  • Patent number: 10810540
    Abstract: An inventory location such as a shelf may be used to stow different types of items. Interactions may take place, such as the pick or place of one or more items from the inventory location. Weight data may be acquired from weight sensors coupled to the shelf. A measured change in weight is used to determine a first group of hypotheses. Each of the hypotheses may be descriptive of a different permutation of products being added to or removed from the shelf that could account for the measured change in weight. The weight data is also processed to determine a weight distribution of the items on the shelf. Information about the weight distribution may be used to select a subset of the first group of hypotheses. The subset may be used to determine what items were interacted with, quantity involved, and so forth.

  • Patent number: 10753787
    Abstract: Described are systems for processing sensor data associated with an inventory location for the purpose of identifying stable and unstable states in the sensor data. The stable and unstable states can be determined by fitting a line or curve to a portion of the sensor data occurring during a window of time and calculating a corresponding slope value of the line or curve. By comparing the slope value of the line or curve to a threshold value, stable and unstable states can be determined for the sensor data. Once stable states have been identified, a change in sensor data can be determined and used to identify a change in quantity of items at the inventory location.

  • Patent number: 10735538
    Abstract: An approach is provided in which a system determines that an amount of times that a set of data was requested by clients from a backend service exceeds a threshold and, in turn, stores the set of data in a local storage area. When the system receives a new request from a client and determines that the new request is requesting the set of data from the backend service, the system retrieves the set of data from the local storage area and provides the retrieved set of data to the client to fulfill the new request.

  • Publication number: 20190299356
    Abstract: Data received from an in-situ monitoring system includes, for each scan of a sensor, a plurality of measured signal values for a plurality of different locations on a layer. A thickness of a polishing pad is determined based on the data from the in-situ monitoring system. For each scan, a portion of the measured signal values are adjusted based on the thickness of the polishing pad. For each scan of the plurality of scans and each location of the plurality of different locations, a value is generated representing a thickness of the layer at the location. This includes processing the adjusted signal values using one or more processors configured by machine learning. A polishing endpoint is detected or a polishing parameter is modified based on the values representing the thicknesses at the plurality of different locations.

  • Patent number: 10374506
    Abstract: An adaptive control method for zero voltage switching belongs to the field of integrated circuit. In the present invention, the difference between the turn-on time of the power tube and the time of the lowest drain voltage of the power tube in the switching cycle is quantified by the reversible counter, and the quantized result is transmitted to the next switching cycle to adjust the turn-on time of the power tube through the final count result of the reversible counter, so that the power tube after being adjusted can be turned on when the drain voltage of the power tube is the lowest, thus reducing the switching loss. The present invention can adaptively turn on the power tube when the drain voltage of the power tube reaches minimum, thus, realizing the zero-voltage switching, reducing the switching loss of the switching power supply, widening the application range.
