Abstract: An electrical component includes a substrate, a first electrode layer, a structured growth layer that is thinner than the first electrode layer, a piezoelectric layer, and a second electrode layer. The growth layer is on the first electrode layer, the growth layer is structured relative to the first electrode layer, and the growth layer has a smaller surface area than the first electrode layer. The growth layer may be selected to support ordered growth relative to the piezoelectric layer.

Abstract: The invention relates to a grip for a handgun, in particular a pistol, having a grip module (1) made of plastic and a metal carrier element (2) that is insertable into said grip module (1). In order to enable a simple and cost-effective adaptation to the widest variety of demands of the marksman, a magazine shaft (4), projecting downward from the grip module (1) and onto which is slipped a grip shell module (3), is formed as a part of the carrier element (2).

Abstract: The invention pertains to a trigger mechanism for handguns, particularly pistols, with a striking lever (2), a first striking spring (3) that is assigned to the striking lever (2) and serves for acting upon the striking lever (2) in the firing direction, a trigger (12) and a trigger rod (13) that is connected to the trigger (12) and releases the striking lever (2) in a tensioned position in order to fire a shot. In order to generate a constant firing energy with variable trigger resistances and trigger paths, the striking lever (2) is acted upon in the firing direction by a second striking spring (5) that is arranged parallel to the first striking spring (3).

Abstract: In an electrical component with thin-layer construction that has a piezoelectric functional layer, the layer quality of the functional layer is improved in that a growth layer is provided between the electrode layer and the piezoelectric layer. Thus the function of the electrode layer is separated from that of a growth-supporting layer, whereby the functions can be optimized using separate layers independent of one another. Inventive components can be embodied as BAW resonators, thin-layer piezo-actuators, or piezo-sensors.

Abstract: A safety for a hand firearm with a firing lever, a firing pin, a safety element allocated to the firing pin, a trigger rod that can be activated by a trigger, and a transmission element, which is coupled to the trigger rod and through which the safety element can be moved from a safety position for blocking the firing pin into a released position for releasing the firing pin. To guarantee a high degree of safety against undesired firing of a shot even for a small trigger path and low trigger weight, the transmission element contains a control element, through which the transmission element can be activated in a predetermined trigger position of the trigger by means of the firing lever for moving the safety element into the released position.

Abstract: An apparatus for manufacturing low diameter, high quality glass wool fibers, and more particularly to a spinner for centrifuging low diameter glass wool fibers to improve light-density building insulation is disclosed. The spinner includes a number of glass orifices positioned predetermined column angle and provides a hole pattern that improves the quality of the glass. The improved hole pattern is determined by experimentation and may be implemented in any glass fiberization process.

Abstract: A modularly constructed electrical component having a module substrate, preferably, of Si, and having one or more preferably un-housed chips placed on the module substrate while being electrically connected thereto and each joined to the module substrate, e.g., by direct wafer bonding. A recess is provided in the module substrate so that a closed hollow space is formed when the chip is joined to the module substrate. The hollow space is not formed by a protective cap, which surrounds the chip and, with the module substrate, closes it on all sides. Rather it is formed by the joining of opposing contact areas of the chip underside and of the upper side of the module substrate. The component can be economically produced because it does not require a protective cap for creating the hollow space. The component has a higher yield than monolithic integration of the functional units.

Abstract: In a rail track system having transition points, a locomotive having a navigation system (such as a combined inertial/GPS location system) moves along an initially known track and enters the “halo” surrounding a track transition to begin data collection/logging to accumulate successive position information data points as the locomotive moves into, progresses through, and exits the “halo.” The collected data for movement within the “halo” is then subject to a best fit assessment relative to the data pre-stored in the track database.

Abstract: A component operating with bulk acoustic waves has a carrier substrate, a thin-film resonator and an acoustic mirror arranged between the resonator and carrier substrate. The acoustic mirror is formed by at least one high acoustic impedance layer, which is covered by a low acoustic impedance layer and the uppermost low impedance acoustic layer is planarized to form a flat planar surface on which the thin-film resonator is formed.

Abstract: A component working with acoustic bulk waves is provided that has a multi-layer substrate, where the multi-layer substrate comprises an integrated matching network and further circuit elements for adapting the electrical filter properties and can serve as carrier substrate for thin-film resonators.

Abstract: A locomotive location system and method utilizes inertial measurement inputs, including orthogonal acceleration inputs and turn rate information, in combination with wheel-mounted tachometer information and GPS/DGPS position fixes to provide processed outputs indicative of track occupancy, position, direction of travel, velocity, etc. Various navigation solutions are combined together to provide the desired information outputs using an optimal estimator designed specifically for rail applications and subjected to motion constraints reflecting the physical motion limitations of a locomotive. The system utilizes geo-reconciliation to minimize errors and solutions that identify track occupancy when traveling through a turnout.
