摘要： Abstract The bunch by bunch feedback system is very important and indispensable in Upgrade of Beijing Electron and Positron Collider (BEPC II), which always runs under the conditions with multi-bunches and high beam current. However, the beam in the BEPC II ring could be unstable when the current increases because of the influence of high-order mode in high-frequency cavity and resistance of wall of the storage ring. Hence, the collision luminosity will be decreased and the feedback system, which consists of pick-up electrode, front-end electronics system, signal processing system, power amplifier and kicker, is required to suppress the beam instability. 500 MHz 500 MHz Power Splitter Frequency 500 MHz Doubler , Frequency 1.5GHz I Mixer A I1 GHz 500 MHz Bandpass Filter 1.5 GHz Amplifier 1.5 GHz Fig.1

摘要： A laser distance measuring apparatus and control method thereof includes an emitter, a first and second liquid crystal display module, a receiver, a condensing lens, and a control unit. The emitter emits measuring light. The control unit sets the first liquid crystal display module to a second state and the second liquid crystal display module to a first state to receive the reflected light. When the reflected light is larger than a predetermined value, the control unit adjusts a transmittance of the first liquid crystal display module until the reflected light is lower than the predetermined value, and calculates a distance value based on phase difference between the reference light and the reflected light.

摘要： A distance measurement method for use in a laser range finding device to measure a distance between the laser range finding device and a target is disclosed. The method comprises the following steps. A laser signal is sent to the target in a first time point. A reflected laser signal reflected by the target is then received. A digital signal having a plurality of signal values ranging from 0 to N is obtained by sampling the reflected laser signal with a sampling signal, wherein N is an integer larger than two. A maximum signal value among the signal values is obtained. The distance is calculated according to the first time point and a second time point where the maximum signal value is generated.

According to one aspect of the method, input components from a RGB model are used directly to calculate the down-sampled components of a YCbCr model. In an exemplary instance where average down-sampling and a down-sampling rate of “4:2:0” are used, the following equations are used to derive the down-sampled components of the YCbCr model: Y l ″ = ⁢ 0.29900 ⁢ R i + 0.58700 ⁢ G l + 0.11400 ⁢ B l Cb ″ = ⁢ - 0.04219 ⁢ ∑ i = 0 3 ⁢ ⁢ R l - 0.082815 ⁢ ∑ i = 0 3 ⁢ ⁢ G l + 0.12500 ⁢ ∑ i = 0 3 ⁢ ⁢ B l + 2 SP / 2 Cr ″ = ⁢ 0.12500 ⁢ ∑ i = 0 3 ⁢ ⁢ R i - 0.10467 ⁢ ∑ i = 0 3 ⁢ ⁢ G i - 0.02033 ⁢ ∑ i = 0 3 ⁢ ⁢ B i + 2 SP / 2 where Ri, Gi and Bi are three input components of the color conversion for the pixel i and “SP” represents a specified sample precision under the RGB model.

摘要： An improved audio compression scheme is provided. The scheme uses an excitation pattern to more efficiently provide audio signal compression. Under the scheme, an input signal is transformed to the frequency domain. Next, the excitation pattern corresponding to the transformed input signal is calculated. Bit allocation processing is then performed based on the excitation pattern. Frequencies are then coded based on the results of the bit allocation processing. Finally, bitstream packing is performed to generate the output coded audio bit stream. In one exemplary implementation, the audio compression scheme is implemented in an encoder.
