  • Publication number: 20190160546
    Abstract: A surface-coated cutting tool includes a substrate and a coating film. The coating film includes an alternate layer. The alternate layer includes a first layer having a first composition and a second layer having a second composition. The alternate layer is formed by alternately stacking at least one first layer and at least one second layer. The first layer and the second layer each have a thickness not smaller than 2 nm and not greater than 100 nm. The first composition is expressed as TiaAlbSicN (0.25?a?0.45, 0.55?b?0.75, 0?c?0.1, a+b+c=1). The second composition is expressed as TidAleSifN (0.35?d?0.55, 0.45?e?0.65, 0?f?0.1, d+e+f=1). The first composition and the second composition satisfy a condition of 0.05?d?a?0.2 and 0.05?b?e?0.2.

  • Patent number: 7346192
    Abstract: An image input unit inputs an image including a user's face area to specify the user's gaze or face direction. A pattern generation unit generates an input pattern that can be compared with each dictionary pattern from the image. A dictionary unit previously stores a plurality of dictionary patterns each of which differently corresponds to the user's gaze or face direction. A pattern comparison unit respectively calculates a similarity degree between the input pattern and each of the dictionary patterns by comparing the input pattern with each of the dictionary patterns. A gaze detection unit detects the user's gaze or face direction based on the similarity degree.

  • Patent number: 7224835
    Abstract: An object recognizing apparatus can execute accurate object recognition based on dictionaries each created from a predetermined number of patterns, by computing a similarity between a subspace in each dictionary and a subspace created from input images. In this apparatus, images of a to-be-identified object obtained by an image input unit is expressed in the form of an input subspace by an inter-subspace-angle computing unit. The angles between the input subspace and the subspace of each dictionary stored in a dictionary storing unit is computed. An identifying unit identifies a to-be-identified object based on the angles (the degrees of similarity) computed by the inter-subspace-angle computing unit.

  • Patent number: 7127086
    Abstract: An image processing apparatus. A camera inputs an image of a face of a person to be recognized. A recognition area detection section generates a difference image between the input image and a predetermined pattern, and detects a recognition area whose value is above a threshold from the input image. An input data generation section converts the recognition area to a predetermined input data. A similarity calculation section calculates a similarity by comparing the predetermined input data with a predetermined dictionary data. A view position of the camera is located lower than a position of the face of the person. A direction of the optical axis of the camera represents an angle of elevation from a horizontal direction.

  • Patent number: RE39550
    Abstract: A security apparatus. A service is supplied to a user while maintaining the security of the service. A person discrimination section discriminates the user to be supplied the service. A user situation decision section decides whether the user is under a situation to use the service. An infringement situation decision section detects whether a non-user intrudes into a use area of the service in order to decide whether the security of the service is infringed. A service control section supplies the service to the user in case the person discrimination section discriminates the user, and controls a supply of the service if the use situation decision section decides the user is not under the situation to use the service or the infringement situation decision section decides that the security of the service is infringed.
