Abstract: A web-based interface enables medical personnel to remotely monitor medical devices. A monitoring system records operational data and alarms from the medical devices in a file. However, since network connections between the medical devices and the monitoring system are intermittent, the file does not contain a contiguous stream of data for each medical device. The file pauses recording during gaps in network connectivity. The system displays current data, as well as a list of alarms. If medical personnel wish to view more detail about an earlier time or one of the alarms, the system calculates where in the file the medical device data was recorded. This calculation accounts for the discontiguous nature of the data. The system uses times the network connection is made and broken to calculate an index into the file that corresponds to the time of the user-selected alarm.

An indication of whether the image is detected in the video is output based on the combined score.

Abstract: Embodiments herein describe an audio forwarding regularizer and an information bottleneck that are used when training a machine learning (ML) system. The audio forwarding regularizer receives audio training data and identifies visually irrelevant and relevant sounds in the training data. By controlling the information bottleneck, the audio forwarding regularizer forwards data to a generator that is primarily related to the visually irrelevant sounds, while filtering out the visually relevant sounds. The generator also receives data regarding visual objects from a visual encoder derived from visual training data. Thus, when being trained, the generator receives data regarding the visual objects and data regarding the visually irrelevant sounds (but little to no data regarding the visually relevant sounds). Thus, during an execution stage, the generator can generate sounds that are relevant to the visual objects while not adding visually irrelevant sounds to the videos.
