Abstract: A plasma display device which can provide stable discharging operations irrespective of variations in temperature. A load capacitor of a plasma display panel is charged or discharged via a switching element and a resistor element with one end to which a predetermined potential is supplied thereby creating a gradually varying waveform of a drive pulse, in which the switching element is controlled by an operational amplifier. That is, the operational amplifier controls the switching element based on a control voltage according to the difference between the potential at the other end of the resistor element and the potential of a gradually varying waveform generation signal for promoting the gradually varying waveform to be generated.

Abstract: A description generator in a user terminal has a group of destination description dictionaries provided for description categories each constructed by a destination and an expanded destination obtained by expanding the concept of the destination. The description generator describes type information by using vocabularies in the destination description dictionaries. A description interpreter in a central system for interpreting the destination description generated by the user terminal specifies a description category (either a destination or an expanded destination) by determining a dictionary for destination description to which the vocabulary used for describing the type information belongs.

Abstract: A vector retrieval/generation/correction unit of a user terminal generates, corrects, and optimizes an inquiry vector on the basis of a vector profile, an inquiry history, a user model, and a user profile. On the other hand, a vector retrieval/generation/correction unit in an information center generates/corrects/optimizes a feature vector on the basis of a vector table, a search history, and a contents description database. In the information center, when an inquiry profile including an inquiry vector is transmitted from the user terminal, an adaptive searching process is executed. According to evaluation made by a contents evaluating unit, proper contents are retrieved from a contents database.

Abstract: A color information creating part calculates the average color of captured image data in units of macro blocks, and determines to which color index the average color of each macro block corresponds. Color arrangement information formed by associating color information with the macro blocks is stored in a color index memory. A histogram creating part creates color histograms representative of the distribution of macro blocks added with color information corresponding to aimed color indexes. Based on the color arrangement information and the color histograms, a color application execution part recognizes objects, surroundings, or the situation of a driver's own vehicle without performing area splitting (shape acquisition) of an image.

Abstract: An information service system having user terminals and a center in which information according to a request for retrieval is provided to users at a low cost while simplifying setting of conditions for retrieval at the user terminals is simplified and maintaining real-time properties. A profile database at a center is updated using profile information transmitted by user terminals to construct an information database. Further, profile information used for retrieval is generated such that it includes information on the environment and situation around a user and information of requests and status of the user to allow proper retrieval in addition to verbal information from the user. The center searches the information database based on such profile information to provide information to the user terminal.

Abstract: A user information inferring system defines user information according to five categories, that is, user environment, circumstance, condition, request, and action, and further defines a sixth category, that is, situation data encompassing these other five categories. User information in each of the defined categories, that is, environment, circumstance, condition, request, action, and situation, is then described using item values, and operating units infer the item values. The inference operation uses temporal-spatial characteristics indicative of the effect of temporal-spatial elements on the item values, information about inferred situations, a rule database containing rules describing the relationships between items, and an optimization process for the defined categories using vector expressions.

Abstract: When a start key is operated, an inferring process of estimating a demand of a user is executed on the basis of preset situation data, a user profile, and situation data manually input via a situation setting key. Based on the inference result, a genre list and a contents list are reconstructed so that genres and contents items are arranged in order of the degree of a demand of the user. The top three genres extracted from the reconstructed genre list are associated with three selection keys, and the names of the associated genres or labels of the genres are displayed in genre name display parts. It enables the user to easily and instantaneously select one of contents items to be processed.

Abstract: A dew condensation detecting apparatus is independent of a wavelength of a detected light beam, and has a heat capacity of the detecting apparatus body so as to miniaturize the apparatus. A light beam is introduced from a light emitting element into the transparent plate and travels through the transparent plate with repetitions of total reflection. It is then detected by a light receiving element to detect a degree of dew condensation on a surface of the transparent plate in accordance with a variation in detected light quantity. The transparent plate is formed of two sheet glasses bonded to each other by an intermediate film, a part of which is a reflection film. A micro-mirror array for turn-back reflection, composed of oblique reflection surfaces inclined to the surfaces of the spaced sheet glasses, is provided near one end of the reflection film.

Abstract: First, in a microcomputer of a communication terminal, data communication request is carried out. Next, a profile corresponding to contents of requested data is received from a communication control device. The microcomputer then selects one of communication systems based on the profile. The result of the selection is notified to the communication control device. Then, a transmission request signal is transmitted from the microcomputer. Thereafter, the data is received from the communication control device through the selected communication system. Thus, the download through the selected communication system is completed.

Abstract: A speech inputted via a microphone is recognized by a speech recognition unit. Based on a recognition result, a dialogue control unit makes a music search unit search a music index database. When a search result includes plural musical compositions, a certain composition is designated from the plural musical compositions, based on an optional search method, to be immediately reproduced. The certain composition can be randomly designated. It can be also designated based on a frequency each composition was reproduced, a date and an hour when each composition is stored, a sale date, or a degree of matching to the inputted speech. This structure enables any musical composition to be immediately reproduced even without user's final input to designate only one of the musical compositions. This results in shortening a non-responding period where no music is being reproduced to enhance a comfort level of the user.
