Title: Enhanced conversion of wideband signal to narrowband signal
Inventor: EL-MALEH KHALED H
IPC: G10L25/93
Filed: 2009-02-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technology for converting wideband speech signals to narrowband speech signals without losing acoustic quality.  <P>SOLUTION: Wideband speech signals must be converted to narrowband speech signals if a transmission medium or a destination terminal is constructed with narrowband constraints. A typical wideband-to-narrowband conversion method is elimination of frequencies above 3400 Hz using a low pass filter and a down sampler. However, this method produces a muffled speech sound since the resulting narrowband signal includes a flat frequency response. Methods and apparatus are presented herein to enhance the acoustic quality of a wideband-to-narrowband converted signal. A bandwidth switching filter is used to emphasize a mid-range frequency portion of the wideband signal so that the resulting narrowband signal includes a non-flat frequency spectrum.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Image forming apparatus
Inventor: TAKAHASHI OSAMU
IPC: G03G15/01
Filed: 2009-02-27
Abstract: <P>PROBLEM TO BE SOLVED: To make it possible for an image forming apparatus, which forms patch marks on a carrier element and detects specular reflected light and diffuse reflected light from the patch marks, to eliminate influence or the like of stray light from detected values of the specular reflected light and the diffuse reflected light and to thereby accurately detect a density.  <P>SOLUTION: As the quantity of toner adhesion increases, the specular reflected light from the patch marks decreases in an inversely proportional manner, but the diffuse reflected light linearly increases. For these reasons, since the output Vdf of a diffuse reflected light-receiving element linearly increases with an increase in the quantity of toner adhesion. Conversely, when the quantity of toner adhesion increases, the output Vsp of a specular reflected light-receiving element increases after it temporarily decreases. In a high density area where the quantity of toner adhesion is 0.6 g/cm<SP>2</SP>or more, the outputs become Vsp=Vdf. When the outputs are offset as represented by Vsp' and Vdf' due to the influence of stray light or the like, correction parameters for achieving Vsp'=Vdf'×Gdf+offset at a plurality of points in the high density area are obtained, wherein a Gdf serves as a first correction value and an offset serves as a second correction value.  <P>COPYRIGHT: (C)2010,JPO&INPIT
