  • Publication number: 20240094369
    Abstract: A reading apparatus includes a mechanism to move an antenna between first and second positions, and a controller configured to: (a) control the antenna to transmit radio waves to wireless tags each attached to an object when the antenna is between the first and second positions; acquire, from response waves, information registered in each tag and indicating attributes of the object and the tag, and signal values of the response waves; and calculate an estimated position of each tag and a reliability level thereof based on the values. When the level of the position of a tag is less than a threshold or when the information of a tag indicates an attribute that can affect radio communications, the controller performs step (a) again, acquires signal values of response waves received from the tag, and calculates an estimated position of the tag and a reliability level thereof based on the values.

  • Patent number: 11663210
    Abstract: An embodiment of a data pattern analysis optimizer includes a time sequence data memory, an estimator, a grouping unit, and a time sequence pattern extractor. The time sequence data memory stores a plurality of time sequence data made from items in time order. The estimator estimates the upper limit of the total number of types of time sequence patterns present in the time sequence data at a rate higher than a minimum support level, based on a respective rate of presence of each item, wherein each of the time sequence patterns present in the time sequence data is a predefined number of items. In case that the estimated upper limit exceeds an upper limit of the number of types of time sequence patterns as a maximum processing load to a computer, the grouping unit groups a plurality of time sequence data into sub-groups, based on a group of items having the increased number of items and gives the estimator instructions to perform estimation.

  • Patent number: 10769534
    Abstract: An evaluation target of interest extraction apparatus of one embodiment extracts a plurality of items for each piece of text information. When the items include an item which matches an evaluation target expression or related expression, the apparatus allocates the evaluation target expression or that of the related expression to the text information as an evaluation target item. The apparatus distinguishes a class from a change in numeric information related to the evaluation target item, and allocates the class to the text information. The apparatus generates a class-attached transaction including the evaluation target item, the items, and the class. The apparatus discovers a pattern from a set of the transactions.
