摘要： PROBLEM TO BE SOLVED: To provide an electronic key registration system capable of ensuring security of electronic key registration.SOLUTION: For example, if the ECU of a vehicle 1 gets out of order, the ECU (replaced ECU 31) having got out of order needs to be replaced with a new ECU (replacing ECU 32). Key registration on the replacing ECU 32 is completed by switching the replacing ECU 32 to a registration mode for an electronic key 2 by a registration tool 20, and inserting an electronic key 2 used for the replaced ECU 31 into the key cylinder 43 of the vehicle 1 and rotating the electronic key to an ON position. At this time, the replacing ECU 32 reads an electronic key ID and a before-replacement on-vehicle unit ID out of the electronic key 2 by radio, and transmits the electronic key ID, the before-replacement on-vehicle unit ID, and an after-replacement on-board unit ID as ID information Did to a center 21. The center 21 performs ID collation with the ID information Did received from the registration tool 20, and allows electronic key registration when the ID collation is successful.

摘要： PROBLEM TO BE SOLVED: To provide a signal processor of a time-division multiplex adaptive array-antenna in which power loss can be minimized when changing over a switch, and deterioration of reception characteristics can be made less likely to occur.SOLUTION: In a time-division multiplex adaptive array-antenna 1, one reception circuit 4 is shared by multiple antennas 2.
