  • Patent number: 8769691
    Abstract: 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.

  • Patent number: 7155321
    Abstract: 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.

  • Patent number: 7058396
    Abstract: 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.

  • Publication number: 20060025907
    Abstract: A vehicle information system including a computing system, a vehicle application, an access-layer application, a vehicle-application database, and a communication adapter is provided. The computing system may run an operating system and a plurality of applications. The vehicle application, which is executable by the computing system, may provide policy processing of a parameter received from the access-layer application. The access-layer application has a first interface adapted to communicate with the vehicle application and a second interface adapted to communicate with the operating system. The vehicle-application database may house information for processing the parameter. The communication adapter may pass the at least one parameter between the second interface and the vehicle controller.

  • Publication number: 20050060070
    Abstract: A system, method, and computer program product is provided for remote vehicle diagnostics, telematics, monitoring, configuring, and reprogramming. The system includes an on-board unit disposed on at least one vehicle, an application-service-provider infrastructure, and an interface. The on-board unit is operable to send and receive data corresponding to at least one vehicle operating characteristic. Located on the application-service-provider infrastructure is an application suite. The application suite includes at least one modular application each of which has an associated function that processes said data obtained via the on-board unit. The interface is operable to select from the application suite at least one of the modular applications that will use the associated function to diagnose, monitor, configure, reprogram, and/or obtain telematic information from the at least one vehicle.
