摘要： A method for managing alarm events in a physiological monitoring system is described. The method includes validating the accuracy of alarm events by checking if the alarm events are noise events. The method further includes identifying a pattern in alarm sequence or an alarm rate of at least one alarm type associated with the alarm events. The alarm rate is the frequency of the occurrence of alarm events for the particular alarm type. Based on the identified pattern in the alarm sequence and the alarm rate and patient data, an alarm level associated with the alarm type is adjusted. The hospital staff is notified depending on the criticality of the adjusted alarm level. Further, the alarm signals are suppressed when either a patient intervention or a pause signal is detected by the physiological monitoring system.

摘要： A system for generating a threat alert in an infrastructure component is provided. The system includes multiple acoustic sensors disposed in a protected zone around the infrastructure component, wherein each of the sensors is configured to detect a signal corresponding to an outcome that causes damage to the infrastructure component. The system also includes a processing circuitry coupled to each of the multiple acoustic sensors. The processing circuitry includes at least one analog-to-digital converter configured to digitize the signal. The processing circuitry also includes a digital signal processor configured to process the acoustic signal in a sequential routine. The sequential routine includes a noise filtering routine configured to filter background noise from the acoustic signal and generate a filtered signal. The sequential routine also includes a source identification routine configured to identify a source generating the acoustic signal based upon the filtered signal. The sequential routine further includes a threat analysis routine configured to detect a threat based upon the source identified and generate a threat level signal. The system also includes a remote monitoring center that receives the threat level signals from the processing circuitry and transmit an alert message to a concerned authority.
