  • Measuring device for a flame
    Patent number: 6676404
    Abstract: A flame measuring device, in particular for use in a regulating device for a burner, includes an ionization electrode which is arranged in a flame region of the burner. An ac voltage is applied to the ionization electrode whereby a dc voltage component is superimposed on an ionization current that flows through a resistor connected to the ionization electrode. The flame region influences the ac voltage and the dc voltage at a blocking capacitor unequally, and allows an ac voltage component to be separated from the dc voltage component by way of a first means. The separated ac voltage component can be compared to a separated-off dc voltage component by way of a second means in order to produce a pulse width-modulated signal.

  • Method of control and control structure for the movement control, pre-control and fine interpolation of objects in a speed controller clock which is faster than the position controller clock
    Patent number: 6677721
    Abstract: The invention makes it possible to execute the pre-control and the fine interpolation in the drive (A) in the fast drive clock (tDR) with a slower path pre-setting in the clock (tNC) of the NC. For this purpose, in each NC clock (tNC) a setpoint speed value (nNC*) and the P gain (kP) of the NC position controller (L_NC) and the desired axle speed (nNC) and the average axle speed (nNCMW) during the last NC position controller clock are transferred from the NC to the drive. From this information, polynomial segments of the third degree are in each case generated on the drive side, valid for the duration of an NC position controller clock (tNC). They are constructed in such a way that the speed at the polynomial transitions is constant. A variable component of the position polynomial is determined as the fine position component xF, with which the setpoint position values are finely interpolated in the drive.

  • Valve including a recirculation chamber
    Patent number: 6675572
    Abstract: A method of diverting flow with a valve through a first filter and a second filter to purify exhaust gas with at least one of the filters and to regenerate at least one of the filters with the exhaust gas. Positioning the valve in a first operative position purifies the exhaust gas with the first filter and regenerates the second filter with the exhaust gas. Positioning the valve in a second operative position that is different that the first operative position purifies the exhaust gas with the second filter and regenerates the first filter with the exhaust gas. The method can be achieved by a valve for an exhaust system that including a body and a flow inhibitor. The body defines a volume and has a first inlet, a second inlet, a recirculation chamber, and an outlet chamber in fluid communication with the volume.

  • Two dimensional array switching for beamforming in a volume
    Patent number: 6676602
    Abstract: Methods and systems for electronically scanning within a three dimensional volume while minimizing the number of system channels and associated cables connecting a two-dimensional array of elements to an ultrasound system are provided. An array of semiconductor or micro-machined switches electronically interconnect various elements of the two-dimensional array. Elements associated with a substantially same time delay are connected together as a macro element, reducing the number of independent elements to be connected to beamforming or system channels. To beam form in the desired direction, the macro elements are configured as a phased array or along substantially straight lines in at least two dimensions (i.e. along the face of the two-dimensional transducer). Such macro elements allow transmission and reception along beams that are at an angle other than normal to the two-dimensional transducer array.

    Abstract: A method for protecting an item of software, wherein at least one challenge means is associated with said protected item of software, and at least one response means accesses one private keying material. The challenge means has no access to said private keying material. The response means proves to the challenge means that the response means has access to the private keying material using an asymmetric probabilistic proof, e.g., zero knowledge proof. The challenge means validates this proof using the public keying material that corresponds to the response means' private keying material.

  • Method and device for radio transmission
    Patent number: 6678262
    Abstract: The invention proposes a method and an apparatus for the radio transmission of user data, arranged in data words of a defined length, in time-division multiplex frames having active time slots in which data are transmitted and inactive time slots in which no data are transmitted. The user data are stored temporarily in a memory at a first data rate, and are read out from the memory and converted into the time-division multiplex frames at a second, greater data rate. During the time period from the beginning of an active time slot to the beginning of the subsequent active time slot, n (n=a whole number ≧1) data words of the user data are thereby respectively stored. By synchronizing the storing and the reading out of the user data, these data can be transmitted with the smallest possible delay in an arbitrarily selected time slot of the time-division multiplex frame.

    Abstract: A gas turbine with axially mutually displaceable guide parts that compensates for differing amounts of thermal expansion, comprising guide parts which can be displaced with respect to one another in the axial direction and enclose a funnel-like gas duct from outside. In order to optimize a rotor blade tip gap, at least one of the funnel-like guide parts under control by means of a motor can be displaced. As a result of the axial displacement, because of the funnel-like shape of the guide parts, the width of the rotor blade tip gap is changed.
