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 wireless communication system, comprising: an imaging apparatus; a storage medium attached to the imaging apparatus; and a terminal device, wherein the imaging apparatus comprises: a controller to control operation of the imaging apparatus and to execute transmission/reception of data, wherein the storage medium comprises: a first wireless communication unit; and a control unit to execute transmission/reception of data, wherein the terminal device comprises: a command generating unit to generate a command for controlling the operation of the imaging apparatus; and a second wireless communication unit, wherein: the controller executes a checking process in a predetermined cycle; and when the controller determines that the storage medium has received the command, the controller controls the operation of the imaging apparatus in accordance with the command and transmits an instruction to change operation of the control unit to the storage medium in accordance with the operation of the imaging apparatus.

Wireless communication system

A wireless communication device in a data collection system starts measuring a time when the wireless communication device receives a wireless signal from a data collection device. The wireless communication device changes the wireless channel, transmits a detection signal for detecting the data collection device, and starts measuring a time after transmitting the detection signal when the wireless communication device is unable to receive a next wireless signal from the data collection device even after passage of a predetermined time since the wireless communication device has previously received the wireless signal. The wireless communication device changes the wireless channel to be used, depending on whether the wireless communication device has received a response signal from the data collection device in response to the detection signal within a predetermined time.

Data collection system, data collection device, wireless communication device, and communication method for collecting data

A photographing information management method, which includes: judging whether there is equality between photographing position information added to an image file stored in an external storage medium which is detachably attachable to an imaging apparatus and photographing position information stored in an internal memory of the imaging apparatus; and when it is judged that the two pieces of photographing position information have the equality, displaying an image and the photographing position information of the image file on a display screen of the imaging apparatus.

Apparatus and method for photographing information management

An imager is provided having an imaging sensor, an image processor, and a recorder. The imaging sensor creates an image signal by photographing a subject. The image processor processes the image signal with visual effects processing so as to create image data, and adds metadata to the image data so as to create an image file. The metadata contains post-processing information includes information based on the visual effects process. The recorder stores the image file. The visual effects process is used in processing the image data. The image processor conducting a post process in which more than one visual effects process is carried out, a new image file is created, and the new image file is stored in the recorder. The post-processing information has a post-processing counter and pre-processing information. The post-processing counter indicates the number of times the post process is carried out. The pre-processing information represents the state of a preprocessed image file prior to post processing.

Imager that adds visual effects to an image and records visual effects information in an image file

An image-recording device comprises a recording processor recording a common still image, to which an identical frame number (a folder-number/file-number pair, for example) is attached, on a plurality of recording media, respectively. A plurality of images, to which an identical frame number is attached, are simultaneously indicated on the screen of a monitor. A candidate image is selected, which should be subjected to a predetermined image process such as deletion operation, from the plurality of images indicated on the screen.

Image-recording device

An image-recording device comprises a recording processor that records a common still image on a plurality of recording media, respectively, which are detachably mounted on the image-recording device. A common unique data is recorded together with the still image on the plurality of recording media in a photographing operation, respectively. In a displaying operation for the still image, the unique data is read out from the plurality of recording media. When the read-out unique data coincide with one another, the image-recording device displays record information indicating that the read-out unique data are identical.

A vehicle-control communication system, in which a plurality of control function units such as ECI (engine control) are separated into an I/O processing function and an operation control function, and the I/O processing function for each control function unit comprises I/O processing nodes, while the operation control function is formed as one of the operation control nodes for each of vehicle control groups each obtained by integrating control function units with a relation therebetween into one group. Transmit-receive of information within each of the vehicle control groups is executed via any of first communication lines, while transmit-receive of information between the vehicle control groups is executed via a second communication line.

Vehicle-control communication system

An apparatus for controlling the degree of fiber variations in paper sheet has a formation meter for receiving an image of transmitted light on one side of an area of paper from a light source located on the other side of the area of paper, an image processing computing element for introducing the image from said formation meter for image processing and a fuzzy control unit for calculating and outputting optimum J/W ratio, optimum foil angle, and optimum deflector pushing degree and angle on the basis of results of image processing from said image processing computing element.

Apparatus for controlling the degree of paper fiber variation

A formation control method and apparatus in which an image is emitted from a light source and transmitted through a predetermined area of paper an captured by a camera to be displayed as transmitted light image on a display of an image processing computing element, the transmitted light image displayed on the display being image-analyzed to obtain formation factor for quantification of the formation, J/W ratio and the like being optimized by fuzzy control using membership functions based on said formation factor so as to improve the formation.
