  • Patent number: 8255878
    Abstract: Via an internal bus 69, a host emulation unit 61 of a control procedure unit 60 loads a program under development into, and sends program execution control commands to, a program under development execution unit 70 which includes an engine processor. In response to these program execution control commands, the program under development execution unit 70 performs execution starting, stopping, pausing, or resumption of the program under development. On the other hand, execution mode setting information for the program under development is sent from an execution mode setting unit 62 of the control procedure unit 60 via the internal bus 69 to the program under development execution unit 70, in response to commands from the user. Based upon this execution mode setting information, the program execution operation by the engine processor is controlled by the program under development execution unit 70.

  • Patent number: 8154551
    Abstract: When a character input is necessary during an execution of an engine application 39k in an engine section, a character input processing request section 65 of the engine section issues a character input processing request FRQ depending on a request from the engine application 39k. After receiving the character input processing request, a character input processing section 61 of a host section carries out a character input processing, and notifies a character input processing result to the engine section. In the engine section which has received the character input processing result, characters according to the character input processing result are displayed by using character font data in the engine section. As a result, it is possible to make an apparatus structure compact, as well as to improve a convenience for a user.

    Abstract: The present invention enables accurate detection of risks from an electronic mail message. In a mail inspection unit, an information extraction section extracts text and a mail address from electronic mail accumulated in a journal DB, and a text normalization section normalizes the text. A sort-information saving section generates text sort information according to the score obtained from a sorting engine, and stores it in a mail-management-information storage section. A personal-information saving section extracts personal information from a personal-information storage section according to the mail address, and stores it in the mail-management-information storage section. Finally, a risk-level determination section compares the information stored in the mail-management-information storage section with the information stored in a category-information storage section to determine the risk level of the electronic mail.

  • Patent number: 8024495
    Abstract: A communication data controller is provided which is capable of correctly retransmitting transmission data even if a block of the transmission data exceeding a FIFO (First-In First-Out) memory is written in an overwriting manner to the FIFO memory. The memory stores transmission data to be transmitted to a communication device. Transmission data stored in the memory is written and read to and from the FIFO memory by a CPU (Central Processing Unit). A DMAC (Direct Memory Access Controller) driver, when a request for retransmission of a block is made in the case where the block of transmission data exceeding a capacity of the FIFO memory is written to the FIFO memory, drives the DMAC and transfers the block being stored in the memory to the communication data controller.

  • Patent number: 7925367
    Abstract: The invention proposes a system that interrupts a processing associated with an ADC having low priority when an ADC processing cannot catch up with ADR by an ADC alone that is not under execution but uses an ADC for an ADR having high priority. To preferentially execute ADR/ADC having high priority, the invention employs an algorithm for serially selecting ADR/ADC in the order of higher processing capacity (in the order of greater numerical values in the expression by a DPH unit) from among ADR/ADCs that have the lowest priority, no matter whether the ADR/DC is now under execution or not.

  • Patent number: 7881558
    Abstract: A method which, while displacing the field-of-view, allows the image in a target area to be acquired without degradations such as out-of-focus of the image. Plural pieces of images are acquired before and after a target area while displacing the field-of-view. Next, these images are grouped into groups each of which includes several pieces of images, and integrated images on each group basis are created. Moreover, a relational expression is calculated which holds between image displacement quantity calculated by comparing the integrated images with each other and the number of the photographed pieces of images. Furthermore, image displacement quantities between the acquired plural pieces of images are calculated from this relational expression. Finally, these images are corrected by the amounts of these displacement quantities, then being integrated. This process allows reconfiguration of the image in the target area.
