A semiconductor device is provided configured to be electrically connected to another device by through silicon interconnect technology. The method and the apparatus prevent distortion of the mark or the space and improve a mark shape such that a recordingreproducing characteristic of the optical recording medium is improved. Hierarchical file repositories allowing binary upload, copying, and download for Internet store and forward capability. In embodiments of the invention, a context compression scheme similar to JBIG is applied, as well as an inverse scheme. Here, time X is the time when Out of Frame occurred. The sensor device may also generate derived data from at least a portion of the data indicative of at least one of activity, galvanic skin response and heat flow.
