  • Patent number: 10307757
    Abstract: An automatic analyzer cartridge, spinnable around a rotational axis, has aliquoting and metering chambers, a connecting duct there between, and a vent connected to the metering chamber and nearer to the rotational axis than the metering chamber. The metering chamber has side walls that taper away from a central region. Capillary action next to the side walls is greater than in the central region. A circular arc about the rotational axis passes through a duct entrance in the aliquoting chamber and a duct exit in the metering chamber. The cartridge has a downstream fluidic element which is part of a fluidic structure for processing a biological sample into the processed biological sample. A valve connects the metering chamber to the fluidic element, which is fluidically connected to the fluidic structure. The fluidic structure receives the biological sample and has a measurement structure for enabling measurement of the processed biological sample.

    Abstract: A planetary gear assembly, in particular for an electromechanical service or parking brake for a motor vehicle. The planetary gear assembly can include a central sun gear, a plurality of planetary gears rotatably mounted on a planetary carrier, and a ring gear enclosing the planetary gears. The planetary gears can be mounted by the planetary carrier, such that the planetary gears roll off both the sun gear and the ring gear, whereby the sun gear, the planetary carrier or the ring gear is non-rotatably held by a holding unit with a holding torque. A force-sensing device can be arranged between the holding unit and the non-rotatably held element, or between the holding unit and an intermediate component non-rotatably connected to the held component. The force-sensing device can measure the force acting between the held component and the holding unit as a result of the holding torque.

  • Patent number: 9415758
    Abstract: The invention relates to a method for providing haptic information to the driver of a motor vehicle, equipped with a brake-by-wire brake system, about the operating state of the brake system, in which method the brake pedal characteristic is generated by a pedal travel simulator, in the form of a functional relationship between the brake pedal opposing force and the brake pedal travel, and is modified as a function of an operating state. In order to provide the driver with the haptic information channel via which electronically controlled information can be communicated to the driver during braking, without the impression of a defect arising, the invention proposes that a basic brake pedal characteristic is generated by a passive simulator spring which assigns pedal travel, on which pedal return travel transporting the haptic information is superimposed, to a given pedal force in an unchanging, constant relationship.

  • Publication number: 20150316371
    Abstract: A method for determining the absolute position of a linear actuator is described. In the process, the rotational angle position of the rotor of the corresponding electric motor of the linear actuator is determined by a first sensor. In addition, the rotary angle position of a transmitter wheel of a second sensor coupled to the rotor is determined by means of a special transmission ratio. The absolute position of the linear actuator is derived from the differential value of the determined rotary angle positions. The method can be implemented in a simple and inexpensive manner.
