more signal buffers. For example, one of the reference grounds has a first amount of ground noise, the other of the reference grounds has a second amount of ground noise that is greater than or less than the first amount, and the intermediated grounds are generated to have respective amounts of ground noise that are between the first and second amounts. The ground intermediating buffer can perform signal buffering with respect to the intermediated ground(s), thereby reducing ground noise coupling across the circuit domains through both the signal and ground paths of the buffer stage.

  • Patent number: 10692698
    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.

  • Patent number: 10674581
    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). The CCM can be generated based on images captured within the area and/or a software simulation that approximates the contribution of light from the multichannel luminaires to the area. Once the CCM has been generated, the CCM can be used to compensate control signals to each multichannel luminaire in order to provide more accurate color rendering and uniform light distribution. Furthermore, feedback from embedded sensors (206) in the multichannel luminaires and/or sensors (116, 208, 210, 418) in the area can provide further basis for compensating control signals according to the qualities of the natural and artificial light entering the area, and the effects of different surfaces (128) on the light.

  • Patent number: 10671763
    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.
