TL;DR: In this paper, the authors proposed a method and an apparatus for protecting data on a storage medium by encrypting the data to be recorded on the storage medium with a password, which is done by using the key data generated separately from the password, and therefore feasible to prevent the password from being analyzed by decoding a cipher text.

TL;DR: In this paper, the authors propose an approach to support increase in efficiency of reading management information being recorded in an optical disk by storing management information in the history information storage of an information reproducing device.

TL;DR: In this paper, a single-chip Bluetooth transceiver in 018/spl mu/m CMOS integrates a direct VCO modulation transmitter and 15MHz-IF receiver to reduce power consumption and cost.

TL;DR: Time-domain analog and digital mixed-signal processing (TD-AMS) is presented, and is a solution better suited to implementing a system on chip including functions for which high computational accuracy is not required, such as error correction, image processing, and machine learning.

TL;DR: In this article, an autoadjusting electron microscope is described, in which an image processor derives a third image constituting an analysis image from first and second images of a specimen by Fourier-transforming the first-and second-images, computing a phase variant image from the Fouriertransformed first-image and second-image images, and then Fourier transforming or inverse Fourier transforming the phase-variant image to obtain the third image.
