The preparation method includes preparing a yak hide-derived oligomeric collagen peptide and subjecting the yak hide-derived oligomeric collagen peptide as a protein source to chelation with an iron source in water. A pretreated yak hide is subjected to enzymatic hydrolysis under a pH value of 7 at 50° C. for 4 h with an amount of an enzyme added at 2% to obtain a yak skin-derived collagen with a molecular weight of less than 2 kDa; the chelation is conducted in a peptide-to-iron mass ratio of 1:1 to 5:1 with a peptide concentration of 1% to 5% at 30° C. to 70° C. for 20 min to 60 min under a pH value of 3 to 8; and an iron chelating capacity is 42.72 mg/g under optimal preparation conditions.

Abstract: Provided is a method of preventing false triggering, which is applied to a wearable device, including: if it is detected that a touch structure is triggered, obtaining pressure values acquired by the at least two pressure sensors, wherein the touch structure and the at least two pressure sensors are disposed on a side wall of a housing of the wearable device, and distances between each of the at least two pressure sensors and the touch structure are different; determining whether all the pressure values acquired by the pressure sensors are in a predetermined reference pressure range. If all the pressure values acquired by the pressure sensors are in the predetermined reference pressure range, respond to an event that the touch structure is triggered, and if not all the pressure values acquired by the pressure sensors are in the predetermined reference pressure range, determine that the touch is false triggering.

Abstract: Disclosed is an accidental touch prevention method applied to a wearable device including a touch control structure and a capacitive touch sensor configured to collect capacitance values of at least two touch channels. The distances between the touch channels and the touch control structure are not equal. The method includes: when an event of triggering a touch control structure is detected, obtaining a capacitance value of each touch channel collected by the capacitive touch sensor; determining whether the capacitance values of all of the touch channels meet a preset capacitance value distribution state which is the distribution state of the capacitance values of all of the touch channels when the touch control structure is triggered under the conditions of a non-accidental touch; and if not, determining that the touch control structure has been touched accidentally, and not responding to the event of triggering the touch control structure.

Abstract: A method and circuit for controlling an earphone, and a smart wrist-mounted device are provided. The method is applied to a wireless earphone including an earphone charging chip and an earphone Bluetooth chip. With the method, a power supply line between the earphone charging chip and the earphone Bluetooth chip remains in a connected state when it is detected that the wireless earphone is placed in the charging base, and the power supply line is disconnected when it is detected that the charging base is charging the wireless earphone to turn off the wireless earphone.

Abstract: An intelligent stereo garage system based on Internet+ and a vehicle parking and pick-up method. The system includes a mobile APP (10), a cloud server (20), a computer system (30), a programmable logic controller (PLC) system (40), a stereo garage (50), and an all-in-one touch machine (60), where the all-in-one touch machine (60) is deployed next to the stereo garage (50), and the computer system (30) is deployed outside or inside the stereo garage (50). A fully-automatic parking method uses different parking and pick-up modes, which technically ensures that users can get their vehicles in time without hindering other users, and allows users to truly experience the system intelligence. This deeply embodies the smart city's idea of interconnecting everything with a mobile phone. The method largely solves problems such as parking difficulty, illegal parking, unauthorized charges, traffic jams, traffic noise, traffic accidents, and vehicle pollution.

Abstract: Methods and apparatuses are described for automatic validation of applications on synchronized mobile devices. A server receives a command associated with a mobile application and a first image file corresponding to a current view of the application from a client computing device. The server transmits the command to a plurality of mobile devices coupled to the server. Each mobile device accesses the application and performs the command against the application. The server receives a second image file from each mobile device that corresponds to a current view of the mobile application on the mobile device. The server extracts a first set of text segments from predefined areas of the first image file and second sets of text segments from predefined areas of each second image file. The server compares the first set and each second set to determine whether a difference exists between the first set and each second set.
