A statistical multiplexer is provided with a series of encoders that encode media streams at different bitrates to reduce jitter. The encoded media streams are transmitted to a multiplexer over a network and experience jitter that is reduced by a de-jitter arrangement.

One high-voltage insulator includes a first piece formed from a first material, a second piece formed from a second material, and an interface section where the first piece contacts with and forms a seal with the second piece. The interface includes a first groove located that accommodates a first gasket, sets of matching threads on the first and second pieces. The interface section further accommodates a second gasket. In this multi-piece high-voltage insulator, the first material can have a first set of flexural, heat resistance, and electrical standoff characteristics suitable for a first environment, and the second material can have a second set of flexural, heat resistance and electrical standoff characteristics suitable for a second environment. |

Determining engagement level of an individual during communication
A plurality of instances of a patient's health condition are received as patient health information from a plurality of sources. Ground-truth health conditions of the patient are generated based on the patient health information and expert review of the patient's level of engagement for each instance of provider assessment. A regression model predicting a probability of patient engagement level with a provider is generated, based on the instances of patient condition assessment and the engagement level expert review associated with each instance. A current set of patient information and natural language processing results of a dialog between the patient and a provider performing a condition assessment of the patient, are received. The current patient information and the dialog are applied to the regression model, determining a probability of patient engagement level. An indicator of the patient engagement level is sent to the provider's computing device. |

Methods and apparatus to capture patient vitals in real time during an imaging procedure
Apparatus, systems, and methods to capture and combine patient vitals and image data are disclosed. An example apparatus includes an imaging device to capture imaging data of a patient; a patient monitor to capture non-imaging data of the patient; and a communication interface between the imaging device and the patient monitor to route the non-imaging data to the imaging device. The example imaging device is to combine the non-imaging data with the imaging data to form a combined data set to be processed to determine a clinical outcome. |

Method of connecting a user device anonymously to a remote operator
A method of connecting a user device anonymously to a remote operator, via an intermediate anonymizing server is described. In this way, a remote operator may control the device, without the remote operator knowing the identity of the owner or of user of the device. A remote operator might provide medical support or entertainment. The user of the device is provided with a connection key, which is then further given by the user to a desired remote operator. Both the user and the remote operator provide the anonymizing server with the connection key. The anonymizing server opens a chat room uniquely associated with the connection key. Electronic connectivity is provided by forwarding messages between the user device and the remote operator through the chat room. No other access to the chat room is permitted. The anonymizing server does not store the connection key. No user application is required. |

Information processing apparatus, information processing system, storage medium, and information processing method
An information processing apparatus includes a controller. The controller obtains information about a designated area and information about a medical service target. The controller creates, in accordance with the population distribution in the designated area, a dispatch schedule for dispatching a medical service vehicle capable of dealing with the medical service target to the designated area. |

Methods for surgical guideline indicator mapping to facilitate automated medical bill adjudication and devices thereof
Systems and methods are provided for automating the process of automatically determining appropriateness of surgical team services performed during a medical procedure. Clinical resource data with known surgical guideline indicator (SGIs) may be us used to generate and store a mapping of medical procedure codes to indications of the appropriateness of surgical team services corresponding to the medical procedure codes. A medical bill associated with an insurance claim may be analyzed to extract a medical procedure code corresponding to a surgical procedure, and an automated adjudication recommendation for the medical bill may be made based on the mapping between medical procedure codes and SGIs. |

Computer vision technologies for rapid detection
A computer-implemented method includes preprocessing a variable dimension medical image, identifying one or more areas of interest in the medical image; and analyzing the one or more areas of interest using a deep learning model. A computing system includes one or more processors; and one or more memories storing instructions that, when executed by the one or more processors, cause the computing system to preprocess a variable dimension medical image, identify one or more areas of interest in the medical image; and analyze the one or more areas of interest using a deep learning model. A non-transitory computer readable medium contains program instructions that when executed, cause a computer to preprocess a variable dimension medical image, identify one or more areas of interest in the medical image, and analyze the one or more areas of interest using a deep learning model. |

Dose volume histogram and dose distribution based autoplanning
A method and system for generating a voxel-based quadratic penalty model for automatic intensity modulated radiation therapy (IMRT) treatment planning are disclosed herein. A computing system generates an initial assignment of threshold values to a penalty function for IMRT treatment planning. The computing system receives an update to a dose value associated with the IMRT treatment planning. The computing system dynamically updates the threshold values based on the updated dose value. The computing system continues to iterate the threshold values based on further updated dose values. |

Systems and methods for creating and selecting models for predicting medical conditions
Computer implemented methods are disclosed. The methods may include receiving historical data comprising at least one of provider data and patient data, and processing, using a processor, the historical data to identify one or more patterns. The method also may include generating one or more decision models from the historical data and the decision patterns, and providing one or more recommendations based on the one or more decision models. |
