Abstract: A link table (28) showing a link relation between video data which are time reference data and log data which are number reference data is disposed. When the video data are deleted from a video recording ring buffer (23) or when the log data are deleted from a log recording ring buffer (26), a link data management unit (27) instructs either a number reference data recording and deleting unit (25) or a time reference data recording and deleting unit (22) to also delete the data which are the link destination of the deleted data with reference to the link table (28). Simultaneously, the link data management unit (27) deletes the link relation from the link table (28).

Abstract: A user authentication system of the present invention includes: a first wireless tag having first ID data about a user and a first antenna for transmitting the first ID data; a second wireless tag having second ID data different from the first ID data, and a second antenna, perpendicular to the first antenna, for transmitting the second ID data; a wireless-tag receiver for receiving the first ID data transmitted from the first antenna and the second ID data transmitted from the second antenna; and a use-permission determining apparatus for determining whether the ID data received by the receiver matches pre-registered ID data, and for determining, based on timing of or counts of receptions of the first ID data and the second ID data received during a predetermined period of time, whether use is permitted.

Abstract: An optimal control method and system of a group of elevator cars is provided. A matrix of origin halls and destination halls is used. In this matrix, each element is referred to as a mission unit. Also, mission groups are defined. Each of the mission groups has one or more mission units and is serviceable by one of the elevator cars. Further, a mission group set is defined as a set of the mission groups provided for the group of elevator cars. Then, the mission groups are dynamically allocated to the group of elevator cars, which produces effective traffic control of the elevator cars.

Abstract: A data comparison apparatus includes a cross-correlation table storing unit for storing degrees of match calculated for all possible combinations of two registered data, as a cross-correlation table, a comparison processing unit for comparing a currently-read registered data with an incoming data to be compared to calculate the degree of match between them, a comparison determination unit for comparing the calculated degree of match with a threshold value to determine whether there is a match between the currently-read registered data and the incoming data, and for forcedly finishing a further comparison process for remaining registered data if there is a match between the currently-read registered data and the incoming data, and a registered-data reading control unit for determining one registered data that is to be read next out of the registered-data storing unit, using the calculated degree of match and the cross-correlation table.

Abstract: A boxer doll has at least one articulate arm rotatably pivoted on a shaft provided in a shoulder portion of the body, and a pneumatic actuator operatively connected to the at least one articulate arm. An air supply tube has an inner end portion connected to the pneumatic actuator and an outer end portion, and a glove corresponding to the at least one articulate arm and being movable by a player is connected to the outer end portion of said air supply tube. An inertial pump disposed in said glove is connected through said air supply tube to said pneumatic actuator, for driving the pneumatic actuator in accordance with movements of the glove initiated by the player.
