摘要： A dispersion compensation system includes one or more etalons optically coupled in series. The optical path length is used to achieves the desired dispersion compensation. In one example, at least some of the etalons are tunable in OPL and have a non-tunable front reflective interface. The dispersion compensation system can be tuned, for example to compensate for different amounts of dispersion, different combinations of dispersion offset and dispersion slope and/or manufacturing variations. In another example, the etalons all have a non-tunable front reflective interface. The optical path length is selected to compensate for chromatic dispersion that varies from one wavelength channel to the next.

摘要： A combine having a camera system is disclosed in which pictures of the ground in front of the vehicle are processed to extract the slope and intercept of a characteristic line indicative of the boundary between the cut and uncut portions of the field. A fuzzy logic algorithm compares the slope and intercept using four input membership functions and a single output membership function. If the slope and intercept extracted from the image are deemed acceptable, they are used to navigate the vehicle through the field. If they are not acceptable, the combine continues to use slope and intercept values previously deemed acceptable to guide the vehicle. This process of image data extraction and quality analysis continues repetitively as the combine traverses the field harvesting crops.

摘要： A method of determining noise in a CATV channel, wherein the CATV channel comprises a predetermined frequency band, that employs digital signal processing to isolate the noise signal from an in-service television signal. The method includes an initial step of obtaining a television signal corresponding to a predetermined CATV channel, the television channel comprising a carrier signal modulated by an information signal. Thereafter, the method includes the step of sampling at least a part of the television signal to produce a digital signal segment, said digital signal segment comprising a carrier component, a noise signals component, and an information signal component, wherein said information signal component has a substantially predetermined signal pattern. The method then employs digital signal processing to separate the carrier component from the digital signal segment to produce a baseband signal substantially comprising the information signal and the noise signal. Finally, an estimate of the information signal is obtained and then subtracted from the baseband signal, thereby producing a noise signal estimate.

摘要： An RF circuit for use as a front end for a combined leakage signal detector and signal level monitor includes a shared frequency conversion stage utilized for both leakage signals and signal level monitoring ("SLM") signals. One embodiment of the present invention includes an RF circuit comprising a first RF input, a second RF input, a frequency conversion circuit and a coupling device. The first RF input is operable to receive first signals to be monitored, the first signals being in a first frequency range. The second RF input is operable to receive leakage signals to be detected, the leakage signals also being in a first frequency range. The frequency conversion circuit is operable to convert signals in the first frequency range to signals in a second frequency range, the frequency conversion circuit operable to receive unconverted first signals and unconverted leakage signals and produce output signals therefrom. The output signals produced by the frequency conversion stage have a frequency in the second frequency range. The coupling device alternately connects the first RF input to the frequency conversion circuit and the second RF input to the frequency conversion circuit. The output signal may then be provided to a suitable measurement circuit that performs leakage signal detection or signal level monitoring using known methods.
