摘要： A speech decoding device of the invention smoothes, in decoding speech signal in a voice-less period, RMS and filter coefficients which is discontinuously transmitted, and provides them to a synthesis filter. Thereby, it is capable of preventing discontinuous changing of the filter coefficient caused by the intermittent transmission of the filter coefficient. As a result, a quality of decoding can be improved. Also, to remove an effect, caused by the smoothing process, from the filter coefficients or the RMS which are transmitted in the past frames, a smoothing factor is adjusted not to perform smoothing while a certain time period (or a certain number of frames) from when a transition is made from a voice period from a voice-less period, or when a decoded feature parameter satisfies a predetermined condition.

摘要： An error detection encoder comprises separation circuitry for separating an input signal into a first sequence of error protected bits and a second sequence of error unprotected bits. Calculation circuitry produces an error check sequence from the first sequence and concatenates the error check sequence to the first sequence to produce a third sequence. The second sequence may be further separated into a first sub-sequence of higher significant bits and a second sub-sequence of lower significant bits. A multiplexer is provided for segmenting the third sequence into a plurality of first blocks and segmenting the first sub-sequence into a plurality of second blocks corresponding to the first blocks and multiplexing each of the first blocks with a corresponding one of the second blocks to produce a fourth sequence in which the first and the second blocks are arranged in an alternating order. The second sub-sequence is concatenated to the fourth sequence to produce an output sequence for transmission.

摘要： A transmission channel error detection code addition apparatus includes a division section, calculation section, and transmission section. The division section divides a code bitstream obtained from input information having a coding unit time length which is an N integer multiple (N>=2) of an error detection unit time length into N bitstreams. The calculation section calculates an error detection code of each divided bitstream output from the division section. The transmission section sequentially transmits each divided bitstream output from the division section and the error detection code output from the calculation section in correspondence with each divided bitstream.

摘要： To achieve an intermediate lock state in a short period when an engine is stopped and improve the accuracy of confirmation of the intermediate lock state, an engine valve timing control apparatus includes a variable valve timing mechanism configured to vary engine valve timing, and an intermediate lock mechanism configured to restrict relative rotation positions of a first and a second rotor of the valve timing mechanism at an intermediate lock position for starting the engine. Upon detection of an engine stop request, the valve timing mechanism and the intermediate lock mechanism are driven and controlled for establishing an intermediate lock state. When a predetermined period from detection of the engine stop request has expired without detecting the intermediate lock state within the predetermined period, an engine stopping process is executed. Even after the engine stopping process has been executed, monitoring of the intermediate lock state is continued.

摘要： A sound data decoding apparatus based on a waveform coding method includes a loss detector, sound data decoder, sound data analyzer, parameter modifying section and sound synthesizing section. The loss detector detects whether a loss exists in a sound data. The sound data decoder decodes the sound data to generate a first decoded sound signal. The sound data analyzer extracts a first parameter from the first decoded sound signal. The parameter modifying section modifies the first parameter based on a result of the detection of loss. The sound synthesizing section generates a first synthesized sound signal by using the modified first parameter. Thus, a deterioration of sound quality is prevented in the error compensation of sound data.

摘要： Disclosed is a conventional organic light emitting diode (OLED) having one reflective electrode in combination with at least one transparent OLED in stacked configuration functioning as backlighting in a transflective display apparatus such as a liquid crystal display (LCD). Preferably, at least two transparent OLEDs are arranged in a stacked configuration with one conventional OLED, each of the three OLEDs emitting light of a different bandwidth. The reflective electrode located behind the backlight also serves as a reflecting plate for the display. This arrangement enhances reflectivity and permits color sequencing in the transmissive mode, allowing all the components of a full color display (i.e. red, green, blue) to emit through the same pixel without the need for a color filter.
