Abstract: Effects of capacitive resistances on the transmission of data between electronic igniters of an ignition system and a device for programming and triggering igniters are avoided by the disclosed method. Prior to a planned communication of an igniter with the device, a dc voltage is applied to the ignition circuit for a predetermined length of time. This voltage is higher than the voltage provided for generating the signals with which the data are generated. Subsequently, the signals that the igniter transmits in response are produced with a lower voltage than the previously elevated voltage and the dc voltage is increased once again prior to the response to an additional igniter.

Abstract: The invention relates to an ignition unit (1) suitable for triggering an active system, such as an airbag or safety belt. The ignition unit comprises an ignition charge (7) located in a housing (2), which can be fired by means of an ignition bridge (6) positioned on a support element (5), as well as at least one contact pin (13a, 13b, 13c) which protrudes from the housing (2) and via an electronic ignition system (9) is electrically connected to the ignition bridge (6). The electronic ignition system (9) is surrounded by an envelope (10) made of a shock-absorbing material. The ignition bridge (6) is not covered by the envelope (10) so that during ignition the pressure exerted on the electronic ignition system (9) is cushioned. This prevents damage to the sensitive electronic components of the electronic ignition system (9) situated on the support element (5).

Abstract: An igniter element has two contacts (12, 13) which are on the contact side of a support body (11), and which are connected via a resistance element (15). By current feed to the contacts (12, 13), a primer mix (17) is ignited on one active side of the support body (11). The support body (11) is placed in a fixing device (10), whereby the former is fitted with at least one stop spring (18) which catches on a stop shoulder (21) of the holding device. Furthermore, the support body (11) has a recess (22) on the front-side in the region of the stop spring (18), which recess is open in the direction of the active side. After igniting the primer mix (17), pressure builds up on the active side, so that the outer surface (23) of the stop spring (18) is pressed against the inner surface of the fixing device (10).

Abstract: The invention relates to a method for producing a cartridge consisting of a case and a projectile, characterized in that, once the cartridge is fully manufactured, a capillary active, acrylate-based adhesive sealing agent is applied in a controlled manner to the gap arising in the inner mouth of the case when the projectile is inserted therein, in a sufficient quantity as to guarantee full sealing of said gap.

Abstract: The bumpers of motor vehicles nowadays are being used to an increasing extent to carry components of small size in which their position on a bumper is especially advantageous for their operation due to its exposed location. For example, it is known to build into the bumpers of vehicles flashers, parking lights and especially distance sensors (parktronic sensors, abbreviated PTS) which detect the distance from other vehicles or obstructions and are designed as parking aids. The components must be mounted such that when the bumpers are affected, especially by mechanical shock, any loosening or dropping out will be impossible. At the same time the mountings must be able to be made simply and inexpensively. It is therefore proposed according to the invention that the tongues be affixed by feet to the bumper, or in case of a bumper of modular design, to one of its modules, and be positioned opposite the opening.

The wound body (1) forms a single piece. The winding density of the wound body (1) varies along the length of the wound body (1) so that distribution of the threads (3) optimally matches the charge of the shell (12).

Abstract: In ignition elements where the energy required to ignite the charge is produced using a laser source, the laser light is injected by means of an optical fiber or a laser optics system enabling the laser light to be focused onto the charge at the required intensity for ignition. Transmission losses and injection losses occur while the laser light is transmitted by means of optical devices or optical fibers. Known ignition devices are also complicated in terms of construction. According to the invention, the laser light source is a laser diode (3) and the explosive (4) that is to be ignited is arranged directly on the part (12) of the housing (8) of the laser diode (3) that allows the laser light (13) to pass through it.

Optionally, the projectile (1) conducts a single trajectory adjustment with a fixed value.
