Abstract: This disclosure describes techniques that enable a safety detection controller to analyze and infer a likelihood of a safety concern impacting a monitored individual at a real-time event. More specifically, a safety detection controller may receive sensor data from a monitored device associated with a particular individual. The sensor data may be captured from the environment that is proximate to the monitored device. The safety detection controller is further configured to analyze the sensor data to infer the identities of third-party individuals proximate to the monitored device and determine whether those individuals pose a safety concern to the monitored individual.

Abstract: For positron emission tomography (PET) detector gain stabilization despite temperature variation, an open loop gain control based on temperature establishes a baseline gain despite possible temperature variation. The baseline gain is then adjusted with a more sensitive closed-loop (e.g., peak tracking) approach for dealing with temperature. By combining both types of gain control to deal with temperature, the advantages of both are provided while avoiding disadvantages of either approach by itself.
