Abstract: A simulation of an autonomous driving vehicle (ADV) includes capturing first data that includes a control command output by an autonomous vehicle controller of the ADV, and capturing second data that includes the control command being implemented at a control unit of the ADV. The control command, for example, a steering command, a braking command, or a throttle command, is implemented by the ADV to affect movement of the ADV. A latency model is determined based on comparing the first data with the second data, where the latency model defines time delay and/or amplitude difference between the first data and the second data. The latency model is applied in a virtual driving environment.

Abstract: There is provided a Bluetooth audio system including a gateway, a primary device and at least one slave device. The gateway and the primary device communicate Bluetooth packets therebetween based on the standard Bluetooth communication protocol. The at least one slave device accomplishes synchronization with the primary device using a user-defined Bluetooth communication protocol so as to listen or snoop the Bluetooth packets exchanged between the gateway and the primary device.

Abstract: Distributed failover of a failed BE, and failback of the failed BE when it recovers, are described. A separate pool of memory may be reserved for each BE on a storage system. Each such pool may be further divided into sub-pools. When a BE fails, the one or more other active BEs on the storage system may be notified, and each such active BE may attempt to take ownership of one or more sub-pools of the BE and execute the one or more pending write operations of the failed BE. Upon completing execution of the pending write operations in a failed-over sub-pool, the ownership of the sub-pool may be returned to the failed BE. When the failed BE recovers, the recovered BE may attempt to take back control of one or more of its sub-pools.

Abstract: In one embodiment, simulation of an autonomous driving vehicle (ADV) includes capturing first data that includes a control command output by an autonomous vehicle controller of the ADV, and capturing second data that includes the control command being implemented at a control unit of the ADV.

Abstract: A method is provided that includes: acquiring environmental data of a current environment in which a vehicle is located; determining, according to the environmental data, that the current environment meets an environment collection requirement; in response to the determining, controlling one or more collection devices of the vehicle to perform data collection according to a current production flow of the vehicle, the one or more collection devices correspond to the current production flow; and controlling the data collection of the one or more collection devices based on a data collection situation of the one or more collection devices.

Abstract: A method applied into a controller of a wireless Bluetooth device includes: providing a first flag and a second flag; asserting the first flag when the controller successfully receives the particular packet transmitted from the audio gateway; asserting the second flag when the controller successfully receives an acknowledgement from a secondary device wherein a reception of the acknowledgement indicates that the secondary device successfully receives the particular packet; and transmitting an acknowledgement of a particular packet to an audio gateway when the first flag and the second flag are asserted.

Abstract: A non-transitory computer readable medium storing at least one program, wherein a wireless communication method is performed while the program is executed. The wireless communication method comprises: (a) receiving a plurality of data groups, wherein the data groups do not pass an error checking procedure; (b) selecting a portion of at least one of the data groups; and (c) reconstructing a reconstruction data group based on the portions selected in the step (b).

Abstract: There is provided a fast paging procedure in which a master device repeatedly sends the paging message to a slave device using predetermined channel frequencies, wherein a selection of the predetermined channel frequencies is not calculated or predicted from the slave's Bluetooth device address. When the master device receives a slave page response message at one frequency among the predetermined channel frequencies, the master device transmits an FHS packet to the slave device at the same frequency in which the slave page response message was received.
