A communication device is used by a mobile station to perform wireless communication with another mobile station. The communication device includes a processor configured to set a transmission resource according to a present position of the mobile station, the transmission resource being set based on transmission resource association information including different transmission resources assigned to plural assignment areas provided at different positions along a road through which the mobile station passes; and a transmitter configured to transmit data with the use of the transmission resource that has been set.

In a mobile communicating system, a mobile terminal has a position information detecting unit detecting position information, a position information transmitting unit transmitting position information to an information center, an up-load data transmitting unit transmitting up-load data to the information center and an information/service utilizing unit utilizing information/service from the information center. The information center has an accumulating unit accumulating information/services, a retrieving unit receiving the position information from the mobile terminal to retrieve the information/services in the accumulating unit, an accumulation controlling unit accumulating the up-load data in the accumulating unit, and an information/service transmitting unit taking out the information/service retrieved by the retrieving unit from the accumulating unit and transmitting it to the mobile terminal, thereby providing not only map information showing the current position of the mobile terminal but also information of facilities on the map to the mobile terminal.

When an antenna receives a signal, the signal is inputted to delayers through a frequency converter, A/D converters, quadrature demodulators, filters and simultaneously is inputted to a MUX. The receiving signal inputted to the MUX is transmitted to an interference canceler panel, and the interference canceler panel generates both an interference replica signal and a symbol replica signal. The interference canceler panel demodulates the receiving signal for a channel corresponding to the symbol replica signal using both the interference and symbol replica signals. The interference replica signal generated by the interference canceler panel is transmitted to a transmitting/receiving panel and is inputted to interference elimination units. The interference elimination units eliminates interference components by subtracting the interference replica signal from the receiving signal delayed by the delayers and transmits the signal to a baseband signal processing panel.

When a source subscriber activates a voice communications unit of a computer, an agent process unit in a computer center receives a data stream transmitted from a voice communications unit. The agent process unit activates a voice communications unit capable of communicating with the voice communications unit, and transfers the data stream from the voice communications unit to the voice communications unit. A network control unit transmits a telephone number stored in a telephone number storage unit. Thus, communications can be established between the computer and a telephone terminal.

Apparatus and method of connecting computer network to telephone

An agent is permanently resident in a server as software for the purpose of cryptographic processing. In addition, another agent that is described in mobile code and contains a program for the purpose of cryptographic processing is also stored in the server. When data that are to be sent and received between the server and a client are encrypted, the agent that is described in mobile code is sent from the server to the client. When the client receives data that were encrypted in the server, it reproduces those data by decryption using the received agent.

A single antenna is used so that time-division transmission and reception is carried out in a radar apparatus for obtaining a distance and a relative speed with respect to a target object based on a beat signal obtained by transmitting a frequency modulated signal and mixing a received signal reflected by said target object with the frequency modulated signal that is transmitted.

Radar apparatus with a simplified construction

A high frequency signal, which is produced in a oscillator, is modulated by a frequency from a modulating signal generated by a modulation signal generator and radiated from a sending antenna. A reflected signal from a target object is received by a receiving antenna, and frequency-converted by a local oscillating signal from a directional coupler in the frequency convertor. Then, distance and speed information is detected by a signal processing unit. A modulator, which is connected to the oscillator, modulates the oscillator output in order to detect a failure. A detection unit, in which a filter unit, a rectification circuit, and a voltage comparison circuit are included, detects modulated elements originated in the above described modulator. The signal processing unit makes a failure determination based on the modulated elements which have already been detected.

A coaxial line assembly in a package which houses a high frequency element. The assembly includes a metal wall having a hole extending through the metal wall. The metal wall has a step at substantially an intermediate portion of the hole to define a smaller diameter, inner hole portion opened to the inside of the package and a larger diameter, outer hole portion opened to the outside of the package. A lead for transmitting a high frequency signal passes through the hole and is hermetically sealed in the outer hole portion by glass filled in the outer hole portion. A sealing plate closes an opening of the inner hole portion at the step, the lead extending through the sealing plate. The sealing plate is made of a dielectric material having a dielectric constant near to that of the glass and a melting point higher than that of the glass.
