  • Patent number: 8239089
    Abstract: An apparatus and a method for detecting deformations of a vehicle component on a motor vehicle are disclosed, which are capable of unambiguously determining the location and temporal progression of the deformation, as well as the severity of the deformation, within a very short time after the deformation of the vehicle component begins. A grid module having a grid, an emitter component with a light emitter; and a detector with at least one sensor unit are hereby provided on the vehicle component. A beam path of a light beam between the light emitter and the detector is alternatingly interrupted when the grid is displaced relative to the emitter component due to a deformation of the vehicle component. The detector detects a signal in form of light pulses generated by the interruption of the light beam and the light pulses are transmitted as a time-modulated signal to an evaluation unit.

  • Patent number: 8239091
    Abstract: The invention relates to a method for detecting a rotating stall fault in a compressor (12) which is driven by means of a three-phase current motor (8) fed by an inverter. According to the invention, an instantaneous estimated value (^m) which is calculated from measured power converter output currents (iS1, iS2, iS3) and a measured rotational-speed-proportional signal (?) is compared with an instantaneous setpoint value (m*) determined from a measured rotational-speed-proportional signal (?) and a predetermined rotational-speed-proportional signal (?*), in such a way that in the case of inequality a signal (SRS) is generated which indicates that the rotating stall fault has occurred. In this way, it is possible for the rotating stall fault to be detected without pressure sensors and/or oscillation pickups in a compressor (12) which is driven with a three-phase current motor (8) fed by inverter.

  • Patent number: 8231307
    Abstract: A tensioning device in particular for bracing string sections of a string includes a traction element, which extends between an abutment and an adapter on the rear end of the string. A linear tensioning device is arranged in parallel relationship to the string for applying the tension force.

  • Patent number: 8229591
    Abstract: Disclosed is a method for programming the progress of an injection molding cycle of an injection molding machine. The injection molding cycle includes several sequences which are manually started as a whole or in part in a setup mode and in a teaching mode. In the setup mode, parts of the injection molding machine are first actuated and are tested as to the functionality thereof. The tested parts are then actuated once again in the teaching mode according to the desired sequence of movements, said sequence of movements being stored in a controller of the injection molding machine. Specific actions such as building up and reducing forces and generating holding pressure can also be taught. The individually taught sequences can then be freely combined into new processes in a controller having a suitable operator interface and can be repeated multiple times.

  • Patent number: 8227951
    Abstract: In a three-phase permanent-magnet synchronous machine, a pole gap and a skew of permanent magnets on the rotor are designed such that oscillating torques which are caused by the fifth and seventh harmonics of the stator field and of the rotor field are mutually reduced. In particular, the skew can be chosen as a function of the pole gap, such that the majority of the respective oscillating torques is neutralized. This results in minimal torque ripple.

  • Patent number: 8217774
    Abstract: The invention relates to a method for controlling a locking system of a motor vehicle wherein, as the states of the locking system, there is an unlocked state, a locked state from which it is possible to switch to the unlocked state via at least a first operating element inside the vehicle, and a security state in which by simply activating a first operating element it is not possible to switch to the unlocked state. The aim of the invention is to propose a method that allows a person inside the motor vehicle to still leave the motor vehicle despite user activation of the security state without substantially easing the opening of the motor vehicle from the outside by an unauthorized third party. Four concepts are proposed that can all be implemented in combination to great benefit. They enable a person still inside the vehicle to leave the motor vehicle upon activation of the security state.
