Title: Radio access communication system
Inventor: SUDA YUKINORI
IPC: H04W84/12
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To search a nearby radio base station using different radio frequency without generating packet loss even while a radio terminal on which only one transmitter/receiver is mounted communicates with a radio base station in a radio access communication system for asynchronously performing packet transmission. SOLUTION: The radio terminal 50 informs a radio base station 20a of a fact that the terminal 50 enters a communication suppressed state such as a power save mode by transmitting a state transition information packet 150 to the radio base station 20a when the terminal 50 detects the degradation of communication. The packet to be received at the state is held in the radio base station 20a, when an ACK signal 310 is received from the radio base station 20a, changes setting of a receiver to a radio channel different from the one used in the communication with the radio base station 20a and searches the other radio base station.

Title: Method and apparatus for creating and verifying public key certificate
Inventor: KUMAGAI YOKO
IPC: H04L9/08
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for creating and verifying public key certificates that can issue a public key certificate by which an EE (End Entity) clearly confirms certificated contents by the public key certificate and the range of the responsibilities between an IA (Issuing Authority) and an RA (Registration Authority) and that allows the EE receiving the public key certificate to confirm the effective range of the certificate even when the management subject of the IA differs from that of the RA. SOLUTION: The RA confirms and investigates a user when registering the user of an EE apparatus and generates a signature of the RA on the basis of the information obtained through the confirmation and the investigation. The IA creates the public key certificated including the signature of the RA on request from the RA and signs the signature of the IA to the entire public key certificate. The EE receiving the public key certificate issued in this way verifies the signatures of the RA and the IA so as to confirm that the RA surely warrants (signs) the information confirmed by the RA, and confirms the effective range of the certificate.

Filed: 2001-11-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for a display device maintenance in which temperature rise abnormality of the device that is an outdoor type and has a heat generating display section is reliably detected.  <P>SOLUTION: When a temperature sensor 2 detects temperature rise abnormality, a control section 3 reduces the luminance of a display section 4 by one or few steps and discriminates to determine whether the abnormality has been eliminated using the signals of the temperature sensor. When the abnormality is eliminated, it is judged that, even though the section 3 has detected temperature rise abnormality, the temperature rise has not been caused by the failure of the display device but by the temperature rise of outdoor air or the like and no abnormality detection is transmitted. When the temperature rise abnormality is not eliminated, the luminance is further reduced by one or few steps. When the temperature rise abnormality is not eliminated even though the luminance is reduced to a prescribed level, it is determined that the temperature rise abnormality is caused by the temperature rise not due to outdoor air but due to the failure of the display device and a warning is given to the outside.  <P>COPYRIGHT: (C)2003,JPO
