  • Patent number: 10501386
    Abstract: A solid propellant compact (10) in the form of a compact made of a powdered and/or granulated solid propellant, especially for inflators and/or actuators of a vehicle occupant restraint system, includes at least one recess on at least one of its sides. Solid propellant compacts (10) of this type are provided in an inflator (14) comprising at least one combustion chamber. A module includes such inflator (14) with an airbag inflatable by the inflator (14). A pyrotechnical drive unit (30) comprising a housing (32), a piston (34) movable in the housing (32) includes solid propellant compacts (10) of this type.

  • Patent number: 8700914
    Abstract: A system and method for changing safety-relevant data for a control device is provided wherein an authorized user inputs new or altered safety-relevant data, which is received on a data processing installation. A first checksum for the safety-relevant data is established and stored along with the safety-relevant data in at least one data record on the data processing installation. An enable code may also be stored in the at least one data record. This enable code may be produced by a code generator and encrypted by a key module. The data processing installation then reads back the safety-relevant data from a memory in the data processing installation, thereby allowing a comparison of the received safety-relevant data and the read back safety-relevant data. A second checksum is generated in a case where the comparison resulted in no differences. The second checksum may also be stored in the at least one data record.

  • Publication number: 20130247790
    Abstract: The invention relates to a propellant pellet for pyrotechnical safety devices in vehicles, such as airbag modules, belt tensioners, micro-inflators and igniters. The propellant pellet according to the invention has a substantially cylindrical shape and can be obtained by dry injection of a powdered propellant composition. The pellets have a maximum diameter of 2 mm and preferably a relative bulk density, defined as ratio of bulk density of the propellant pellets to the maximum theoretical density of the propellant composition, of at least 0.5. A propellant charge, an igniter and an inflator each comprising a plurality of said propellant pellets are provided.

  • Patent number: 7912558
    Abstract: A PLC for distributed control includes a storage unit that stores common-data specifying information for specifying common data shared by a corresponding PLC and another PLC, a receiving unit that receives the common-data specifying information from another PLC, and a collating unit that collates the common-data specifying information stored in the storage unit with the common-data specifying information received by the receiving unit.

  • Patent number: 7689301
    Abstract: A safety control device for ensuring safety of an object to be controlled, including: communication unit which is used for communication with another safety control device and uses a frame including a test bit string T having correlation with a base bit string B; and detection unit which compares with the base bit string B the test bit string T included in a frame having been received from another safety control device, thereby determining the number of bit errors in the frame.

  • Patent number: 7651126
    Abstract: A device for protecting goods and/or persons including a security element; and a gas generating system connected to the security element and including an explosive charge formed at least of: a primary pyrotechnic compound, in a first chamber, initiated by at least one initiator having a reinforcing charge and including at least one propellant having an optionally adjusted oxygen balance, and a secondary compound, in a secondary chamber, including an oxidant constituent capable of delivering only gas by decomposition and at least one reducing additive having a function of contributing nitrogen, the additive being present in a proportion by weight less than about 70% of the weight of the primary-secondary compound.
