Abstract: The method is for metamorphically transforming from a frist shape to a second shape in a video graphics system. The method comprises the steps of identifying elements common to the first and second shapes and identifying a first set of segments of elements in the first shape unrelated to the second shape. Each segment is delimited by a pair of common elements and a second set of segments of elements are identified in the second shape unrelated to the first shape. Each segment is delimited by a pair of common elements and the common elements are interpolated from the first shape to the second shape. Each segment of the first set of segments is interpolated to the segment of the second set delimited by the same pair of common elements.

Title: Controlled frequency heart pacemaker - has transducer sensing acidity of blood and providing signal compared with reference to vary pacemaker frequency accordingly
Inventor: RISANI ROBERTO
IPC: A61N/
Filed: 1978-11-30
Granted: 1985-09-28
Abstract: The pacemaker includes an impedance matching stage receiving on its input the electrical signal produced by a linear transducer providing a signal varying according to the pH of the blood. This stage may also amplify this signal to about one volt. The signal is then fed to one input of a comparator whose second input receives a reference voltage. The output of the comparator comprises a signal whose voltage has a value proportional to the difference between the inputs received. This signal is fed to a limiting matching circuit which provides an output (U) which is fed to a variable frequency pacemaker, whose frequency is proportional to the value of the signal (U). If the pH of the blood falls as a result of additional physical activity, the output signal rises increasing the frequency of the pacemaker.

Title: Clothing material artificial ageing
Inventor: FRANCO RENZO
IPC: D06M/
Filed: 1986-03-14
Granted: 1988-03-23
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Abstract: A fibrous composition for absorbent pads which, in addition to cellulose fibres, also contains first and second synthetic polymeric materials. At least the second polymeric material is constituted by synthetic fibres which have a higher melting point than that of the first polymeric material. The fibrous mixture is formed into the desired shape, for example, an absorbent body for disposable sanitary products, by pneumatic means. The absorbent body thus formed is then heat-treated to a temperature higher than the melting point of the first polymeric material but lower than that of the second polymeric material for a period of time so as to melt the first polymeric material and form bonding points or bridges (5) between at least the synthetic fibres (4) which have not melted and which constitute the second polymeric material. The absorbent body is cooled to a temperature such that the first polymeric material sets, bonding at least the synthetic fibres together so as to form a framework containing the cellulose fibres (6).

Filed: 2021-07-30
Abstract: Method for formation of the diffractive optical element consisting of plurality surface microstructuresABSTRACTThe invention relates to the formation of diffractive optical elements in a photopolymer, where the formed elements can be used in the splitting of a light beam. The polymeric diffractive optical element is formed by treating the photopolymer layer with a defocused femtosecond laser beam, and the diameter of the affected spot is ≤20µm. In the laser exposed area of the photopolymer, a photopolymerization reaction is initiated, which makes the affected area insoluble in an organic solvent. By scanning the laser beam in the photopolymer, an array of microstructures is formed. The inner arrangement of microstructures determines the diffractive properties of the optical element. The optical element can also be used as a generator of the Bessel-type beam array in the near field.Išradimas yra susijęs su difrakcinių optinių elementų formavimu fotopolimere, kur suformuoti elementai gali būti panaudoti šviesos pluoštų skaidyme.
