  • Patent number: 12146855
    Abstract: A detector that detects an internal state of a plate-shaped object including a fiber-reinforced resin. The detector includes an exciter that applies, to a surface of the object, ultrasonic vibrations of Lamb waves, in a selected frequency range where only a zero-order fundamental wave symmetric mode and a zero-order fundamental wave asymmetric mode of the Lamb waves appear, a vibration detector that detects the applied ultrasonic vibrations propagating in the object, and an internal state estimation calculator that estimates the internal state of the object, by obtaining a propagation time of the ultrasonic vibrations propagating in the object corresponding to each frequency of the Lamb waves, based on the detection result of the vibration detector, estimating the internal state based on a delay time of the propagation time relative to a reference propagation time of the object for each frequency in the selected frequency range, and outputting the estimated internal state.

  • Publication number: 20240304287
    Abstract: A recommendation data generation apparatus (2000) acquires material specification information (10) representing a material specification of a material (60) and physical property information (20) representing a physical property of a product (70). The recommendation data generation apparatus (2000) generates a self-organizing map (30) by using the physical property information (20). Each node on the self-organizing map (30) is assigned a position in a map space and a physical property vector representing a physical property. The recommendation data generation apparatus (2000) assigns each node a specification vector representing the material specification by using the material specification information (10). The recommendation data generation apparatus (2000) acquires target information (80) representing a desired physical property, and detects a target node to which a physical property vector matching that physical property is assigned.

  • Patent number: 8038060
    Abstract: Techniques for providing an ID image on a print medium are disclosed. Commodity information on a commodity settled in a store is received from a store terminal installed at the store. ID images, defining ID information in a frequency domain and accompanied by attribute information that is used by the store terminal to decide whether or not each of the stored ID images is to be printed, are stored. A correspondence between the commodity information and the stored ID images is also stored. ID images corresponding to the received commodity information from the stored ID images using the stored correspondence are then retrieved. An attribute list, which registers the attribute information of the stored ID images that is used by the store terminal to decide whether or not each of the stored ID images is to be printed, is stored. Thereafter, only the retrieved ID images which have been decided to be printed based on the stored attribute list are transmitted.
