  • Patent number: 11967062
    Abstract: An automatic measuring system containing configurable integrated circuits is able to process information via captured images. The automatic measuring system includes a metering instrument, a camera, a recognition module, and a localization module. The metering instrument has at least one display for visually displaying a number and measures the amount of measurable substance or resources (i.e., electricity and water) consumed. The camera captures an image of the number representing at least a portion the amount of measurable substance. The recognition module is operable to generate a value in response to the image and the coordinates wherein the coordinates are used to decode the image via restoring captured image to the original readout counter value. The localization module is removably or remotely coupled to the camera and operable to generate the coordinates in accordance with the image captured by the camera.

  • Publication number: 20230406789
    Abstract: Selective removal of non-aromatic hydrocarbons from a xylene isomerization process for para-xylene production is accomplished using a membrane unit positioned within a xylene recovery loop. The membrane unit may include a one-stage or multi-stage (e.g., two-stage) membrane system and may be configured to separate a membrane unit product stream from a non-aromatics rich stream, which can be removed from the xylene recovery loop. The membrane unit may have a xylene permeance of about 60 gm/m2/hr/psi and a xylene to non-aromatic permeance ratio of about 15.

  • Publication number: 20220071216
    Abstract: The disinfectant-dosing microgel is formed from a mixture of a sol and a solution of a disinfecting and deodorizing agent. In use, the sol phase is transformed, by various conditions, into an active microgel. The disinfectant-dosing microgel is applied to the waste, such as by spraying, mixture therewith or the like. The combination of the sol and the solution of the disinfecting and deodorizing agent or, alternatively, the combination of the polymer and the solution of the disinfecting and deodorizing agent, is triggered to transform from the sol phase into the active microgel for long-term disinfection and deodorization of the waste by the temperature, pH, and/or salt concentration of the waste. The transformation to the active microgel for long-term disinfection and deodorization of the waste can also be initiated by adding chemical substances to alter the pH or promote gelation, either before, during or after application to the waste.

  • Publication number: 20070226128
    Abstract: Methods, apparatus, and articles of manufacture for capturing commercial loan application data and assigning a commercial loan request are disclosed herein. Embodiments of the invention provide mechanisms for capturing commercial loan application data, assigning a commercial loan request, monitoring an approval process, and administering association of accounts with approved requests via a series of user interface displays communicated to a user via a network communication link. In addition, the network environment of the invention provides for the storage of data in a relational database management system that enables previously entered data to populate data fields of applets within the user interface displays without the necessity to re-enter the data. Moreover, the status of the review process may be monitored to more quickly respond to requests for such information by the customer.
