  • Patent number: 7980126
    Abstract: A method is provided for operating a hot-film air-mass sensor, which can be used especially for measuring air mass flows in the intake tract of an internal combustion engine. The hot-film air-mass sensor has a sensor chip having a sensor frame and a sensor diaphragm having at least one heating element and at least two temperature sensors, a chip carrier for holding the sensor chip and at least one additional heating element. The sensor chip is able to be heated up using the at least one additional heating element. Immediately after shutting down the internal combustion engine, the at least one heating element of the sensor diaphragm is switched off, or is switched to a lower heating power. Furthermore, the at least one additional heating element is switched on for a specified postheating phase. The provided method is particularly suitable for avoiding oil contamination of the hot-film air-mass sensor.

  • Patent number: 7980505
    Abstract: In a method for calculating the diameter of a continuous-material reel on a roller, with which the roller is mounted on a swivel arm that is swivelable about a swiveling axis; the roller rotates at a changeable winding speed, and the continuous material is unwound from the roller and directed to a continuous-material machine, or it is removed from a continuous-material machine and wound onto the roller, the winding speed is set as a function of the web-conveyance speed, and the diameter of the continuous-material reel is calculated in a reel-control system; the winding speed is changed when the swivel arm on which the roller is mounted is swiveled about its swiveling axis during the winding motion; a correction value for correcting the change in winding speed is incorporated in the calculation of the diameter of the continuous-material reel, the correction value being determined within the reel-control system, and a related reel-control system is provided.

  • Patent number: 7982333
    Abstract: A voltage regulator having overvoltage protection which is situated in a vehicle electrical system between the generator that is situated in a first voltage level and a battery that is situated in a second voltage level. A generator is used as a generator whose control voltage is freely selectable within specifiable limits. The voltage regulator, which is embodied as an in-phase regulator, makes available a regulated voltage on the output side, which is used for supplying the usual vehicle electrical system users as well as for charging the battery. The in-phase regulator is furnished with an electronics system or an intelligence which includes a microprocessor and which evaluates supplied data with regard to voltages, currents or load breakings and which specifies response criteria, and, upon the reaching of certain response criteria, initiates the measures which then become necessary.

  • Patent number: 7983834
    Abstract: A method and a device for operating an internal combustion engine having at least one mass flow line and a cooling device for cooling the mass flow in the mass flow line, as well as a bypass, having a bypass valve, that bypasses the cooling device. When the bypass valve is opened, the mass flow is conducted at least partly through the bypass. When the bypass valve is closed, the mass flow is conducted through the cooling device. Downstream from the cooling device and from the bypass in the mass flow line, a temperature of the mass flow in the mass flow line is determined. In at least one operating state of the internal combustion engine, a first temporal temperature gradient is determined with closed bypass valve. In the at least one operating state of the internal combustion engine, a second temporal temperature gradient is determined with closed position of the bypass valve.

  • Publication number: 20110169370
    Abstract: The invention relates to a six-pole DC machine, particularly a DC motor for use in a motor vehicle, having a stator (16) excited preferably by a permanent magnet and a rotor (20) which is rotatably supported in a pole housing (12) and which has a wave winding (23) and a commutator (24), and having a brush carrier (28) for holding the brushes (26) and preferably additional components (30, 31; 32). In contrast to a full equipping, the brush arrangement has less than six brushes (26), which are arranged on the circumference of the commutator (24) at an angular distance of approximately 60° to each other. Thus, the ripple of the rotor current, the torque oscillations, and the noise emission are clearly reduced and free space is created on the brush carrier for accommodating suppressor components (30, 31; 32).
