Abstract: A recording method and device uses a low-power-consumption recording system; an operation mode of the low-power-consumption recording system is configured, where the operation mode includes a first-stage operation mode, a second-stage operation mode, and a third-stage operation mode; switching is performed to a current operation mode based on a trigger condition of each operation mode; and power-on/off processing logic of each unit in the low-power-consumption recording system is scheduled based on the current operation mode, to perform video recording. Therefore, energy consumption is optimized, a continuous video monitoring capability is maintained, and a missed recording problem is resolved when a camera with a battery triggers and starts video recording through heat source sensing.

Abstract: This application relates to techniques for improving sensor cleaning techniques. The techniques described herein utilize heat generated by multiple heat generating components of a vehicle, which is normally wasted. The techniques collect the waste heat to heat fluid stored in a reservoir. The heated fluid is further dispensed to heat and/or clean sensors. In some examples, a vehicle implementing the techniques includes a computing system to control an operation of the vehicle; a sensor to sense an environment of the vehicle; and a sensor cleaning system to clean the sensor with a fluid. In implementations, the sensor cleaning system includes a heat exchanger to apply heat generated by a heat generating component to heat fluid in a reservoir to generate heated fluid, and a dispenser fluidly coupled to the reservoir and configured to dispense the heated fluid toward the sensor to heat or clean the sensor.

Abstract: A wireless audio monitoring method and a wireless audio system. The wireless audio monitoring method includes: establishing a first communication link between a primary audio device and a sound source device, so that the primary audio device acquires characteristic parameters of the sound source device; using, by the primary audio device, the characteristic parameters of the sound source device to masquerade as the sound source device and become a pseudo sound source device; establishing a second communication link between the pseudo sound source device and a secondary audio device, so that the secondary audio device acquires communication parameters of the first communication link; and monitoring, by the secondary audio device, the first communication link according to the communication parameters of the first communication link. The secondary audio device can acquire part of information in the communication parameters of the first communication link when the second communication link is established.

Abstract: A method, a device and a non-transitory computer-readable storage medium for scheduling resources for multicast services, the method comprising: performing packet detection for data of a multicast service received from a network-side device. If the data has a relatively stable packet size at the time of detection and is characterized by periodicity, the multicast scheduling mode is initiated for the user equipment where the multicast group corresponding to the multicast service is located.

Abstract: A vehicle may comprise an actuator system. The actuator system may comprise an indicia portion (e.g., a retroreflector, etc.), a masking element that exposes the indicia portion in a first state and covers the indicia portion in a second state, and a linkage coupling the masking element to an actuator. In the case of a bidirectional vehicle, operation of the actuator may be based at least in part on a determination of the vehicle changing a direction of travel. The actuator system may cause a first set of one or more actuator systems disposed on a first end of the vehicle to transition from a first state to a second state and/or cause a second set of one or more actuator systems disposed on a second end opposite the first end of the vehicle to transition from the second state to the first state.

Abstract: Techniques for managing the doors of a vehicle are discussed herein. In some examples, a vehicle may have one or more doors configured to open and close. The doors may include one or more sensor devices located along the inside edges of the doors. The sensor devices may be configured to capture sensor data of a region between the doors.
