  • Patent number: 7123444
    Abstract: A tape cassette has a housing which contains at least one magnetic tape wound on a tape hub, and a semiconductor memory which contains memory data. The tape cassette also includes at least an optical transmitter, and a circuit which has access to the memory contents and which can read out the memory contents from the memory and embody the memory contents in an optical signal, which is transmitted out of the housing by the optical transmitter. The memory data may characterize data stored on the magnetic tape. The cassette can include a further memory which contains data uniquely identifying the cassette, and this data can also be read out and embodied in optical signals which are transmitted out of the housing.

  • Patent number: 6849295
    Abstract: For manufacturing a winding protection for tape-wound cores that are surrounded with a winding, a polymer film is provided that is deposited onto the tape-wound cores from a vapor phase at room temperature in a drum process. Due to the end face penetration of the polymer into the tape-wound cores, the polymer is solidified and simultaneously surrounds all sides with a thin, uniformly adhering and directly windable layer.

  • Patent number: 6841997
    Abstract: In a nuclear magnetic resonance tomography apparatus and a method for the operation thereof, on the basis of the 3-point Dixon method, spin collectives having different chemical shifts are separated by means of information maximization despite great field inhomogeneities. The unwrapping of the phases is implemented over interconnected pixel regions (phase unwrapping) proceeds initially only in regions with high signal amplitude and the regions of lower amplitudes are only successively acquired by increments. These are then assigned to the respectively correct spin type, such as fat or water.

  • Patent number: 6754535
    Abstract: In a method and an apparatus for verifying the occurrence of an evoked response in the atrium, following emission of a stimulation pulse to the atrium, an impedance signal is measured in a time window following the emission of the stimulation pulse. The impedance signal is high pass filtered and a characteristic of the high pass filtered impedance signal, such as its amplitude or its morphology, is compared to a predetermined criterion in a comparison unit. The occurrence of an evoked response is verified if the characteristic equals or exceeds the predetermined criterion. The occurrence of an evoked response can therefore be monitored on a beat-to-beat or pulse-to-pulse basis.

  • Patent number: 6748273
    Abstract: In a method and an apparatus for detecting the status of a battery in an implantable heart stimulator, the battery impedances measured and an increased value of the measured impedance is detected, from which an impedance based value of the remaining battery capacity is determined. The increase in impedance is analyzed to determine whether the impedance increase is a reliable indicator of the remaining battery capacity. If it is determined that the impedance increase is not reliable for determining the battery capacity, the total charge depletion of the battery is measured and a charge depletion-based value of the remaining battery capacity is determined.

  • Patent number: 6716673
    Abstract: In a two-pole SMT miniature housing in leadframe technique for semiconductor components, a semiconductor chip is mounted on one leadframe part and is contacted to a further leadframe part. The further leadframe part is conducted out of the housing in which the chip is encapsulated as a solder terminal. No trimming or shaping process is required and the housing is tight and is capable of further miniaturization. The solder terminals as punched parts of the leadframe are conducted projecting laterally from the housing sidewalls residing opposite one another at least up to the housing floor which forms the components' mounting surface. The chip mounting surface and the components' mounting surface form a right angle with one another.

  • Patent number: 6717701
    Abstract: In a method for processing signals in an electronic engraving machine for engraving printing forms, engraving control signals for guiding the stylus of an engraving element are obtained from engraving data representing predetermined tone values between “light” (white) and “dark” (black). The stylus engraves a series of cups in the printing form. The cup depths determine the tone values actually engraved. Before engraving, the engraving control signals corresponding to “light” and “dark” are calibrated by adjustment variables so that the engraved “light” and “dark” tone values correspond to the predetermined “light” and “dark” tone values. So that the “light” engraved tone value remains constant when the “dark” tone value changes, the difference between the old “dark” adjustment variable and a new “dark” adjustment variable is formed before engraving.

  • Patent number: 6714093
    Abstract: In a dynamics compressor, an analog signal to be compressed is supplied to a first amplifier stage as an input signal, and the output signal thereof is supplied to the next amplifier stage as an input signal, and so on for a number of successive amplifier stages. Each amplifier stage amplifies its input signal with a stage amplification until it reaches a stage limit level. The analog signal and the respective output signals of the amplifier stages are summed in a summation stage to form a sum signal. Above a minimal level, the magnitude of the curve of the sum signalroughly corresponds to an exponent characteristic of the magnitude of the analog signal.

  • Patent number: 6710686
    Abstract: In a method for the fast acquisition of a magnetic resonance image, magnetic resonance signals from an imaging region are conditioned with magnetic gradient fields that define a spatial frequency space so that the spatial frequency domain is occupied with magnetic resonance signals having trajectories that are radially directed and proceed through a projection center, and the imaging region is divided into sub-regions with an antenna of an antenna array respectively allocated to each sub-region. The antennas have respective positions relative to the projection center such that the antennas simultaneously receive the magnetic resonance signals and form reception signals from the magnetic resonance signals according to their sensitivity. The number of radially directed trajectories is of only such a size so that the sub-zones regardless of their spatial position in the imaging zone from the respective reception signals can be unambiguously reconstructed.

  • Patent number: 6710996
    Abstract: The invention is directed to a surge arrestor having a middle electrode and at least one outer electrode, in which an electrically conductive spring clip is secured to the middle electrode and exerts a spring power on the outer electrode; in which an electrical component part that is non-conductive at the trigger voltage of the surge arrestor and generates heat given a flow of current is arranged between the spring clip and the outer electrode; in which the spring clip lies against an electrically conductive contract element that is secured to a spacer element using a fusible mass and that is spaced from the outer electrode; and in which, when the fusible mass melts, the contract element is pressed against the outer electrode by the spring clip. The trigger mechanism has the advantage that it reacts very quickly and thereby reduces the formation of sparks and the fire hazard as well.
