Abstract: A softAP bridge is created to support a mesh network that also works seamlessly with any home Wi-Fi AP routers by using Layer-3 techniques to simulate a Layer-2 bridge. With this softAP bridge, Wi-Fi chipsets with integrated special Wi-Fi MAC Layer-2 mesh network support (e.g., 802.11s), or external gateway hubs, are not required. To accomplish this solution, one of the wireless capable devices may be designated as a relay device for communicating data packets between a home AP router and the remaining wireless capable devices that are designated as client devices.

Abstract: A lockable torque wrench providing acoustic indication includes a main shaft, a handle tube, a first cleat, a locking ring, a second cleat, a clip, and a torque-adjusting component. The handle tube is mounted around the main shaft, and the locking ring is rotatably mounted around the handle tube. The first cleat is movably provided between the locking ring and the handle tube. The second cleat is movably provided between the main shaft and the locking ring. The torque-adjusting component is located between the main shaft and the handle tube. Thereby, a user can rotate the locking ring to lock or release the main shaft and the handle tube with respect to each other. When the two are released for torque adjustment of the torque wrench, the second cleat pushes the clip to impact the locking ring, thereby generating acoustic indication for the current torque level.

Abstract: A lockable torque wrench with adjustment indication includes a rod body, a handle, a plurality of rollers having a rolling pillar, a rotation ring, and a pressing member. The rod body is combined into the handle and rotatable to protrude or retract against the handle for adjusting the torque. The rotation ring is disposed on an extension tube of the handle and mounted around the rollers. The rotation ring is switched between a locked and a relax positions. The pressing member has combination portions at two sides of the extension tube, and permanently engages the rolling pillar. In an ascend position, the rolling pillar is pressed toward the rod body by the prestress force supporting the pressing member. When meeting a position limiting groove, the rolling pillar is pressed to lower in the position limiting groove, providing a switch sensation formed for the user.

Abstract: Described are techniques for distributing audio data to multiple audio devices for generation of a synchronized audio output. A master device may receive audio data from a content server or other remote data source and store the audio data in a local cache. The master device may provide the audio data to multiple slave devices using a single multicast transmission. In some cases, the master device may also provide the audio data to individual slave devices unable to receive the multicast transmission using a network connection. Each slave device may store the audio data in a local cache. To generate the audio output, each audio device may retrieve the audio data from the associated local cache, which may enable the audio data to be distributed without modifying the commands used by audio applications to generate the audio output.

Abstract: A method of animating a display to reflect mood is applied in a human-computer interaction device. The method acquires voice of user, recognizes the voice content and analyzes context of the voice. The context comprises user semantic and user emotion feature. The method further compares the context with a first relationship table, which defines a relationship between a number of preset contexts and a number of preset animated images. The method further determines a target image from the first relationship table when the context is matched therein, and displays the animation of the target image on a display unit of the human-computer interaction device.

Abstract: Described are techniques for modifying the data rate used to transmit audio data from a master device to slave devices. After receiving a signal, each slave device requests transmission of one or more packets and reports an individual error rate. A cumulative error rate may also be determined based on the individual error rates and the retransmission requests. If any individual error rate or the cumulative error rate exceeds a maximum threshold, the data rate used to transmit the audio data is decreased. If an individual error rate is less than a minimum threshold, the data rate may be increased. If an error rate exceeds a critical threshold, the data rate may be reduced to a minimum value supported by the devices.

Abstract: Described are techniques for configuring a selected audio device of a group of audio devices to send audio data to multiple other devices to enable the devices to provide a synchronized audio output. Link quality values indicative of the quality of communication links between audio devices and an access point and between different audio devices may be used to form subsets of devices in which a first master device receives audio data from a data source, provides data to other master devices via the access point. A value indicative of the airtime that would be used to communicate data to other audio devices may be determined for at least a portion of the audio devices. Additional subsets of audio devices may be formed if the airtime for the existing subset does not exceed a maximum quantity of airtime.

If the airtime value is less than a threshold airtime value, the audio data may be provided to the audio devices. If the airtime value exceeds the threshold airtime value, a notification may be generated indicating the relationship between the airtime value and the threshold airtime value.

Abstract: Described are techniques for configuring a group of devices to distribute and receive data in a manner that reduces consumption of network resources. A larger group of devices may be divided into subsets of devices, each subset including a master device that provides data to multiple slave devices via a multicast transmission. A master device may be determined based on the respective signal quality between the audio devices and an access point, and the number of other audio devices to which each respective audio device may provide data. Other devices having respective signal quality for communication with the master device that exceeds a threshold may be designated as slave devices. Once a first subset is formed, the remaining devices may be grouped into additional subsets. Remaining devices that are not a part of any subset may receive data via communication with an access point.
