  • Patent number: 11974719
    Abstract: In summary, to simplify operation of a medical image acquisition system, it is proposed that the image acquisition system continuously monitors a current image acquisition situation and assigns at least one new function to at least one, preferably manual, operating element, which is adapted to a detected new image acquisition situation, in response to a change in the image acquisition situation, to the extent that said newly assigned function is adjustable and/or operable with the at least one operating element. To this end, the image acquisition system can detect the change in the image acquisition situation using predefined parameters by means of sensors and/or through communication with peripheral units and/or preferably through image analysis of an image sequence which is recorded with an image sensor of the image acquisition system.

  • Patent number: 11967437
    Abstract: A control rod position indication system is for a nuclear reactor with a reactor core and at least one control rod which is movable along a linear path of movement for controlling reactivity of the core. The system includes a permanent magnet mounted on the control rod or a corresponding drive rod, and a number of reed switches arranged around the path of movement in order to be switched by a magnetic field generated by the permanent magnet when passing by. The permanent magnet has a north-south axis whose orientation is constant during movement, and the respective reed switch has a number of reed contacts which are aligned along a longitudinal axis. The longitudinal axis of at least one reed switch is inclined relative to the north-south axis of the permanent magnet, and the angle of inclination has an absolute value within a range from 15 to 65 degrees.

  • Patent number: 10138820
    Abstract: An excentric pin for an electronic throttle control assembly, which is used to adjust the default position of at least one spring used to control the position of a valve plate, where the valve plate is located in an opening of a housing in the electronic control assembly. The excentric pin is used to adjust the default angle of the valve plate to have an angular tolerance of +/?0.10°. The excentric pin is slideably pressed into an aperture of the housing of the electronic throttle control assembly, and turned using some type of driver. The electronic throttle control assembly may be a one-spring design, or a two-spring design, where the two-spring design requires only one spring pin and the excentric pin. Also, the excenter pin may be used to adjust the position of the sector gear, e.g., function as the lower mechanical stop to provide a minimum opening angle for low leakage, and a minimum opening angle to avoid throttle plate corking into opening of the housing.

  • Patent number: 9657650
    Abstract: A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

  • Patent number: 9452704
    Abstract: A lighting device for vehicles having an optical fiber including a flat segment with two opposing flat sides, a light decoupling area, and a light coupling area. The light decoupling area in which light relayed by the flat sides is output in the primary direction of emission. The light coupling area couples the light into the optical fiber, and is arranged on a free end of a light coupling element which is perpendicular to the flat segment and projects from the same. A deflection structure is arranged between the light coupling element and the flat segment for the purpose of deflecting the light toward the flat segment. A rigid circuit board runs parallel to the flat segment. The circuit board is configured with a number of light sources which are each functionally assigned to the light coupling elements.

  • Patent number: 8289726
    Abstract: An electronic device (10) has a screen (12) protecting against radiofrequency electromagnetic fields, wherein the screen is formed by an at least partially conductive cap (12). In order to avoid the formation of a defined conductive connection between the cap (12) and a reference potential, conductive two-dimensional regions (30) of the cap (12) are arranged in electrically insulated fashion at a short distance parallel to at least one two-dimensional region (42) of a conductor (22) of a reference potential. The two-dimensional regions act as a capacitor and a capacitive coupling (12) to the reference potential is produced which eliminates or attenuates radiofrequency electromagnetic interference fields, which enter the electronic device or are emitted from it.
