摘要:
The electric rotating machine includes a stator winding constituted of conductor segments each having a pair of in-slot portions and a coil end section projecting from both axial ends of a stator core. The coil end section includes a joint-side end portion having a skew portion intersecting with another one of the conductor segments at an axial end of the stator core. The skew portion is formed with a joint end portion at an extremity thereof, the joint end portion being formed with a conductor exposed portion where an inner conductor is exposed and joined to a conductor exposed portion of another conductor segment. A joint area between the joint end portions and a vicinity thereof are covered by an insulating resin member. The insulating resin member is thicker at a portion covering the conductor exposed portions than at a portion covering other than the conductor exposed portions.

A communication system has a sensor node which is driven by a battery, and which is switched in a predetermined cycle from a sleep mode to an active mode to perform data collection, a base station which transmits and receives data to and from the sensor node by wireless communication, and a monitoring device which transmits and receives data to and from the base station by wireless communication or by wired communication. The base station has a storage portion which stores a command from the monitoring device and a proxy portion which notifies the monitoring device of reception of the command, and which transmits a command stored in the storage portion to the sensor node in response to a request from the sensor node.

A logging system includes a plurality of receiving wireless devices, and a logging device. Each receiving wireless device receives a communication content of a target wireless device by using a corresponding channel. Each receiving wireless device outputs a log that shows a communication status of the corresponding channel. A logging device collects the log that is output from each of the plurality of receiving wireless devices.

There is provided a wireless communication device which transmits data to destination nodes by time division multiplexing. The device includes: a storage section including a transmission queue region that stores unsent data therein; a communication controller including: a communication situation evaluating section configured to evaluate a communication situation of each of the destination nodes; and a communication slot controller configure to: allocate, in the plurality of communication slots, communication slots for data transmission to the respective destination nodes, retransmission slots for retransmission of the unsent data, and auxiliary retransmission slots for retransmission of the unsent data subjected to a specified destination node, the specified destination node being determined based on the communication situation; and allocate the respective unsent data to a corresponding one of the retransmission slots and the auxiliary retransmission slots based on a given condition.
摘要:
An apparatus for managing network objects in a heterogeneous network, a network management system and a network management apparatus are provided. The apparatus includes processor that receives, using a first protocol communicated using a communications protocol, a network management request to manage a network object in the heterogeneous network, and that transmits, according to a second protocol that is different than the first protocol, the network management request to the network object network management interface is provided.
摘要:
In a time synchronization system between wireless nodes, a first wireless node broadcasts a neighbor search packet, adjacent wireless nodes receive the neighbor search packet and then returns an adjacent response packet, the first wireless node selects the mediating wireless node based on the adjacent response packet and then transmits a mediating request packet to the mediating wireless node, the mediating wireless node receives the mediating request packet and then broadcasts a time record request packet, the first wireless node receives the time record request packet and then records reception time, the adjacent wireless nodes receive the time record request packet and then records reception time, the higher-level adjacent wireless node transmits a time notification packet containing the reception time to the first wireless node, and the first wireless node calculates the difference between the recorded reception time and the reception time contained in the time notification packet and then adds the difference to current time.
