Abstract: There is provided a method for estimating a center frequency of a wavelet. The method comprises performing a sequence of measurements to obtain a sequence of samples, wherein each measurement comprises obtaining a respective sample of a convolution of a first wavelet, whose center frequency is to be estimated, and a second wavelet generated respectively by a first second wavelet generator. The second wavelet has a duration smaller than a middle portion of substantially constant center frequency of the first wavelet. A timing offset between the first and second wavelet is varied between the measurements such that each sample represents a respective point of the convolution, and such that the sequence of samples represents a portion of substantially constant center frequency of the convolution. Un-wrapped phase values are obtained by unwrapping a sequence of instantaneous phase values estimated from the sequence of samples.

Abstract: A method for performing radar measurements, comprising first through fourth measurements, each including: generating a radar pulse, transmitting the radar pulse towards a radar target, generating a reference pulse, receiving a signal comprising a reflection of the radar pulse after being reflected, mixing the received signal with the reference pulse, and integrating the mixing product; wherein generating the reference pulse is delayed with respect to generating the radar pulse by a first, second, third and fourth delay time, respectively, wherein a difference between the second and first delay time, between the third and second delay time, and between the fourth and third delay time, each corresponds to a quarter of a wavelength of the radar pulses; and determining a first and second value representing a difference between the integrated mixing product of the first and third radar measurements, and between the integrated mixing product of the second and fourth radar measurements, respectively.

Abstract: The present invention relates to a process for improved surface sizing in the manufacture of paper or board products. According to the present invention, an aqueous dispersion of microfibrillated cellulose (MFC), starch and pigments or fillers is treated by jet cooking and then used for surface sizing in a process for manufacturing a paper or board product.

Abstract: Methods of determining whether an environment is suitable or acceptable for performing a three-dimensional (3D) scan are provided. The methods may include performing one or more checks on captured image data of the environment, wherein performing each of the one or more checks comprises determining whether the environment satisfies a respective criterion. The method may further include determining that the environment is suitable or unsuitable for performing the 3D scan based on a result of each performed check. Determining that the environment is suitable for performing the 3D scan may include determining that the environment satisfies each of the respective criteria of the performed one or more checks. Determining that the environment is unsuitable for performing the 3D scan may include determining that the environment does not satisfy at least one criterion of the performed one or more checks. Related devices and computer program products are also provided.

Abstract: A method of reducing the proportion of oxygen in an at least partly formed package before product is filled into the package in a filling station in a filling machine, where the package comprises a tube-shaped blank of packaging material, the blank being closed in a first end and open in a second end. The method involves, during transport of the package to the filling station from an immediately preceding station in the filling machine, passing the package beneath a supply means for inert gas, and when the package passes the supply means generating a gas pulse in a direction down into the package. An apparatus is provided for reducing the method into practice.
