  • Patent number: 6778168
    Abstract: An image display system includes a host system for executing an application program, a display connected to this host system, and an interface for connecting the host system to the display and used to display an image on the display. This interface enables packetized data including ID information to be transferred from the host system to the display. The interface is composed of a first interface for transferring packetized data together with packet order information and a second interface for enabling less data than the capacity of the first interface to be transferred from the display to the host system together with information of a packet transfer error recognized according to the order information.

  • Patent number: 6725332
    Abstract: A storage device and a method for determining the entry with the highest priority in a buffer memory. The method is characterized by the steps of operating a plurality of priority subfilter circuits each of them covering a disjunct subgroup of the total of entries and each selecting the entry with the highest subgroup priority, and selecting the entry associated with the highest priority subgroup. The storage device is able to be allocated and deallocated repeatedly during processing program instructions in a computer system. The storage device is further characterized by an operator for operating a plurality of priority subfilter circuits. Each of priority subfilter circuits covers a disjunct subgroup of the total of entries and each selecting the entry with the highest subgroup priority. The storage device is still further characterized by a selector for selecting the entry associated with the highest priority subgroup.

  • Patent number: 6715104
    Abstract: A system for accessing a memory organized in memorization subsystems or memory blocks, e.g. standard Dual In-line Memory Modules, wherein the words to be stored are split into unitary elements so that several memorization subsystems are used to store one word and its associated Block Error Code (BEC) bits, is disclosed. The system includes a detector to detect a failure within a memorization subsystem. Insulator that are associated to each memorization subsystem insulate the failed memory block, and a new memorization subsystem is accessed in lieu of the failed one thanks to identification device which determine an available unfailed memory block. The user may replace the failed memory block without shutting down the memory device.

  • Patent number: 6669382
    Abstract: A printer including a printing head for performing printing while moving over a printing medium, a gap roller capable of rolling along a direction of moving of the printing head, and a platen bar placed so as to face the printing head and the gap roller. The printer further includes a controller for controlling a pressing force of the platen bar applied to the gap roller according to a printing end position of the printing head on the printing medium.
