  • Publication number: 20080301673
    Abstract: An in-vehicle terminal (101) is provided, which has a function ensuring that computer resource secured by a virtual machine (1a1) or a virtual machine (1b1) is controlled within a limit value of the computer resource that is allocated to the corresponding virtual machine, or a function which is capable of executing multiple virtual machines appropriately. When the virtual machine (1a1) or the virtual machine (1b1) requests securing the computer resource, the in-vehicle terminal (101) requests the OS (143) to secure computer resource in response to the request, if the requested resource is lower than the limit value of the computer resource that is allocated to the corresponding virtual machine.

  • Publication number: 20060154692
    Abstract: A personal digital assistant comprises a loss detector to detect a lost state and a value information retainer for retaining a value assessment index, which are numerical values indicating data values. When a lost state is detected by the loss detector, a data recovery sequence is determined based on the data values and data is transmitted to another terminal. In determining the recovery sequence, electrical energy required for data transmission is calculated using a power consumption table and the remaining battery power level measured by a remaining battery power level meter is referenced.

  • Patent number: 5819521
    Abstract: A steel cord for reinforcing a rubber product has a multilayer structure consisting of two or more layers including a core, or a structure consisting of seven or more strands twisted in the same direction at the same pitch. In the steel cord, at least one of three strands that are successively adjacent to one another or that are in mutual contact is formed of two filaments that are paired substantially parallel to each other. The direction of pairing the two filaments of each strand is substantially the same over the entire length of the cord. Each of the remaining strands is formed of a single filament.
