PROBLEM TO BE SOLVED: To provide a device establishing encryption communication to a communication apparatus for performing power line transmission by a simpler operation than before. SOLUTION: The device according to the present invention performs transmission setting for a first and a second communication systems having a function to superimpose a transmission signal on an electric power signal for communications. The device comprises: a power receiving plug for receiving electric power via an external power supply socket; at least one power supply socket for supplying the electric power received via the power receiving plug to the first and the second communication systems, a signal filter for shutting off a transmission signal propagating a power line between the power receiving plug and the power supply socket; an encryption key acquiring portion for acquiring an encryption key used for encryption communication between the first and the second communication systems or authentication from the first communication system connected to the power supply socket; and an encryption key transmitting portion for transmitting the encryption key acquired by the encryption key acquiring portion to the second communication system connected to the power supply socket.

PROBLEM TO BE SOLVED: To provide a method by which a means (network wiring) for interconnecting respective devices of a wearable computer is made lightweight and the movement of the body is not limited. SOLUTION: A superfine conductor is stitched in clothing as an interconnecting wire for the respective devices of the wearable computer in such a style that input/output(I/O) devices (102, 104, etc.), and a PC main body 107 are separated to form networks (903, 907, etc.), and thus a conventional troublesome cable is removed from the body to enable the natural movement of the body, thereby actualizing a high-reliability communication with the lightweight constitution.
Abstract:
PROBLEM TO BE SOLVED: To connect a mobile shopping system in a retail store without changing a conventional POS system at all, thus allowing payment using a POS system in the store, which is required because item information acquired from an item tag is supplied from a store system of the store, for a POS IF.SOLUTION: For a POS IF, if a retail store does not wish to change its store system in order to accept this payment (the change generally involves system integration and thus modification cost), a shopping-payment system may complete the payment by emulating an input directly using HW interfaces, such as a keyboard and a display, of the POS system in the store, although there is limitations in functions.
Abstract:
PROBLEM TO BE SOLVED: To provide a shopping/settlement management process which promotes utilization of a mobile shopping system by making prizes of manufacturers and retail stores won automatically.SOLUTION: Merchandise information is acquired from a merchandise tag 100 corresponding to the merchandise via a mobile phone 300 and, upon one or more acquisitions, shopping information is generated and transmitted to a shopping/settlement management system 500. In the case it is determined that a merchandise which is a prize object is included in shopping information under settlement which is acquired from the shopping/settlement management system 500, if the conditions specified by prize data match shopping information for the user ID out of said shopping information, a prize system 1600 performs prize processing and prize-winning processing for the prize data, notifies the mobile phone 300 and the shopping/settlement management system 500 of prize-winning, and the shopping/settlement management system 500 performs settlement processing.
Abstract:
PROBLEM TO BE SOLVED: To provide detailed information and personalized information on a merchandise article as additional information on two-dimensional bar cord and IC chip information.SOLUTION: In additional information to shopping information in mobile shopping, merchandise article information 760 is obtained from a merchandise article tag 100 by a mobile phone 300 and stored in the mobile phone by performing a bookmark operation in addition to a purchase operation. At the same time, shopping information 430B is transmitted to a shopping/settlement management system 500 and stored in a bookmark DB 1480 by extracting bookmark information. After that, when shopping information is obtained by reading the bookmark information stored in the mobile phone by allowing a merchandise tag to include a code corresponding to relative merchandise article information (such as promotion and campaign) as additional information 340, relative merchandise article information is also obtained and presented to a client.

PROBLEM TO BE SOLVED: To modify a frequency of a video clock, without affecting the quality of display. SOLUTION: A method to decrease the video clock frequency includes steps of: detecting momentum for lowering the video clock frequency; lowering the video clock frequency within a range in which a circuit using the video clock, such as a PLL (Phase-Locked Loop) circuit can track the frequency fluctuation; and repeating the step for lowering the video clock frequency, until the video clock frequency modified with the step reaches a predefined frequency.

Abstract:
PROBLEM TO BE SOLVED: To change the frequency of a video clock so as not to affect display quality by providing a step of lowering the frequency of the video clock and a step of repeating this step until the changed frequency of the video clock becomes a prescribed frequency. SOLUTION: First of all, the timing to change the frequency of the video clock (Vclk) is detected (S110). Next, it is judged from the name of an application on a window displayed on a screen whether the frequency of Vclk is changed or not (S120). Next, when changing the frequency of Vclk, there are the cases of increasing and decreasing the frequency and corresponding to the cases, processing is made different (S130). Therefore, it is reported to a user to lower the frequency of Vclk (S140). Then, processing for actually lowering the frequency of Vclk is executed (S150), it is judged whether or not processing is finished and when not finished, it is returned to S110 again (S170).
Abstract:
PROBLEM TO BE SOLVED: To make it possible to carry out an analysis of purchase behavior of a customer in a real store and perform sharp focusing of a targe customer of promotion and timely distribution of promotion information.SOLUTION: In a settlement by bookmark in mobile shopping, merchandise article information 760 is obtained from a merchandise article tag 100 by a mobile phone 300, and stored in the mobile phone by performing a bookmark operation in addition to a purchase operation. At the same time, shopping information 430B is transmitted to a shopping/settlement management system 500 and stored in a bookmark DB 1480 by extracting bookmark information. Then, after shopping information is prepared by reading the bookmark information stored in the mobile phone, when transmitting it to the shopping/settlement management system, campaign information applicable to the mobile phone is obtained by verifying the bookmark information, and settlement information is prepared and transmitted to a store system 700. The store system refers to a merchandise article information history DB 770 and performs settlement based on the merchandise article information which matches a bookmark date of the settlement information.
Abstract:
PROBLEM TO BE SOLVED: To detect a watermark image described in a printed matter at precision higher than in the conventional case and to display the watermark image so that it is easy to make a user recognize it. SOLUTION: This display device which extracts and displays the watermark image described in an object to be photographed is provided. The display device is provided with a first photography part which generates a first image by photographing the object to be photographed, a second photography part which generates a second image by photographing the object to be photographed including a watermark image preliminarily described in the object to be photographed and which is not detected by photography of the first photography part and a watermark image extraction part which extracts the watermark image from the second image based on the first and second images.
