Linked zones define the temporal and spatial relationships among multiple zones of a surveillance area, and are used to model an object's disappearance from one zone, for potential reappearance at another zone. One or more zones are defined within each camera's field of view. Two zones are linked if an object that disappears from one zone is capable of appearing in the other zone. Each link has an associated delay parameter or function that characterizes the time delay, if any, between a disappearance and subsequent appearance. For each zone, a set of other zones that are linked to this zone is maintained. When an object disappears from a zone, the set of other zones that are linked to this zone is used to reduce the search space for object appearances corresponding to this disappearance. When the corresponding object appearance is found, the tracking function is handed-off to the tracking module associated with the zone in which the object appeared.

Verifying application security vulnerabilities includes receiving a source code to analyze, performing a static analysis using the received source code and generating a vulnerability call trace for the received source code. Responsive to a determination that all static analysis results are not validated, mock objects are generated using the vulnerability call trace and a unit test is created using the generated mock objects. The unit test is executed using the generated mock objects and responsive to a determination that an identified vulnerability was validated; a next static analysis result is selected. Responsive to a determination that all static analysis results are validated, results and computed unit tests are reported.

Computer code for a mock object is automatically generated and used in testing computer program code. Interactions with a method of an object that is described by the computer program code are captured. From the captured interactions, mock code that creates a mock object is automatically generated. The mock object mimics the captured interactions. Subsequently, test code, which has at least some of the computer program code and mock code, is executed to enable testing of the computer program code.

A method of providing user interaction with a computer representation of a simulated object, where the user can control the object in three dimensions. The method can provide for two distinct states: a “holding” state, and a “released” state. The holding state roughly corresponds to the user holding the simulated object (although other metaphors such as holding a spring attached to the object, or controlling the object at a distance can also be suitable). The released state roughly corresponds to the user not holding the object. A simple example of the two states can include the holding, then throwing of a ball. While in the holding state, the method provides force feedback to the user representation of forces that the user might experience if the user were holding an actual object. The forces are not applied when in the released state.

A method for generating a continuous mathematical model of a feature common to subjects in a subject group includes selecting a sample data set from each subject in the subject group, selecting a set of expansion functions to be used in the representation of the sample data set, mathematically expanding each member of the sample data set in the form of a summation of results of multiplying each the expansion function in the set of expansion functions by a different mathematical parameter wherein the expanding determines a value for each of the different mathematical parameters, deriving a corresponding distribution function for each of the mathematical parameters, and generating the continuous mathematical model of the feature from the derived distribution functions and the expansion functions. In this way, the model is continuous in time, incorporates dependencies between various parameters, and allows for creation of simulated subjects having pertinent features occurring in real subjects.

A method and apparatus for providing force feedback to a user operating a human/computer interface device and interacting with a computer-generated simulation. In one aspect, a computer-implemented method simulates the interaction of simulated objects displayed to a user who controls one of the simulated objects manipulating a physical object of an interface device.

A linked volumetric representation for graphical objects is presented together with techniques for physically-plausible modeling of object cutting, joining and tearing. In one embodiment, each element is may be explicitly linked to its six nearest neighbors by storing pointers to those neighbors in the element's data structure. The link between two elements can be cut when a graphical representation of cutting tool passes between the elements by setting the appropriate neighbor pointers in the two elements to point to NULL instead of to each other. If material limits in the link between two elements are exceeded during simulation of object deformation, the link can be torn apart by setting the appropriate neighbor pointers in the two elements to NULL. When a joining tool is applied to two volumetric objects in close proximity, edge elements in the two objects that have complimentary neighbors set to NULL can be joined by setting these missing neighbors to point to each other.

A method for simulating objects includes receiving a target shape associated with a simulated object. A difference is determined between the target shape and a measured shape associated with the simulated object. One or more forces are generated to act on the simulated object to reduce the difference between the target shape and the measured shape. The target shape may be updated when the difference between the target shape and the measured shape exceeds a predetermined tolerance. Updating the target shape may include reducing the target shape to move the target shape closer to the measured shape.

Contact of rigid bodies is simulated with friction. A contact point is determined as a mid point between closest points on each body. An integrated relative velocity (IRV) vector is computed, and is minimized by applying forces to both bodies. If the IRV value exceeds a threshold the bodies are deemed to be sliding. Non-penetration constraint and friction values are determined in separate processes and the output of one is fed to the other.
