    Describes a new system for recording and reproducing information on a dielectric material by selectively forming electret sites using the energy from modulated laser beams. The recorded information is read back by a specially constructed MOS FET playback head which detects the presence or absence of electric fields produced by stored charges in the electret sites on the tape. The dielectric materi... View full abstract»

    Finite element analysis is performed for the purpose of calculating the landing shift of electron beams due to thermal deformations of a shadow mask. For realistic finite element analysis, firstly the apparent thermal conductivity and the apparent elastic modulus are calculated, and the shadow mask is modeled as shell without slits. Next the finite element formulation is developed for transient th... View full abstract»

    A high-speed optical fibre data link is described that uses naturally sampled pulse width modulation (PWM) to achieve a low bandwidth overhead. The link is suitable for low-distortion transmission of full specification video and audio signals or any analogue signal with a bandwidth of up to 6.5 MHz over one kilometre of fibre View full abstract»

    Digital signal processing (DSP) techniques are becoming the standard for high quality digital sound on compact disks and digital audio tapes in consumer audio entertainment systems. Incorporating DSP technology to improve the quality of AM (amplitude modulation) and FM (frequency modulation) stereo radio reception assures high fidelity performance for all radio functions. The paper only deals with... View full abstract»

    The authors propose an architecture for an error correction circuit suitable for high-rate data decoding of the Reed-Solomon code. It features a multiple-error correction capability of 4 errors or 8 erasures. The operational steps for multiple-error decoding are reduced by a 4-stage pipeline and a superscalar processor of a Galois field. The experimental circuit's 16 Mbyte/s rate of data decoding ...

    A global image enhancement technique used to improve the visual quality of digitized photographs is described. The technique consists of two phases, viz., visual analysis and enhancement. In the visual analysis phase, approximate regions of an image that are visually significant are identified. Evaluation of visual significance is based on the features of focus, contrast, and texture which, in tur... View full abstract»

    In modern society, home and office automation become increasingly important and interesting. They not only provide better ways to transfer information within homes/offices and between homes/offices, they provide better time management too. These also improve the quality of our lives by automating some of the electrical home appliances such as light source, A/V equipment, computer, security device,... View full abstract»

    One of the most efficient image compression techniques investigated is the discrete cosine transform (DCT). The authors present a method where, through the use of pruning, the speed of implementation of the algorithm is dramatically increased. They describe its use in image compression. The advantage of the pruning algorithm in such cases being that, only a small proportion of the DCT values are r... View full abstract»
