A wearing prompt method for a wearable device and an apparatus, and related to the field of communications technologies, to reduce a probability that the wearable device cannot accurately measure physiological parameters of a user, thereby improving accuracy of measuring the physiological parameters of the user. The method includes: obtaining, by the wearable device, a target PPG (photo plethysmo graph) signal; and prompting, by the wearable device when the target PPG signal is inconsistent with a stored reference wearing parameter, a user to adjust a wearing position of the wearable device and to adjust tightness of wearing the wearable device.

Wearing prompt method for wearable device and apparatus

This application provides a wearable device. The wearable device includes a bearing body and a Bluetooth headset. An accommodating slot is disposed on the bearing body, a first locking component is disposed on the Bluetooth headset, and a second locking component is disposed on the bearing body. The Bluetooth headset is accommodated in the accommodating slot. The first locking component can be locked with the second locking component. The Bluetooth headset includes an operation portion. The operation portion is configured to: unlock the first locking component and the second locking component, and push the unlocked Bluetooth headset out of the accommodating slot. The wearable device in this application can directly accommodate the Bluetooth headset, to provide more convenience to a user.

Wearable device

This application provides a headset accommodating apparatus, a headset, and a portable device. The headset accommodating apparatus includes a base, and an accommodating cavity used to accommodate a headset is formed on the base. The accommodating cavity has a bottom surface, a side wall, and an opening, and has a first end corresponding to a headset head and a second end corresponding to a headset tail. An epitaxial frame that extends toward the second end is formed at an opening of the first end. The apparatus includes a first spring and a sliding block at a side wall of the second end, and the first spring may be compressed in a direction of a connecting line between the first end and the second end. A first end of the sliding block is connected to the first spring, and a protruding part is formed on a second end of the sliding block.

Headset accommodating apparatus, headset, and portable device

A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program.

Terminal management method and apparatus

A power supply terminal, and a charging control method are disclosed. The power supply terminal includes a USB port, a switch, a power source module, and a processor, where the USB port is configured to connect to a power receiving terminal; one end of the power source module is connected to a power source pin VBUS of the USB port and is configured to charge the power receiving terminal by using the power source pin VBUS; a first end of the switch is connected to the data pin D+ and a second end of the switch is connected to the data pin D&#x2212;; when the switch is on and the processor detects that a drop amplitude of the output voltage of the power source module exceeds a preset value, in a process in which the power source module outputs a voltage to charge the power receiving terminal.

Systems and methods for charging via USB port

A terminal management method and an apparatus, where the method includes that a terminal obtains a first light intensity at a first moment and a second light intensity at a second moment according to a first interval period. The second moment is later than the first moment. When a difference between the first light intensity and the second light intensity is greater than a first threshold, and the second light intensity is less than a second threshold, the terminal closes a target program. It can be learnt from above that, the terminal can determine, according to a variation in light intensities, whether the terminal is blocked by clothes, and close the target program. This reduces running power consumption of the terminal and increases a standby time of the terminal.

A mobile power supply terminal and a power supply method is presented. For the mobile power supply terminal, a trigger circuit and a control circuit are added to a conventional device. After a to-be-charged device is connected to the mobile terminal, one end of a power supply interface generates a level signal, to make the trigger circuit generate a trigger signal; and then the control circuit controls, according to the trigger signal, the mobile power supply terminal to enter a power supply mode, and controls a power supply source to charge the to-be-charged device using the power supply interface.

Mobile power supply terminal and power supply method thereof

Embodiments of the present invention disclose a charger integrating a network interface conversion apparatus, which is used with a wireless mobile gateway device. The charger includes a first interface, a power interface, a second interface, a charging circuit, and a network interface adapter circuit. The power interface is connected to an input end of charging circuit. An output end of the charging circuit is connected to the first interface and a power supply terminal of the network interface adapter circuit. The second interface is connected to a signal terminal which has a corresponding format and is of the network interface adapter circuit, and the first interface is connected to a signal terminal which has a corresponding format and is of the network interface adapter circuit.

Charger integrating network interface conversion apparatus

A power supplying method for a wireless network terminal and the wireless network terminal are disclosed. The method includes: detecting potential information of two power lines of a USB (Universal Serial Bus) interface of a wireless network terminal; determining, according to the potential information of the two power lines, a type of a power supply device that is connected to the USB interface; and when the type of the power supply device is a power supply device having a communication capability, controlling the wireless network terminal to work in a predetermined communication mode, so as to implement power supply for the wireless network terminal by using the power supply device. With provided technical solutions, a cost of the wireless network terminal can be reduced, and a battery with a relatively large size is not needed, thereby facilitating miniaturization and integration of the wireless network terminal.
