The variable time delay and the packet loss degrade the performance of Internet based teleoperation system seriously
even make the system unstable. To overcome the trouble
an idea that using CARIMA model of the linearized slave robot to design a controller based on the Generalized Predictive Control (GPC) method is proposed in this paper. We place the GPC controller at the remote site. First of all
The CARIMA model of the linearized slave robot is derived. Secondly
a GPC controller is designed at slave site to generate the redundant control information to diminish the influence of the packet loss and the large time delay in the internet to the system. Moreover
in order to solve the problem caused by the variable time delay
the reference information signed with time stamp is used and fedback to the operator
so the operator can predict the next round trip time delay(RTT) according to the preceding RTT we got. Finally
stability condition is achieved. Simulation results show that these strategies can dynamically compensate for the variable time delay and reduce the performance degradation induced by packet loss.

Based on the CROSSBAR network (CN) and the BANYAN network (BN)
8 matrix optical switch
two new rearrangeable nonblocking constructions of extended BANYAN network (EBN) are proposed for implementing 88 optical matrix switch. The interconnection characteristics of these two types of rearrangeable nonblocking EBN were studied
optical insertion loss of 4.6 dB
and the logic program for driving switching units was provided. The calculated insertion loss was 3.3 dB for 88 optical matrix switch. Silica waveguide 88 matrix optical switch was designed and fabricated according to the calculated results. The silica waveguide propagation loss of 0.1 dB/cm and waveguide-fiber coupling loss of 0.5dB/point were measured. With the fabricated 87times
cross-talk of -38 dB
polarization dependent loss of 0.4 dB
averaged switching power of 1.6 W
and switching time of 1 ms were achieved. A basic agreement between experimental results and theoretical calculated values was achieved.

This paper presents a new wavelength-selective switch by combining silicon micromaching and microassembly techniques. The 18 wavelength-selective switch (WSS) based on micro electro mechanical systems (MEMS) technology is proposed and fabricated with micro electromagnetic actuators
8 WXC prototype node is implemented by using 18 WSSs as building elements. The working principle and the configuration of the micro electromagnetic actuator are illuminated. By analysis
reflecting prisms and narrow-band thin films filters. And a 8
the property suits for the application when the inputs are 2V
and the best fiber-to-fiber insertion loss 5dB is gotten.

High power laser diode array with an emission wavelength of 1064nm is presented. The epitaxial structure is an InGaAs/GaAsP strained-compensated single-quantum well structure. The modules CW output power can reach to 56.5W at current of 80A. Because the heat capacity of st rather shorter pulse duration and lower duty cycle
the average driving power in the laser chip is quite low
so the heating effect cemiconductor laser is very small
using pulse injection can reduce temperature rising significantly. Aould be neglected. The definite relation between lasing wavelength and chip temperature is developed. The temperature drift coefficient is 0. 45nm/K 2008 SPIE.
