摘要： An apparatus for removing a ghost component which disturbs a picture signal by means of a ghost canceling reference signal included therein. The reference signal is extracted from the picture signal and judged as to whether it has a specific level in a reference time interval. The extracted reference siganl is also judged as to whether a color burst signal is canceled. If both judgements are positive, a judgement signal is generated which allows the extracted signal to be examined how it is disturbed by the ghost component. In response to the examination, the ghost component is removed from the picture signal.

摘要： A transversal filter filters an input video signal with a filtering characteristic determined by tap gains. A row of error signals are generated on the basis of a difference between a ghost cancel reference signal in the input video signal and a predetermined reference signal. A magnification setting circuit sets a first magnification in accordance with the row of the error signals. A weight setting circuit converts an output signal from the magnification setting circuit into weighting data and feeding the weighting data into the transversal filter as the tap gains. The weight setting circuit functions to correct the first magnification into a second magnification in accordance with row numbers denoting the respective error signals in the row.

摘要： A state estimation value indicating a battery state is successively calculated from time to time according to a battery model capable of dynamically estimating the internal state of the secondary battery by using an inspection value of a sensor group indicating the secondary battery behavior. By using the sate estimation value at each moment estimated by the battery model expression at each predetermined cycle, an I/O-enabled time is predicted when a predetermined power is continuously inputted (charged) or outputted (discharged) from the current moment. A load operation instruction of the secondary battery is set so as to avoid overcharge and over-discharge of the secondary battery according to the operation request to the load and by considering the predicted characteristics between input/output power and input/output-allowed time.

摘要： When it is determined by a determining portion (54) that the SOC of a first auxiliary power storage device (BB1) has reached a first lower limit value (TL), a switching control portion (56) generates a switching signal (SW) to switch from the first auxiliary power storage device (BB1) to the second auxiliary power storage device (BB2). A SOC estimating portion (52) measures the OCV for the first auxiliary power storage device (BB1), for which it has been determined that the SOC has reached the first lower limit value (TL) and has thus been disconnected, and estimates the SOC of that first auxiliary power storage device (BB1), based on that measured OCV. If the estimated SOC is higher than the first lower limit value (TL), after the SOC of the second auxiliary power storage device (BB2) has reached the first lower limit value (TL), the switching control portion (56) generates a switching signal (SW) to switch from the second auxiliary power storage device (BB2) to the first auxiliary storage device (BB1).

摘要： A battery state estimating unit estimates an internal state of a secondary battery according to a battery model equation in every arithmetic cycle, and calculates an SOC based on a result of the estimation. A parameter characteristic map stores a characteristic map based on a result of actual measurement performed in an initial state (in a new state) on a parameter diffusion coefficient and a DC resistance in the battery model equation. The parameter change rate estimating unit estimates a DC resistance change rate represented by a ratio of a present DC resistance with respect to a new-state parameter value by parameter identification based on the battery model equation, using battery data measured by sensors as well as the new-state parameter value of the DC resistance corresponding to the present battery state and read from the parameter characteristic map.
