Abstract: The subject matter includes a smart device control method, comprising: receiving a device control instruction, and acquiring device distance information respectively between the first positioning device and each smart device, and between the second positioning device and each smart device: calculating a LOS deviation angle between a wearer of the head-mounted device and each of the smart devices based on the device distance information, wherein the LOS deviation angle is an angle between the wearer's direct LOS and a relative direction of the device, and the relative direction of the device is a direction of a line connecting a midpoint of a connection between the first positioning device and the second positioning device to the smart devices: and determining a smart device with a LOS deviation angle less than a pre-set value as a to-be-controlled device, and sending a device control instruction to the to-be-controlled device.

Abstract: Provided are a bone conduction-based eating monitoring method and apparatus, a terminal device, and a storage medium, the method including monitoring, by means of smart glasses, a chewing behavior for food being eaten to obtain a vibration signal of skull related to the chewing behavior; counting the number of chews according to the vibration signal to obtain the number of consecutive chews; and if the number of consecutive chews does not reach a target number of chews and the chewing behavior of a user terminates, sending first prompt information; if the number of consecutive chews reaches the target number of chews, sending second prompt information.

Abstract: Disclosed in a charging box including a lower housing and an upper housing slidably connected to a top opening of the lower housing, wherein the lower housing is provided with a lower inner housing therein, a top of the lower inner housing is opened and provided with an earphone slot, the lower inner housing is rotatably connected to the lower housing, and the upper housing is connected to the lower inner housing by a transmission structure, wherein during an opening movement of the upper housing, the transmission structure is configured to drive the lower inner housing to rotate, such that at least a part structure of the lower inner housing protrudes upward out of the top opening.

Abstract: A method, an apparatus, and a communication node for suppressing output noises of peripheral component interconnect express (PCIe) devices in optical fiber communication is provided. The communication node includes a PCIe chip and a detection and control circuit connected to a transmitting end of the PCIe chip. The PCIe chip transmits an electrical signal by a transmitter of a first lane. The detection and control circuit detects a differential-mode voltage of the electrical signal. If the differential-mode voltage is lower than a first threshold, the detection and control circuit controls an optical module connected to the PCIe chip not to transmit an optical signal through the first lane of the optical module. When a PCIe system includes the communication node, output noises of the transmitter is suppressed, and a normal optical fiber communication link is ensured.

Abstract: Embodiments of the present invention relate to a peripheral component interconnect express endpoint device accessing method, a computer system, and an apparatus. A state of an access request sent by a processor is monitored, and a simulation response message for the access request is sent to the processor when it is determined that the PCIe endpoint device sends no response message for the access request. Therefore, according to the simulation response message, the processor can confirm completion of the procedure corresponding to the previously sent access request, and shut down a timer for timing the access request and clear the buffered access request, thereby keeping normal processing in the processor and avoiding the MCE resetting problem that arises from accumulation of access requests in the processor.
