Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

Abstract: A deposition system provides a feature that may reduce costs of the sputtering process by increasing a target change interval. The deposition system provides an array of magnet members which generate a magnetic field and redirect the magnetic field based on target thickness measurement data. To adjust or redirect the magnetic field, at least one of the magnet members in the array tilts to focus on an area of the target where more target material remains than other areas. As a result, more ion, e.g., argon ion bombardment occurs on the area, creating more uniform erosion on the target surface.

Abstract: The present disclosure provides a self-adaptive test method for an intelligent prediction algorithm of analog measured values. Firstly, an event recording sequence, an analog measurement point ID and an analog measurement point alarm value are read from a time sequence event record table, an analog measurement point table and an alarm threshold table. Next, operation records of a normal operation state of a unit within a statistical cycle are acquired to form historical statistics of measured values of the analog measurement point based on switching value signals. Then, simulated measured values of the analog measurement point with time scales are calculated based on the historical statistics, the analog measurement point alarm value and an analog measurement point current measured value. Finally, sensitivity is calculated; and an alarm is sent to remind a technician to adjust the algorithm when the sensitivity is greater than a threshold.
