Digital watermarking is adapted for the variable data printing. A reference signal serves as a proxy for optimizing the embedding a watermark in a host image to be printed. Using the reference signal, embedding parameters are generated, which are a function of constraints such as visual quality and robustness of the machine readable data. Adjustments needed to embed a unique payload in each printed piece are generated using the embedding parameters. These adjustments are stored in a manner that enables them to be efficiently obtained and applied within the RIP or press during operation of the press. Various other methods, system configurations and applications are also detailed.

An apparatus receives a document image and digital-watermark information and determines an embedding capacity based on a number of the letters in the document image.

The present invention introduces a method for processing multichannel measurement data achieved especially in MEG and EEG measurements. The method uses a signal space separation (SSS) method and the orthogonality of lead fields in order to calculate linear transformation from physical measurement channels to virtual channels. The geometry related to the measurement arrangement is dissipated and the number of virtual channels is clearly lower than the number of physical sensors. The concept of total information can be applied for such transformed measurement data due to orthogonality. The method offers simplified post-processing of the biomagnetic data, such as for source modelling. The total information can also be interpreted as a robust quantity describing the physiological state of a patient.

An illuminable basketball rim assembly includes an anchor member that has a hollow cavity filled with a weight agent. A support pole is coupled to the anchor member and extends upwardly therefrom, and has a distal end positioned anterior to the anchor member. A rim section is positioned at the distal end of the support pole. A mechanism illuminates the rim section and the support pole when an external force is applied to the rim section. A mechanism maintains the support pole at a stable and equilibrium position such that the distal end of the support pole is prohibited from displacing downwardly beyond a predefined height.

In sophisticated semiconductor devices, the initial strain component of a globally strained semiconductor layer may be substantially preserved during the formation of shallow trench isolations by using a rigid mask material, which may efficiently avoid or reduce a deformation of the semiconductor islands upon patterning the isolation trenches. Consequently, selected regions with high internal stress levels may be provided, irrespective of the height-to-length aspect ratio, which may limit the application of globally strained semiconductor layers in conventional approaches. Furthermore, in some illustrative embodiments, active regions of substantially relaxed strain state or of inverse strain type may be provided in addition to the highly strained active regions, thereby enabling an efficient process strategy for forming complementary transistors.
