Abstract: An anomaly diagnosis system obtains a plurality of anomaly signals corresponding to a plurality of sensor signals of a physical system and segments one or more anomaly signals into a plurality of time segments. The system determines an anomaly score for each time segment based on anomaly values of the one or more anomaly signals during the time segment and identifies an anomaly time interval corresponding to at least one consecutive time segment within the plurality of time segments. The system clusters the plurality of anomaly signals within the anomaly time interval to identify an anomaly group of sensor signals associated with the anomaly time interval and determines an aggregate anomaly score for the anomaly group. The system generates a graphical user interface presenting a representation of the anomaly group of sensor signals and the aggregate anomaly scores and causes the graphical user interface to be displayed on a user device.

Abstract: Ground impedance may have adverse effects on the performance of RF circuits that employ shunt switches. The disclosed methods and devices address this issue. The methods and devices involve the use of resonance-canceling inductors to counteract the capacitive reactance caused by parasitic capacitances and/or decoupling capacitors utilized in such systems. Solutions that incorporate series resistors to distribute the resonance across the frequency band of operation are also described. Additionally, devices that employ digitally tuned capacitors to shift the resonance frequency outside the operational band are presented.

Abstract: A remote plasma source (RPS) may include a toroidal chamber shaped to promote diffusion, reduce fluid velocity, and prolong fluid residence time in the RPS. A toroidal chamber may include an inlet, an outlet, an input leg, an output leg, and two interstitial legs connecting the input and output legs. A reference plane may bisect the toroidal chamber, the inlet, the outlet, and the four legs, wherein the inlet is substantially perpendicular to the reference plane and thereby configured to direct a fluid into the toroidal chamber substantially perpendicularly to the reference plane. A second inlet may be arranged in an opposing direction to the first inlet, either at the same corner of the input leg or at an opposing corner of the input leg.

Abstract: Ground impedance may have adverse effects on the performance of RF circuits that employ shunt switches. The disclosed methods and devices address this issue. The methods and devices involve the use of a switch to remove a decoupling capacitor from an RF circuit on an integrated circuit (IC) pin where the storage cap is connected; or modifying the turn-on threshold of an electrostatic discharge protection device (ESD) on the IC pin with the storage cap present to reduce susceptibility to turning on the ESD with the RF signal; or de-Qing the analog and digital core capacitances to minimize their contribution to resonance; or a combination thereof.

Abstract: A computer system for managing a machine learning model that detects potential anomalies in the operation of a complex system is disclosed. In some embodiments, the computer system is programmed to receive sensor signal data originally produced by sensors of the complex system. The sensor signal data can include values for multiple sensor signals at multiple resolutions. The computer system is programmed to train, from given sensor signal data, the machine learning model that comprises one or more transformers, each transformer capturing a set of relationships between signals in a predetermined group of signals. During training, the computer system is programmed to also establish an expected range for an indicator of the relationship. The computer system is programmed to then execute the machine learning model on new sensor signal data and take remedial steps when any computed indicator falls outside the expected range, indicating a potential anomaly in the operation of the complex system.

According to one aspect, the RF amplifier is part of switchable RF paths that include at least one path with one or more attenuators that can be used during normal operation to define different modes of operation of the at least one path. An RF level detector monitors a level of an RF signal during operation of any one of the switchable RF paths and forces the RF signal through the at least one path with one or more attenuators while controlling the attenuators to provide an attenuation of the RF signal according to a desired level of protection at an input and/or output of the RF amplifier.
