A method for referencing a polyphase stepper motor by monitoring the current step response in at least one driven phase is presented. The coil current step response is compared to past step responses in order to determine when an increase in or maximum load is present. A combination of step to step variance, step response variance from mean current magnitude, and average current magnitude variance, as well as other measures can be combined to create an algorithm output. The output is compared to a pre-determined threshold and if the value is greater than the threshold, the motor is commanded to halt its position, which remains magnetically synchronous. This position is then used as a reference point to zero, or to home the motor.

A digital watermark embedding system generates a watermarked image by providing one or more specific regions in an image, each specific region including two or more base regions symmetric with respect to the centroid, and by embedding a watermark in the image while avoiding the specific region. Further, a digital watermark detecting system detects a watermark in a region other than the specific region, by detecting the shape of the specific region in which no watermark is embedded, calculating the centroid position of the specific region as a centroid, and correcting geometric transformation of the image based on the location in the image that corresponds to one or more calculated centroids.

A method of determining the position of a mobile device using a model. The model comprises a graph comprising a set of vertices and a set of edges between the vertices, and one or more feature functions that take as input one or more vertices of the graph and a set of observations for the device, and return a feature value. The model is constructed by obtaining a map of the geographical area, constructing the graph using the map, wherein the vertices of the graph correspond to areas of the map, and two vertices are joined by an edge when the areas corresponding to the vertices are adjacent and can be travelled between by a device, and building the one or more feature functions using the graph, wherein the feature value of the one or more feature functions indicates the extent to which the observations support the device being positioned in the areas corresponding to the one or more vertices of the graph. The method then comprises the steps of: obtaining a set of observations from the sensors of the device; determining the trajectory for the device that optimises the values given by the feature functions given for the set of observations; and determining the position of the device to be the end point of the trajectory.

A current perpendicular to plane dual giant magnetoresistive sensor (dual CPP GMR sensor) that prevents spin torque noise while having high dR/R performance. The sensor has a design that maximizes the GMR effect (dR/R) by providing a pinned layer structure that maximizes the positive GMR contribution of the AP2 layer (or magnetic layer closest to the spacer layer) while minimizing the negative GMR contribution of the AP1 layer (or layer furthest from the spacer layer). The pinned layer structure includes an AP1 layer that includes a thin CoFe layer that is exchange coupled with an IrMn or IrMnCr AFM layer and has two or more Co layers with a spin blocking layer sandwiched between them. The use of the Co layers and the spin blocking layer in the AP1 layer minimizes the negative contribution of the AP1 layer. The AP2 layer has a plurality of CoFe layers with nano-layers such as Cu sandwiched between the CoFe layers. The nano-layers increase the already strong GMR effect provided by the CoFe layers, increasing the positive GMR effect from the AP2 layer.

The proposed modular transformer concept is based on a production process in two steps, which separates the fabrication of the turns from the assembly of the transformer, and thus combines automation potential and flexibility. Both the high-voltage winding and the low-voltage winding are composed of effectively two-dimensional spiral conductor tracks (21,22). These conductor tracks can be produced in a computer-aided manner, and then just need to be stacked and electrically connected. Special insulator layers (11,12) are inserted between the conductor tracks and on the one hand bear the weight while on the other hand providing optimum electrical insulation, so that the distances between the high-voltage and low-voltage conductor tracks can be reduced, and the losses in the conductors as well as the short-circuit impedance of the winding can be decreased.
