Abstract: A method for tracking three-dimensional movement of an object and focusing thereon is provided. Software repeatedly detects three-dimensional locations of one or more objects and image quality by sampling images at many parameter settings as the objects move in three-dimensional environment. The images are ranked occurring to a fitness score and parameter settings for subsequent images to established using a biologically-inspired algorithm.

Abstract: A method and apparatus are disclosed that provide a technique for testing a data-processing system that enables communications between two or more telecommunications endpoints. An example of such a data-processing system is a Session-Initiation Protocol (SIP) proxy server. In particular, a test-execution system, in accordance with the illustrative embodiment of the present invention, transmits test-related signals to and receives test-related signals from one or more endpoints, such as SIP-enabled telephones. Some of the transmitted test-related signals direct an endpoint to transmit a message, such as a session-initiation request, to the data-processing system under test. Some of the received test-related signals comprise information from an endpoint, such as whether or not a message has been received from the data-processing system under test.

Abstract: Optimized synchronization planning and clock distribution for a network of interconnected digital equipment is achieved by designating a network node at the highest stratum level as the master clock node, forming a group of all unassigned nodes connected to the assigned node or nodes, selecting subgroup of all nodes from the group wherein the subgroup includes all nodes having the highest stratum level of the group, limiting the subgroup to the nodes which have a desired characteristic when such nodes are included in the subgroup, determining the synchronization performance of each node in the subgroup according to a predetermined criterion, assigning one node from the subgroup as a clock timing receiver wherein the one node exhibits the best performance for nodes in the subgroup, and iterating the method at the forming step.

Abstract: Faster, yet, completely efficient and exhaustive testing is afforded an entity (e.g., protocol, VLSI circuit, software application) represented as finite state machines by employing the present method in which test sequences are generated according to minimum cost function rules. Minimum cost unique signatures are developed for state identification of the finite state machine. Based upon the minimum cost unique signatures, a minimum cost test sequence is generated to cover every state transition of the finite state machine. As a result, every testable aspect of the entity is guaranteed to be tested using a minimum number of steps which represents a considerable cost savings.
