Abstract: A radio communication apparatus is provided in Protocol Data Unit (PDU) transmission, in which the tail end (boundary) of a packet is detected based on the calculation result of an error detection calculation (Frame Check Sequence (FCS) calculation), without use of Length Indicator (LI) information. Preferably, to avoid incorrect detection, tail end presence/non-presence flag information is set in a header, and the above detection is decided to be valid when the flag information in the header part of PDU, storing the detected tail end, indicates the presence of the tail end.

Abstract: Disclosed is a travel-time prediction apparatus that is capable of making a mid-term prediction of travel time accurately by combining present conditions and statistical information. The apparatus includes a travel-time transition pattern database storing travel-time transition patterns obtained by statistically processing past time-series data of each road link according to type of data. Upon accepting a travel-time transition pattern corresponding to a specified link and day type from the database, the apparatus calculates conversion parameters of a travel-time transition pattern for which an error between the travel-time transition pattern and a sequentially input travel-time time-series data will be reduced, and then makes a prediction using a prediction function obtained by converting the travel-time transition pattern by the calculated conversion parameters. The calculated predicted value and the conversion parameters are distributed as traffic information.

Abstract: A sound generating device of an electronic keyboard instrument, which eliminates overlap between frequency bands to avoid sound wave interference to stabilize acoustic characteristic. Woofers are disposed at a bottom part of a speaker box and directed downward, and squawkers are disposed at an upper part of the speaker box and directed upward. In a DSP, waveform data selected from waveform data groups are input into a MIX, and a waveform signal containing high and low frequency band components is produced from a signal output from the MIX. In a distributor, the waveform signal is converted into an analog signal which is then separated into a musical tone signal only containing the high frequency band component and a musical tone signal only containing the low frequency band component, and these musical tone signals between which there is no frequency band overlap are supplied to the tweeter and the woofer.

Abstract: An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different inks, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these inks. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of an ink that tends to show density unevenness is set higher than that of an ink that tends to show other image impairments more conspicuously than the density unevenness. This results in a good image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire color gamut.

Abstract: In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

Abstract: When a gradation mask is used to distribute image data to be recorded by overlapping portions in an overlapping head, color unevenness is generated in an image recorded by the overlapping portions due to a displacement in impact positions caused by an assembly error. As a result, accurate colorimetric measurement of patches recorded by the overlapping portion cannot be performed. To solve such a problem, a distribution ratio by which the image data is distributed to the overlapping portions is set to be approximately constant when recording a test pattern for performing color correction, as compared to when normally recording the image.
