| 20080258446 | Method for the production of a gas bag packet for an airbag module - A process for producing an airbag packet for an airbag module is provided. The airbag is folded up in a folding apparatus to form an airbag packet. Then, the airbag packet is enclosed in a gastight manner by a flexible envelope, wherein the airbag packet is at least partially enclosed by the envelope while it is still in the folding apparatus. | 10-23-2008 |
| 20110079993 | AIRBAG MODULE FOR A MOTOR VEHICLE - The invention relates to an airbag module for a motor vehicle, comprising a gas sack, that can be inflated in order to protect a person by feeding gas into the gas sack, an openable reservoir for storing a coolant, wherein the reservoir comprises a first and a second portion, the second portion connected to the first portion, at least one outflow opening of the reservoir formed in the second portion, through which the coolant, for cooling the gas fed into the gas sack, can leave the reservoir, and a closure element for closing the outflow opening. According to the invention it is provided that the closure element divides the reservoir into the two portions, and that the coolant is arranged in the first portion, wherein the closure element seals the first portion of the reservoir with respect to the second portion of the reservoir. Further, the invention relates to a method for producing an airbag module. | 04-07-2011 |

| 20090070050 | Method for fault detection and diagnosis of a rotary machine - Modem rotary machine production requires built-in fault detection and diagnoses. The occurrence of faults, e.g. increased friction or loose bonds has to be detected as early as possible. Theses faults generate a nonlinear behavior. Therefore, a method for fault detection and diagnosis of a rotary machine is presented. Based on a rotor system model for the faulty and un-faulty case, subspace-based identification methods are used to compute singular values that are used as features for fault detection. The method is tested on an industrial rotor balancing machine. | 03-12-2009 |
| 20110067493 | Method for the automatic detection and identification of errors in a balancing machine - A method is disclosed for the automatic detection and identification of errors in a balancing machine during operation, in which a rotor provided with an unbalance is rotatably mounted in a vibratory bearing in the balancing machine and is set in rotation by a drive, the rotational frequency of the rotating rotor and the vibrations stimulated by the rotor are measured and measurement signals which comprise the measured values of the rotational frequency and the vibrations are generated and delivered to an evaluation computer. The evaluation calculation is based on mathematical models of the dynamic properties of the balancing machine which describe stimulations of the machine structure due to the unbalance, in particular in the balancing planes, and/or due to the rotor geometry and/or due to the bearing and/or possible damage to the bearing. Features such as vibration characteristics and/or process parameters are calculated by a signal-model-based method from the measurement signals, and discrepancies are established by comparing the calculated features with predetermined normal features of an error-free process. | 03-24-2011 |
