Abstract: A wireless communication device mountable in a vehicle acquires first position information on the vehicle and receives a packet signal from another wireless communication device, the packet signal including second position information on another vehicle in which the other wireless communication device is mounted. The wireless communication device has a storage that stores log information and a controller. The controller predicts whether the vehicle crosses the other vehicle at a point of crossing based on the first position information and the second position information, estimates a structure of crossing corresponding to the point of crossing based on the history information, and determines, when it is predicted that the vehicle crosses the other vehicle at the point of crossing, whether or not to notify a presence of the other vehicle to a driver of the vehicle, in accordance with the structure of crossing corresponding to the point of crossing.

Abstract: Techniques for suggesting a tag for content may include the following: receiving, from a member of a social network, an entry in a display field along with an indication that the entry is for a post; after receiving the entry and the indication, identifying content by performing a search using at least some of the entry and information about the member of the social network; obtaining tags corresponding to the identified content; ranking the tags; outputting the ranked tags as suggestions to include with the display field; and augmenting the entry by adding a selected tag to the display field.

Abstract: A receiving apparatus receives from another terminal apparatus a packet signal, which contains the positional information and the mobile information. A terminal identifying unit identifies a second terminal apparatus installed in a second vehicle in front of a first terminal apparatus installed in a first vehicle in front of the receiving apparatus, based on the positional information and the mobile information contained in the packet signal received. A warning unit processes the packet signals sent from the second terminal apparatus and outputs their processing results.

Abstract: A digital matched filter includes a received signal holding unit for holding received signal samples, a spreading code generating unit for generating known spreading codes, and a correlation value calculating unit for calculating a correlation value between the received signal samples and the spreading codes. The received signal holding unit is formed of a plurality of registers arranged in parallel and gate circuits are provided at respective preceding stages for masking signal input unless signal writing is to be performed. The correlation value calculating unit is formed of a plurality of slow-operation calculating circuits arranged in parallel. Each calculating circuit is divided into product-sum calculating units at the anterior and posterior stages respectively. The product-sum calculating unit at the posterior stage is stopped when it is not the time of detecting a peak value in order to reduce power consumption.

Abstract: A matched filter is provided with a plurality of taps and calculates correlations between a baseband signal and a diagnosis signal series. The matched filter derives the diagnosis signal series, based on the first through fourth preamble patterns that are candidates for a match with a preamble pattern included in the baseband signal. A hopping pattern detection unit averages the correlations output from the matched filter for each symbol. The hopping pattern detection unit generates and analyzes delay profiles so as to detect a frequency hopping pattern. A symbol timing detection unit averages the correlations output from the matched filter over the symbols. The symbol timing detection unit generates and analyzes delay profiles so as to detect symbol timing in steps.

Abstract: A digital matched filter includes a spread code generating unit, a spread code holding unit, a reception signal holding unit, a tap calculating unit, an adding unit and a correction value generating unit. To the tap calculating unit, a tap output is provided from the reception signal holding unit, and a tap coefficient is provided from the spread code holding unit. A code control unit is provided in the tap calculating unit for each corresponding tap output and tap coefficient. The code control unit provides an output corresponding to the tap output with or without inversion in accordance with the tap coefficient. A correction value generated by the correction value generating unit is added to the sum of the outputs from the code control units. Thus, an error in a correlation value output is corrected.

Abstract: The user of a cellular phone accesses a server using his/her own cellular phone via a base station, a telephone communication network and a base station control unit, to make a distribution request for music content data. The server distributes the requested music content data and a ringing tone to the cellular phone after the authentication of the accessing cellular phone is verified. Here, the user of the cellular phone only pays the price for music content data. Therefore, the user of the cellular phone can easily register or renew ringing tones.

The parallel spaced plate springs are caused to bend to displace the objective lens holder and the objective lens in the focusing direction.

Abstract: An optical unit actuator for an optical information recording/reproducing apparatus includes an electromagnetic drive mechanism composed of a coil and a magnet cooperative to drive an objective lens mounted on an optical unit. One of the coil and the magnet is secured to the optical unit. The other of the coil and the magnet is held on a fixed unit with an elastic support member disposed therebetween, the fixed unit being immovable as against the movable optical unit. The elastic support member substantially dampens or takes up vibration caused by a reaction force creased as a result of acceleration of the objective lens when the objective lens is driven to follow a dynamic radial runout and an axial deflection of an optical disk. With the elastic support member thus provided, an optical component, a photo-electric transducer or the optical disk which is disposed on the side of the fixed unit is isolated from vibration.

Abstract: Spherical products of a heat-softened material are produced by supplying a molten heat-softened material into a C-shaped channel-like spinner with an open upper surface and a large number of orifices formed in its circumferential wall, at a rate of 0.020 kg/hr or lower per a single orifice of the spinner; rotating the spinner at a high speed to form cone-like fine streams of the molten material from the orifices by means of a centrifugal force; and flowing streams of a hot gas so as to traverse the fine streams of molten material to thereby heat the same resulting in reducing the viscosity of the molten material and to break the fine streams by the hot gas streams.
