In this paper, a new CMOS design methodology is proposed to implement CMOS neuromorphic chips which imitate the ON brisk transient ganglion cell (GC) set of rabbits' retinas. The measurement results on the fabricated CMOS neuromorphic chip are consistent with the biological measurement results. Thus, the biological functions of the chip have been successfully verified. It can be used to understand...
A bionic eyeglass is proposed in this paper, a device that helps blind and visually impaired people in basic tasks of their everyday life by converting visual information into speech. The indoor and outdoor situations and tasks have been selected by a technical committee consisting of blind and visually impaired persons, considering their most important needs and potential practical benefits that...
Recent advances in homologue recombination based bacterial artificial chromosome (BAC) engineering have greatly simplified knock-in, knock-out and random integration based transgenic mice technologies. Despite the rapid advances in ldquowetrdquo BAC engineering, efficient bioinformatics tools for choosing the appropriate BACs and designing the targeting construct with gene specific homology arms has...
The CNN literature contains several papers about how to use the genetic algorithms for template tuning. This paper shows a possible CNN-UM implementation of the control algorithm of the genetic algorithm in a special fine-grained parallel version. The interesting of the analogic mapping is the different set of operators, which can be evaluated fast and efficient on the CNN-UM platform. The rational...
In spite of the impressive advances related to retinal prostheses, there is no imminent promise to make them soon available with a realistic performance to help navigating blind persons. In our new project, we are designing a Bionic Eyeglass that is providing a wearable TeraOps visual computing power to advice visually impaired people in their daily life. In this paper the system aspects are explained...
The paper focuses on the input transformation for retinal implants. It describes a novel retina model, based on neurobiological measurements. Our modeling approach is neuromorphic, however the primary motivation is to derive an algorithmic skeleton from the animal retina measurements. The on-line, real-time implementation of the algorithm is given for an off-the-shelf stand-alone system, called Bi-I
