An information processing system automatically identifies the page of a book, notebook, flip chart, writing pad, or the like. The encoded element may be used to label any desired item, such as drugs or medicines, or other pharmaceutical or health care products or cosmetics. Performance improvements include removing the effects of variations in winding resistance, independently adjusting a pick-off voltage, reducing the effects of transformer leakage inductance, providing DC isolation between circuits and increasing the signal to noise ratio at the receiver. A substantially enclosed boathouse may form the structure when the structure has only a lower level. The present invention relates in particular to novel specific substituted indazoles exhibiting kinase-inhibiting activity, having therapeutic activity, in particlar in oncology.
