Title: Vertical synchronizing signal generator
Inventor: AKIYAMA TAKAAKI
IPC: H04N5/06
Filed: 2007-12-13
Abstract: <P>PROBLEM TO BE SOLVED: To prevent generation of erroneous vertical synchronizing signals even when detecting erroneous vertical synchronizing pulses by a noise state while non-standard video signals are input.  <P>SOLUTION: In a noise detection circuit 12, whether or not there is noise in the vertical synchronizing pulse period of input video signals PS is detected, and noise detection signals S12 are generated when there is the noise. A frame cycle counter 14 counts the timing to detect the vertical synchronizing signal next. A frame cycle detection circuit 15 examines the interval (cycle) of vertical synchronization and generates a frame cycle MAX value S15 only in the state without the noise. Thus, even when erroneously detecting the vertical synchronizing pulses temporarily when the non-standard video signals PS are input, the frame cycle MAX value S15 is not updated. Further, since normality in a synchornization stability detection circuit 17 can not be examined, loading is not applied to the frame cycle counter 18.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To prevent the occurrence of Null due to composition of received signals in GPS positioning using a plurality of antennas.  <P>SOLUTION: An airframe 1 has an A antenna 2, a B antenna 3, and a C antenna 4 installed on the outer circumference thereof and connected to an A receiver 5, a B receiver 6, and a C receiver 7, respectively. The receivers output an A pseudo distance 11, a B pseudo distance 12, and a C pseudo distance 13 as observed values, respectively. These pseudo distances are used for positioning calculation by a positioning calculation device 14. It is assumed here that the position vectors of the antennas 2 to 4 can be approximated by the mean vector (e.g., the center position vector of the airframe). Then, the number of unknown parameters to be calculated by the positioning calculation device 14 is six, i.e., the total of the elements of the mean vector and the errors in time of the receivers. A result 15 of positioning is thereby obtained with use of a method of least squares if there are six or more linearly independent pseudo distances observed from the receivers 5 to 7.  <P>COPYRIGHT: (C)2009,JPO&INPIT
