Abstract: The object is to enable suppression of an excessive number of changes in assignment of a server in charge of communication in response to movement of a terminal. A position-information acquisition unit in a computer acquires information on the position of a mobile terminal as a candidate for a destination of information provision. Then, a zone determination unit determines whether or not the mobile terminal is in a coverage zone or a margin zone on the basis of the information on the position. An information provision unit starts the information provision to the mobile terminal when the mobile terminal enters the coverage zone, and ends the information provision to the mobile terminal when the mobile terminal goes out of the margin zone.

Abstract: A film antenna whose antenna characteristics are unaffected by chassis is provided. A recessed groove portion 26 is formed in a ground portion 13 which is attached to a chassis 18. A first radiating element portion 14 is formed from a wall 26a on one side of the groove portion 26 to a wall 26b on the other side. A capacitive coupling piece portion 27 which is capacitively coupled via a specified gap g to the first radiating element portion 14 is formed on the wall 26b on the other side to thereby allow antenna characteristics to be unaffected by the chassis 18.

Abstract: This invention is to enable transfer of a right to speak in an audio teleconference in view of usability. In this invention, a PoC server is introduced to achieve new functions, such as transfer of the right to speak, reservation to acquire the right to speak, and deprivation of the right to speak. The PoC server has a teleconference presence manager, a teleconference manager, and a teleconference audio communication manager. The right to speak is managed in a presence data storage of the teleconference presence manager. The teleconference presence manager directly manages the presence data storage, but the teleconference manager manages transfer of the right to speak. In addition, the teleconference manager manages reservation of the right to speak by a storage for a reservation list of the right to speak. The teleconference audio communication manager carries out routing of audio data. At that time, only audio data received from a user holding the right to speak is transferred.

Abstract: A double-laterally-wound two-core parallel extrafine coaxial cable includes two cores, having internal conductors whose outer peripheries are covered with insulators and disposed in parallel with each other. A first laterally-wound shield is applied to the outer periphery of the two cores. A second laterally-wound shield is applied to the outer periphery of the first laterally-wound shield in a direction opposite to that of the first laterally-wound shield. A composite tape, which includes a plastic tape having a vapor-deposited metal layer formed on one surface thereof, is wound around the outer periphery of the second laterally-wound shield such that the vapor-deposited metal layer faces the second laterally-wound shield. A jacket covers the outer periphery of the composite tape. Each of the cores has a core outer diameter, and the laterally-wound shields are formed of wire having a wire diameter.

Abstract: A double-laterally-wound two-core parallel extrafine coaxial cable is composed of two cores having internal conductors (2a, 2b) whose outer peripheries are covered with insulators (3a, 3b) and disposed in parallel with each other, a first laterally-wound shield (5) applied to the outer periphery of the two cores (4a, 4b), a second laterally-wound shield (6) applied to the outer periphery of the first laterally-wound shield in a direction opposite to that of the first laterally-wound shield, a composite tape (9), which is composed of a plastic tape (7) having a vapor-deposited metal layer formed on one surface thereof, wound around the outer periphery of the second laterally-wound shield such that the vapor-deposited metal layer faces the second laterally-wound shield, and a jacket (10) covering the outer periphery of the composite tape.

Abstract: It is an object of the present invention to provide a two-core parallel extra-fine coaxial cable having a high shield effect and sufficient flexibility for being wired in a narrow space. To achieve the object, the invention provides a two-core parallel extra-fine coaxial cable comprising, two parallel cores 4a and 4b having inner conductors 2a and 2b whose outer peripheries are coated with insulations 3a and 3b, a transversely wound shield 5 provided around outer peripheries of the two cores 4a and 4b, a composite tape 8 which comprises a plastic tape 6 formed on its one surface with a metal deposition layer 7 and which is wound around an outer periphery of the transversely wound shield 5 such that the metal deposition layer 7 comes on the side of the transversely wound shield 5, and a jacket 9 for coating an outer periphery of the composite tape 8.
