The subject invention provides a unique system and method that facilitates classifying UI components abstracted from a computer based application in a strongly-typed manner based at least in part from a strongly-typed class framework. Methods included in the strongly-typed classes within the framework can correspond to one or more UI components found in the application. The UI components can be abstracted out and then the closest match between a UI component and a strongly-typed class in the framework can be found. Classes in the framework can be modified to create new strongly-typed classes. Once the UI components are classified in a strongly-typed manner, code can be created, albeit a lesser amount of code than otherwise would be required since the new strongly-typed classes can be derived from the framework.

The invention discloses a phase microscopic device for transmission type samples and a phase microscopic method. Based on a coaxial holographic light path, an amplified real image of a transmission type object, after being scanned by using a small hole, is taken as object light, scattering spots are formed on a target surface of a detector at a distance and interfered with plane waves in the same direction, the light intensity distributions formed when the scattering spots exist separately and the scattering spots are interfered with reference light are respectively recorded when the small hole is located at different positions, meanwhile, a situation that the reference light is not changed is ensured, and the light intensity distribution of the reference light is recorded once. A reproductive image (including amplitude and phase) with a size far larger than the size of the target surface of the detector is obtained in a mode of carrying out an iterative operation by using a computer. A reproductive image produced in the invention not only has the interference of zero-order images and conjugate images, but also can carry out phase microscopic imaging on a transmission type sample with a size far larger than the size of the target surface of the detector because a mode of small-hole scanning and prevention is adopted; and because of the introduction of the reference light, compared with a common iterative algorithm, the convergence speed is faster.

An automatic flusher employs an infrared-light-type object sensor to provide an output on the basis of which a control circuit decides whether to flush a toilet. After each pulse of transmitted radiation, the control circuit pushes a new entry onto stack if the resultant percentage of reflected radiation differs significantly from the last, and it includes in that entry's direction field an indication of whether the percentage change was positive or negative. Otherwise, the control circuit increments the existing top entry's duration field. From the numbers of entries in a row having a given direction and the sums of the values in their duration fields, the control circuit determines whether a user has approached the facility and then withdrawn from it, and it operates the flusher's valve accordingly.

A framework for extending a network management platform, including an object manager that retrieves an entire class hierarchy including any code or other functionality needed to retrieve data about a server or other network device (e.g., code needed to retrieve actual instances of an object of the class). The object manager holds the object hierarchy and initiates retrieval of actual instances of the object. The class hierarchies are maintained in plug-in type Object Providers. Newly developed network technologies are managed via managed objects defined by class hierarchies held by the Object providers.
