Patent number: 8769691Abstract: A server access log includes data records each describing a previous query regarding a suspect computer file of a client computer. Each record includes the CRC code for the suspect computer file, the result of the malware analysis performed on the backend server and other attributes and values. The log is analyzed to retrieve relevant attributes and values from each record. Key attributes and values are generated such as region and continuous query. All CRC codes are grouped according to attribute values. Each group is analyzed to determine the network traffic associated with downloading the entire group to all user computers and the network traffic associated with not downloading the group but responding to future malware queries regarding CRC codes in the group. CRC codes are removed from each group if necessary. CRC code-result pairs for each group are downloaded to all user computers as a pre-fetch cache.Type: GrantFiled: February 14, 2011Date of Patent: July 1, 2014Assignee: Trend Micro, Inc.Inventors: Gary Hsueh, Jeff Kuo, Sam Chang, Shako Ho, Norman Wang

Patent number: 7155321Abstract: A remote vehicle diagnostics, monitoring, configuration and reprogramming tool is provided. The system includes a fleet of vehicles equipped with wireless mobile communications means that enable fleet managers to remotely diagnose, monitor and reprogram vehicles in their fleet via an Internet Web-based browser environment. Each vehicle within the fleet is equipped with a smart device that is coupled to the data bus within each vehicle. Date commands relating to the vehicle's parameters (e.g., diagnostic parameters such as max road speed, engine RPM, coolant temperature, air inlet temperature, etc.) are sent and received using satellite and terrestrial wireless communications technology. The invention allows users to remotely perform total fleet logistics and eliminates (or reduces) the need to physically bring fleet vehicles to a repair, maintenance or configuration facility.Type: GrantFiled: August 6, 2001Date of Patent: December 26, 2006Assignee: IDSC Holdings LLCInventors: William Bromley, Brian R.

Patent number: 7058396Abstract: A calling method using a short message transmission on a calendar group is utilized to send a coded calendar in a man machine interface of a mobile device from this mobile device to another mobile device through a short message transmission. A short message is decoded by using a same decoding method used for the transmitter mobile device to transfer into a corresponding calendar state in the receiver mobile device after it receives the short message in order to inform a meeting participant or a group member a meeting appointment, meeting time or other messages. And, a function such as an alarm time prompting can be set for a receiver side to mention the receiver through a same manner. Therefore, not only calendar-receiving mobility can be increased, but also expenses can be saved because informing meeting participants by telephone is unnecessary if the method according to the present invention is used.Type: GrantFiled: August 19, 2002Date of Patent: June 6, 2006Assignee: Lite-On Technology CorporationInventors: Vincent Wu, Sam Chang

Publication number: 20030236940Abstract: A Method for repeatedly recording a program in a flash memory is utilized to record a revised application program into a planned flash memory after the program is edited. The flash memory comprises a fixed program zone used to store never-revised fixed programs, an application program zone used to store revisable application programs and a callback function entrance point zone used to store an entrance point matrix. The starting address values of all callback functions in the application zone called by the fixed programs are stored in the entrance point zone. Therefore, only the program codes of the callback entrance point zone and the application program zone parts need to be recorded when the flash memory is recorded. Consequently, recording efficiency can be upgraded and program maintenance time can be reduced.Type: ApplicationFiled: July 24, 2002Publication date: December 25, 2003Applicant: GVC CORPORATIONInventors: Vincent Wu, Sam Chang
