Abstract: The present invention relates to a method for estimating a distance between nodes of an LPWA network. A first node (a second node resp.) successively transmits a narrow band signal at a plurality of carrier frequencies (421). The second (the first resp.) node receives the transmitted signals and demodulates them into baseband (422). Complex values representative of a forward-backward function of the transmission channel between two nodes are obtained (423) from the baseband demodulated signals. These complex values are then provided to a previously supervisingly trained neural network (425), the neural network giving an estimation of the distance separating the first node and the second node. The present invention also relates to a method for estimating the position of a node in an LPWA network using said distance estimation method.

Abstract: A method may include responding to a query to retrieve data from a database by identifying a plurality of query execution plans. An overall robustness value may be determined for each query execution plan. The overall robustness value of a query execution plan may correspond to a sum of individual robustness values for each operator included in the query execution plan. Each operator may have an individual robustness value that corresponds to a first change in a total cost of a query execution plan including the operator relative to a second change in an output cardinality of the operator. One of the plurality of query execution plans may be selected based on the overall robustness value of each of the plurality of query execution plans. The query may be executed by performing a sequence of operators included in the selected one of the plurality of query execution plan.

Abstract: A loudspeaker overload protection circuit and method receives at a compressor a signal representing the estimated loudspeaker power consumption; receives at the compressor a signal representing the nominal power of the loudspeaker; receives at the compressor an input audio signal from the signal source and supplying with the compressor an output audio signal to the loudspeaker; estimates from the output audio signal, (a) signal(s) that represent(s) the voltage and/or current supplied to the loudspeaker and a parameter that represents the ohmic resistance of the loudspeaker the power consumed by the loudspeaker; supplies a signal representing the estimated loudspeaker power consumption to the compressor; and attenuates the input audio signal when the signal representing the estimated loudspeaker power consumption exceeds the signal representing the nominal power of the loudspeaker.

Abstract: A system automatically mixes a first audio signal and a second audio signal. The system includes a correlator that determines whether the first signal and the second signal are correlated according to a predetermined correlation criterion. If the predetermined correlation criterion is fulfilled, the correlator determines whether the first and the second signal are delayed. A delay circuit compensates for the delay between the first signal and the second signal. A mixer mixes the first signal and the second signal that includes a compensation.

Abstract: The invention relates to a method for detecting a rollover situation in such a way that a restraint, such as belt tighteners or head airbags, can be released at the right time during rollover. The signals that pertain to several sensors and detect transitional and rotational movements are detected, connected to one another and evaluated.

Abstract: Antioxidants or antioxidant-contaming preparations for producing compositions are used for eliminating halitosis or preventing the formation of halitosis. According to the invention, the antioxidants used can be all antioxidants which are suitable or customary for oral hygiene applications. In particular, vitamins and coenzyme come into consideration as antioxidants. Those which also come into consideration are, for example, amino acids, imidazoles, peptides, fatty acids, metal compounds and derivatives of these compounds (for example salts, esters, ethers, sugars, nucleotides, nucleosides).

Abstract: A method for determining an absolute rotational angle of an object that is rotating about an approximately horizontal rotational axis, includes steps of: determining a change in a rotational angle of the object occurring during a time interval; determining an acceleration component acting in a direction of a vertical axis of the object; determining a change, occurring during the time interval, in the acceleration component acting in the direction of the vertical axis of the object; and calculating the absolute rotational angle of the object from the change in the rotational angle and the change in the acceleration component acting in the direction of the vertical axis of the object. A device constructed to perform the method does not necessarily require expensive, high-stability acceleration sensors. Sensors of a simple design can be used instead.
