    • A multi-touch system is disclosed that compares finger arrangements at the beginning of multi-touch gestures and discriminates between neutral- and spread-hand performances. Gestures by the neutral- and spread-hand versions of each chord are then mapped to separate, but intuitively related cursor functions or sets of commands. Less-frequently performed functions and commands are typically assigned to the spread-hand chord, since spreading the hand from neutral takes deliberate effort. With these neutral and spread distinctions, a two-handed gesture set can be packed into a one-handed touch surface, or for two-handed touch surfaces, twice as many intuitively customizable gesture command sets can be accomodated.
    • 公开了一种多点触摸系统,其比较多点触摸手势开始时的手指布置并区分中性和手势表现。 然后将每个和弦的中性和扩展版本的手势映射到单独但直观相关的游标功能或命令集。 经常执行的功能和命令通常被分配到扩展手和弦,因为从中性手伸出手来刻意地努力。 凭借这些中性和差异性的区别,双手手势集可以包装成单手触摸表面,或双手触摸表面,可以容纳两倍的直观可定制的手势命令集。

    • A defect detection system includes a video camera with defect detection circuits for detecting defects in video signals being outputted by corresponding sections of an array sensor such as a TDI CCD two-dimensional array sensor. Each defect detection circuit includes a subtraction circuit for subtracting a prior stored pixel from an incoming pixel to generate a difference. Comparators compare the difference with positive and negative limits defining an acceptable range of difference values. The prior stored pixel is updated to the succeeding pixel only when the difference value is acceptable. Memories store the defect pixels from the respective detection circuits along with X-coordinates and end of line bits. The memories are sequentially read up to their end of line bits, and the defect pixel values along with coordinates expanded to include section indicating bits are transferred from the camera to further processing facilities.
    • 缺陷检测系统包括具有用于检测诸如TDI CCD二维阵列传感器的阵列传感器的相应部分输出的视频信号中的缺陷的缺陷检测电路的摄像机。 每个缺陷检测电路包括用于从输入像素中减去先前存储的像素以产生差值的减法电路。 比较者将差异与定义可接受的差值范围的正和负极限进行比较。 仅当差值可接受时,先前存储的像素被更新为后续像素。 存储器存储来自相应检测电路的缺陷像素以及X坐标和行尾位。 存储器被顺序读取到它们的行末端位置,并且缺陷像素值以及被扩展以包括指示位的部分的位置从相机传送到另外的处理设施。
