Abstract: A method and system for assisting a user in maintaining a predetermined pace along a track with a specific predetermined end goal. The preferred embodiment uses a PDA or similar device to allow a user set a specific course goal and to enter (or download) a previous profile pace target along with checkpoint data for a specified track, detecting start/stop and checkpoints along a course, normalizing the user time at each checkpoint and providing wireless speech ‘behind/ahead’ feedback (either time or energy) to a user at each checkpoint along a specified track. The present invention may provide the user with a variable pace along a track or course utilizing upcoming terrain, percentage of work completed and/or user power profiles and may normalize a user goal to other competitors having faster or slower track times.

Abstract: A data manager manages global data within a Java Virtual Machine (JVM) installed and running in an embedded device. The data manager maintains a data class list that stores data class identifiers associated with each data class object currently loaded and cached in a data cache in the embedded device. The data manager specifies a universal data manager API, which includes a data class loader method, a data object creation method, get and put data methods which allow manipulation of existing data objects, and an unload method which unloads cached data objects from the embedded device. The data manager comprises or is responsive to a memory management handler which detects low- or out-of-memory conditions and which selects one or more data class objects to be unloaded from the data cache.
