    Abstract: An audio processing system for injecting left and right channel audio signals with a signal having a fundamental frequency component that is half the frequency of the highest amplitude low frequency component in the left and right channel audio signals. The left and right channel audio signals are combined to form a monaural signal that is low pass filtered and applied to a demodulator circuit. The demodulator circuit generates a control signal having a frequency that is half the frequency of the highest amplitude frequency component in the signal at the output of the band pass filter. The control signal varies the phase of the signal at the output of the band pass filter according to the polarity of the control signal. The resulting signal is selectively added to the left and right input signals. In order to prevent the audio processing circuit from producing annoying artifact when the audio signals are vocally generated, a voice detector determines that the input signals are from a vocal source and then disables the audio processing circuit. The voice detector operates by comparing the monaural (left plus right) signal to a differential signal (left minus right). Vocal source material has a relatively higher monaural signal while a musical source has a relatively higher differential signal.

    Abstract translation: 一种音频处理系统，用于使用具有在左右声道音频信号中的最高幅度低频分量的频率的一半的基频分量的信号来注入左声道和右声道音频信号。 左声道和右声道音频信号被组合以形成低通滤波并应用于解调器电路的单声道信号。 解调器电路产生具有在带通滤波器的输出处的信号中的最高幅度频率分量的频率的一半的频率的控制信号。 控制信号根据控制信号的极性改变带通滤波器的输出处的信号的相位。 所得到的信号被选择性地添加到左和右输入信号。 为了防止音频处理电路在声音产生时产生烦人的假象，语音检测器确定输入信号来自声源，然后禁用音频处理电路。 语音检测器通过将单声道（左加右）信号与差分信号（左减右）进行比较来进行操作。 声源材料具有相对较高的单声道信号，而音源具有相对较高的差分信号。

    Abstract: Methods and apparatuses for a magnetic tunnel junction (MTJ) which can be used in as a magnetic random access memory cell are disclosed. The MTJ comprises a free layer and an insulator layer. The MTJ further comprises a pinned layer with a first region, a second region, and a third region. The second region is of a first length and of a first thickness, and the first region and the third region are of a second length and of a second thickness. A ratio of the first thickness to the second thickness may be larger than 1.2. A ratio of the second length to the first length is larger than 0.5. The first thickness may be larger than a spin diffusion length of a material for the pinned layer. So formed MTJ results in increased tunneling magnetic resistance ratio and reduced critical switch current of the MTJ.

    Abstract: A computer includes a motherboard with a signal receiving port and a switch circuit. The switch circuit includes a force sensing module and a transistor. The transistor includes a first terminal connected to the force sensing module, a second terminal connected to a power source, and a third terminal connected to the signal receiving port. When there is a pressure applied to the force sensing module, the force sensing module outputs a first driving signal to turn on the transistor and enables the computer to maintain its current power on or off state. When there is no pressure applied to the force sensing module, the force sensing module outputs a second driving signal to turn off the transistor and switches on or off the computer.
