Systems and methods of pre-allocating identifiers to wireless devices for use in requesting resources over a random access channel are described. A wireless communication system includes a random access channel over which wireless devices can anonymously send requests for resources. The base stations receiving and processing the anonymous requests reduces the probability of random access channel collisions and conserves the resources needed to support the anonymous requests by pre-allocating one or more identifiers to select wireless devices. The wireless devices having the pre-allocated codes can transmit a particular code over the random access channel as a request for resources that uniquely identifies the requester.

Pre-allocated random access identifiers

Aspects of the present disclosure relate to protecting the contents of memory in an electronic device, and in particular to systems and methods for transferring data between memories of an electronic device in the presence of strong magnetic fields. In one embodiment, a method of protecting data in a memory in an electronic device includes storing data in a first memory in the electronic device; determining, via a magnetic sensor, a strength of an ambient magnetic field; comparing the strength of the ambient magnetic field to a threshold; transferring the data in the first memory to a second memory in the electronic device upon determining that the strength of the ambient magnetic field exceeds the threshold; and transferring the data from the second memory to the first memory upon determining that the strength of the ambient magnetic field no longer exceeds the threshold.

Dynamic memory protection

Various embodiments provide systems and methods among wireless earpieces in a wireless communication network that enable balancing the batteries in the wireless earpieces to be depleted at approximately the same rate. Various embodiments intelligently and dynamically swap master/slave roles among two or more Bluetooth&#xae; wireless earpieces coupled to a data source device to optimize battery life in both wireless earpieces. The various embodiments provide methods and systems for swapping master-slave roles so that there is less impact on the user experience.

Smart battery wear leveling for audio devices

A system for receiving multiple conversations or messages and for playing the multiple conversations or messages with a mobile device and wireless earpieces. The system may determine various presentation parameters based on various characteristics of the received messages and may play the messages such that audio appears at distinguishing locations around the user. The system may change how messages and/or conversations are played in response to recognize a change in the focus of the user based on detected user inputs, such as body movement gestures.

Audio systems and methods

The disclosure generally relates to a memory power reduction scheme that can flexibly transition memory blocks among different power states to reduce power consumption (especially with respect to leakage power) in a manner that balances tradeoffs between reduced power consumption and performance impacts. For example, according to various aspects, individual memory blocks may be associated with an access-dependent age, whereby memory blocks that are not accessed may be periodically aged. As such, in response to the age associated with a memory block crossing an appropriate threshold, the memory block may be transitioned to a power state that generally consumes less leakage power and has a larger performance penalty. Furthermore, one or more performance-related criteria may be defined with certain memory blocks to prevent and/or automatically trigger a transition to another power state.

Ultra-low-power design memory power reduction scheme

A power management system for stack memory thread tasks according to some examples of the disclosure may include a non-collapsible memory region, a collapsible memory region configured below the non-collapsible memory region, a memory management unit in communication with the non-collapsible memory region and the collapsible memory region, the memory management unit operable to allocate a portion of the non-collapsible memory region and a portion of the collapsible memory region to a thread task upon initialization of the thread task and power down the portion of the collapsible memory region allocated to the thread task upon receiving a power down command.

Systems and methods for implementing power collapse in a memory

Various embodiments may provide systems and methods among wireless nodes in a wireless communication network that enable balancing the batteries in the wireless nodes to be depleted at approximately the same rate. Various embodiments intelligently and dynamically swap master/slave roles among wireless nodes (e.g., wireless earpieces) coupled to a wireless source device to optimize battery life in both wireless nodes. The various embodiments may provide methods and systems for swapping master-slave roles so that there is reduced impact on the user experience.

Techniques provided herein are directed toward providing a selection protocol that can be used in such biological measurement and stimulation systems to select only a portion of the medical implants for reporting during a particular system cycle. In particular, the interrogator device can send the first message that defines a group to the medical implants, then send a second message with the identifier of the group to trigger communications with the medical implants of that group.

Medical implant selection protocol

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.

Multi-step programming of heat-sensitive non-volatile memory (NVM) in processor-based systems

The various aspects provide for wirelessly connecting mobile devices and wearable devices, which may enhance battery life and user experience. The embodiments may include a wearable device that may receive from a mobile device a request to wirelessly connect to the wearable device. The wearable device may establish with the mobile device a first wireless connection. The wearable device may recognize termination of the first wireless connection by the mobile device and send to the mobile device a second request to establish a second wireless connection. The wearable device may establish the second wireless connection between the mobile device and the wearable device.
