Abstract: A control circuit for at least two drivers is provided. Each of the two drivers is configured to switch on and off electrically driven switching elements that are electrically connected to each other. The control circuit includes a first parallel-to-serial-converter including a first parallel input port and a first serial output-port connectable to a first driver, a second parallel-to-serial-converter including a second parallel input port and a second serial output-port connectable to a second driver, and a processor unit configured to send a first data package stream to the first parallel input port, and send a second data package stream to the second parallel input port. Both the first data package stream and the second data package stream are configured to be converted to serial-data-streams at the first serial output-port and the second serial output-port, respectively. The serial data-streams are configured to control the at least two drivers.

Abstract: A control device for a conditioned space includes a first face and a second face. The first face is configured to be mounted on a surface at a height accessible by a user. The second face has a display. A first axis normal to the display is angularly offset by an angular amount from a second axis normal to the surface. The first axis normal to the display is substantially parallel with a line of sight associated with the user at an access distance from the control device.

Abstract: Systems and methods for locating building equipment in a building management system (BMS) are provided. An HVAC system includes an HVAC controller and an HVAC device. The HVAC device includes processing circuit including a memory and a processor. The processing circuit automatically determining a location of the HVAC device reporting the location of the HVAC device to the HVAC controller.

Abstract: Methods, apparatus and systems for detecting an arc during supplying a plasma process in a plasma chamber with a power are provided. An example plasma power supply includes: a DC source, an output signal generator, a first signal sequence measurement device for measuring a first signal sequence present between the DC source and the output signal generator, a second signal sequence measurement device for measuring a second signal sequence present at an output of the output signal generator, and a controller configured to generate a reference signal sequence based on one of the first and second signal sequences, to compare the reference signal sequence and the other of the first and second signal sequences that has not been used to determine the reference signal sequence, and to generate a detection signal if the reference signal sequence and the other of the first and second signal sequences cross.

Abstract: Systems and methods of monitoring a discharge in a plasma process are disclosed. The methods include supplying the plasma process with a periodic power supply signal, determining a first signal waveform in a first time interval within a first period of the power supply signal, determining a second signal waveform in a second time interval within a second period of the power supply signal, the second time interval being at a position within the second period corresponding to a position of the first time interval within the first period, comparing the second signal waveform with a reference signal waveform to obtain a first comparison result, determining that the first comparison result corresponds to a given first comparison result, and in response, time-shifting one of the second signal waveform and the reference signal waveform, and comparing the time-shifted signal waveform with the non-time-shifted signal waveform to obtain a second comparison result.
