  • Publication number: 20030144844
    Abstract: An automatic speech recognizer only responsive to acoustic speech utterances is activated only in response to acoustic energy having a spectrum associated with the speech utterances and at least one facial characteristic associated with the speech utterances. In one embodiment, a speaker must be looking directly into a video camera and the voices and facial characteristics of plural speakers must be matched to enable activation of the automatic speech recognizer.

  • Patent number: 6578553
    Abstract: A method and a device are described for controlling an internal combustion engine, particularly an internal combustion engine that has a common-rail system. At least one pump delivers fuel into an accumulator. A pressure in the accumulator is detected. A distinction is made between at least one first operating state and at least one second operating state based on at least one speed signal and/or one load signal. At least one first pressure-control device is used to adjust the pressure in the at least one first operating state. At least one second pressure-control device is used to control the pressure in the at least one second operating state.

  • Publication number: 20030034010
    Abstract: In an internal combustion engine, in particular with direct injection, a first fuel pump delivers fuel from a fuel tank to a second fuel pump. This second fuel pump delivers the fuel to a fuel accumulation line. A metering unit is triggered by a control and/or regulating unit and meters the fuel quantity traveling into the inlet of the second fuel pump. In order to simplify the design of the engine and to reduce its cost, the invention proposes that during normal operation, the metering unit is closed when it is without power and that when the control and/or regulating unit is “dead”, the metering unit is without power and the fuel delivery to the metering unit is cut off.

  • Patent number: 6513037
    Abstract: A data base query submitted in natural speech normally requires a dialog with the data base system, which repeatedly prompts the user to submit further statements. From each speech utterance submitted by the user a plurality of sets of statements are derived. The statements in these sets are tested for consistency with stored statements determined previously and consistent new statements are stored and stored statements are corrected or verified. Moreover, the stored statements are basically used in each dialogue step in order to derive from these statements an optimum request for the user by the system. Preferably, the statements are also stored with probability values or reliability values, the corresponding values of new statements to be stored being derived from the reliabilities of the statements of the respective speech utterance and the corresponding consistent statements stored.

  • Patent number: 6196191
    Abstract: A fuel injection system for internal combustion engines, having a high-pressure fuel pump which fills a high-pressure collection chamber with high fuel pressure. Injection lines lead away from the high pressure collection chamber to the individual injection valves. A prefeed pump that feeds fuel from a tank via a low-pressure line system into a work chamber of the high-pressure pump, and at least one control valve controls the high-pressure pumping quantity of the high-pressure pump. Control valves are inserted into the low-pressure line system that adjust the fuel filling flow into the work chamber of the high-pressure pump to the fill volume actually required for operation.

  • Patent number: 6021761
    Abstract: The invention relates to a high-pressure pump for fuel delivery in fuel injection systems of internal combustion engines, which includes a tank, a pre-feed pump, and the high-pressure pump. The pre-feed pump aspirates a total fuel flow from the tank and this total fuel flow is divided into a lubricating flow, which is conveyed through the high-pressure pump for the purpose of lubrication, and a delivery flow, which is acted on with high pressure by the high-pressure pump and is delivered to a common distributor rail. The fuel injection system prevents damage that could occur during operation. Damage is prevented because the total fuel flow is conveyed through the high-pressure pump for the purpose of lubrication, wherein a metering unit for the total fuel flow is provided in the high-pressure pump or in a return and assures that only a predetermined delivery flow is acted on with high pressure in the high-pressure pump.

  • Patent number: 5987410
    Abstract: A method and device for recognizing speech that has a sequence of words each including one or more letters. The word and letters form a recognition data base. The method receives and recognizes the speech by preliminary modelling among various probably recognized sequences. The method selects one or more model sequences as result. In particular, the method allows in a model sequence of exclusively letters, various words as a subset. Such words are used to qualify one or more neighbouring or included letters in the sequence. An applicable model is a mixed information unit model.

  • Patent number: 5954407
    Abstract: A process and device for an open-loop control and a closed loop control of the brake system of a vehicle, wherein brake pedal actuation is measured by at least two, preferably diversitary, measuring devices, and the driver's braking command is independently obtained and further processed from at least two actuation signals. A third measuring device, measuring brake pedal actuation, is provided for locating errors. The control device effecting the open-loop control and the closed-loop control of the brake system comprises at least two microcomputers with the signals of the at least two measuring devices being supplied to both, while the signal of the monitoring device is only supplied to one microcomputer.

  • Patent number: 5897225
    Abstract: A watertight photographic single-use camera having a first and a second body shell that join together. The body shells comprise rigid polymer material and are adapted to receive a film transport device, a lens, a flash unit and a viewfinder. The first body shell forms the camera front section and the second body shell forms the camera rear section. A sealing means comprising an elastic polymer material is attached to an edge of at least one body shell that forms a joint and to at least one edge that forms a body opening. The elastic polymer material is attached by a multiple-component injection molding process and is connected to the body shell by chain looping (molecular entanglement) of the polymer material. As a result, the camera is dependably sealed against water and yet is inexpensive and simple to produce.

  • Patent number: 5884606
    Abstract: The invention relates to a system for generating high fuel pressure for a fuel injection system used in internal combustion engines in which via a low-pressure pump fuel aspirated from a fuel tank is delivered via a low pressure line and at least one valve to a high-pressure pump, and some of the fuel stream is diverted to the return loop from the low pressure line at or upstream of the high-pressure pump. In the low pressure line, an electrically controlled flow regulating valve is inserted between the low-pressure pump and the high-pressure pump. The flow regulating valve splits the fuel stream supplied. One portion is delivered to the high-pressure pump, and the remainder is relieved into the return loop. The flow regulating valve requires little space and only a few connections and is simple to manipulate.
