An X-ray CT apparatus is provided with an X-ray tube current modulation pattern calculation means that calculates an X-ray tube current modulation pattern based on a 3-dimensional model of an object calculated based on a scanogram image of the object, start-up shape acquisition means that acquires a start-up shape of CT values of a predetermined region of the object or CT value time differences after injecting contrast agent into the object, time contrast curve prediction means that predicts a time contrast curve indicative of a time sequential change of contrast in a diagnostic portion of the object at each slice position at a scan time based on the acquired start-up shape of the CT values or CT value time differences, object 3-dimensional model modification means that modifies a 3-dimensional model of the object based on the predicted time contrast curve, and X-ray tube electric current modulation pattern modification means that modifies the X-ray tube electric current modulation pattern based on the modified 3-dimensional model of the object.

User interface objects are stored in a user interface object archive which is a database physically located in the shared library of an associated application program. In order to facilitate "localization", or preparation of an application developed in one language for use in an "area" or a locale which uses another language, the user interface objects are stored in a hierarchical locale tree within the archive. All objects are stored in the base or root of the hierarchy, but only those objects which require a translation are stored in an area associated with a more specific locale. At runtime, a complete collection of objects is assembled by starting at the desired locale and proceeding up the hierarchy level-by-level. Translated objects at lower levels of the hierarchy "override" those at higher levels so that the most complete translations of each object are obtained during this search. The user interface objects which are stored in an archive are actually created via a predefined "constructor" program, and, in order to allow newly-created user interface objects to use the predesigned constructor program, each user interface object is contained in a special "escort" object that interfaces with the constructor program. A user can edit an existing object, and change its class. This results in a new object of the new class being created. The existing attributes of the old object are transferred to the new object. Only the attributes known to the common base class or classes of the two objects are transferred. The new object is substituted for the old object, and the old object is deleted.

Method and apparatus for dynamic update of an existing object in an object editor

A method, system and program for testing programmatic interfaces by systematically exploring valid call sequences defined by a collection of subroutines with a collection of data. The subject invention does not explicitly write unit tests. Instead, it provides the tools to develop rules which model and verify the correct operation of software while leaving the complexities of test selection, execution, sequencing, coverage, and verification to an automated system. The number of test scenarios generated by the system depends upon cumulative execution time and is reliably independent of human effort.

Automated testing system

Object-oriented client-server facility (CSF) and networking service facility (NSF) interfaces implement communication between application programs residing in client and server nodes at a distributed services network. The CSF interface includes remote procedure call (RPC) objects for invoking and responding to service requests at the nodes and application programming interface (API) objects for transporting those requests between the nodes. However, the API objects only provide communication transports within a node. Accordingly, the API and RPC objects interact with dynamically-configurable protocol stacks within the NSF interfaces to complete the transport mechanism needed by an application program on the client node when accessing services on a remote server node.

In accordance with some embodiments, a graphical user interface on a portable multifunction device with a touch screen display includes: an application interface of an application that includes an application interface region with an edge; and a search input area for entering a search query for the application. In response to detecting a movement of an object on or near the touch screen display, the application interface region is translated on the touch screen display in a first direction. In response to the edge of the application interface region being crossed while translating the application interface region in the first direction while the object is still detected on or near the touch screen display, the edge of the application interface region is displayed, and the search input area is displayed in an area beyond the application interface region.

Methods and graphical user interfaces for conducting searches on a portable multifunction device

Computer-controlled test and measurement systems, including resources having multiple states and resources having multiple inputs, are modeled as data flow diagrams of topologically interconnected resources. A set of "tasks" are defined for changing the states of multiple-state resources and causing software resources to produce output data. Methods and apparatus, including internal and external task ordering rules, are provided to automatically interleave such tasks and implement input-ordering restrictions. Thereby, a sequence of tasks is produced to control the systems so as to assure valid data collection and protect physical resources from abuse. Data structures are illustrated for implementing the invention in an object-oriented programming environment.

A block diagram editor system and method is implemented in a computer workstation that includes a CRT and a mouse, graphics and windowing software, and an external communications interface for test instruments. The computer is programmed for constructing, interconnecting and displaying block diagrams of functional elements on the CRT. From prestored routines for each functional element, the software assembles and executes a program that emulates the functional operations of each element and transfers data from output from each element in turn to an input of a succeeding block, as determined by the block diagram configuration. The block functions include signal generating and analysis functions, and functions for control of various types of test instruments, which can be interactively controlled through the CRT and mouse. The computer converts desired outputs of the instruments into control settings and receives, analyzes and displays data from the instruments. Blocks can also be grouped into macroblocks.
