摘要:
Methods, computer readable medium and systems are provided for moving data objects from a first storage location to a second storage location. One or more data objects may be selected having an identifier from a first storage location. The ID may be stored in a second lock object. Systems and methods consistent with the invention may determine whether the ID is stored successfully, and upon a successful storage, may store the ID in a first lock object. The data object is stored at a second storage location and the data object is deleted from the first storage location. After the ID has been stored in a first lock object, the ID is then deleted from the second lock object.

Methods, computer readable medium and systems are provided for moving data objects from a first storage location to a second storage location. One or more data objects may be selected from a first storage location. An identifier of a first type may be assigned to each of the selected data objects, and an identifier of a second type may be assigned to each of the selected data objects. The second type ID may be stored in a second lock object. Systems and methods consistent with the invention may determine whether the second type ID is stored successfully, and upon a successful storage, may store the first type ID in a first lock object. The data object is then stored at a second storage location, the first ID of which is contained in the first lock object. The data object may then be deleted from the first storage location, and the second type ID is deleted from the second lock object after a particular first type ID has been stored in the first lock object.

摘要:
An integrated circuit is combined with a transponder to function either as a voltage or power supply for the transponder by extracting energy out of an electromagnetic field transmitted by a base station or as a detector in the transponder to act as a remote sensor. For this purpose the integrated circuit comprises diode rectifiers. Each of the diode rectifiers has a first and a second service terminal and a reference terminal. In order to reduce a parasitic impedance between the first service terminal and the reference terminal, the first service terminal of at least one rectifier diode is electrically connected to a reference potential such as ground. Parasitic diode characteristics are further reduced by surrounding the respective diode or diodes by an electrical conductor path also connected to the reference potential.
摘要:
In a tire pressure measurement system a display indicating whether a tire (1) has an inadmissible or incorrect tire pressure and which tire (1) has inadequate tire pressure, is only activated when the driver stops to refuel. One or more sensors (6) are located near to the tank for this purpose and these identify a fuel stop.
摘要:
A system for the detection of a pressure drop in a tire comprising a tire air pressure sensor, a tire temperature sensor and an evaluating unit. The evaluating unit converts the measured air pressure values and temperature values into temperature compensated air pressure values and produces an alarm signal when the temporal fluctuation exceeds an air pressure fluctuation threshold value. The evaluating unit decreases the air pressure threshold value with increasing deviation from the measured temperature compensated air pressure value of a predetermined temperature compensated air pressure reference value. At least one further sensor may be provided for measuring a parameter which influences the air pressure in the tire whereby the evaluating unit corrects the measured and, regarding to the production of an alarm signal, evaluated air pressure according to this parameter.

The invention relates to a rotor for a turbomachine, in particular a low-pressure turbine rotor for a gas turbine, having at least one stage, each stage comprising a rotor disk having rotor blades attached to the rotor disk, and the rotor disk of each stage being removably connected either to oppositely situated rotor disks of adjoining stages or to a rotor connection of a rotor shaft by at least one respective attachments. According to the invention, the, or each of the, attachment means extends through the rotor disk of at least one stage, whereby the, or each of the, attachment means is guided with radial play into at least one borehole passing through the respective rotor disk, so that an interior borehole surface is not subjected to load or force.

A method and circuit for wireless data transmission between a base station and one or more transponders is provided in which the base station modulates a carrier signal with a modulation signal and transmits it, in which symbols that are to be transmitted are coded by the base station using sequential delimiters. A value of a particular symbol being determined by the time period between two sequential delimiters, and in which the particular delimiter is generated by changing the modulation signal during a modulation period. Whereby, the modulation signal is preferably a noise signal during the modulation period.
