摘要:
In an electrophotographic apparatus, densities of toner images of a light reference mark and a dark reference mark are detected by a density sensor, and input voltages such as an illumination power source voltage and an electrostatic charge voltage are varied by small values on the basis of a difference between detected densities and an aimed density, the small values are determined on the basis of a predetermined qualitative model. Subsequently, a line width of the toner image of a reference mark having a striped pattern is detected by a line width sensor and a developer bias voltage is varied by a small value in a similar manner as mentioned above.

In a control network system of household electric appliances, particularly, an each introduction of a household electric appliance thereto does not cause a change in the means of acquiring operation data by a controller, and the electric power consumption of a controller is made less.A home network system is simplified and made efficient.As a means for the above, an accessible device in a common manner to household electric appliances is incorporated into a controller by object processing using communications middlewares, and a device for linked operations is incorporated into household electric appliances. Then, it is noted that each household electric appliance needs a specific kind of another appliance and operation data thereof.

When a common key is updated to a new common key, it is possible to prevent the generation of a period during which not all the general communication apparatuses are enabled to make mutual communications using encrypted data while at the same time reducing the memory consumption of the general communication apparatus. A common key control apparatus 11 transmits a first status transition request R1 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to a distribution completed status, and transmits a second status transition request R2 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to an in-transit status. The general communication apparatus 12 makes a transition from the update completed status to the distribution completed status upon receipt of a new common key from the common key control apparatus 11, while it makes a transition from the distribution completed status to the in-transit status upon receipt of the first status transition request and it restores the state to the update completed status from the in-transit status upon receipt of the second status transition request.
摘要:
A communication system is constructed in such a manner that a user is allowed to designate a controller 1 and a wireless device 3 simultaneously to start authentication for connection with a wireless base station 2 to specify the device to be connected, and to establish connection authentication without a password for the first time. Thereafter, the controller 1 distributes a password to the wireless base station 2 and to the wireless device 3 to cancel the connection authentication. Next, connection authentication with the distributed password is established. Thus, the communication system makes it possible to substantially automatically establish connection authentication, thereby eliminating a cumbersome operation by the user in implementing the connection authentication process.

One routing device which connects plural networks on which a plurality of other routing devices, including a parent router, are connected. The parent router manages network identification data to identify the plural networks. Master router data is included for each corresponding other routing device. Master router data includes master router identification data identifying whether the corresponding other routing device is a “master router” located on a path to the parent router or a “slave router” which is a routing device other than the master router, and includes network identification data identifying a network to which the corresponding other routing device connects. Upon startup of the one routing device, the master router data is acquired from the other routing devices on the networks to which the one routing device connects. It is determined whether a router function of the one routing device is enabled based on the acquired master router data.

A network system comprising routers and a plurality of sub-networks, each of which connects apparatuses, wherein the plurality of sub-networks are identified by respective Net IDs, and are connected via the routers to form a tree structure. Each of the routers includes: first and second communication interface units that connect multiple sub-networks; a router data storage unit that holds router data including the Net IDs of the respective sub-networks that are connected; and a control unit that performs a cold start, which is a start-up process involving an update of the router data stored in the router data storage unit, wherein the control unit, when performing the cold start, causes each of the routers connected to downstream sub-networks to perform a cold start.

A controller (1) holds appliance data acquired from an appliance (3) regularly and without loss. A display terminal (2) is capable of moving to other rooms through a receptacle and holds the appliance data acquired from the appliance (3). When there is loss in the appliance data for a part of time period because of a move and the like, the display terminal (2) executes acquisition request to the controller (1) to acquire this non-collected data of the appliance. The controller (1) transmits the appliance data to the display terminal (2) in response to the request of the display terminal (2). The display terminal (2) acquires (or complements) the non-collected data from the controller (1) and display the data.
摘要:
The present invention aims to provide a gateway device in order to release information and service information of an appliance to an appliance connected to a network having a different protocol. The gateway device (11) includes a device description creation processing unit (24), a device description template holding unit (25), a service description creation processing unit (26), and a service description template holding unit (27). The service description creation processing unit (26) categorizes services and attributes which each appliance can provide into property types which are control models, and based on a rule defined for each property type, a service information description that is information to be released is automatically created.
