A method for determining a burst pipe that requires immediate feeding-valve closing using acoustic and / or vibration sensors coupled to the pipe lor detecting signals, a microprocessor for analyzing signals from said sensors in real-time, a memory coupled to said microprocessor for storing data, including digital signatures acoustic and / or vibration signatures, as well as an actuator electrically coupled to said microprocessor and mechanically coupled to said feeding-valve. When the sensor signals match stored leak-signatures or when a persistent sensor signal produces no match, the system of the present invention initiates a valve closing. To improve detection, signals from other sensors, i.e. water sensors, smoke detectors, heat sensors or acoustic / vibration sensors mounted on other pipes are also used.

The system and method provides robust and reliable event scoring and reporting, while also optimizing data transmission bandwidth. The system includes onboard vehicular driving event detectors that record data related to detected driving events, selectively store or transfer data related to said detected driving events. If elected, the onboard vehicular system will score a detected driving event, compare the local score to historical values previously stored within the onboard system, and upload selective data or data types to a remote server or user if the system concludes that a serious driving event has occurred. Importantly, the onboard event scoring system, if enabled, will continuously evolve and improve in its reliability by being periodically re-calibrated the ongoing reliability results of manual human review of automated predictive event reports. The system may further respond to independent user requests by transferring select data to said user at a variety of locations and formats.

An apparatus and method for improving the communication capabilities of computer systems is disclosed. The most preferred embodiments of the present invention use a series of data buffers and data registers to process an incoming high speed data signal. By using the buffers and registers, the incoming signal can be reformatted and manipulated at a much lower frequency than the original transmission frequency. The deserializer of the present invention also samples a greater portion of the incoming data signal than usual to further increase reliability. These various features of the invention provide for a more stable and reliable communication link and will also provide a less expensive solution for serialization / deserialization.

In a method for the combustion of a fuel, a fuel or a premixed combustible mixture is introduced into a combustion space as a combustible fluid open jet. The velocity of the open jet is selected in such a way that it is impossible for a stable flame front to form, i.e. is in any event greater than the flame front velocity, and that, on account of a jet pump effect, flue gas is mixed into the combustible fluid jet from the combustion chamber in a jet-induced recirculation internally within the combustion chamber. The admixed flue gas dilutes and heats the combustible fluid. The heating causes the spontaneous ignition temperature to be exceeded, and a low-pollutant volumetric flame is formed in a highly dilute atmosphere.
