Abstract: Watermarking of audio signals intends to manipulate the audio signal in a way that the changes in the audio content cannot be recognised by the human auditory system. The watermark data are decoded from the received watermarked audio signal by correlation with corresponding candidate reference sequences. One or more of the sync symbols are embedded twice in the watermark data frame in the encoder. Thereafter a circular correlation is calculated instead of a standard correlation.

Abstract: A method of identifying an agent which modulates 2-oxoglutarate dependent oxygenase activity, the method comprising contacting a 2-oxoglutarate dependent oxygenase and a test agent in the presence of a substrate comprising one or more ankyrin repeat, or fragment thereof, in conditions under which the substrate is hydroxylated in the absence of the test agent; and determining hydroxylation of the substrate.

Abstract: A method and accompanying apparatus that allows high concentrations of hydrogen peroxide for tooth whitening by use of an aerosol spray.

Abstract: Many watermarking systems make use of correlation for calculating a detection metric, which means that several reference patterns are generated at encoder side and one or more of them are embedded inside the content signal, dependent on the message to be embedded. To decode the embedded message, it is necessary to discover which reference pattern was embedded at encoder side. This is determined by correlating the known reference patterns with the content signal. A watermark detector decides, depending on the size of the correlation result values, whether or not a given pseudo-random sequence was embedded. However, this does not provide correct decisions if watermarked audio is emitted by a loudspeaker and then captured with a microphone. According to the invention, it is taken advantage of the received signal echoes instead of treating them as noise.

Abstract: A method for concentrating and/or positioning and/or separating particles or cells comprises placing a liquid medium containing the particles and/or cells over a surface having an electrode array associated with the surface, applying an alternating voltage to the electrode array to create an electric field above the surface within the medium to repel the particles or cells from the electrode array and thereby levitate the particles or cells above the surface, within the medium, by negative dielectrophoresis, and heating the liquid medium so as to cause convection currents to circulate within the medium which concentrate or relocate the levitated cells within the medium. Apparatus for concentrating and/or positioning and/or separating particles or cells are also disclosed.

Abstract: An oral hygiene system includes a whitening solution, and applicator, and a rinse. The whitening solution includes a concentration of hydrogen peroxide for whitening teeth within a predetermined period of time without the use of a mouthpiece. The applicator may include a resilient head capable of conforming to the topography of a tooth surface, and may be used for applying gelatinous whitening solution to teeth. The rinse is configured to reduce organic sulfides in the mouth, and may include zinc acetate. The whitening solution may be applied to the teeth for predetermined amount of time, for example, less than about 10 minutes. The solution may then be rinsed off with the rinse. The procedure may then be repeated periodically, for example, daily until the desired shade of whiteness is achieved.

A cycloid power component and a correspondingly formed blocking component are in mutual engagement in said machine. The difference in the number of teeth between both components is one. The volume of the working chambers (16) thus created attains a maximum and a minimum level at each rotation owing to the synchronous rotation of said power component and blocking component.

Abstract: Disclosed is a position system and method for correcting the position of a workpiece during a manufacturing process. The system includes a light generating means for projecting a light beam onto the top surface of the workpiece at a predetermined angle and a video capturing means for detecting the light received by the workpiece. The light projected on the workpiece is scanned to determine the deviation direction and the deviation amount from a predetermined reference point, then the position of the work piece is adjusted based on a positional relationship between a digital image of the projected light on the surface of said workpiece and the predetermined reference image.

According to the invention, the missile is redirected into an essentially horizontal cruising and seeking phase after completing an essentially vertical start phase. During said cruising and seeking phase, the missile scans the terrain ahead of it using the seeking head, whereupon an approaching phase which is directed in an essentially downward direction follows after the finally ensues head locks onto an identified target. An external reconnaissance system in an appropriate aircraft and/or spacecraft such as in a helicopter, a drone or in a satellite receives information for guiding the missile which is transmitted to the same.
