CONTACT-FREE INTEGRATED CIRCUIT Russian patent published in 2005 - IPC

FIELD: information service technical aids.

SUBSTANCE: contact-free integrated circuit has to be functional analog of contact-free data descriptor working at different frequencies. The descriptors are used in software of electronic data turnover and for data protection. Peripheral part of contact-free integrated circuit that is used for contact-free communication with peripheral equipment through electromagnet radiation of central part. Peripheral equipment is responsible for data supply, data input and output according to preset protocol. Peripheral equipment has at least one photovoltaic semiconductor structure to transform incident electromagnet radiation of optical range to electric energy. The structure is connected to central part of contact-free integrated circuit at the side where power and data are applied. At the side of data output there are at least two voltage-controlled optically active structures to modulate reflected light radiation. Data exchange protocol corresponds to at least single-time scanning of photovoltaic and optically active structures by focused and modulated light beam. The structures are disposed on the path of the beam. Then radiation after being reflected by photovoltaic and optically active structures is subject to detection. Semiconductor laser of peripheral equipment can be used as light source.

EFFECT: improved design of disk drives.
