Abstract: A graphical user interface configured to facilitate replay debugging in distributed software programs is provided. In one or more examples, the graphical user interface provides a visual progress bar, wherein a position on the visual progress bar corresponds to a log file generated when the distributed software program is executed. The user can manipulate the graphical user to replay the log files and visualize the state of the playback through the visual progress bar. The graphical user interface can also allow the user to provide watch points and can allow the user to visualize variables that are contained within the log files. The watch points can represent one or more conditions. The log files can be analyzed to determine if they meet the condition specified in the watch point, and if the log files meet the condition, a visual indication can be provided on the visual progress bar.

Abstract: A control device and method controls an animal's location. A GPS receiver and a processor determine the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal. If the position of the animal relative to the target is less than a predetermined distance and the animal's velocity relative to the target is within a predetermined range and the heading direction of the animal is within a predetermined orientation relative to the target, then a non-aversive stimulus is applied to the animal, and removal of a non-aversive stimulus is selectively effected when the animal's velocity relative to the target is outside of the predetermined range, or the heading direction of the animal changes by more than a predetermined amount, otherwise the non-aversive stimulus is first removed followed by application of an aversive stimulus to the animal.

Abstract: A control device and method is taught for controlling an animal's location. A GPS receiver receives GPS signals and a processor determines the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal in response to received signals.

Abstract: Virtual fencing of an animal includes a microprocessor for continuously determining the position of an animal relative to a target and whether the animal is moving relative to the target. A stimulus unit applies a sensory stimulus to the animal in response to signals received from the microprocessor. The microprocessor is programmable such that if the distance between the animal and the target is less than a predetermined distance and if the animal is moving in a direction towards the target a stimulus is applied to the animal and the stimulus is withdrawn when the animal either stops, retreats from the target, or accelerates while the distance between the animal and the target is less than the predetermined distance.

Abstract: An apparatus for the virtual fencing of an animal is provided which includes a microprocessor for continuously determining the position of an animal relative to a target and to determine whether the animal is moving relative to the target. The apparatus further includes a stimulus unit for applying a sensory stimulus to the animal in response to signals received from the microprocessor. The microprocessor is programmable such that if the distance between the animal and the target is less than a predetermined distance and if the animal is moving in a direction towards the target a stimulus is applied to the animal and the stimulus is withdrawn when the animal either stops, retreats from the target, or accelerates whilst the distance between the animal and the target is less than the predetermined distance. In addition a method for the virtual fencing of an animal is provided.
