Abstract: A heating device includes a first rotator, a heater including a base and a heat generator, and a second rotator contacting the first rotator. The heat generator adjacent to the base defines a heat generation area having one edge close to one edge of the base in a longitudinal direction of the base. A length between the one edge of the base and the one edge of the heat generation area is longer than a length between the other edge of the base and the other edge of the heat generation area. The second rotator has one edge close to the one edge of the heat generation area. A length between the one edge of the second rotator and the one edge of the heat generation area is shorter than a length between the other edge of the second rotator and the other edge of the heat generation area.

Abstract: A software-defined radio equipment includes a hardware/module, implements radio equipment functions by downloading radio communication software that controls the hardware/module from an external source, and switches the radio communication software by using a distributed object. The software-defined radio equipment includes a first means that transmits, when a hardware to be used by the radio communication software is selected from the hardware/module, first predetermined information of the selected hardware, a second means that interrupts an execution of the radio communication software before selection when the selection is reselection and transmits second predetermined information of a selected hardware after the reselection, and a third means that transmits predetermined information of a hardware that is currently being selected. Further, if the selected hardware is the hardware that is currently being selected, an error is detected.

Abstract: This software wireless device comprises framework software that installs wireless communication software; and interface service software that is provided so as to be directly managed by an OS, and that manages a user interface service and the framework software. The framework software has user interface software, domain management software, hardware management software, and hardware control software. The interface service software issues a running status monitoring request to the user interface software and the domain management software, and determines that there is an abnormality if there is no response from the user interface software or the domain management software.

The communication device includes: first means for judging whether communication control information can be compressed or not on the basis of a neighboring node search message among the plural communication devices and a response thereto, or the exchange of routing control information according to an ad hoc routing protocol; and second means for compressing the information volume of the communication control information by judging the contents of the communication control information and deleting or replacing redundant information or constantly fixed information if the communication control information can be compressed.

Abstract: Domain management functionality is implemented internally to a software-defined radio device. A software-defined radio device that includes plural hardware modules 220 to 222 and implements radio device functions by downloading radio communication software programs 203 for controlling the plural hardware modules from outside. The software-defined radio device includes domain management software 202 among environment software programs 215 that are activated when the device is activated. The domain management software generates an interface necessary to use each of the radio communication software programs according to a domain for each of the radio communication software programs and performs activation, setup, and connection with other programs for each of the radio communication software programs.

Abstract: In a communication device and a communication method, multiple pieces of QoS control information are stored in a routing information base, each piece of QoS control information, with a terminal wired to the communication device itself as a transmission source, defining a bandwidth control value and a priority degree that correspond to communication data specified by a combination of the transmission source and a destination. When communication data is inputted, a control unit selects QoS control information that matches a combination of the transmission source and the destination of the inputted communication data from among the stored multiple pieces of QoS control information and indicates a bandwidth to a bandwidth control unit on the basis of the selected QoS control information, indicates a priority degree to a DSCP marking unit, and performs wireless transmission.

Abstract: A communication device that is used for ad-hoc network communication or wireless mesh network communication includes a setting interface unit configured to set an IP address of a communication device corresponding to low-delay communication, and an ad-hoc routing control unit. When a request for low-delay communication is provided from the setting interface unit, the ad-hoc routing control unit determines a route matching the IP address of the communication device and determines whether the low-delay communication is possible. The ad-hoc routing control unit sets a control message transmission interval to the maximum interval when the low-delay communication is possible, and sets the control message transmission interval to the minimum interval when the low-delay communication is not possible.
