  • Patent number: 7868273
    Abstract: In order to make it possible to direct sufficient microwave energy at a target with an electronic device which is to be interfered with or to be destroyed, the beams (7) from at least two antenna arrays (10) are focused on an effective area (8) in the vicinity of that target, preferably from a vehicle (3) which is equipped with these arrays (10). For effective super-imposition of the emitted microwave energy (7) in the emission direction of in each case one of the arrays (10), the use of an arc for discharging the capacitance (43) of the resonator via its spark gap (13) is observed, and is recorded quasi-continuously optoelectronically. The electrode separation of the spark gap (13) or the fluid pressure of the dielectric in the vicinity of the spark gap (13) is then varied by control elements such that all of the spark gaps (13) in an array (10) ignite virtually at the same time, so that their discharge current pulses which lead to the emission of the microwave energy (7) start virtually in phase.

  • Patent number: 7842907
    Abstract: A microwave generator (10) having a hollow central electrode (12) with a front face including hollow emmission element (18), and having an outer electrode (14), which coaxially surrounds the central electrode (12) along an axially extending resonator section (16). The two electrodes (12, 14) define a spark gap (36) and are connected to a high-voltage source (38). An ultracompact microwave generator (10) is implemented by the high-voltage source (38) being arranged in the hollow central electrode (12) of the microwave generator (10) rather than on the outside thereof.

  • Patent number: 7741783
    Abstract: A microwave generator has at least one resonator with two mutually opposite resonator electrodes which are separated by a spark gap. The spark gap breaks down when a high-voltage is applied. The resonator electrodes are designed in the area of the spark gap such that they result in a two-dimensional or three-dimensional section with a substantially constant, minimum electrode separation.

  • Patent number: 7002300
    Abstract: Intensive microwave radiation in particular of great band width and energy over a relatively long period of time in the form of long pulse packets with a high pulse repetition frequency and a very high frequency spectrum can be achieved if microwave irradiation is effected during the discharge of a capacitive high-voltage generator (35) by way of the antenna (26) into a series of successive capacitors (13) to be connected in parallel. They are preferably constructed in the form of a concentric stack, connected to the antenna (26), of which the outer electrodes (16) which are at a reference potential are in the form of a continuous tube within which annular electrodes (15) are disposed on a carrier (20) in axially spaced relationship with each other in such a way that at the same time they act as the electrodes of arc switches (39) for successively switching on subsequent capacitors (13).

  • Patent number: 6424908
    Abstract: In the method of inputting information in an electrical unit, after input of an alphabetic character the character itself, or, for the case in which one or more characters have been input prior to the input of the alphabetic character, the character string formed by the first to the last input character is compared with information entries in a comparison set of information, and, when the input character is the same as the first character of one of the information entries in the comparison set or when the character string agrees with the beginning of one of the information entries in the comparison set, this information entry is offered for input to the electrical unit. The information entry offered for input is preferably displayed with all its characters on a display device prior to input. The offered information entry can then be rejected by the operator of the electrical unit by inputting another alphabetic character immediately following input of the alphabetic character.
