Abstract: Systems and methods for using a transformer to achieve uniformity in processing a substrate are described. One of the systems includes a primary winding having a first end and a second end. The first end is coupled to an output of an impedance matching circuit and the second end is coupled to a capacitor. The system further includes a secondary winding associated with the primary winding and coupled to a first end and a second end of a transformer coupled plasma (TCP) coil of a plasma chamber. The primary winding receives a modified radio frequency (RF) signal from the impedance matching circuit to generate a magnetic flux to induce a voltage in the secondary winding. An RF signal generated by the voltage is transferred from the secondary winding to the TCP coil.

Title: Motor assembly for driving a pump or rotary device with a low inductance resistor for a matrix converter
Inventor: WILLIAMS DEAN
IPC: H01C3/02
Filed: 2021-01-20
Abstract: A resistor assembly for a motor drive circuit for an electric motor assembly can have a generally circular shape. The resistor assembly includes a resistor with input and output connectors and a pair of conductor elements extending from the input and output connectors. The pair of conductor elements extend adjacent each other along a curved serpentine path so the resistor has a generally circular outer perimeter and a generally circular inner perimeter. The curved serpentine path of the pair of conductor elements allows current to flow through the pair of conductor elements so that magnetic fields generated by the current flow through the pair of conductor elements cancel each other, thereby providing the resistor with low inductance.

Filed: 2021-05-14
Abstract: An imaging system includes multiple LED modules, a single image sensor, a controller, a processing unit and a depth map generator. Each LED module has a distinct angular emission profile and emits light having a distinct wavelength range.

The controller controls the LED modules to turn on and off such that only one LED module emits light at a time. The processing unit processes the image sensor output to identify an intensity profile for the reflected light from each of the LED modules. The depth map generator determines an angular position of the object based at least on the intensity profile for the reflected light from each of the LED modules.

Inventor: CHEN YONGJUN
IPC: G06N3/08
Filed: 2021-07-29
Abstract: Embodiments described herein provide an attentive network framework that models dynamic attributes with item and feature interactions. Specifically, the attentive network framework first encodes basket item sequences and dynamic attribute sequences with time-aware padding and time/month encoding to capture the seasonal patterns (e.g. in app recommendation, outdoor activities apps are more suitable for summer time while indoor activity apps are better for winter). Then the attentive network framework applies time-level attention modules on basket items' sequences and dynamic user attributes' sequences to capture basket items to basket items and attributes to attributes temporal sequential patterns. After that, an intra-basket attentive module is used on items in each basket to capture the correlation information among items.
