  • Publication number: 20090046034
    Abstract: The invention relates to a digital information system for displaying information on at least one display means with the aid of at least one television set or camera. The exposures are presented at places accessible to and frequented by a general public. The information system includes external information mediators and information is controlled dynamically through the medium of a communication interface and through the medium of an exposure handler in a central computer. The inventive system also includes a communication interface against an elective number of cinema computers having connected television or camera computers which control television sets or cameras for displaying pictures or exposures. The cinema computers and peripheral equipment are situated at mutually distanced places.

  • Patent number: 6507949
    Abstract: The invention relates to a method and an arrangement of assigning an information-category and a priority of exposure for spots or blocks of information in a digital information system comprising interfaces for data and telecommunication for round-the-clock transmission of information at places accessible to and frequented by the general public including places where television sets are placed, such that a control center has communication interfaces for coordinating and controlling display devices, with the control center being able to create and update an exposure list in real time. The exposure list contains information including how many times an information is to be exposed during a specific time period. Single spots or blocks of information to a specific information-category and a priority for exposure.

  • Patent number: 6026783
    Abstract: Methods and apparatus for calibrating throttles for engines are disclosed with the methods including positioning the throttle in a predetermined position, detecting that position, and acknowledging the predetermined degree of application of the throttle whereby that predetermined degree of application is locked into correspondence with the predetermined position of the throttle for subsequent use of the throttle. The disclosed apparatus includes an actuator for locking a predetermined position of the throttle within the range of positions into correspondence with a predetermined degree of application of the throttle and acknowledging that predetermined degree of application of the throttle, and a detector for detecting the predetermined position of the throttle.

  • Patent number: 6005534
    Abstract: The invention relates to a digital information system (10) for displaying information on at least one display means with the aid of at least one projector (22). The exposures are presented at places accessible to and frequented by a general public. The information system (10) includes external information mediators (24) and information is controlled dynamically through the medium of a communication interface (26) and through the medium of an exposure handler in a central computer (28). The inventive system also includes a communication interface (14) against an elective number of station computers (34) having connected projector computers (38) which control projectors (22) for displaying pictures or exposures. The station computers (34) and peripheral equipment are situated at mutually distanced places.

    Inventors: Mats Hylin, Mats Dahlgren, Joakim Jonasson
  • Patent number: 5408979
    Abstract: The present invention relates to a device regulation of turbo-charging in an internal combustion engine. The turbo-charging regulation includes a first turbo unit and a second turbo unit each including appropriate turbines and compressors arranged sequentially on the exhaust and the intake sides of the engine. An engine rotational speed sensor is provided issuing a signal indicating the rotational speed of the engine. In addition, at least one pressure sensor issuing a signal indicative of an engine pressure level on the intake side of the engine is also provided. A first valve is associated with the first turbo unit and arranged to direct the engine combustion gases toward the turbine of the first turbo unit in a closed state and to direct the engine combustion gases past the turbine of the first turbo unit in an open state.

  • Patent number: 5115780
    Abstract: Device for limiting the exhaust gas temperature in an internal combustion engine consisting of a thermoelement (2) protruding into the engine exhaust manifold (1) and an electronic control unit (3) connected thereto, which is disposed to send an output signal dependent on the exhaust gas temperature sensed by the thermoelement to the fuel injection system (4) of the engine. When the output signal indicates that the temperature exceeds a maximum-permissible level, an excess of fuel is injected for cooling.

  • Patent number: 5083434
    Abstract: A system for controlling the boost pressure in a turbocharged internal combustion engine comprising a control device (171), an operating device (11, 12, 13) controlled by the control device and operative in controlling the speed of a turbine (4) and means (22) for feeding to the control device (171) signals which represent the true boost pressure prevailing at a location upstream of the engine throttle valve (9). The control device includes a data processor (18, 21) in which there is stored data which relates to theoretic control-valve settings and values which are intended to give boost pressure control values as a function of engine speed. The control device is constructed to compare the true boost pressure with the given control value subsequent to an increase in load with a subsequent rise in pressure over an interval of time.
