Abstract: Access terminals are adapted to communicate with registration servers to enable a registration server to perform timer-based registrations on behalf of an access terminal. The access terminal can cease performing such timer-based registrations as long as the registration server performs the registrations, and may power down until event data is available for transmission or reception. When a registration server performs timer-based registrations on behalf of an access terminal, the registration server can periodically communicate with a network entity to conduct the timer-based registrations for the access terminal. The network entity can receive a timer-based registration message from a registrations server for registering an access terminal. In response to such a message, the network entity can register the access terminal. Sensors and controllers may be used with some embodiments to collect and analyze data and for potentially taking action.

Abstract: Multi-step programming of heat-sensitive non-volatile memory (NVM) in processor-based systems, and related methods and systems are disclosed. To avoid relying on programmed instructions stored in heat-sensitive NVM during fabrication, wherein the programmed instructions can become corrupted during thermal packaging processes, the NVM is programmed in a multi-step programming process. In a first programming step, a boot loader comprising programming instructions is loaded into the NVM. The boot loader may be loaded into the NVM after the thermal processes during packaging are completed to avoid risking data corruption in the boot loader. Thereafter, the programmed image can be loaded quickly into a NV program memory over the peripheral interface using the boot loader to save programming time and associated costs, as opposed to loading the programmed image using lower transfer rate programming techniques. The processor can execute the program instructions to carry out tasks in the processor-based system.
