A printing apparatus has a cartridge attachment section including a terminal block having apparatus-side terminals disposed on its inclined surface, and a printing material supply pipe. Among the apparatus-side terminals, one apparatus-side ground terminal located on their center in Y direction is protruded to a greater height than the other plural apparatus-side terminals. A printing material cartridge has a circuit board, a printing material supply port, and a board mount portion that is inclined at an acute angle relative to a plane extended from an opening face of the printing material supply port. The circuit board is arranged such that one cartridge-side terminal on the circuit board comes into contact with the apparatus-side ground terminal prior to the other cartridge-side terminals in the process of attachment of the printing material cartridge to the cartridge attachment section. This arrangement enables the printing material cartridge to be attached in an adequate correct orientation or alignment to the printing apparatus. This arrangement also reduces the possibility of failure caused by application of a high voltage to the circuitry of the printing material cartridge.

The present invention relates to a silicon-on-insulator (SOI) substrate, a method for fabricating the SOI substrate and a SOI MOSFET using the SOI substrate to easily migrate the design applied to a conventional bulk silicon substrate to the SOI design and to remove a floating body effect. The SOI substrate includes a mono-silicon substrate, a buried oxide layer formed over the surface of the mono-silicon substrate, and a thin mono-silicon layer formed over the surface of the buried oxide layer. Conductive layers are formed at through holes of the buried oxide layer positioned between the predetermined regions of the thin layer and the substrate for body contacts. Therefore, additional layout spaces are not needed for body contacts and the constant body contact resistance can allow the conventional circuit design applied to the bulk silicon substrate to be migrated to the circuit design applied to the SOI substrate without any modifications. Also, a variety of operational failures caused by the floating effect can be eliminated in the SOI substrate. As a consequence, additional effort is not required for designing or verifying the circuit of the present invention, so as to make it possible to construct a highly efficient, but low power consuming system.

Mobile Edge Computing (MEC) has the advantages of high bandwidth and low latency and has attracted extensive attention in the study of next generation of mobile networks by providing service environment and computing power at the edge of mobile networks. The invention discloses a vehicle task unloading and user mobility prediction and edge cache fusion policy in a vehicle networking environment. An MEC-based unloading framework is built. Tasks can be unloaded to an MEC server for vehicle-to-infrastructure (V2I) communications or can be unloaded to an adjacent vehicle for vehicle-to-vehicle (V2V) communications. Considering task backhaul failure caused by link disconnection caused by user mobility, the Kalman filter algorithm is used to predict link connection estimation, and a user can select a stable service node during task request and task collection. Cache decisions are made before the service node first returns a task to a request vehicle. Access latency, traffic load and networkcost can be significantly reduced through content cache.

Disclosed herein is a method for Wireless Local Area Network (WLAN) User Equipment (UE) selection of a Packet Data Gateway (PDG). When the WLAN UE fails to access, the PDG returns a message containing the failure cause value to the WLAN UE that has sent the request such that the WLAN UE could perform different operations according to the specific failure cause value in the message to select a PDG. For example, the WLAN UE may request DNS again to obtain the IP address of the PDG in a home network by parsing in connection with a requested service, or the WLAN UE may first subscribe to the service before re-performing the operation of selecting a PDG, or the WLAN UE may re-select a PDG with another parsed IP address and send a connection request thereto. As a result, the process of WLAN UE asking DNS to re-direct to the home network to select PDG is left out when possible, unnecessary signaling is avoided, and the network resources are saved.

A high availability database system, subject to a failure causing data corruption in the active server system, may recover valid data prior to the corruption, and use the protected and recovered data to effect a failover. At the time T1 when a stand-by computer system detects the occurrence of a failure, a pair split is done to the data area to protect the data area time T0, just before the occurrence of the failure, and another pair split is done to the log area at the time, where the log area is corrupted or a time T3, where the failover is to take effect without corrupting data, to protect the log area containing data at a given time between time TO and time T3. By using the data and log areas thus protected, the stand-by computer system may take over valid data and log areas of the given time to perform a failover.

A queuing server is used for reliable message transport, where one subsystem desires to execute one or more ordered operations asynchronously. Messages are sent to the queue in groups, which may have one or more messages. Messages within a particular group are processed in a predetermined order. Optionally, groups of messages can marked as correlated such that all groups within a particular correlation can be processed in a predetermined order. A message can be stored in a SQL database table until processing of that message is complete. The receiving side of the message system can be scaled across multiple machines and/or across available resources of any given machine. The system can handle “disaster” scenarios on both the sending side (i.e. the sending machine crashes in the middle of sending a group), and the receiving side (i.e., a power failure causes a reboot in at least one of the receiving machines).
