20140098045 | METHOD AND SYSTEM FOR TOUCH SHAPE RECOGNITION, RELATED SCREEN APPARATUS, AND COMPUTER PROGRAM PRODUCT - An embodiment of a method of recognizing finger detection data in a detection data map produced by a touch screen includes converting the data from the x, y, z space into a three-descriptor space including: a first coordinate representative of the number of intensity peaks in the map, a second coordinate representative of the number of nodes (i.e., pixels) absorbed under one or more of the intensity peaks. A third coordinate may be selected as the angular coefficient or slope of a piecewise-linear approximating function passing through points having the numbers of nodes absorbed under the intensity peaks ordered in decreasing order over said intensity peaks, which permits singling out finger data with respect to non-finger data over the whole of the touch screen. The third coordinate may be also selected as an adjacency value representative of the extent the intensity peaks are adjacent to one another, which permits singling out finger data produced over a portion of the touch screen with respect to non-finger data produced over another portion of the touch screen. | 04-10-2014 |

20110291286 | ELECTRONIC DEVICE AND METHOD FOR CONNECTING A DIE TO A CONNECTION TERMINAL - An electronic device including a die-pad area, a die fixed to the die-pad area, a connection terminal, and a ribbon of conductive material. The ribbon is electrically connected to the die and to the connection terminal, and has a prevalent dimension along a first axis, a width, measured along a second axis, which is transverse to the first axis, and a thickness, which is negligible with respect to the width; the ribbon moreover has a cross section that defines a concave geometrical shape. | 12-01-2011 |

20150076712 | ELECTRONIC DEVICE WITH BIMETALLIC INTERFACE ELEMENT FOR WIRE BONDING - An electronic device includes a chip with an integrated electronic component and a terminal made of a first metal material. The device further includes a lead made of a second metal material different from the first metal material. A bonding wire made of a selected one of the first and second metal materials has opposite ends coupled with the terminal and the lead. An interface element having a first layer made of a selected one of the first and second metal materials and a second layer made of an unselected one of the first and second metal materials has the first layer coupled with the bonding wire and the second layer coupled with a component, wherein the component is ether the terminal or the lead. | 03-19-2015 |
