  • Patent number: 9508972
    Abstract: The invention relates to a venting device (1) for an electrochemical battery (90). The venting device comprises at least one inlet opening (2) for receiving gases venting from the battery (90), at least one outlet opening (3) for venting the gases received from the battery (90), and at least one flame arrester element (4). The inlet opening (2) is in communication with the outlet opening (3) via the flame arrester element (4). An explosion chamber (5, 6) is located within the venting device (1) on the side of the flame arrester element (4) which is directed to the outlet opening (3). The explosion chamber (5, 6) is arranged for developing and temporarily storing an explosive mixture of the gases received from the battery (90) and oxygen from the ambient air, which explodes in case a flame occurs within the explosion chamber (5, 6), thereby blowing off the flame.

  • Patent number: 8694448
    Abstract: A method and apparatus for providing an adaptive parser are disclosed. For example, the method receives a configuration for a router, and parses a command from the configuration. The method determines whether there is an existing entry for the command in a model of a configuration language, wherein the model of the configuration language is used to record a syntactic structure of each command in the configuration language and its relationship to other commands. The method creates a new entry for the command in the model of the configuration language, if there is no existing entry for the command; and uses the model to update the parser.

  • Publication number: 20060136162
    Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to a volume of a multi-dimensional, multi-scale model. A first predicted value of seismic response for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. A synthetic trace is generated and iteratively compared to the corresponding trace obtained from one or more sets of actual seismic data to determine a difference while consistency is maintained between the types, scales and dimensions of values and data.

  • Publication number: 20050192994
    Abstract: An improved data compression method and apparatus is provided, particularly with regard to the compression of data in tabular form such as database records. The present invention achieves improved compression ratios by utilizing metadata to transform the data in a manner that optimizes known compression techniques. In one embodiment of the invention, a schema is generated which is utilized to reorder and partition the data into low entropy and high entropy portions which are separately compressed by conventional compression methods. The high entropy portion is further reordered and partitioned to take advantage of row and column dependencies in the data. The present invention enables not only much greater compression ratios but increased speed than is achieved by compressing the untransformed data.

  • Publication number: 20050119827
    Abstract: A combined GPS/Bluetooth module for a vehicle may be mounted on, e.g., the rear view mirror housing to receive position information from GPS and other information (such as tire pressure and other vehicle diagnostic information) over a Bluetooth link. In turn, the module can transmit over Bluetooth both the GPS data and the diagnostic information to the vehicle onboard computer or to a PDA, wireless telephone, or other display-bearing device in the vehicle for display thereof.

  • Publication number: 20050065449
    Abstract: This invention relates to non-contact monitoring devices, and more particularly, non-contact respiration monitoring devices. According to the invention there is provided a monitoring device having a body defining an air monitoring channel between an air inlet and an air outlet. Disposed in monitoring channel is a respiration detection means, such as a flap-valve, which operates with associated logic circuitry to report the presence or absence of respiration via visual and audible displays. The device may be configured to attached, or be integrally connected to, the air input orifice of an air filter canister of a gas mask or the like. Alternatively, the device may be associated with the air output orifices or valves of a gas mask or the like.
