There is provided a writing circuit of an electro-optical device having a plurality of scanning lines, a plurality of data lines, and a plurality of pixels disposed to correspond to intersections between the plurality of scanning lines and the plurality of data lines. Each of the first MIS transistors includes first L-shaped sidewalls each having an L-shaped cross-sectional shape, and each of the second MIS transistors includes second L-shaped sidewalls each having an L-shaped cross-sectional shape and outer sidewalls. The bidirectional event transmission sensor network has a structure of a super frame that includes at least one standby slot including the uplink section and the downlink section. The multimedia repository is queried by formulating a query using query-by-example, acquiring the descriptors and meta-descriptors for a repository multimedia item, generating a query descriptors if none of the same type has been previously generated, comparing the descriptors of the repository multimedia item and the query multimedia item, and ranking and displaying the results. The input and output addresses are based on a cryptographic key held by a service facility associated with the at least one access control cell. This allows entire groups of bits to be skipped by coding passes to which the coefficients do not belong.
