20130086378 | PROXY SYSTEM FOR SECURITY PROCESSING WITHOUT ENTRUSTING CERTIFIED SECRET INFORMATION TO A PROXY - First communication units use a public key thereof certified by a certification authority on a PKI (Public Key Infrastructure), which is held by the first communication units in advance, and a secret key of the first communication units or delegation information generated by using secret information, as public key certificate, of the first communication units to thereby allow a proxy server to perform security processing, i.e. key exchange processing, authentication processing or processing for providing compatibility of encryption schemes, between the first communication units and a second communication unit on behalf of the first communication units. | 04-04-2013 |
20130128900 | PACKET PROCESSOR AND METHOD FOR PROCESSING PACKETS BY MEANS OF INTERNAL CONTROL PACKETS - A packet processor for processing an input packet includes an information generator for generating process control information for processing the input packet, an internal packet generator for receiving the input packet as an packet to be processed and adding the process control information to the packet to be processed to produce an internal packet, an internal packet processor for processing the internal packet supplied from the internal packet generator on the basis of the process control information added to the internal packet, and a packet transmitter for extracting an output packet from the internal packet processed by the internal packet processor to transmit the output packet. The packet processor can reduce the amount of communication between modules even when the packet processor includes plural modules. | 05-23-2013 |
20130136005 | DATA MANAGER FOR MANAGING STATION DATA OF COMMUNICATION DEVICES ON A TELECOMMUNICATIONS NETWORK - The data manager manages in a station data memory information on connecting communication devices including various numbers and signal processing conditions in correspondence with state information on the state of the connecting communication devices with the information on the communication devices classified into managing groups to update the state information associated with the information on the communication devices on a managing group-by-group basis. | 05-30-2013 |
20130142192 | VOICE COMMUNICATION APPARATUS FOR INTERMITTENTLY DISCARDING PACKETS - In a voice communication device for use on an IP network, a transmitter encodes voice information and assembles RTP packets with the encoded voice information inserted in a payload of the RTP packets to transmit a stream of the assembled RTP packets. RPT packets may intermittently be discarded at a rate of discarding from a stream of the RTP packets to be transmitted. The remaining packets will be transmitted to a destination. | 06-06-2013 |
20130177073 | VIDEO ENCODER AND DECODER APPARATUS DECIDING ERROR IN TRANSFORM COEFFICIENTS BETWEEN AN ORIGINAL IMAGE AND A PREDICTIVE IMAGE - A video encoder apparatus using a distributed video coding (DVC) includes a Wyner-Ziv frame encoder for forming a predictive image of a Wyner-Ziv frame on the basis of coded key frames, and determining, according to the fallibility of the transform coefficients of the predictive image with respect to the transform coefficients of an original image based on the Wyner-Ziv frame, the amount of error correction codes to be transmitted so as to transmit the error correction codes corresponding to the determined amount. When no errors are found between the transform coefficients of the original image of the Wyner-Ziv frame and the predictive image, information indicating that no errors are found is sent out instead of the error correction codes for the Wyner-Ziv frame in question. | 07-11-2013 |
20130182908 | VEHICLE TYPE IDENTIFICATION DEVICE - There is provided a vehicle type identification device including a detection section detecting, based on a vehicle region extracted from a captured image, on an imaging plane, a ground point, a first endpoint, a minimum ground clearance point, a second endpoint, and an upper endpoint of a vehicle, a vehicle width estimation section estimating a vehicle width in a real space based on the ground point, the first endpoint, and the minimum ground clearance point, a vehicle length estimation section estimating a vehicle length in the real space based on the ground point, the first endpoint, and the second endpoint, a vehicle height estimation section estimating a vehicle height in the real space based on the ground point, the first endpoint, and the upper endpoint, and a vehicle type identification section identifying a type of the vehicle based on the vehicle width, the vehicle length, and the vehicle height. | 07-18-2013 |
20130195274 | COMMISSION INFORMATION GENERATOR FOR MAKING PROCESSES ON COMMUNICATION PERFORMED BY ANOTHER COMPUTER - In a communicator in a communication system, a commission information generator for generating a commission parameter to make a process on a communication between communicators performed by another computer includes a first memory for storing a secret key and an encrypter for generating N number of the commission parameters, where N is a natural number, from a first to an N-th commission parameter. The encrypter regards a j-th shared key, where j is a positive integer equal to or less than N, out of the N number of shared keys as key information, encrypts a bit sequence representation of j-th partial information, associated with the j-th shared key, out of N pieces of partial information, and thereby generates a j-th commissioned parameter. | 08-01-2013 |
20130204401 | DEVICE COOPERATION CONTROL SYSTEM, TERMINAL, CONTROL APPARATUS, AND DEVICE COOPERATION CONTROL METHOD - A mobile device and a display apparatus are caused to cooperate. A user is instructed to do a predetermined action and the user holds and moves the mobile device. A motion of the mobile device is detected by the mobile device and the motion of the user is detected by the display apparatus. A pair of the mobile device and the display apparatus that detect the same action at the same time is caused to cooperate. | 08-08-2013 |
