Process based antenna configuration
Techniques for process based antenna configuration are described, and may be implemented via a wireless device to identify different usage scenarios and to adapt antenna configurations to optimize wireless performance based on the scenarios. For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios. The obstruction states are then correlated to antenna positions in the wireless device to prioritize (e.g., activate) antennas that are relatively unobstructed, such as by activating unobstructed antennas and/or deactivating obstructed antennas. Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process. |

Token check offline
Embodiments are directed to a method comprising, obtaining, by a first device, a first token, the first token associated with an amount of funds and a funds availability starting date. After the first token is obtained by the first device, the first device generates a second token linked to the first token and second token generation data. The second token generation data may include evidence that the second token was generated by the first device, and not another device. The second token generation data could be a first device identifier and the second token generation details, or could be a hashed value of the first device identifier and the second token generation details. The method also includes provisioning, by the first device, the second token and the second token generation data to the second device. |

Managing process analytics across process components
Embodiments of the present invention are directed to managing process analytics across process components. In some embodiments, an indication of a state of a process instance associated with a process is determined by querying a process engine. In accordance with the indication of the state of the process instance, an augmented process model is used to search machine data for data corresponding with at least one component of the process. The data corresponding with the at least one component of the process is associated with a process instance identifier that uniquely identifies the process instance. Thereafter, the data along with the process instance identifier is provided to the process engine to update the state of the process instance. |

Dynamic prediction of risk levels for manufacturing operations through leading risk indicators: dynamic risk sloping trend method and system
The invention provides a dynamic risk analyzer (DRA) that periodically assesses real-time or historic process data, or both, associated with an operations site, such as a manufacturing, production, or processing facility, including a plant's operations, and identifies hidden near-misses of such operation, when in real time the process data appears otherwise normal. DRA assesses the process data in a manner that enables operating personnel including management at a facility to have a comprehensive understanding of the risk status and changes in both alarm and non-alarm based process variables. The hidden process near-miss data may be analyzed alone or in combination with other process data and/or data resulting from prior near-miss situations to permit strategic action to be taken to reduce or avert the occurrence of adverse incidents or catastrophic failure of a facility operation. |
