Abstract: This disclosure provides systems, methods and apparatus for clear channel assessment (CCA) enabled narrowband (NB) communications. In some implementations, a device is configured to associate with an NB channel (such as a Bluetooth channel), perform a CCA to assess whether the NB channel is clear, and transmit on the NB channel when clear. If the NB channel is not clear, the device may prevent transmitting on the NB channel. The device may prevent avoiding the NB channel after the first time that the NB channel is not clear. If the NB channel remains not clear (such as over a number of CCAs for the NB channel), the device may avoid the NB channel by removing the NB channel for FH for an amount of time. In some implementations, the device may be configured to perform frame based equipment (FBE) CCAs for one or more NB channels.

Abstract: Motion-detection systems are often used to detect presence of humans. Such motion-detection systems are often based on passive infrared (PIR) sensors. Unfortunately, such detection systems are unable to reliably distinguish between humans and other entities such as animals and moving heat sources. To address this issue, it is proposed to detect a presence of real time clock (RTC) devices in addition to detecting the heat sources to better determine whether a detected entity is a human.

Abstract: Methods, systems, and devices for wireless communications are described. A device may break down (e.g., filter) a frequency band of an input signal into various subbands, and an encoding stage may then allocate bits across the various subbands. In some examples, the encoding stage may allocate proportionally more bits to higher prioritized (e.g., lower frequency) subbands. Once the subbands have been encoded, the output of each individual encoder (e.g., each encoded subband) may be transmitted in a packet. As such, subbands transmitted as single packets (e.g., subbands transmitted in individual packets) may be shorter in length and may be more efficiently prioritized by a transmitter and a receiver. For example, subbands may be prioritized based on a location where the most data is found in audio, based on the tone of a speaker (e.g., for speech encoding), etc.

Abstract: Systems and methods for monitoring eye movement of a viewer may enable monitoring of a viewer's focus to enhance attention based media control. One example includes providing visual stimuli on a screen, monitoring a viewing focus of a viewer to determine if the viewing focus of the viewer is on the visual stimuli and may include stopping the visual stimuli when the viewing focus is determined to be other than on the visual stimuli. The method may also include resuming the visual stimuli when the viewing focus is determined to be on the visual stimuli.
