Abstract: A displacement of a pedestrian is determined from his or her accelerations by detecting accelerations which is substantially non vertical, determining a characteristic feature in the detected accelerations correlated with a step frequency, determining the displacement on the basis of said determined characteristic. The acceleration data can be submitted to waveform analysis to determine an actualized time interval of an occurring feature, such a maximum values, from which it is determined whether the actualized time period falls within determined limit values. The currently detected characteristic feature is then determined as corresponding to a displacement step if the actualized time period falls within said determined limit value. By using non-vertical acceleration measurements, the invention can make it possible to distinguish between forward, backward, left and right stepping movements and take these into account for the navigation.

Abstract: The invention concerns an assembly comprising: (a) means for determining the intensity of a plurality of electromagnetic signals, (b) a correlator for correlating or autocorrelating said signals, (c) means for continuously calculating the variance and/or the standard deviation of said signals. It also concerns a method for analysing the intensity of a plurality of electromagnetic radiations scattered and/or emitted from solid, fluid or gaseous samples.

Abstract: Method for manufacturing a plurality of pyroelectric sensors by forming a thin pyroelectric film or layer on one face of a silicon wafer or substrate, wherein electric polarization of this film is provided between lower and upper electrodes defining pixels forming these sensors. In order to protect the wafer in the event of a short-circuit between two electrodes of a pixel, resistors are arranged in series with the lower or upper electrodes by connecting these electrodes to each other by subsets in order to carry out the electric polarization. Once this polarization has been carried out, the electric connections connecting the upper or lower electrodes are removed to allow each pixel to supply an elementary electric signal when the sensor is operating. In order to minimize the risk of short-circuits and in order to reduce the stray capacity of the electrodes, the upper and lower electrodes of the pixels are structured.

Abstract: A method of separating isotopes from polyatomic molecules, in particular 13C from trifluoromethane HCF3, by applying to the polyatomic molecules in the gas phase two infrared laser beams of different frequencies. The first laser has a frequency appropriate to excite a low overtone transition of a light atom stretch vibration and produce vibrationally pre-excited molecules enriched in the desired isotopes, for instance 13C. The second laser has a frequency and energy fluence to selectively induce dissociation of the vibrationally pre-excited molecules by infrared multiphoton excitation.

Abstract: A high molecular weight water soluble acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepared by a process in which a small quantity of a chain branching agent is added to the polymerization reaction mixture continuously or stepwise while the monomers are polymerized. The polymer is useful in solid/liquid separations such as flocculants and coagulants in wastewater treatment applications, and as thickening agents.

Abstract: A method for on-line monitoring and testing the behavior of middleware based, distributed application software during run-time of such software is disclosed. In order to automatize the monitoring of the behavior of the application software, the monitoring method comprises: defining events capturing the behavior of the software execution, the events being based on an abstraction of the application software, the abstraction being provided by middleware; using code generating means and an instrumentation technique for automatically adding code to the implementation of the software code suitable for generating traces suitable to be sent to an observer, the information carried by the added code including information on the order of occurrence of the events and on the application software part location where each event occurs; and using a monitoring mechanism based on sending of trace reports to the observer, which ensures or takes into account the time order of the reported traces.

Abstract: Fluorescent protein expressing cells with very high fluorescence are described as well as a method to obtain such cells. The fluorescence of such cells can be as high as about 1000 times the auto-fluorescence of the respective host cell. Due to the high fluorescence, said cells are very suitable tools in the development, surveillance and/or optimization of production processes, for selection of culture media and process parameters and for the determination of cell growth and the detection, quantification and monitoring of biomass.

Abstract: A non-volatile random access memory (NVRAM) of the type with magnetoresistive memory elements (1) connected by sets of non-intersecting conductor sense lines (3, 4) which define the address of each memory element (1) and are connectable to a magnetic write/read recording unit. The memory elements are a plurality of magnetoresistive submicron dots or wires (1) embedded in a membrane (2) through which the submicron dots or wires extend. The sets of non-intersecting conductor sense lines (3, 4) are connected to the opposite ends of the submicron dots or wires (1) on opposite sides of the membrane.

Abstract: Methods are proposed for visually evenly spacing of two successive characters taking into account outline shape modifications induced by character grid-fitting. Visually even spacing of characters is obtained by converting the geometric space between two characters into its visually perceived equivalent space. Converting between geometric and visually perceived spaces requires transformations applied to the character outlines for smoothing out the character borders and replacing them by virtual borders which represent the boundaries of the perceived intercharacter space. The optimal visual distance between the origins of two successive characters is obtained by requiring the characters to have a perceived visual space equal or close to an ideal perceived visual space called ideal optical intercharacter space extracted from by design optimally spaced character pairs such as "nn" for lower-case characters and "HH" for capital letters.
