Abstract: The invention relates to a method, and a corresponding system, capable to check whether genuine SERS or SERRS taggants having a unique characteristic surface enhancement scattering feature are present or not on a machine-readable marking applied on a value document by using a Raman spectrometer adapted to perform a Raman Spectroscopy analysis of the marking. The method according to the invention allows a reliable and fast detection of a presence of the SERS/SERRS taggants, and is particularly suitable for checking authenticity of value documents, e.g. such as banknotes, moving with respect to the Raman spectrometer with a given speed, and possibly with a high speed, or briefly exposed to the Raman spectrometer.

Abstract: Methodology for detecting and monitoring the propagation of a volume of liquefied material underground without measuring the resistivity of the ground. Liquefied material is charged by injecting current through electrically-conducting member in contact with the material to form a spatial distribution of electric potential underground. Measuring time-dependent change of such spatial distribution caused by movement of liquefied material and associated with propagation of a Gaussian surface of electrical charge associated with the outer surface and/or the front of the volume is detected with a system of electrodes to determine a time of arrival of liquefied material to target location.

Abstract: A directional filter for processing full-tensor gradiometer data is described. The filter processes input data using a method comprising receiving geophysical data collected based on characteristics of geographic features in an environment, and applying a directional filter to the received geophysical data in a first instance so as to provide first filtered data. A filtering direction of the directional filter is determined based on properties in the received geophysical data. The method also includes updating the filtering direction based on properties in the first filtered data, applying the directional filter to the received geophysical data in a subsequent instance using the updated filtering direction so as to provide subsequent filtered data, and based on the updated filtering direction having a subsequent update less than a threshold, outputting directionally filtered data. The subsequent update is determined due to properties in the subsequent filtered data output from the subsequent instance.

Abstract: In a method of defining an animation of a virtual object, during which values for attributes of the virtual object are updated at each of a series of time points, a user specifies a structure representing the update that includes a plurality of items and one or more connections between respective items. Each item represents a respective operation. Each connection represents that data output by the operation represented by one item is input to the operation represented by the connected item. The user specifies that the structure comprises one or more items in a predetermined category associated with a predetermined process that may be executed at most a predetermined number of times at each time point. An item belongs to the predetermined category if performing the respective operation represented by that item requires execution of the predetermined process. One or more rules are applied.

Abstract: A full mouth toothbrush for simultaneously brushing the facial, lingual, occlusal and incisal surfaces of all the maxillary and mandibular teeth is provided. The full mouth toothbrush can include a handle, a power source, a motor assembly, and a drive assembly. The full mouth toothbrush can further include a mouthpiece configured to collectively contact multiple surfaces of multiple teeth simultaneously that brushes and, thus, cleans the teeth and gums.

Abstract: A device and method for brushing all surfaces of all of a user's teeth simultaneously. The device comprises bristle strip surfaces that envelope all of a user's teeth, the bristle strips comprising bristle bundles that scrub all surfaces of a user's teeth due to a reciprocating motion of the bristle strips. To use the device, a user inserts the toothbrush bristle strips into their mouth so to engage the user's teeth. A power source, motor, and drive assembly are utilized to cause the bristles to reciprocate, cleaning all a user's teeth surfaces simultaneously.

Abstract: In a method of producing a particulate electrocatalyst composition, a precursor medium comprising at least a first metal precursor, a liquid vehicle, and a substrate precursor to substrate particles is atomized into precursor droplets. The droplets are then heated to a reaction temperature of not greater than 700° C. to form composite particles comprising said first metal at least partly in an oxide form dispersed on said substrate particles. The composite particles are then collected and are heated at a first treatment temperature no greater than 250° C. in the presence of a reducing atmosphere to at least partly convert said oxide form to the metal.

Abstract: A phosphor composition comprises a host lattice, a dopant and a decay modifying component different from the dopant and the host lattice and effective to alter the rate of decay of the radiation emitted by the phosphor composition in response to excitation by photons of a given energy. The decay modifying component is added to the phosphor composition in a predetermined amount between 1 and 10,000 parts per million of the composition. By varying the amount of the decay modifying component added to the phosphor composition, it is possible to produce a set of phosphor compositions with different, controlled rates of decay of the radiation emitted by the compositions.

Abstract: An accelerometer and rate sensor package to aid gravity gradiometers is provided. The accelerometer and rate sensor package is mounted directly on or within a gravity gradiometer instrument (GGI). Outputs from the sensors can be used to reduce unwanted noise due to angular rotational rates, angular accelerations and linear accelerations that may be coupled to the GGI. Since the sensor assembly is directly mounted on or within the GGI, the sensor assembly is coupled to the GGI and senses the acceleration and angular rates as seen by the GGI. Thus, outputs from the GGI can be corrected more effectively using the sensor assembly's outputs.
