Multifunctional telemetry alert safety system (MTASS)

A personnel accountability and situational awareness monitoring communications system for emergency personnel that comprises wireless network-adaptable monitoring devices, peripherals and base station console software for telemetry monitoring of real-time information at a plurality of personnel accountability and situational awareness parameters of critical data about the safety, health and whereabouts of first responders deployed in typically hazardous environments. Exterior incident command, including fire, rescue, safety and other emergency agencies achieve real-time command view and control over a variety of personnel accountability and safety parameters during emergency response activities of personnel wearing the system of the present invention portable device while operating within the wireless network of an emergency incident scene. Configured to be carried by emergency services personnel while deployed on scene, the portable device is a multi-functional sensing and communicating integration of accountability and situational awareness technologies consolidated into one portable, telemetry device. The portable device's multifunctional integrated technology includes the monitoring, telemetry and alert notification of accountability identification, location, assignment notification, vital signs, ambient vicinity temperature, SCBA status, combustible gas sensing, video streaming, “evacuation” recall signaling, signal tracking and multi-alarm signaling if the wearer has either low remaining air pressure/time, impending thermal breakthrough, low battery power, exceeds the safety threshold for safe heart rate or external body temperature readings, or becomes motionless for a predetermined time period.

System, method and terminal processing apparatus for optical fiber transmission

Disclosed by the present invention is a system and method for optical fiber transmission. The switching portion of the present invention adopts the single-layered integrated switching technology so as to ensure a relatively simple and easy maintenance compared with the switching in a traditional communication network where said switching is made in the service network layer and the bearer network layer, respectively. Moreover, the present invention implements data transmission via optical fiber throughout the entire telecommunication system such that demands for bandwidth resources are satisfied during the whole data transmission process and the QoS (Quality of Service) of different services as well as rapid and un-blocking switching of the services are ensured in the telecommunication system. Therefore, the present invention can implement on-demand allocation of bandwidth resources, enhancing the flexibility in network resource management while a subscriber can apply for bandwidth resources based on its demand, which satisfies the individual needs of the user.
