  • Patent number: 11974376
    Abstract: The invention relates to a monitoring system (13) for monitoring electrical devices (A, B, C, D, K) like luminaires. An assignments providing unit (7) provides assignments between the electrical devices and behavior classes defining expected behaviors, wherein a deviation determination unit (9) determines a deviation a) between a monitored behavior of an electrical device assigned to a behavior class and an expected behavior defined by a behavior class and/or b) between a monitored behavior of an electrical device and a monitored behavior of another electrical device, wherein an output unit (10) provides an output depending on the determined deviation. The deviation can be indicative of a commissioning error, i.e., for instance, of an assignment of an electrical device to a wrong room within a building. The monitoring system can therefore allow for an automatic detection of commissioning errors in a building which may have thousands of electrical devices.

  • Patent number: 11935730
    Abstract: Systems and methods for cleaning an edge ring pocket are described herein. One of the methods includes providing one or more process gases to a plasma chamber, supplying a low frequency (LF) radio frequency (RF) power to an edge ring that is located adjacent to a chuck of the plasma chamber. The LF RF power is supplied while the one or more process gases are supplied to the plasma chamber to maintain plasma within the plasma chamber. The supply of the LF RF power increases energy of plasma ions near the edge ring pocket to remove residue in the edge ring pocket. The LF RF power is supplied during the time period in which a substrate is not being processed within the plasma chamber.

  • Patent number: 11917740
    Abstract: Systems and methods are provided to transmit a data encoded power signal to addressable devices. A lighting controller sends the data encoded power waveform to a plurality of addressable lighting modules to power and control a behavior of the lighting modules. An inventory function causes the lighting controller to send, one by one, each of the possible unique addresses, or for a particular range of addresses, a command to turn ON lighting modules. The lighting controller monitors the current draw of the power supply or the data encoded power waveform and compares the monitored current with a threshold to determine whether the addressed lighting module responded to the command. The lighting controller provides the user, via a user interface, a list of the responding lighting modules based on the comparison.
