  • Publication number: 20070299577
    Abstract: A portable information terminal stores first function list information indicating the contents of functions installed on a first vehicle. When a user carrying the terminal gets in a second vehicle before driving, the second vehicle acquires the first function list information from the terminal. The second vehicle compares the acquired first function list information with second function list information indicating the contents of functions installed on the second vehicle. The second vehicle acquires a functional difference between itself and the first vehicle and notifies the user of the difference.

  • Patent number: 7027487
    Abstract: A correlator receives an inphase signal and a quadrature signal as incoming signals. In the correlator, a despreading circuit despreads the incoming signals using spreading codes. Further a complex conjugate multiplication circuit 60 multiplies the respective despread signals by the complex conjugate of pilot signals into synchronized signals. The synchronized signals corresponding to a predetermined number of symbols are averaged into average signals. Then the power of the average signals is calculated, and an auxiliary signal is generated by multiplying the power by a factor. On the other hand, the power of the despread signals is calculated, and the power corresponding to the predetermined number of symbols are averaged into an average power signal. The correlation output of the correlator is generated by adding the average power signal and the auxiliary signal. This correlator is immune to the frequency variation of its oscillator and noise.

  • Publication number: 20030084392
    Abstract: A turbo decoder has a control portion, a decoding portion and the like. The control portion determines the repeating number of times of the calculation for the second likelihood Ra to obtain the repeating number of times in association with the condition of the communication environment. The decoding portion decodes the error-correction code by using the repeating number of times determined at the control portion so that the decoded data is obtained efficiently by performing the decode so as to correspond to the condition of the communication environment.

  • Publication number: 20020098815
    Abstract: Base stations have a plurality of antenna devices and a radio communicating zone, respectively. Each base station transmits respective information signals multiplied with a first complex weight from one antenna device and multiplied with a second complex weight from the other antenna device, when the mobile station is within each of the communication zones. The base stations renew the first and the second complex weights based on the direction of the mobile station. One of the base stations determines the initial values of its first and second complex weights based on a direction information of the mobile station obtained when the mobile station was in the zone of the other base station, upon moving from one zone to the other zone.

  • Publication number: 20020080743
    Abstract: A CDMA communication system comprises a base station and a mobile station. In the mobile station, a pilot demodulator demodulates first and second pilot signals by reception path using antenna pilot demodulators. An antenna phase difference calculator determines phase difference Angle(n) for the first and second pilot signals on each reception path. By vector-adding phase difference Angle(1), Angle(2), . . ., Angle(n), average Angle_a is determined as the average phase difference Angle(1), Angle(2), . . . , Angle(n). This average Angle_a is used as the phase difference data for a feedback control in the base station.

  • Patent number: 5117106
    Abstract: A scanning pattern drawing apparatus which scans the surface of a workpiece with a light beam so that a pattern is described on the workpiece with the issued light beam being controlled on the basis of pattern drawing data stored in a pattern memory, wherein the pattern drawing apparatus is able to read many pieces of data in a short period of time even if the frequency of the timing pulses is reduced and which therefore is capable of drawing a precise pattern on a workpiece. A scanning pulse generator produces as scanning pulse in response to a predetermined amount of scanning with the light beam. The scanning pulse is converted to a plurality of resulting timing pulses, and successive parallel outputs of the timing pulses are produced after delaying by a predetermined time. The pattern drawing data is read from the pattern memory in response to the delayed timing pulses.

  • Patent number: 5093561
    Abstract: A drawing surface adjusting mechanism suitable for use with a large scanning pattern drawing apparatus in which a scanning optical system scans drawing rays of light along scanning lines on a workpiece on a drawing board. A plurality of light-emitting units project rays of light in a wavelength region outside a sensitivity range of the workpiece onto a drawing surface of the workpiece in such a way that the rays substantially converge at more than one point along a scanning line of the drawing rays of light, preferably at center and end points along the scanning line. A plurality of condenser lenses are provided for focusing beams of light from the plural light-emitting units after the beams have been reflected by the drawing surface. A plurality of light-detecting elements are disposed at points of condensation by respective ones of the condenser lenses to produce output signals representing differences in condensation points that occur as the lenses depart from or approach the drawing surface.

  • Patent number: 5046796
    Abstract: An apparatus for correcting a scranning beam produced by a polygonal mirror tilting in small surface segments in each mirror surface segment caused by uneven mirror surfaces of the polygonal mirror. Data indicative of the amount of tilting in each of the surface segments is stored in a memory, which is addressed by a data signal indicative of the present scanning position of the polygonal mirror. Output data from the memory is applied to an acousto-optical modulator disposed in the beam path between the light source and the polygonal mirror.

  • Patent number: 5043566
    Abstract: A monitor mechanism for use with a scanning optical apparatus in which the direction of polarization is utilized to separate a source laser light beam into a pattern drawing and a monitor beamlet and to synthesize them again into a single after passing through a scanning lens and beam deflector. The two beamlets can thus be controlled so as to project towards the deflector and scanning lens in the same direction, which is effective in reducing the offset between the pattern drawing and monitor beams that may occur on account of such factors as variations in lens performance.
