Title: Control method and apparatus for free-running mobile unit
Inventor: KATSURA SEIICHIRO
IPC: G05D1/02
Filed: 2002-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To enable performing appropriate avoidance actions by creating a movement route for a mobile unit in response to movements of obstacles even when there exist obstacles in motion.  <P>SOLUTION: An obstacle sensor 3 attached on a ceiling surface detects sequentially positions of an obstacle 2 to transfer to a control device 10. The control device 10 creates a probability potential field indicating a probability of existence of obstacles and adds a gradient headed to a target position in the potential field. The control device 10 then searches a route headed to the target position according to the gradient of the potential field added the gradient and moves a mobile unit 1 along the searched route. So that the potential field is created, it is possible to predict future motion of the obstacles in the motion and avoid the obstacles. And data from the sensor 3 is processed in a probabilistic way, so that it is possible to acquire the probability of existence of the obstacles at the next time without being influenced on fluctuations of the data from the sensor 3.  <P>COPYRIGHT: (C)2003,JPO

Title: Information processing device and method, recording medium and program
Inventor: HAMADA TOSHIMICHI
IPC: H04N19/44
Filed: 2002-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a reproduced image from being disturbed even when synchronous systems are changed.  <P>SOLUTION: When a transmission system is reproduced, a coefficient k of an amplifier 22 is defined as a prescribed value of zero or more. In this case, a PLL is performed at the speed of response corresponding to the magnitude of the coefficient k, and a reference clock synchronizing with a clock at encoding is outputted. When a storage system is reproduced, the coefficient is defined as a value zero. In this case, a reference clock of a default frequency of a VCXO 25 is outputted from a PLL circuit 13. Since the reference clocks in the transmission system reproduction and the storage system reproduction in the present invention are generated from a clock of one VCXO 25 in either case, the continuity of a reference clock and a synchronizing signal is maintained even when a reproduction mode is changed and synchronous systems are switched. Thus, the image without any disturbance can be displayed.  <P>COPYRIGHT: (C)2003,JPO
