Abstract: A high voltage pulse generating system has a latching element coupled in between a ferroelectric generator (FEG) and a load, such as a vector inversion generator. Such a latching element prevents the return of current to the FEG when the FEG undergoes mechanical destruction after depolarization, thereby increasing the useful amount of energy extracted from the FEG. In some embodiments, multiple FEGs are configured with multiple latching elements to deliver multiple high-voltage, high-current pulses.

Abstract: A mounting fixture for detachably fastening cover plates in an aircraft. For fixing, a retaining bracket fixed on the cover plate is snap-fitted onto a retaining pin fixed on a substructure of the fuselage cell. A first holder is fixed on the retaining pin for receiving at least one connecting element, and a second holder is displaceably fitted in a forked holder on the retaining bracket. The forked holder has a roughly U-shaped form with two upright arms each connected at their lower ends by a base plate. Two connecting elements are preferably each fixed in the holders. The connecting elements are formed as electrical and/or optical sockets and plugs each with cabling attached. By swiveling a contacting lever the second holder can be moved linearly to and fro in relation to the first holder and can be introduced and pushed at least in part into the first holder whereby the final electrical and/or optical contact is produced by means of the sockets and the plugs.

Abstract: A universal junction box, which includes multiple methods for securing cables, various kinds of wires and conduits and multiple methods for securing the box within a wall cavity. The front side of the box which can be positioned flush with the installed wall covering includes fittings for attaching a wall plate, switches, plugs, connectors, and electrical/electronic devices to the box. The junction box allows the addition of an extension to the rear of the junction box for a between-wall design for the installation and attachment of similar devices on an opposing wall surface through the same junction box. The junction box also engages extensions to the side of the junction box allowing two or more ganged box configurations, which share the multiple methods for securing the junction box within a wall cavity.

Abstract: A method for intelligent control includes an exchange of historical parameters of events for operating a system and operating a hoist where an electric motor, preferably a DC-motor, is used for lifting and lowering a lifting belt. It can take place at different speeds by registering amperage through the motor and to perform a switching between fast and slow speed when a given current level is reached. The change in hoisting/lowering speed is achieved when a control unit changes the voltage supplied by the battery unit to the DC-motor or changes the frequency of power supply to an AC-motor. The method makes it possible to control the system and to optimize the hoisting/lowering speed for the lifting belt depending on the load thereon.

Abstract: A flap in the covering of a vehicle can be adjusted by flap kinematics between a closed position, in which the flap is situated essentially in the plane of the vehicle covering, and an opening position. In an operationally reliable construction, a vehicle-fixed link path for the passive guidance of a first guiding lever, which connects the flap with the vehicle, is provided in the lateral area of the flap. In the opposite lateral area of the flap, a second, actively guided guiding lever is arranged which is acted upon by a motor-driven actuator.

Abstract: A plug connector with a hollow, cylindrical, metallic housing (1), within which is centrically disposed an inside contact pin (8, 9, 10) extending at least approximately over the entire axial length of the housing (1). In order to make contact with the reciprocal plug connector, the inside contact pin (8, 9, 10) is accessible at a first front side of the housing (1). The first front side is open toward the plug side of the plug connector, such that a latch interlock (6, 7) and a contact basket (5), which extends out of the open front side of the housing (1) and which is rotatably mounted about the longitudinal axis of the housing (1), are disposed co-axially with the inside contact pin (8, 9, 10). The contact basket (5) makes permanent electrical contact with the metallic housing.

Abstract: This invention includes a sensor, a time delay trigger circuit, and a power source. The sensor monitors an ambient light level and produces a sensed signal related to the ambient light level. The time delay trigger circuit is in electrical communication with the sensor for determining whether the ambient light level remains reduced below a predetermined level for a specified time. The time delay trigger circuit includes a counter/timer circuit, a comparator circuit, a timing gate circuit, and an output driver. The counter/timer circuit receives the sensed signal from the sensor and initiates a count sequence when the ambient light level is below a predetermined level. The counter/timer circuit provides a count value output representing elapsed time. The comparator circuit includes a plurality of switches used to set the specified time delay. The comparator circuit compares the count value output from the counter/timer circuit with the switches.
