Abstract: An improved luggage handling and reconciliation system includes a biometrics data input device for obtaining biometrics data from a holder of luggage and a luggage identification document operatively connected to the biometrics data input device for generating device a luggage identification document containing biometrics data obtained by the biometrics data input device. The luggage identification document and biometrics data contained therein is used to reconcile luggage for determining whether luggage can be loaded onto an aircraft after checking to make sure that the holder of the luggage has boarded the aircraft. The luggage identification document is also used to reconcile luggage at an arrival airport so that the biometrics data is used to identify a person as the authorized owner of the luggage by comparing biometrics data input by the person with biometrics data stored on the luggage identification document.

Abstract: In a multi-antenna communication system using LDPC codes, a simple method is used to effectively improve the received quality by performing a retransmittal of less data without restricting applicable LDPC codes. In a case of a non-retransmittal, a multi-antenna transmitting apparatus (100) transmits, from two antennas (114A, 114B) , LDPC encoded data formed by LDPC encoding blocks (102A, 102B). In a case of a retransmittal, the multi-antenna transmitting apparatus (100) uses a transmission method, in which the diversity gain is higher than in the previous transmission, to transmit only a part of the LDPC encoded data as previously transmitted. For example, the only the part of the LDPC encoded data to be re-transmitted is transmitted from the single antenna (114A).

Abstract: An automatic retransmission request control system in OFDM-MIMO communication system. In this system, an ACK/NACK output part (320) of a receiver transmits, to a transmitter, a feedback information of positive or negative response based on the result of a cyclic redundancy check. An error data stream decision part (310) of the transmitter determines, based on the feedback information, a data stream that need be retransmitted, and a retransmission mode selection part (312) selects a retransmission mode from among (a) a mode in which to transmit the data, which are to be retransmitted, via the same antenna as in the previous transmission, while transmitting, at the same time, new data by use of an antenna via which no data retransmission is requested; (b) a mode in which to transmit the data, which are to be retransmitted, via an antenna via which no retransmission is requested, while transmitting new data via another antenna at the same time; (c) a mode in which to use STBC to retransmit the data via an antenna via which no retransmission is requested; and (d) a mode in which to use STBC to retransmit the data via all the available antennas.

Abstract: An apparatus and a method for providing access to a secured data or area includes at least two secure data modules which contain security data and other information and which belong to a particular security scheme and a dual module reader for reading data and permissions instructions contained on the secure data modules. The two secure data modules include an enabling module and an interrogatable module. The interrogatable module and the enabling module communicate with each other via a dual module reader. Communication between the two modules is allowed as long as the two modules are members of the same security scheme. A scheme is defined by suitable proprietary encryption keys for enabling communication and data transfer between the two modules belonging to a common scheme and for preventing communication and data transfer between two modules belonging to different schemes. The communication between the two modules provides an improved data security and access control system which eliminates the need for multiple passwords for various operations and also prevents problems associated with conventional access cards which are used in conjunction with passwords.
