  • Patent number: 7222142
    Abstract: The present invention provides methods and systems for archiving of data, that is, for moving a selected data object in a computer system from a first to a second storage location. The selected data object is assigned at least one identifier (ID) that is stored in at least one lock object. The data object is stored at the second storage location and the second storage location is associated with the ID. The data object is then deleted from the first storage location and the ID is deleted from the lock object after the storing of the data object in the second storage location has been completed. Methods and systems can check, by querying the lock object, whether the data to be accessed is subject to a moving process or not. If yes, the access to that data can be postponed until the moving is completed.

  • Patent number: 7173519
    Abstract: A circuit arrangement for phase modulation in an input circuit of a backscattering transponder includes a varactor and at most one capacitor connected in series between two antenna terminals, as well as a varactor control arrangement applying a control voltage to the varactor to selectively vary the capacitance thereof. One of the antenna terminals is connected directly to one of the varactor terminals without a capacitor therebetween. The other antenna terminal is connected either directly or through a capacitor to the other varactor terminal. One antenna terminal and/or one varactor terminal can be grounded. A DC-decoupling capacitor can be connected between a transponder circuit unit or a circuit ground and the common junction of the antenna terminal with the varactor terminal. The circuit arrangement is simple, economical, and uses minimal chip area by omitting further capacitors between the antenna terminals.

  • Patent number: 7158010
    Abstract: A circuit arrangement for phase modulation in an input circuit of a backscattering transponder includes a varactor and at least one capacitor connected in series between two antenna terminals, and at least two voltage sources selectively connected through at least two switches to at least one terminal of the varactor. A control unit selectively opens and closes the switches in response to the data to be phase-modulated onto the backscattered signal. By selectively connecting the different voltage values of the respective voltage sources to the varactor terminal(s) through the switches, the capacitance of the varactor and correspondingly the input impedance of the input circuit are thereby varied, so as to provide respective different phase positions of the phase modulation.

  • Patent number: 7151436
    Abstract: For transmitting data, a receiving/backscattering arrangement receives, modulates and reflects or backscatters electromagnetic waves emitted by a base station. The modulation corresponds to the data to be transmitted and is carried out selectively using first and/or second different modulation methods depending on the received field strength of the received electromagnetic waves. Preferably, phase shift keying is used especially or at least at low field strengths at far range, while amplitude shift keying is used additionally or alternatively for high field strengths at close range. The two modulation methods can be superimposed. A circuit arrangement includes two different modulator arrangements to perform the two modulation methods depending on the received field strength. The second modulator arrangement preferably comprises a multi-stage voltage multiplier circuit with a modulated switching device intervening in one of the stages to achieve the modulation.

  • Patent number: 7107753
    Abstract: A heating device for heating a yarn, in particular in a texturing machine. The heating device comprises a thin-walled heating tube, which can be evenly heated on its circumference by a heating jacket. Fitted within the peripheral wall of the heating tube is an insert, which forms a yarn channel extending between a yarn inlet and a yarn outlet for guiding the yarn. The insert is formed by a special section rail that is open along one long side, and fitted with its opposite long side to the wall of the heating tube. As a result, the yarn channel is formed between the open long side of the special section rail and the wall of the heating tube, so that it is possible to supply heat to the yarn channel directly via the wall of the heating tube.
