An integrated, multichanneled optical filter designed using the combination of optical devices (such as Ring resonators and optical waveguides) on a cantilever beam of silicon is described. This filter is actuated using MicroOptoElectroMechanical (MOEMS) system. When optical power is supplied to this filter, actuation takes place and due to which the refractive index of ring resonator changes due to the mechanical deformation. This change in the refractive index causes the output spectrum to change. Effect of this stress and strain on the beam has been taken into consideration. This study also involves frequency domain analysis of different Eigen frequencies and their response for various structural mechanics and electrostatics parameters. In order to accomplish this study different areas of Physics namely structural mechanics, Electrostatics, piezoelectric and Wave optics has been merged. This filter is very desirable because of its wide tuning range and its compatibility with IC based equipments used in current WDM networks.

Differential inverters are DC-AC bi-directional converters that are capable of stepping up/down and inverting the DC voltage in a single-stage. Single-stage conversion results in a more compact design, higher power density and lower cost compared to two-stage conversion. A differential inverter mainly consists of two converters. It can be buck, boost or buck-boost, according to the output requirements. Controlling of the two converters is done such that difference between their output results in an A.C voltage of required frequency. Here a differential inverter using buck converters is discussed. AC output voltage of required frequency with output voltage less than or equal to input voltage can be obtained by using this converter. The construction and controlling of this converter is very simple, which is one of the main advantages of this type of converter. Switching pulses to the converters are generated by using a control voltage which has frequency same as that of output. Two control voltages are needed which will be phase shifted by 180 resulting in 180 phase shift between the output of the two converters. As the name indicates final output is the difference of two converters. Also the magnitude of the output voltage below any input voltage value can be obtained by varying the magnitude of the control voltage.

Multispeed right angle friction gear which works on the principle of friction gear. This drives enable us to have a multi speed output at right angles by using a single output at right angles by using a single control lever. The design of the drive is based on the principle of friction, hence slip is inevitable, but in many cases the exact speed ratio is not of prime importance it is the multiple speed that are available from the drive that are to be considered. In this typical drive the power is transmitted from the input to the output at right angle at multiple speed and torque by virtue of two friction rollers and an intermediate sphere. The drive uses a singular control to effect the speed change, thereby making the operation of the drive extremely simple.

Natural fiber like coir is available in abundance all over the world. Properties of cement concrete can be improved with an addition of natural fiber derived from coconut covering. This covering fiber (coir) has excellent tensile strength and sufficient resistance to degradation. This fiber can be used as reinforcement in place of traditional steel reinforcement for building components like lintels over door and window openings, almirah shelves etc. The outer covering of fibrous material of a matured coconut, termed coconut husk, is the reject of coconut fruit. The fibers are normally 50–350 mm long. Due to its high lignin content, coir degradation takes place much more slowly than in other natural fibers. The fiber is also long lasting. The water absorption of that is about 130–180% and diameter is about 0.1–0.6 mm. The degradation of coir depends on the medium of embedment, the climatic conditions and is found to retain its tensile strength for long time.

In various telecommunication applications Digital Signal Processors are the key components in transferring the data between devices. The implementation of FIR filter on FPGA is based conventional methods increasing the need for considerable hardware resources, which in turn raises the circuit size and lowers the system speed. Most important operation performed in digital signal processing is multiply and Accumulation (MAC). Usually this operation is realized using novel hardware multipliers. The computations for sum of products can be performed more effectively using Distributed Arithmetic. This paper provides novel Distributed Arithmetic based technique to compute sum of products saving appreciable number of multiply and accumulation blocks and this consecutively reduces circuit size. In this technique multiplexer based structure is used to reuse the blocks so as to reduce the required memory locations. In this technique a Carry Look Ahead based adder tree is used to have better area-delay product. This brief presents efficient distributed arithmetic (DA)-based approaches for high-throughput reconfigurable implementation of finite-impulse response (FIR) filters whose filter coefficients change during runtime. Conventionally, for reconfigurable DA-based implementation of FIR filter, the lookup tables (LUTs) are required to be implemented in RAM and the RAM-based LUT is found to be costly for ASIC implementation. Therefore, a shared-LUT design is proposed to realize the DA computation. Instead of using separate registers to store the possible results of partial inner products for DA processing of different bit positions, registers are shared by the DA units for bit slices of different weight-age. Designing of FIR filter is done using Verilog and synthesized using Xilinx synthesis tool and Modelsim simulator. The power analysis is done using Xilinx X-power analyzer.
