Abstract: Devices and methods for connected isochronous stream (CIS) swapping are disclosed. In an example Bluetooth™ setting, a smartphone can be connected to multiple earbuds. It is possible that both earbuds include microphones, but only one microphone is enabled at a given time. That is, only one of the CISes established between the smartphone and the earbuds is bidirectional, and the other is unidirectional. The disclosed techniques enable the CISes to be swapped between the earbuds so that the earbud with better microphone quality will have ownership of the bidirectional CIS.

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: Systems and methods are directed to discovering trusted remote devices and establishing trusted communications with trusted remote devices. A local device can determine one or more time periods of expected silence in a communication between the local device and a remote device; and embed trusted communication messages in the one or more time periods for at least one of: discovering that the remote device is a trusted remote device, performing a trusted communication with the trusted remote device. The communication may be based on a Bluetooth protocol in a link layer.

Abstract: A device includes a memory configured to store instructions and one or more processors configured to execute the instructions. The one or more processors are configured to execute the instructions to obtain link data corresponding to a communication link to a second device. The one or more processors are configured to execute the instructions to select, at least partially based on the link data, between an ambisonics mode and a stereo mode.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include determining that a quality condition of a primary Bluetooth-enabled device is lower than a quality condition of a secondary Bluetooth-enabled device. The primary Bluetooth-enabled device may transmit, to the secondary Bluetooth-enabled device, a handover request message based on the determining. The handover request message may include a subset of connection information associated with a connection between the primary Bluetooth-enabled device and a device in wireless communications with the primary Bluetooth-enabled device. The primary Bluetooth-enabled device may receive, from the secondary Bluetooth-enabled device, a handover response message based on the handover request message. As a result, the primary Bluetooth-enabled device may handover, to the secondary Bluetooth-enabled device, at least one logical transport channel of the set of logical transport channels based on the handover response message.

Abstract: Methods, systems, and devices for ventilating are described. Generally, the described methods, systems, and devices may support generating subsonic air pressure waves for enhancing air ventilation, heating, and cooling applications. Specifically, a transducer device may be configured to provide air ventilation, heating, and cooling based on a generated waveform. For example, the transducer device may be coupled to a waveform generator that may generate a repeating asymmetric waveform having an attack and decay profile for generating pulses (e.g., pressure waves) that propagate outward. In some implementations, multiple transducer devices may be configured to operate synchronously with each other to further enhance the air ventilation, heating, and cooling application.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for authenticating data transmissions using backchannel techniques. Some implementations more specifically relate to authenticating broadcast isochronous communications between unconnected wireless communication devices using backchannel challenge and response exchanges. Some implementations involve the generation and verification of a secret code based on an authentication token and a shared secret key. The authentication token and secret code may be exchanged via a backchannel between unconnected broadcasting and receiving devices to authenticate a broadcast isochronous stream.

Abstract: The disclosure relates to a magnetic communication method that does not use induction. For example, a transmitter device may generate a magnetic field in a controlled direction and rotate the magnetic field around one or more axes. As such, an angle according to which the magnetic field is rotated at the transmitter device may be used as a variable upon which to encode data transmitted to a receiver device that can sense a direction of the magnetic field along two or more axes. Furthermore, to achieve higher data rates, multiple rotation angles could be used to encode the data transmitted from the transmitter device to the receiver device, which may further improve security because reading and/or generating the modulated magnetic field may be increasingly difficult from any significant distance away from the transmitter device and the receiver device.

Abstract: This disclosure describes a first slave device that transmits information to a second slave device indicating that a first data packet was improperly received from a master device, so that a corresponding data packet may be relayed from the second slave device to the first slave device. In an aspect, the second slave device may receive a first data packet followed by an indication that the first slave device improperly received the first data packet, where the second slave device is configured to relay the first data packet to the first slave device in response thereto. In another aspect, the second slave device may receive a request to listen for a separate data stream of the first slave device based on a first data packet being improperly received by the first slave device and transmit a second data packet of the separate data stream to the first slave device.
