Abstract: Techniques described herein provide for the detection and capture of neural signals in a manner that compresses data sent from electrodes to controller by several orders of magnitude over current techniques. In particular, embodiments include detecting a threshold amplitude and/or slope of a detected neural signal, and capturing the detected neural signal once these thresholds are met. A threshold timing detector may be implemented as well. Additionally, these thresholds may be configurable to accommodate various factors, such as electrode placement, sensitivity, etc.

Abstract: Methods, systems, and devices for data rate adaptation to extend the range of wake-up radio transmissions sent to a wake-up radio of a station (STA). Data rate adaptation procedures may be used to select a data rate for wake-up radio transmission based on one or more identified parameters. An access point may execute one or more different types of rate adaptation procedures to select the appropriate data rate. In some examples, the access point may select a data rate of wake-up radio transmissions based on one or more messages failing to be successfully decoded. In some examples, the access point may select a data rate of wake-up radio transmissions based on a distance between the access point and the station. In some examples, the access point may select a data rate of wake-up radio transmission based on information identified during a training procedure.

Abstract: Systems and methods are disclosed for enhancing the power efficiency of low power internet of everything (IOE) devices or user equipments (UEs). A UE or IOE having a low power companion receiver maintains its full power receiver in a sleep state until it receives a wake up indicator from a base station. In response to the wake up signal, the UE or IOE powers up its full power receiver and receives data from the base station. The base station further schedules the wake up signals so as not to collide with control signals expected by UEs or IOEs without low power receivers, or those UEs and IOEs are configured to detect and react to the wake up signals.

Abstract: Techniques provided herein are directed toward providing a robust pulse width modulated (PWM) amplitude modulation scheme that enables medical implants with highly inaccurate LOs to reliably receive downlink communications from an interrogator device by using pulse width to encode data. Synchronization and data fields can comprise pulse pairs, distinguishable by medical implants from a ratio of the duration of a long pulse to the duration of a short pulse within the pulse pair. Thus, synchronization can be easily and robustly obtained

Abstract: 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.

Abstract: In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.

Abstract: A spatio-temporal random voting scheme is provided that incorporates location distribution, spatial randomness, and temporal randomness in the collection of information from a plurality of sensing devices within the cognitive network. The region is divided into a plurality of sectors, where each sector is a portion of the region. A subset of sectors is selected from the plurality of sectors in the region to provide spatial randomness. A device is randomly selected from each sector in the subset of sectors to provide additional spatial randomness to the information collection process. Temporal randomness may be introduced by randomly selecting a timeslot within a sensing window period in which devices are to scan a frequency spectrum band to determine if a signal energy above a threshold is detected. Sensing reports are then collected from the selected sensing devices and used to determine whether the frequency spectrum band is available or in use.
