    • Scrambling methods for scrambling ultra wideband (UWB) data are disclosed. UWB data (420) having payload data and non-payload data is scrambled (422, 424) by shifting a first bit string (412) a first number of bits, shifting a second bit string (410) a second number of bits, combining (414A - 414N) the first and second shifted bit strings, generating (418) scrambler control bits (416) from the combined first and second shifted bit strings, and scrambling (424) at least a portion of the UWB data responsive to the scrambler control bits. According to another aspect, UWB data is scrambled by scrambling payload data using a pseudo-random number generator having a seed set of multiple seeds having low seed correlation, each seed within the seed set having a predefined number of bits, and selective applying random frame reversion (428, 430) to non-payload data and/or to entire frame of data.

    • A small ultrasound diagnostic device is provided at a low cost that enables the appropriate control by a single power supply unit so as to give a predetermined transmission power to a driving waveform different for each mode without excess or deficiency and without affecting properties of the driving waveform. The ultrasound diagnostic device includes: an ultrasound generation unit (1) that transmits ultrasound; a waveform generation unit (2) that generates a single pulse or a burst pulse whose duty factor is variable in units of a time that is a period corresponding to a frequency outside a frequency band of the ultrasound generation unit (1) so as to drive the ultrasound generation unit (1); and a single power supply unit (3) that determines an amplitude of a driving waveform generated by the waveform generation unit (2). Thereby, an acoustic power of the transmitted ultrasound can be controlled without making the transmission amplitude variable.

    • A new predictive coding is used to increase the temporal frame rate and coding efficiency without introducing excessive delay. Currently the motion vector for the blocks in the bi-directionally predicted frame is derived from the motion vector of the corresponding block in the forward predicted frame using a linear motion model. This however is not effective when the motion in the image sequence is not linear. The efficiency of this method can be further improved if a non-linear motion model is used. In this model a delta motion vector is added to or subtracted from the derived forward and backward motion vector, respectively. The encoder performs an additional search to determine if there is a need for the delta motion vector. The presence of this delta motion vector in the transmitted bitstream is signalled to the decoder which then takes the appropriate action to make use of the delta motion vector to derive the effective forward and backward motion vectors for the bi-directionally predicted block.
    • 使用新的预测编码来增加时间帧速率和编码效率,而不引入过多的延迟。 目前,使用线性运动模型,从前向预测帧中的相应块的运动矢量导出双向预测帧中的块的运动矢量。 然而,当图像序列中的运动不是线性时,该方法无效。 如果使用非线性运动模型,则可以进一步提高该方法的效率。 在该模型中,增量运动矢量分别被添加到或从所得到的前向和后向运动矢量中减去。 编码器执行附加搜索以确定是否需要增量运动矢量。 传输的比特流中的该增量运动矢量的存在被发送到解码器,解码器然后采取适当的动作来利用增量运动矢量来导出双向预测块的有效的向前和向后的运动矢量。
