摘要:
An onboard equipment network system comprises a radar core device, a GPS core device, an echo sounder core device and a sonar core device and display devices which are connected to a network through a hub. Each core device includes a detecting section or a positioning section, as well as a control section, a power supply section and a data transmitter for transmitting detecting signals or positioning signals, while each display device includes a command section for transmitting command data to the individual core devices for setting their operating conditions and a display section for displaying image data received from the individual core devices. The command data is transmitted using Transmission Control Protocol (TCP) while the image data is transmitted using User Datagram Protocol (UDP).

摘要:
A method is disclosed for setting a master node of a ring network that has adjacently connected nodes situated on rightward and leftward lines of a bidirectional transmission channel. The method includes the steps of: counting the number of nodes interposed between a designated node and each node other than the designated node on the rightward and leftward lines of the bidirectional transmission channel; and setting one of the nodes as the master node. The master node satisfies a relation of, NHC_L=NHC_R or NHC_L=NHC_R-1, wherein NHC_L is the number of interposed nodes counted from the leftward line, and NHC_R is the number of interposed nodes counted from the rightward line.

A reception apparatus is configured to receive data including a plurality of packets each of which has information on a time point when the packet is generated; to extract a terminal packet which is a packet included in the data received and which has information on a time point which is nearest to a current time point; and to control an operation clock by comparing the information on the time point included in the terminal packet with information on an elapsed time obtained by adding information on a time point, which is included in a terminal packet of preceding data, to an elapsed time from when the preceding data is received to the current time point.

A low-molecular-weight polysulfated hyaluronic acid derivative useful for treatment of an allergic disease. An agent for treatment of an allergic disease selected from pollinosis, allergic rhinitis, allergic conjunctivitis, atopic dermatitis, and asthma, represented by the following general formula (IA) or (IB); wherein n represents a number of 0 to 15; R's each independently represent a hydrogen atom or an SO3H group etc.
摘要:
A reconfigurable integrated circuit device which is dynamically constructed to be an arbitrary operation status based on a configuration data, has a plurality of clusters including operation processor elements, a memory processor element, and an inter-processor element switch group for connecting the elements in an arbitrary status; an inter-cluster switch group for constructing data paths between the clusters in an arbitrary status; and an external memory bus. A direct memory access control section, for executing the data transfer between the memory processor element and the external memory by direct memory access responding to an access request from the memory processor elements of the plurality of clusters, is further provided.
