Abstract: A system for controlling of wafer bow in plasma processing stations is described. The system includes a circuit that provides a low frequency RF signal and another circuit that provides a high frequency RF signal. The system includes an output circuit and the stations. The output circuit combines the low frequency RF signal and the high frequency RF signal to generate a plurality of combined RF signals for the stations. Amount of low frequency power delivered to one of the stations depends on wafer bow, such as non-flatness of a wafer. A bowed wafer decreases low frequency power delivered to the station in a multi-station chamber with a common RF source. A shunt inductor is coupled in parallel to each of the stations to increase an amount of current to the station with a bowed wafer. Hence, station power becomes less sensitive to wafer bow to minimize wafer bowing.

Abstract: Methods and systems are described for operating an imaging sensor, the imaging sensor including a multi-dimensional sensor. An electronic processor receives an output from the multi-dimensional sensor and transitions the imaging sensor from the low-power state into a ready state in response to a determination by the electronic processor, based on the output from the multi-dimensional sensor, that a first state transition criteria is satisfied and transitions the imaging sensor from the ready state into an armed state in response to a determination that a second state transition criteria is satisfied. In some implementations, the electronic processor operates the imaging sensor to capture image data only when operating in the armed state and prevents the imaging system from transitioning from the low-power state directly into the armed state.

Abstract: Methods and systems are described for operating an intra-oral imaging sensor that includes a housing, an image sensing component at least partially housed within the housing, and a temperature sensor. An output of the temperature indicative of a sensed temperature is received and evaluated to determine whether the intra-oral imaging sensor is positioned in the mouth of the patient. The determination of whether the temperature sensor may be based on one or more determined conditions including whether a current temperature exceeds a threshold, whether a first derivative of the sensed temperature exceeds a rate-of-change threshold, and whether a second derivative of the sensed temperature exceeds a temperature acceleration threshold. In some implementations, the operation of the intra-oral imaging sensor is automatically adjusted in response to a determination that the sensor has been placed inside the mouth of a patient.
