Abstract: Two devices (e.g., two wireless Bluetooth earbuds) may exchange device address information (e.g., Bluetooth address information) and may identify a primary address. When either of the devices connect to a source device (e.g., a phone), the primary address may be used by the connecting device such that the pair of devices appear as a single device (e.g., a Bluetooth-pairable device) to the source device, regardless of the device connecting to the source device as the primary device. The primary device may then send identity information (e.g., that has been exchanged with the secondary device) to the source device, such that the source device may connect to either of the two devices. Further, once a primary device connects to the source device, the primary device may transmit, to the secondary device, connection information such that the secondary device may connect to the source device and operate in the primary role.

Abstract: Generally, the described techniques provide for transmission schedule coordination, and in some cases transmission schedule modification, for time division multiple access (TDMA) links amongst devices engaged in communications. A network neighborhood alignment (NNA) protocol may allow devices to inform peer devices of current (e.g., established) connections within the network neighborhood (e.g., of TDMA links established between the device and peer devices, or of TDMA links established between other per devices that are known to the device). Devices may also communicate desired connection preferences, requests for peer device current connection information (e.g., the types of data being transferred by a peer device, the connection type of links associated with the peer device), etc. In some examples, the NNA protocol may establish the information exchange via a dedicated network neighborhood channel (NNC) or via point-to-point messages exchanged between devices (e.g.

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: Methods, systems, and devices for wireless charging are described. A device may be configured to function as a wireless power transmitter or wireless power receiver, or both. In some implementations, the device may be configured with a single coil that may function as a receiver coil and a transmitter coil when desirable. Alternatively, the device may be configured with two separate coils (e.g., a receiver coil to operate as a wireless power receiver and a transmitter coil to operate as a wireless power transmitter).

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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a LMP version request PDU to a second device. The apparatus may receive a LMP version response PDU including at least one of a link layer identification, a version number, or a sub-version number associated with the second device. The apparatus may determine if one or more of the link layer identification, the version number, or the sub-version number included in the LMP version response PDU are associated with a recognized QLM. The apparatus may a first LMP encapsulated header PDU that includes a first QLMP feature request opcode to the second device when it is determined that one or more of the link layer identification, the version number, or the sub-version number included in the LMP version response PDU are associated with the recognized QLM.
