Atmospheric free space optical communication is one of the new techniques in short-haul broadband applications. An innovative 1.25Gbps FSO communication system with vertical cavity surface emitting laser and position sensitive detector is presented based on system power attenuation analysis.
Basing on the reflection spectrum of a FBG filter, the impacts of intraband coherent crosstalk and intraband incoherent crosstalk in an OXC based on demultiplexers using fiber Bragg grating (FBG) filters, deduces the system power penalty and discusses in detail the dependence of system degradation on the coupling coefficient, grating length and polarization matching factor, etc.
Through the analysis of system power penalty using System View software, the result can be obtained that using the compensation system mentioned above, the quality of the output signal can be improved greatly.
The main characteristics of the rotor model, control and excitation system, power and transmission system, measurement system, data acquisition and processing system, safety and warning system, display system and master console are briefly described.
Based on the principle of system power cycle and characteristics of Freon power generation system, the model for low temperature waste heat generating was constructed. The evaporator, condenser and steam turbine model were designed as well.
From the system power, micro-computer measurement and control, system hardware and system software of view, the paper emphatically expatiates on the reliability design of HT6L_1-400Z/1140 combined magnetic control station based on PLC.
According to the medicine clinical practice request, the article introduced inserts the type hardware platform based on Tristar ARM7 chip S3C44B0X the development, including connection electric circuit and so on system power source, CPLD, SDRAM and FLASH, USB, liquid crystal screen design.
Through analyzing system powerconsumption,many methods which depress system power consumption have been putforward;
The basic characteristics of Garfield, and its structure especially its power management unit are introduced. On the basis of the working mode design of CPU and peripheral device module, the system power states, transition process between these states and state transition scheme have been worked out.
In the aerospace ground observation TV camera system with limited space available, CPLD design schemes are adopted to lower system power consumption, shorten R & D cycle and improve system reliability.
Converging plasma plume size, substrate heat flux, and enthalpy profiles are also shown to be a strong function of applied system power.
As an upper bound based on optimistic injection and direct conversion efficiencies, we find the D-3He satellite system power output attaining at best 1/3 of the parent fusion power.
This paper presents a novel built-in current sensor that uses two additional power supply voltages besides the system power supply voltage, and that is constructed by using a current mirror circuit to pick up an abnormal IDDQ.
We extend the notion of a race condition for IBM Shared Memory System POWER/4, taking into consideration its noncoherent caches, and propose techniques for detection of false sharing problems.
