  • Publication number: 20240019410
    Abstract: First sensor data indicative of a first mass flow rate of a first gas flowing to a vaporization chamber is received. The vaporization chamber includes a compound and is to transition the compound into a gaseous state. Second sensor data indicative of a second mass flow rate of a second gas including the compound and the first gas flowing out of the vaporization chamber is received. Third sensor data indicative of a third mass flow rate of the compound into the vaporization chamber is received. The first sensor data, the second sensor data, and the third sensor data is processed using a trained machine learning model to determine an estimated concentration of the compound within the second gas. At least one of a) modifying a flow rate of the first gas or b) providing the predicted concentration for display by a graphical user interface (GUI) is performed.

  • Patent number: 11808746
    Abstract: A concentration sensor assembly can include a vaporization chamber having a compound. The concentration sensor assembly may include a first flow path coupled to the vaporization chamber. The first flow path may direct a first gas to the vaporization chamber. A second flow path can direct a second gas out of the vaporization chamber. The second gas can include the compound and the first gas. A first sensor is disposed along the first flow path. The first sensor measures first data indicative of a first mass flow rate of the first gas. A second sensor is disposed along the second flow path. The second sensor measure second data indicative of a second mass flow rate of the second gas. A computing device may determine a concentration of the vaporizable substance within the second gas based on the first data and the second data.

  • Publication number: 20230089982
    Abstract: An electronic device manufacturing system includes a transfer chamber, a tool station situated within the transfer chamber, a process chamber coupled to the transfer chamber, and a transfer chamber robot. The transfer chamber robot is configured to transfer substrates to and from the process chamber. The transfer chamber robot is further configured to be coupled to a sensor tool comprising one or more sensors configured to take measurements inside the process chamber. The sensor tool is retrievable from the tool station by an end effector of the transfer chamber robot.

  • Publication number: 20210365919
    Abstract: Various methods, apparatuses/systems, and media for implementing a payment optimizer application module are disclosed. A supplier system accepts a predefined fixed net payment term for all participating buyers on a network. A processor determines weighted average cost of capital (WACC) data of buyer key data points from buyer audited statements data corresponding to a payment file data and WACC data of supplier key data points from supplier audited statements data corresponding to the payment file data. The processor also determines an optimal disbursement date of payment over the predefined fixed net payment term based on the WACC data; applies the stored set of payment rules to determine an optimal payment method corresponding to the WACC data; and automatically executes disbursement of a payment to the supplier in accordance with the optimal disbursement date based on the optimal payment method.
