Fiber Bragg Grating-Based Sensor device consists of a Bragg grating inscribed into a single mode optical fiber and operating on a wavelength of around 1550 nm. The fiber Bragg grating (FBG) is mounted inside a pneumatic cushion to be placed between the backrest of the seat and the back of the monitored person. Vibrations,i.e,dynamic strains transferred to the FBGs involve changes of the instantaneous Bragg wavelength values (proportional to the vibrations). Their detection with the interrogation system (with proper resolution and dynamic characteristics)provides information on breathing activity and heart rate.

A neural network is a processing device, either an algorithm, or actual hardware, whose design was motivated by the design and functioning of human brains and components thereof. The abilities of different networks can be related to their structure, dynamics and learning methods. There are many different types of Neural Networks, each of which has different strengths particular to their applications. ANN is used for their ability to represent non-linear relations makes them well suited for non linear modelling in control systems. Adaptation and learning in uncertain system through off line and on line weight adaptation Parallel processing architecture allows fast processing for large-scale dynamic system. Neural network can handle large number of inputs and can have many outputs.

This presentation on Optical Coherence Tomography(OCT) gives an insight into Signal Processing And Algorithm used in OCT. OCT is a medical imaging modality with 1-10 micro meter resolutions and 1-2 mm penetration depths. High resolution, sub surface non invasive or minimally invasive internal body imaging technique for structural and quantitative imaging. Signal processing intensive suited for embedded implementations using digital signal processors (DSP) and system-on-chip (SoC) application processors. Performance given in cycles per scanline and total number of scanlines that can be processed per second. Enables cross-sectional imaging of tissue microstructure in real time.

Blindness is caused by damage to clear structures in the eye, that allow the light to pass through, the nerves within the eye, the Optic nerve and brain. Various diseases of eye are
1) Retinitis Pigmentosa - Hereditary genetic disease. It is caused by degeneration of the retina. Gradually progress towards center of eye. Spares the foveal region. Tunnel vision results.
2) Macular Degeneration - This is also genetically related. Cones in macula region degenerate. Loss or damage of central vision. Common among aged people. Peripheral retina spared.
