New battery management system for multi-cell li-ion battery packs

This paper proposes a new battery management system （BMS） based on a master-slave control mode for multi-cell li-ion battery packs. The proposed BMS can be applied in li-ion battery packs with any cell number. The whole system is composed of a master processor and a string of slave manager cells （SMCs）. Each battery cell corresponds to an SMC. Unlike the conventional BMS, the proposed one has a novel method for communication, and it collects the battery status information in a direct and simple way. An SMC communicates with its adjacent counterparts to transfer the battery information as well as the commands from the master processor. The nethermost SMC communicates with the master processor directly. This method allows the battery management chips to be implemented in a standard CMOS （ complementary metal-oxide-semiconductor transistor） process. A testing chip is fabricated in the CSMC 0.5 μm 5 V N-well CMOS process. The testing results verify that the proposed method for data communication and the battery management system can protect and manage multi-cell li-ion battery packs.

Design and implementation of GM- APD array readout circuit for infrared imaging

Based on an avalanche photodiode（ APD） detecting array working in Geiger mode（ GM-APD）, a high-performance infrared sensor readout integrated circuit（ ROIC） used for infrared 3D（ three-dimensional） imaging is proposed. The system mainly consists of three functional modules, including active quenching circuit（ AQC）, time-to-digital converter（ TDC） circuit and other timing controller circuit. Each AQC and TDC circuit together constitutes the pixel circuit. Under the cooperation with other modules, the current signal generated by the GM-APD sensor is detected by the AQC, and the photon time-of-flight（ TOF） is measured and converted to a digital signal output to achieve a better noise suppression and a higher detection sensitivity by the TDC. The ROIC circuit is fabricated by the CSMC 0. 5 μm standard CMOS technology. The array size is 8 × 8, and the center distance of two adjacent cells is 100μm. The measurement results of the chip showthat the performance of the circuit is good, and the chip can achieve 1 ns time resolution with a 250 MHz reference clock, and the circuit can be used in the array structure of the infrared detection system or focal plane array（ FPA）.

Design of Si-bipolar Monolithic Main Amplifier IC for Optical Fiber Receivers

A broadband amplifier with transadmittance and transimpedance stages is designed and two types of improved AGC amplifiers are developed on the base of theory study. Making use of the basic amplifier cells, a main amplifier IC for optical-fiber receivers is deliberated. By computer simulating the performances of the designed main amplifier meet the necessity of high gain and wide dynamic range . They are maximum voltage gain of 42 dB, the bandwidth of 730 MHz,the input signal( V p-p )range from 5 mV to 1 V,the output amplitude about 1 V, the dynamic range of 46 dB. The designed circuit containing no inductance and large capacitance will be convenient for realizing integration. A monolithic integrated design of 622 Mb/s main amplifier is completed.

The Current Metamorphosis of Instrumental Rationality

In the first part, the concept of instrumental reason is defended. Although we live in the age of pluralism, in which a tendency prevails to put all types of rationality on the same plane, there is a rationality that has a unique position： the instrumental rationality. The article then examines Luk^ics＇s roots of this concept and its elaboration by Adomo and Horkheimer. The second part refers to the current transformation of instrumental reason that these authors could not register. Instrumental reason changes so that it can connect several seemingly incoherent elements： postmodern non-objectivity, social and ecological normativity, and reified imperatives of capitalism. This formation is here called over-instrumental instrumental reason. In conclusion, the article deals with the question of how its non-instrumental component to exempt from its instrumental ones.

Democratic Barricades： The Presence of Radio in the Resistance to the 1964 Military Coup

This paper articulates two great discussions within the history of this country： the discussions about the circumstances prior to the military coup and the role of the radio media in the political context of the conflict. Individually, each of these aspects will allow us a reflection over different points of view here articulated in a sociocultural approach. We have, thus, organized this discussion based on two main themes. We will start with the ＂Campanha da Legalidade＂ （Campaign for Legality）, the occasion which congregates both themes, and then we will discuss both the historical context of the 1964 military coup and the role of the radio media and its strong social and political presence.

Towards active plasmonic response devices

Given the interdisciplinary challenges in materials sciences, chemistry, physics, and biology, as well as the demands to merge electronics and photonics at the nanometer scale for miniaturized integrated circuits, plasmonics serves as a bridge by breaking the limit in the speed of nanoscale electronics and the size of terahertz dielectric photonics. Active plasmonic systems enabling active control over the plasmonic properties in real time have opened up a wealth of potential applications. This review focuses on the development of active plasmonic response devices. Significant advances have been achieved in control over the dielectric properties of the active surrounding medium, including liquid crystals, polymers, photochromic molecules and inorganic materials, which in turn allows tuning of the reversible plasmon resonance switch of neighboring metal nanostructures.
