The door stop further includes an elongated rigid body pivotally attached to the first side member and the second side member, the elongated rigid member is configured to fit within the opening; a first groove extending a partial length of a thickness of the first member; a second groove extending a partial length of a thickness of the second member; a first tab extending from the elongated rigid body and configured to rest within the first groove; a second tab extending from the elongated rigid body and configured to rest within the second groove; and a pivot joint having a rod that extend through the first member, through the elongated rigid body, and through the second member.

Abstract: This invention concerns apparatus and a method for authenticating a subject using their eye as an identifying biometric, in particular the shape of their cornea. The apparatus comprises an image projection device to generate and project an image of a pattern, made up of plural discrete points, onto at least a part of the cornea of an eye of the person. An image capture device to capture an image of the pattern of plural discrete points, after reflection in at least a part of the cornea of an eye of the person. And, a computer processor to extract a data set defining the locations of the discrete points in the captured image. The method comprises capturing an image of an illuminated pattern, made up of plural discrete points, after reflection in at least a part of the cornea of an eye of the subject. Comparing the locations of the discrete points in the pattern of the captured image against the locations of the discrete points in the pattern of a reference image.

Abstract: An apparatus and method for validating the identity of a person using corneal imaging techniques. The method involves capturing an image of at least part of a person's cornea and deriving one or more geometric parameters. The geometric parameters are compared with corresponding reference geometric parameters for validation of the identity of the person.

Abstract: The present invention relates to a method and a data structure for defining a resource of a desired type within a resource management application. The method for creating a resource comprising steps for: selecting a catalog based on the desired type; identifying a template associated with the catalog; creating an initial instance of the resource; creating attributes associated with the resource based on definitions specified by the catalog and applying primary validations specified by the catalog; establishing relationships with the resource by applying constraints associated with the template and the catalog; and applying secondary validations associated with the catalog and the template. The data structure lends itself to being changed or augmented. This permits the modification or addition of resource type definitions without necessitating changes to computer program code in the resource management application.

Abstract: The present invention provides an interface in a first computer application system that can be utilized by other computer application systems to invoke the execution of an action (e.g. a functional process) on the first system. The first system can support multiple different actions each with distinct functionality. A single entry point in an externally accessible interface is used regardless of which action is invoked. Each invocation of the entry point includes two parameters. The first to designate which of the actions is to be invoked. The second provides for the referencing of data elements that can supply input arguments used during execution of the action. The single entry point is not exposed to the semantic of the supplied arguments. Therefore the action execution interface does not need to change when the semantic specific to any of the actions is changed or when a new action is added.

Abstract: An abradable seal comprises a plurality of hollow aluminosilicate spheres in a matrix of aluminium phosphate. The matrix of aluminium phosphate also has an aluminosilicate filler. The hollow aluminosilicate spheres have a diameter in the range of 400 to 1800 microns, preferably a diameter in the range of 800 to 1400 microns. The weight proportion of hollow aluminosilicate spheres in the abradable seal is 30% to 50%. The density of the abradable seal is 1.5 grams per cubic centimeter. The hollow aluminosilicate spheres in the aluminium phosphate matrix have a relatively high temperature capability of approximately 1300.degree. C. maximum. This makes the abradable seal better able to withstand the environment in the turbine of a turbofan gas turbine engine.
