  • Publication number: 20240159608
    Abstract: A power transmission gearbox system for a turbomachine is provided. the power transmission gearbox system includes a drivetrain having one or more rotating components. The system further includes at least one static component interfacing with the one or more rotating components. The system further includes a sensor disposed on the at least one static component and configured to provide data indicative of strain in the static component. The system further includes a controller communicatively coupled to the sensor. the controller includes a processor and a memory. the processor is configured to perform a plurality of operations. The plurality of operations includes monitoring the data indicative of strain in the static component from the sensor. The operations further include determining, at least partially based on the data indicative of the strain in the static component, a torque in the one or more rotating components of the drivetrain.

  • Patent number: 11978931
    Abstract: Molten carbonate fuel cell configurations are provided that allow for introduction of an anode input gas flow on a side of the fuel cell that is adjacent to the entry side for the cathode input gas flow while allowing the anode and cathode to operate under co-current flow and/or counter-current flow conditions. It has been discovered that improved flow properties can be achieved within the anode or cathode during co-current flow or counter-current flow operation by diverting the input flow for the anode or cathode into an extended edge seal region (in an extended edge seal chamber) adjacent to the active area of the anode or cathode, and then using a baffle to provide sufficient pressure drop for even flow distribution of the anode input flow across the anode or cathode input flow across the cathode.

  • Patent number: 11967009
    Abstract: The present disclosure includes a medical monitoring hub as the center of monitoring for a monitored patient. The hub is configured to receive and process a plurality of physiological parameters associated with the patient. The hub includes advanced analytical presentation views configured to provide timely, clinically-relevant, actionable information to care providers. In certain embodiments, the monitoring hub stores and is able to replay previously presented data reflective of the patient's condition.

  • Publication number: 20240106192
    Abstract: Disclosed herein are electronic devices that include arrays of dual function light transmit and receive pixels. The pixels of such arrays include a photodetector (PD) structure and a vertical-cavity, surface-emitting laser (VCSEL) diode, both formed in a common stack of epitaxial semiconductor layers. The pixels of the array may be configured by a controller or processor to function either as a light emitter by biasing the VCSEL diode, or as a light detector or receiver by a different bias applied to the PD structure, and this functionality may be altered in time. The array of dual function pixels may be positioned interior to an optical display of an electronic device, in some cases to provide depth sensing or autofocus. The array of pixels may be registered with a camera of an electronic device, such as to provide depth sensing or autofocus.

  • Patent number: 8499326
    Abstract: Described herein are techniques for facilitating the testing of cable television receivers during manufacturing and remanufacturing. More particularly, described herein techniques for simulating a conditional access module and/or cable television communication network/head-end for use during a testing process. The simulated conditional access module allows for the testing of a cable television receiver without the use of a head-end and/or fully functional conditional access module to verify all communication paths through the cable television receiver.

  • Publication number: 20130173332
    Abstract: Systems and methods for automatically and/or systematically include more data sources and/or more detailed data in the analysis, prediction, and model building. Process data may be employed to pinpoint the process parameter excursions and domain knowledge and/or expert systems may be automatically and/or systematically incorporated into the root cause analysis, the prediction and/or the model building to improve results and/or to reduce the reliance on inconsistent and expensive human experts.

  • Publication number: 20130080372
    Abstract: Computer-implemented methods and systems for tool health prediction for a tool having sub-systems and components are disclosed. The method includes providing parameter values from sensors to an expert system. The method also includes providing knowledge base data from a knowledge base to the expert system. The knowledge base includes at least one of tool history, part information, domain knowledge, and model history. The method also includes generating, using the expert system, at least one tool health prediction pertaining to tool maintenance. The prediction generation employs a set of prediction models that includes at least one prediction model. The prediction generation further employs at least the parameter values and the knowledge base data.

  • Publication number: 20130030760
    Abstract: Integrated yield/equipment data processing system for collecting and analyzing integrated tool-related data (cause data) and material-related data (effect data) pertaining to at least one material processing tool and at least one material is disclosed. In an embodiment, the tool-related data is correlated with the material-related data, and the correlated tool-related data and material-related data is employed by logic to perform at least one of root-cause analysis, prediction model building and tool control/optimization. By integrating cause-and-effect data in a single platform, the data necessary for performing, for example, automated problem detection (e.g., automated root cause analysis) and prediction, is readily available and correlated, which for example shortens the cycle time to detection and facilitates efficient and timely automated tool management and control.

  • Publication number: 20060240076
    Abstract: The present invention pertains to a method for preparing a hydrogel in dry conditions that contains high loading of the active ingredient, preferably flavor or fragrance molecules. The hydrogel compositions are initially in solid form and preferably extruded and sized to form the desired shape and size. The actual hydrogel is formed in-situ from the uptake of water that is present in the suspending medium. The hydrogels have the following properties: contain of up to 40% of active ingredient prior to the water uptake; retain color and particle identity in high moisture systems; and retain color and particle identity at elevated temperature.
