摘要： A beacon slot position control section of a radio communication apparatus constituting a radio network system which detects whether empty beacon slots are present in a beacon period. When an empty beacon slot is present before the period in which the radio communication apparatus transmits a beacon, a movable counter starts counting a specified number of super frames. When the count is completed, the radio communication apparatus transmits a beacon of the radio communication apparatus at the earlier empty beacon slot. Consequently, since the empty beacon slots are eliminated and the beacon period is compacted, even if the number of radio communication apparatuses joining the radio network system fluctuates dynamically, the radio communication apparatus can perform radio communication with high efficiency and less waste of consumed electricity.

摘要： The authentication server authenticated by a public key certificate at the time of authentication generates a difference parameter, transforms a template by the difference parameter to create a temporary registration template, and transmits the difference parameter to a tamper resistant device. The tamper resistant device generates a temporary parameter from the held transformation parameter and the difference parameter. A client terminal transforms feature using the temporary parameter, and generates temporarily-transformed feature. An authentication server receives the temporarily-transformed feature, and verifies whether the temporary registration template is in agreement with the temporarily-transformed feature.

摘要： When biometric information is registered, master helper data is created from user's biometric information and is saved in an IC card. When a user is registered in an authentication server, a password is created and registered in the server, the master helper data is converted to create helper data corresponding to the password, and the helper data is saved in an authentication terminal. When a user is authenticated, the authentication terminal generates an authentication password from the helper data and newly acquired user's biometric information, sends the generated authentication password to the authentication server, and the authentication server compares the authentication password with a registration password to authenticate the user.

摘要： A security system wherein, when a staff enters a building, a smart card carried by the staff is verified, and staff information inclusive of a staff number and fingerprint information is read from the smart card and is stored temporarily in a temporary storage file. When the staff logs on to a terminal, the fingerprint of the staff is read by a fingerprint input device (LS) and verified with the fingerprint information of the temporary storage file for verification. When the staff leaves the building, the staff number is read from the smart card the staff carries, and the corresponding staff information is erased from the temporary storage file. Security of a security object inside a security zone can be improved.

摘要： An axial flow fan wherein an impeller having a plurality of blades is supported rotatably in the cylindrical cavity portion of a venturi case so that an outer peripheral edge of each of the blades faces to an inner peripheral surface of the cavity portion with a small air gap. The outer peripheral edge of the blade is increased in thickness gradually toward a discharge port side of the venturi case from a suction port side of the venturi case. An peripheral edge portion of the blade at a suction port side of the venturi case is bent in the circumferential direction from a negative pressure surface side of the blade, so that the edge is small in thickness. An outer peripheral edge portion of the blade at a discharge port side of the venturi case has a portion extending circumferentially from a positive pressure surface side of the blade.

摘要： The present invention shortens the time required for watch list verification, and shortens the time required generally for the personal identification processing which includes watch list verification. In a personal identification system, a biometric information watch list comparison function (31) performs a first comparison of first biometric information in a traveler information DB (53), and biometric information on a biometric information watch list (52). Thereafter, a simplified alien immigration examination comparison function (41) performs a second comparison of the first biometric information in the traveler information DB (53), and second biometric information acquired by a biometric information acquisition function (62). As a result of the comparison, in the case where the difference between the time of the first comparison and the current time is within a previously defined time period, a terminal displays a first comparison result, and a second comparison result.

摘要： Provided is a radio communication method which can reduce the power consumption as compared to the conventional technique while realizing coexistence of a plurality of radio communication methods and can perform synchronization with a super frame of other radio communication device. The super frame has life confirmation slots (2820, 2830) through which radio communication devices of various modulation types should transmit tone signals. A radio communication device has a chance to judge whether one or more radio communication devices using a different modulation type exist or no such device exists in the vicinity. If no such device exists, the slot to be used by the radio communication device of the modulation method is reported as a time that can be used by a radio communication group of other modulation method.Thus, by confirming existence of an object in the vicinity by other radio communication device with which communication cannot be performed, communication can be performed by sharing the super frame.
摘要翻译：提供一种无线电通信方法，其可以在实现多种无线电通信方法的共存的同时与现有技术相比降低功耗，并且可以与其他无线电通信装置的超帧执行同步。超帧具有生命确认时隙（2820,2830），各种调制类型的无线电通信设备将通过该确认时隙发送音调信号。无线电通信装置有机会判断是否存在使用不同调制类型的一个或多个无线通信装置，或者在附近不存在这种装置。如果不存在这样的装置，则由调制方式的无线通信装置使用的时隙被报告为可以由其他调制方式的无线通信组使用的时间。因此，通过确认不能进行通信的其他无线通信装置附近的对象的存在，可以通过共享超帧来进行通信。

摘要： A frame such as a beacon in wireless communication, with a maximum MAC address, hop count, and maximum hop count, described therein is exchanged between nodes. All the nodes measure the number of hops from a node with the maximum MAC address, and exchange the maximum hop count (hmax) out of the numbers with each other. Hop count H(a,b) between arbitrary nodes a and b is expressed by H(a,b)≦H(a,max)+H(max,b)≦2*hmax, where hmax is a hop count from node (max) with the maximum MAC address to the farthest node. That is, the number of hops between two arbitrary nodes in the group is always 2*hmax or less. Herewith, a numeric value assuredly exceeding the maximum value out of the numbers of hops between nodes in an ad-hoc network can be propagated in the entire ad-hoc network.

摘要： A personal authentication method is provided for authenticating a user by cross-relation between an enrolled image and a verification image of biometric information of the user. Upon registration of the biometric information, the method generates a filter for scrambling the image and an inverse filter thereof, and applies the filter to the enrolled image generated from the biometric information to generate a registration template which is then stored to a memory. Upon authentication of the user, the method applies the inverse filter to the verification image generated from the biometric information collected from the user, and then verifies the identity of the user based on cross-relation between the verification image after application of the inverse filter and the registration template.
