A communications system includes a first communications part configured to perform communications with a terminal apparatus, a second communications part configured to perform communications via a network, a connection controller configured to start establishing a connection or release a connection between the first communications part and the second communications part, a display part configured to display authentication information transmitted from the terminal apparatus, an input part configured to receive an input from a user, and a connection manager configured to manage a time to allow the user to have a connection to the network in accordance with an instruction input by the user when the authentication information displayed by the display part matches authentication information reported in advance to the user who has been allowed to have the connection to the network.

System and method for managing and authenticating communications connections

In the present invention, a connection controller controls opening/closing of connection between a first communication unit that communicates with a terminal device and a second communication unit that communicates via a network. A connection setting unit instructs opening/closing of the connection to the connection controller in accordance with a user input received by an input unit in accordance with first identification information output from the terminal device displayed on a display unit.

Communication system and communication method

In a data transmission apparatus and method of the present invention, a specific operator ID for an operator who uses a data processing device to process image data to be copied or transmitted, is selected. Specific owner IDs for owners who are authorized to access the image data, are selected. User identification data, inclusive of all operator IDs and owner IDs correlated to the data processing device, are stored in a storage device each time image data is captured by the data processing device. Allocation of the stored user identification data to each of the image data is managed by reading items of the user identification data from the storage device in response to the selections of the specific operator ID and the specific owner IDs and displaying the user identification data items.

A document classification system and method reflects operator's intention in a result of classification of document so that an accurate result of classification can be achieved. The document to be classifies has contents contains a plurality of items. At least one of the items contained in the document is designated. The document data is converted into converted data so that the converted data contains only data corresponding to the designated item. Classification of the document is done by using the converted data.

The speaker recognition methods and systems of the current invention involves at least two processing units for performing the speaker recognition based upon his or her voice input. To perform the speaker recognition efficiently as well as securely, the voice input is initially processed at the input site so that intermediate voice characteristic information is extracted. The intermediate voice characteristic information is transmitted to a second location for the final determination for identifying or verifying a speaker.

Both of voltage range and supplied power range of a heater can be enlarged, one-sided power source for a driving circuit can be realized easily, power source voltage can be lowered, and flowing velocity can be measured with high accuracy. First reference resistor is connected in series to fluid temperature measuring body, and second reference resistor is connected in series to heater temperature sensor. Temperature setting resistor for determining set temperature difference between the heater temperature sensor and the fluid temperature sensor is connected in series to the fluid temperature sensor. Bridge circuit is constructed in such way. The voltage of heater temperature sensor is inputted to non-inverted input terminal of differential amplifier, while the voltage of fluid temperature measuring body and temperature setting resistor is inputted to inverted input terminal of the same. The output terminal of the differential amplifier is connected to a buffer circuit.

A heater-heat sensor type thermal flow sensor including a substrate installed in a fluid path, a channel formed on a part of the substrate; a bridge suspended over the channel; a heater constructed with an electric resistor formed on the bridge; a temperature sensor for measuring the temperature of the heater which is constructed with another electric resistor situated on the bridge and measuring the temperature of the heater; and a fluid temperature sensor constructed with still another electric resistor formed on a position of the substrate not thermally affected by the heater. There is a bridge circuit including the temperature sensor for measuring the temperature of the heater, the fluid temperature sensor, and first and second resistors both installed outside of the fluid path. A control circuit is provided to control the voltage applied to the heater in accordance with the output of the bridge circuit. The heater and the heat sensor are superposedly formed on the bridge through an interlayer insulating film in order to substantially eliminate the difference between the temperatures of the heater and heat sensor. A temperature compensating circuit is connected to the output stage of the control circuit.

A timing reproduction device includes a timing error detector for detecting an error in timing of a signal transferred between a transmission side and a reception side on the basis of a received signal and for generating a timing error signal. An integrator integrates the timing error signal to thereby hold data necessary to maintain a timing synchronization. A sensing unit senses abrupt timing change in the received signal. A timing synchronizing unit executes a timing synchronizing operation for maintaining the timing synchronization by referring the data held in the integrator. A cutoff unit executes a cutoff operation which prevents the timing error signal from being applied to the integrator on the basis of the abrupt timing change sensed by the sensing unit.
