  • Patent number: 7992443
    Abstract: A sensor design, respectively a micromechanical sensor structure for capacitive relative-pressure measurement, that will allow very small pressure differentials to be reliably recorded at high absolute pressures even in harsh, particle-laden measuring environments. For that purpose, the micromechanical sensor element includes a deflectable diaphragm structure which is provided with at least one deflectable electrode, and a fixed support structure for at least one fixed counter-electrode which is located opposite the deflectable electrode. The diaphragm structure includes two mutually parallel configured diaphragms that are joined rigidly to one another via at least one connecting crosspiece, so that each application of force to one of the two diaphragms is directly transmitted to the respective other diaphragm.

  • Patent number: 7992432
    Abstract: A method for operating an internal combustion engine for a motor vehicle, in which a first signal is determined, which characterizes a torque of the internal combustion engine. In order to provide a method for operating an internal combustion engine for a motor vehicle in which a torque of the internal combustion engine is determined even more precisely, in particular in the region of a zero crossing of the torque, a second signal, which characterizes a state variable of the internal combustion engine and/or the motor vehicle that differs from the torque is determined from the first signal, at least one third signal is recorded, which characterizes a measured value of the state variable, the second signal and the third signal are compared to one another, and the first signal is corrected on the basis of the comparison.

  • Patent number: 7992947
    Abstract: A method for activating a two-stage switching valve including a first stage which has a small flow cross-section and a second stage which has a larger flow cross section, the switching valve being situated between a main brake cylinder and a hydraulic pump in a hydraulic brake system. The pressure equalization knock on opening the switching valve is substantially reduced by activating the switching valve in a first control phase via a control signal having a low amplitude, due to which only the first stage of the valve is first opened, and by activating the valve in a second phase via a control signal having a higher amplitude.

  • Patent number: 7992442
    Abstract: A method for reducing microcrack formation and crack growth in the glass carrier of a component having a micromechanical sensor element that is bonded to the glass carrier. The upper side of the glass carrier acts as a bonding surface for the sensor element. The rear side of the glass carrier, situated opposite the upper side, acts as a mounting surface for the component, and the glass carrier has side surfaces that connect the upper side and the rear side. In particular, the glass carrier is formed by a segment of a glass wafer into which at least the contours of the glass carrier have been stamped, so that at least the areas produced in this way of the side surfaces of the glass carrier and the rear side of the glass carrier form a surface that is largely closed and free of microcracks.

  • Patent number: 7992613
    Abstract: A method and an arrangement for the production of composite work pieces of layers laminated to each other, with at least one layer representing a glass plate. First, at least one composite work piece is laminated in a lamination press under the effects of pressure and heat in order to at least activate the adhesive material used for lamination. Then the composite work piece is removed from the lamination press and transported into a curing station and/or cooling station for curing and/or cooling. A testing device for detecting broken glass in the composite work piece is arranged between the lamination press and the curing station or between the lamination press and the cooling station, which detects potentially present broken glass by testing the inherent stability of the composite work piece.

  • Publication number: 20110190594
    Abstract: A medical sleep disorder arrangement integrates into current diagnosis and treatment procedures to enable a health care professional to diagnose and treat a plurality of subjects suffering from insomnia. The arrangement may include both environmental sensors and body-worn sensors that measure the environmental conditions and the condition of the individual patient. The data may be collected and processed to measure clinically relevant attributes of sleep quality automatically. These automatically determined measures, along with the original sensor data, may be aggregated and shared remotely with the health care professional. A communication apparatus enables the healthcare professional to remotely communicate with and further assess the patient and subsequently administer the treatment. Thus, a more accurate diagnosis and more effective treatment is provided while reducing the required clinician time per patient for treatment delivery.

  • Publication number: 20110185887
    Abstract: A brake booster includes a housing configured for mounting to the master cylinder of a braking system. The housing defines a bore for receiving a power piston and an end cap, with a return spring disposed between the head of the piston and end cap. The housing and end cap define a recess and a rib sized to be received within the rib but configured for an interference fit between the end cap and housing outside the recess. The interference fit is calibrated to require a force to push the end cap into the bore that exceeds the force generated by the return spring when it is compressed between the end cap and the piston head. The recess and rib at least temporarily retains the spring within the bore until the brake booster is mounted to the master cylinder.

  • Publication number: 20110186158
    Abstract: Delivery units are already known which have a drive rotor and an output rotor driven by the drive rotor, which are supported in a housing, interact in a meshing manner through a spur toothing in each case and draw fluid through at least one inlet and push said fluid out through an outlet, wherein the inlet and the outlet are separated from each other by two separating webs. In order to control the flow rate through the delivery unit, a rotational speed control, a bypass control, or, for gases, a suction throttling, for example, can be carried out. A rotational speed control is energy efficient, but very expensive, because an electric motor must be used, the rotational speed of which can be controlled. In the bypass control, the fluid is delivered from the outlet through a bypass back to the inlet, which however is energetically unfavorable and connected to hydraulic losses.
