Title: Device and method for deciding operation plan
Inventor: IWAMA KENZO
IPC: G05B13/02
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To provide an operation plan decision device for a robot allowed to execute required movement even when a peripheral environment is slightly changed. SOLUTION: When two abstracted environment group data driving instructions are mutually identical, only those that have common data for other than the driving instruction are extracted (step S37). The processing (step S37) is repeated until two driving instructions are different from each other (step S38). Thus, an operation plan generated at first collects abstracted environment group data obtained by abstracting sensor values until the driving instructions are changed. On the other hand, at an operation changing point the generated abstracted environment group data are used as they are. In this manner during the execution of the same operation, an operation plan capable of allowing the robot to execute desired movement even for a slight environmental change can be generated by abstracting the shape of the surroundings.

Title: Spread spectrum communication system, its transmitter- receiver, communication method
Inventor: ICHIKAWA TORU
IPC: H04J13/00
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To solve problems that many spread codes are consumed while an initial synchronization acquisition time is made the same degree as the case with no multiplexing in the case of providing a different spread code to multiplex channels, and spread code generators whose number is equal to the number of multiplexed channels are required for a transmitter and a receiver respectively. SOLUTION: The same spread code sequence is assigned to each of multiplexed channels while only the phase of the sequence is changed differently at a transmitter side. A memory 4 at a receiver side stores a correlation calculated by a digital correlator 3 and a CPU 5 reads this correlation to control the phase of the spread code generated from a spread code generator 2. Thus, the time required to acquire initial synchronization is decreased at the same speed as the case with assignment of different spread codes to each channel. Since one kind of the spread code generator is enough to save the spread codes and the size of the transmitter and the receiver can be decreased.
