摘要： The present invention relates to an electronic device that suppresses reduction in reception sensitivity and occurrence of distortion when IC cards are used while stacked. A loop antenna equipped on the IC card has up to four turns, and is designed so that one turn, for example, has a first linear portion, a first curved line portion, a second linear portion, and a second curved line portion. When two electronic devices having a first loop antenna and a second loop antenna, respectively, are stacked onto one another, the corners of the loop antennas do not overlap. For example, the corner formed by first curved line portion and the second linear portion of the first loop antenna is overlapped with the first curved line portion of the second loop antenna. The first and second loop antennas are shaped such that when two electronic devices are stacked, their respective loop antennas are superimposed in the opposite direction so that the corners are not overlapped and the amount of overlap as a whole is reduced. The present invention may be applied to an IC card for receiving/transmitting data under non-contact state.

摘要： An IC card and an IC card system for transmitting a signal modulated with a desired data sequence. In the IC card, a reference signal having the same frequency as a carrier of a transmission signal received by an antenna and phase-synchronized with the carrier is formed, and a response data sequence corresponding to the desired data sequence is sent out from the antenna by modulating the reference signal with the response data sequence in a phase shift keying manner.

摘要： The recognition pattern device is intended to improve the recognition ratio. In a pre-processing unit 3, an input pattern is prepared based on the image taken from a video camera 1. Then, in a comparing processing unit 4, the input pattern is compared with a basic pattern stored in a function learning storing unit, and the deformed amount of the input pattern to the basic pattern is calculated. Thus, in a deformed amount analysis unit, the deformed amount is analyzed. Finally, in a person's information learning storing unit, on the basis of the above result, the standard pattern stored therein is regenerated.
