Title: System and method for utilizing checksum to recover data
Inventor: BRIAN HONANG
IPC: G06F12/16
Filed: 2002-01-10
Abstract: PROBLEM TO BE SOLVED: To recover a data value without temporarily regulating a write request to overwrite the data value of a checksum set. SOLUTION: A system (115) for storing and retrieving data utilizes a plurality of memory units (155a to 155e) having memory locations for storing data values. A checksum of a plurality of the data values in a particular checksum set is maintained in one of the memory locations. One of the plurality of data values can be recovered by combining each of the remaining plurality of data values with the checksum. After retrieving one of the plurality of data values during the data recovery process, steps are taken to ensure that any further attempts to access the location of the retrieved data value do not cause an update to the checksum, Therefore, the locations storing the data values of the checksum set may be accessed during the data recovery process without causing errors to the data recovery process.

Filed: 2002-01-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a head for percussion instruments of good sound quality which permits formation of rough surfaces approximately uniform in the sizes of ruggedness by adopting chemical etching in place of mechanical polishing.  <P>SOLUTION: The head 1 for a drum is composed of a synthetic resin film 2, such as a PET (polyethylene terephthalate) film and its front and rear surfaces are subjected to chemical etching. The front and rear surfaces of the film 2 are therefore formed to the rough surfaces having the approximately uniform ruggedness 6. When the film 2 is the PET film, an aqueous caustic alkali solution is used for the chemical etching of the film 2. When the PET film is immersed into the aqueous caustic alkali solution, hydrolysis progresses from the fiber surfaces and the front and rear surfaces are successively decomposed, by which the ruggedness 6 is produced and the matt-like surfaces are obtained.  <P>COPYRIGHT: (C)2003,JPO

Title: Method of informing error occurring during execution of program in electronic terminal
Inventor: HENON ALEXANDRE
IPC: G06F11/22
Filed: 2002-01-22
Abstract: PROBLEM TO BE SOLVED: To report on error occurring during the execution of a program in a terminal and to remove the possible error, which can occur in the electronic terminal during the execution of the program. SOLUTION: This method proposes the method of reporting the error occurring during the execution of the program in the electronic terminal. When an error occurs during the execution of the program, data items related to the error are automatically processed, and recorded in an error memory of the terminal. The contents of the error memory are transmitted to a remote device (for example, a server, belonging to a manufacturer of the terminal) periodically, or when the error memory is full, or when it is requested by the server. This transmission is preferably done by the WAP type or i-mode type internet electronic message. This method can be applied in any electronic terminal provided with a communicating means which is suitable for transmitting the contents of the memory.
