A new mobile control system, a mobile control method, a mobile control device and a mobile control program, which are capable of achieving efficient control by integrating a plurality of mobile control services when simultaneously applying a plurality of mobile control services to mobile terminals or exchange networks, are provided. The mobile control method manages and controls an exchange network N communicably connecting a plurality of mobile terminals 10, and when a plurality of mobile control services regarding the same mobile terminal 10 is performed on the exchange network N either simultaneously or within a predetermined time, integrates the various mobile control services, thereby achieving economic and efficient control.

Rerouting of packet exchanges by a mobile terminal is controlled so as to be optimized on a real time basis to prevent network resources from being wasted by redundant routing. In an initial state a route of data from a mobile communication terminal M to a CN 8, which is a communication partner, is a route R5. Then, an access router (AR) 72 acquires the number of hops of data received from the CN 8 by the mobile communication terminal M. As the mobile communication terminal M now performs a handover to under the command of the AR 73, the route will change to a route R9. Then the AR 73 detects that the route becomes redundant by the fact that the number of hops acquired after the shift is greater than the pre-shift number of hops received from the AR 72, and invokes control to reroute to a route R7, which provides the optimal routing.

Disclosed is a technique for providing an image display device enabling a user to understand the entire correspondence relationship between a three-dimensional photographed image and a two-dimensional map image. According to the technique, when a photographed image and a map image in the imaging position are separately displayed on the screen of an image display unit 33, a map drawing unit 24 reads the position information (x, y) of the camera and the azimuth angle φ of the camera, reads a view angle θ of the camera, and reads map data around the imaging range of the camera using the position information (x, y) of the camera to process and draw the map image so that the view angle θ and the azimuth angle φ match the view angle θ and the azimuth angle φ of the photographed image taken by the camera.

Disclosed is a display system capable of achieving a prompt drive-forced function even in an environment where, as in a remote UI, a delay occurs until a change by an information providing device is reflected in an information display device. This display system is provided with an information providing device (101) and an information display device (111), said information providing device (101) comprising a communication section “a” (104) and an accumulation section (102) which accumulates scripts (103) that include displayed parts constituting displayed images and the arrangement thereof, descriptions of animation movements etc. of the displayed parts, and drive-forced flags for all of the displayed parts, and said information display device (111) comprising a communication section “b” (112), a script processing section (113), a display section (114), and a sensor determination section (115).
摘要:
A plurality of vertical bends are provided in a terminal projecting from a switch contact outwardly of a case. With this structure, when the terminal is soldered to a land on a wiring board, a plurality of solder layers are formed between the plurality of bends and the land. The plurality of solder layers can enhance the terminal strength, thereby preventing the switch from coming or floating off from the wiring board. Thus, a switch capable of ensuring reliable operation can be provided.

An input apparatus includes a case, an operation body stored rotatably in the case, a magnetic body fixed to the operation body, a magnet provided around the operation body, a magnetic detection element for detecting a magnetic flux from the magnetic body, and a frame for retaining the case. The magnetic detection element faces the operation body with a predetermined space therebetween. The frame includes depression sections for causing the magnetic detection element to elastically contact the lower surface of the case. This input apparatus can accurately detect a rotation angle.
