A communication device is provided in a wireless multi-hop network. The communication device receives a sequence number, a divided time acquired by dividing a time width allocated for transmitting detected usage data by a division number, and the division number. The communication device calculates a remainder by dividing the received sequence number by the division number and calculates a transmission offset time based on the remainder and the divided time. The communication device transmits the usage data based on the calculated transmission offset time.

Communication device and communication method

A data communication apparatus forms a mesh network together with at least one gateway includes a frame generating unit and a frame transferring unit. The frame generating unit generates a meter data frame to transmit to a gateway. The meter data frame is a frame including meter data. The frame transferring unit transfers the meter data frame received from another data communication apparatus. The meter data frame is addressed to the gateway. The frame generating unit transmits the meter data frame to which number of alternate routing that indicates number of allowable transmission attempts from a data communication apparatus adjacent to a destination gateway of the meter data frame to the gateway is added. The frame transferring unit changes the number of alternate routing added thereto to a value smaller by 1 than a value that has been set and transits the meter data frame to another data communication apparatus.

Data communication apparatus, data communication system, and data communication method

A communication device is included in an ad hoc network in a reactive routing scheme. The communication device includes a receiving unit, a selecting unit, and a transfer control unit. The receiving unit receives a route request frame including overall quality information on routes through which the route request frame has passed. The selecting unit selects a route request frame to be transferred to another communication device based on the quality information, from the route request frames received by the receiving unit through a plurality of routes. The transfer control unit transfers the route request frame selected by the selecting unit to the another communication device, and discards the route request frame when a quality value indicated by the quality information of the route request frame is smaller than a predetermined reference value.

Communication device and communication control method

A software update system includes an administration server, a wireless communication terminal, and a wireless-communication key station. The wireless communication terminal is configured to be connected to the administration server through a communication network. The a wireless-communication key station is configured to be positioned between the administration server and the wireless communication terminal, and to perform processing of distributing software of an update object transmitted from the administration server to the wireless communication terminal.

The disclosure is of a spin-cast reel wherein a spool is slidably and rotatably carried on an axial body extension. A rotary shaft carrying the rotor is coaxially mounted in the extension and a drag control knob is mounted at the back of the reel body, also on the axis of the rotary shaft. The drag control knob carries a nut that moves along a threaded rod which, in turn, forces the legs of a U-shaped member against a disc spring to apply a drag force against the side of the spool. Thus, the drag can be controlled from the rear of the reel and on the axis of the spool and rotor.
