20100003083 | DIVING EQUIPMENT - Diving equipment easily operable by disabled persons, aged persons, etc. and wearable by oneself. The diving equipment such as buoyancy controlling device (BCD) has the function to hold a tank on the shoulder of a wearer and the function as a life jacket providing buoyancy to the wearer. In the diving equipment (BCD) of which the overall is formed in a vest-like shape, a tank holding part ( | 01-07-2010 |
20100246803 | Bandwidth extension apparatus for automatically adjusting the bandwidth of inputted signal and a method therefor - A bandwidth extension apparatus can generate from an inputted speech signal a bandwidth-extended signal whose bandwidth is automatically adjusted according to the surrounding hearing situation by means of a parameter. The apparatus has a surrounding characteristic predictor for predicting the characteristic amount of the surrounding sound of the phone terminal on which the apparatus is installed; an adjustment amount predictor for comparing the characteristic amount with the parameter to predict the adjustment amount for the parameter; a speech characteristic predictor for predicting the characteristic amount of the inputted speech signal; and an adjustment amount determiner for determining an adjustment amount for updating the parameter based on the characteristic amount of the surrounding sound and the inputted speech signal. | 09-30-2010 |
20110075832 | Voice band extender separately extending frequency bands of an extracted-noise signal and a noise-suppressed signal - A voice band extender includes a component separator for receiving a band-limited speech signal over a telecommunications line to separate the speech signal into a noise-suppressed signal and an extracted-noise signal, a noise-suppressed signal component extender for adding a signal having its frequency band higher than that of the noise-suppressed signal to thereby produce an extended noise-suppressed signal, an extracted-noise signal component extender for producing an extended extracted-noise signal, a signal intensity adjuster for adjusting signal intensity of either or both of the extended noise-suppressed signal and the extended extracted-noise signal, and a synthesizer for combining the extended noise-suppressed signal and the extended extracted-noise signal obtained by the intensity adjustment. The respective frequency bands of the extracted-noise signal and the noise-suppressed signal are thus extended. | 03-31-2011 |

20090019343 | Loss Compensation device, loss compensation method and loss compensation program - It is possible to save storage resources. A loss compensation device for compensating a loss in periodical signals when the loss occurs in an arbitrary section of the periodical signals which are divided into predetermined sections and received in time series, includes: a periodical signal storage which stores one or more sections of newly received periodical signals for a predetermined period of time; a loss detector which detects a loss of each section of the periodical signals; and an element periodical signal generator which generates a plurality of element periodical signals for interpolation having different waveforms, in accordance with the periodical signals stored in the periodical signal storage, at time of detection of the loss if the loss is detected by the loss detector. The plurality of element periodical signals generated by the element periodical signal generator are synthesized, and a result of the synthesizing is arranged at the section where the loss in the periodical signals has occurred. | 01-15-2009 |
20090176449 | Out-of-Band Signal Generator and Frequency Band Expander - An out-of-band signal generator for generating, from a band-limited signal with a limited frequency band, an out-of-band signal including a frequency component outside the limited frequency band, having a frequency structure estimating means for estimating the frequency structure of the band-limited signal, an out-of-band source signal generating means for generating an out-of-band source signal including an out-of-band frequency component from the band-limited signal, a frequency structure adjusting means for adjusting the frequency structure of the out-of-band source signal according to the estimated frequency structure of the band-limited signal, and a component extracting means for extracting a prescribed band in the out-of-band source signal with the adjusted frequency structure. | 07-09-2009 |
