Abstract: The disclosure generally relates to connecting wireless devices based on a correlation between different audio sources. For example, according to various aspects, a first wireless device may capture sound via a microphone and receive audio content from a second wireless device via a wireless receiver. Accordingly, a wireless connection may be established between the first and second wireless devices based on a substantial match between the sound captured via the microphone and the audio content received via the wireless receiver. For example, the sound captured via the microphone may be output from a speaker on the second wireless device. In other examples, the received audio content may be sound captured via a local microphone at the second wireless device. In either case, the correlation between the audio received through the microphone and the audio content received over a radio may substantially simplify the procedure(s) used to connect two audio-enabled devices.

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: Methods and apparatuses for establishing a wireless connection are disclosed. In an embodiment, a first communication device transmits a first advertising signal for a first period of time, the first advertising signal configured to advertise that the first communication device is available to establish a first wireless connection, scans for a second advertising signal for a second period of time, the second advertising signal transmitted by a second communication device and configured to advertise that the second communication device is available to establish a second wireless connection, and listens for a third signal for a third period of time, the third signal transmitted by a third communication device in response to the first advertising signal, the third period of time occurring during the second period of time.

Abstract: A method for reducing power consumption is described. The method includes negotiating a receive window of a slave wireless device. The method also includes exchanging timing uncertainty information relating to a clock of the slave wireless device and a clock of the master wireless device. The method further includes transmitting a packet multiple times on a same frequency based on the receive window and the timing uncertainty information.

Abstract: Packets are communicated between a first device and a second device, over a primary data channel, according to an interval. The first device receives over the primary data channel a request from the second device to establish a secondary data channel. The request includes secondary connection parameters including an offset relative to events on the primary data channel, and a sub-interval relative to the interval. Acknowledgement is exchanged and the first and second devices communicate over the secondary data channel according to the secondary connection parameters.

Abstract: A packet is received at a device, over a connection between the device and another device indicating suspending the connection. The device suspends the connection and stores a suspended connection attribute record having connection attributes for resuming the connection. The device receives an advertisement packet having a resume suspended connection request, and determines if the resume suspended connection request is a request to resume the connection associated with the suspended connection attribute record. If determining is affirmative, the device resumes the connection according to the stored connection attributes.

Abstract: In an embodiment, a wireless device for Bluetooth Low Energy technology utilizes interlaced advertising and scanning on a same advertising channel to improve power efficiency. In an embodiment, a device transmits an advertising packet on an advertising channel, waits for an inter frame space, listens for any connection request or scan request during a listening time slot, and upon not receiving a connection request or scan request, begins a scanning window on the same advertising channel to listen to advertising packets. If no advertising packets are received, the advertising channel is incremented and the process of interlaced advertising and scanning begins again.

Abstract: Various aspects directed towards a wearable identity manager system are disclosed. In a first aspect, an association status between a user and a wearable identity manager device is ascertained based on whether the wearable identity manager device is worn by the user, and motion data associated with a movement of the wearable identity manager device is monitored. Authentication data, which includes the motion data, is then transmitted based on the association status. In another aspect, an association status between a user and a wearable identity manager device is again determined based on whether the wearable identity manager device is worn by the user. Here, however, the wearable identity manager device is paired with a pairing device, and authentication data is transmitted to the pairing device based on the association status to facilitate a user authentication via the pairing device.
