Abstract: A portable thread environment comprising: an application programming interface configured to support multiple application program tasks, wherein each task is either a preemptive task comprised of preemptive threads or a cooperative task comprised of cooperative threads; host adaptation logic for communicatively interfacing said cooperative tasks, preemptive tasks, cooperative threads and preemptive threads with a host processing environment; a scheduler configured to determine an execution order of cooperative threads and preemptive threads based on each cooperative thread's and preemptive thread's priority levels.

Abstract: A method is described comprising: receiving a synchronization packet transmitted form a first device; receiving a data packet transmitted from the first device, the data packet being offset from the synchronization packet by a particular amount of time; and identifying the first device based on the amount of time from which the data packet is offset from the synchronization packet. Also disclosed is a method implemented on a first wireless device comprising: transmitting a synchronization packet to a second wireless device; and transmitting a first data packet to the second wireless device, the first data packet being offset from the synchronization packet by a first amount of time, wherein the first amount of time from which the first data packet is offset from the synchronization packet identifies first wireless device to second wireless device.

Abstract: Distributed applications in a portable thread environment are disclosed. In one embodiment, a method comprises receiving a message from a first PTE at a second PTE, wherein the message contains a destination address; determining if the message is intended for the second PTE using the PTE destination address; routing the message to a third PTE if the message is not intended for the second PTE; and executing threads associated with the message in the second PTE if the message is intended for the second PTE.

Abstract: A portable thread environment comprising: an application programming interface configured to support multiple application program tasks with each task comprised of one or more threads; host adaptation logic for communicatively interfacing the tasks and threads with a host processing environment; and a scheduler configured to determine an execution order of the one or more threads based on one or more execution variables.

Abstract: A diagnostic tool for a portable thread environment is disclosed. In one embodiment, a system comprises a first portable thread environment (PTE), comprising a diagnostic tool; a second PTE configured to receive and send threads; a third PTE configured to receive and send the threads; and a PTE router configured to receive the threads and route said threads, wherein the router copies the threads and routes the copies to the diagnostic tool.

Abstract: A finite state machine in a portable thread environment is disclosed. In one embodiment, a system comprises a finite state machine operating within a portable thread environment; and one or more PTE message generators configured to pass state information contained in PTE messages to the finite state machine, wherein the finite state machine changes states according to the state information.
