Abstract:
A data processing system includes a distributing device (22) that distributes edited advertisement data ED, formed by an editing device (21), and display terminal devices (32a) to 32c that display the edited advertisement data ED distributed to a first place in a predetermined territory. The display terminal devices are each provided with a first reader/writer 35 configured to read out from and/or write in an IC card 40 having stored memory identification data MID. The data processing system also includes a second reader/writer 52 installed in a second place of the predetermined territory and configured to read out from and/or write in an IC card 40. The data processing system also includes a hysteresis management device 23 that manages hysteresis data HD1, HD2 from the first reader/writer 35, correlated with the memory identification data MID, and hysteresis data HD1 from the second reader/writer 52, correlated with the memory identification data MID. The data processing system further includes a hysteresis analysis device 24 that correlates the hysteresis data HD1, HD2 for each of the memory identification data MID to generate analysis data D.
Abstract:
PROBLEM TO BE SOLVED: To provide an infrared ray communication system and an infrared ray signal detecting apparatus for suppressing the effect on infrared ray communication due to a prescribed of wavelength a near infrared ray emitted from a PDP. SOLUTION: An infrared ray signal transmitted from a remote controller 1 is made incident to a light detecting section 2A of a light detecting unit 2. A display apparatus 13 uses the PDP for a display element, which emits light with a strong peak at a prescribed wavelength of the infrared ray in the case of displaying a video image. This light is reflected in clothing of a user 14 or a surrounding reflector. The light detecting section 2A is provided with an optical filter for cutting off the light with a prescribed wavelength of the infrared ray by the PDP to suppress the incidence of the reflected light of the light emitted from the PDP onto the light detecting section 2A. The optical filter has a characteristic wherein the transmissivity is 80% or over for wavelengths longer than e.g., 900 nm, the transmissivity decreases for wavelengths of 900 nm to 800 nm, and the transmissivity reaches nearly 0% for wavelengths shorter than 800 nm. The effect of the optical filter is more eminent by lowering the light detecting sensitivity of the light detecting section 2A than the highest sensitivity. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a communication system ensuring high security regarding the management of an electronic key. SOLUTION: The communication system comprises a control device which controls a door locking mechanism for locking or unlocking the door according to electronic key information, and a management device connected to the control device through a communication network. The control device includes a first storage part for storing the electronic key information; a door lock control part which compares the electronic key information received from an electronic key device with the electronic key information stored in the first storage part and controls the locking and unlocking of the door according to the comparison result; and a deleting means which deletes the electronic key information from the first storage part according to a request to delete the electronic key information, which request is received from the management device. When receiving a deletion input, the management device searches for the address of the control device in which the electronic key information to be deleted is registered. The management device then transmits the received request to delete the electronic key information to the control device corresponding to the address. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To efficiently distribute coupons using advertisement media, and to measure advertisement effect in a state in which the coupons are used. SOLUTION: Advertisement video data watermarked with coupon ID data given to the coupons, respectively, are distributed and reproduced; an imaging unit 41 of a mobile telephone 40 images part of the video data provided by a display device 30; the coupon ID data are extracted from the imaged advertisement video data; and then the extracted coupon ID data are stored in a secure memory 48 storing the terminal ID data. Coupon ID data and terminal ID data transmitted by the mobile phone 40 are received, a coupon related to the coupon ID data is specified and refunded, and logs of the refunded coupons are transmitted to a coupon managing device 60, which manages the terminal ID data and refund log while relating them to the coupon ID data.

Abstract:
PROBLEM TO BE SOLVED: To minimize a load on a delivery server delivering advertisement data. SOLUTION: A relay server device 71 transmits, upon receipt of a status report from a display terminal device 32, the receiving result of status report to the terminal 32, and the delivery device 22 transmits, upon receipt of a status report from the relay server device 71, the receiving result of status report to the relay server device 71. The delivery device 22 transmits, when the reproduction schedule of advertisement data is changed, a change report of reproduction schedule to the relay server device 71 with the receiving result of status report. The delivery device 22 transmits, upon receiving an acquisition request of reproduction schedule after change from the relay server 71 after transmitting the change report, the reproduction schedule after change to the relay server device 71.

Abstract:
PROBLEM TO BE SOLVED: To provide an image transmission system whereby only a person himself/herself can securely view an image in the case of transmitting the image which the person himself/herself never desires someone to view via a network. SOLUTION: The image transmission system includes: one or more imaging apparatuses 100 each having a unique identification number and an encryption function for encrypting an imaged image and transmitting the encrypted image to the network 600; a key generating apparatus 200 for generating an encryption key to encrypt the image and a decryption key to decrypt the encrypted image for each imaging apparatus; a memory card 300 for recording the decryption key and the identification number of the imaging apparatus in cross-reference with each other; a browser 400 to which the memory card is connected and which has a decryption function for using the decryption key to decrypt the encrypted image and browses the image transmitted from the imaging apparatus via the network; and an authentication server 500 for authenticating the imaging apparatus accessible from the browser. Thus, the imaging apparatus can therein apply encryption processing to the image to enhance security. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To control the entrance and call of a visiting dealer, etc., and to deliver and receive an article for each dwelling unit regardless of the presence/absence of a resident in an apartment house. SOLUTION: An IC card having identification information recorded thereon is distributed to residents and dealers (registered dealers) allowed to enter. The IC card is used to transmit resident identification information and dealer identification information to a common entrance device 2, and the residents of the apartment house and the preregistered dealers are allowed to come into the apartment house. In each dwelling unit, the family identification information and dealer identification information are transmitted from the IC card to a intercom device 4 in a similar manner, and an entrance door lock is released for family members. Ringing tones may be changed between the registered dealers and dealers except the registered dealers, and the emission/non-emission of the ringing tones may be controlled. In addition, particular dealers among the registered dealers are allowed to use the house-to-house container boxes. COPYRIGHT: (C)2004,JPO
