    Abstract: A surgical navigation system employs an endoscope (30) and an imaging unit (80). The endoscope (30) include an electromagnetic tracker (40) within a working channel of endoscope (30) for generating electromagnetic sensing signals indicative of one or more poses of the endoscope (30) within an anatomical region, and an endoscopic camera (50) within an imaging channel of the endoscope (30) for generating endoscopic images of the anatomical region. The imaging unit (80) executes an intraoperative calibration of the electromagnetic tracker (40) and the endoscopic camera (50) as a function of an image registration between the preoperative scan image of a calibration site within the anatomical region and one or more endoscopic images of the calibration site within the anatomical region.

    Abstract: A voltage controlled delay line (VCDL) for measuring the maximum speed of a chip includes a first input configured to receive a reference clock signal, a first output configured to output an output clock signal, and a second input configured to receive a phase error signal representing a phase delay between the reference and output clock signals. A register stores a delay code applied by the VCDL to the reference clock signal to delay the reference clock signal to generate the output clock signal. The delay code is adjusted according to the phase error signal until the phase delay is equal to a predetermined value. A second output is coupled to an interface that reads the delay code from the register and outputs the delay code to automated testing equipment when the phase delay is equal to the predetermined value. The outputted delay code corresponds to the maximum chip speed.

    Abstract: This invention provides methods for reduction of mercury emissions from cement plants. In one method, a powdered activated carbon sorbent is injected into a gas stream of a cement plant at one or more points after the kiln and before the particulate collection device of the cement plant. Also provided is an apparatus for decreasing emissions from a cement plant, which apparatus comprises two or more beds in a series comprising a first bed which is a moving bed, and one or more remaining beds which are fixed beds, each fixed bed comprising at least one sorbent which is able to absorb at least one of mercury, hydro-carbons, and hydrochloric acid. Another method for reducing emissions from a cement plant employs the apparatus just described.

    Abstract: An identification method and apparatus of confusable character are provided. The method involves: the detected character image is identified to gain the initial character information which is corresponding to the character image; the step change times of the corresponding external outline of the character image are counted if the initial character information is the confusable character; the final character information corresponding to the character image is confirmed according to the step change times; The final character information of the character image can be known conveniently according to the step change times, therefore the corresponding correct character information of the character image can be identified more precisely. The possibility of wrong identification of the character image because of the appearing confusable character can be reduced, and the identification precision rate of the confusable character can be improved.
