Abstract: A system of generating, inheriting and destroying avatar attribute of real-name identity in metaverse and a method thereof are disclosed. In the system, a fungible token with an avatar attribute is generated, and the fungible token and real-name identity information are bound through the avatar attribute, so that the fungible token can represent the valid avatar in the metaverse; when the user triggers an event, one of operations of splitting, inheriting and destroying the fungible token can be selected based on the triggered event, so as to achieve the technical effect of improving the availability of real-name identity in the metaverse.

Abstract: An avatar carrier generating system for metaverse and method thereof are disclosed. Before a living body enters a metaverse, a sensing element senses the living body to generate a physiological feature, and after a real-name identity message is received, the real-name identity message and the physiological feature are converted into metadata compliant with a non-fungible token standard; the non-fungible token, which is owned by the living body, is generated on the blockchain based on the metadata. When the living body enters the metaverse, an avatar carrier for entering the metaverse is generated based on the metadata of the non-fungible token, and when the avatar carrier receives an identification request, the avatar carrier is permitted to provide at least one of the physiological feature and the real-name identity message, so as to achieve the effect of improving identifiability and authentication of the avatar carrier of the metaverse.

Abstract: A charging and patrol replacement system for air-land unmanned aerial vehicles and a method thereof. In the system, an unmanned aerial vehicle in flight continuously detects a remaining battery power thereof, and when the remaining battery power is lower than a threshold, the unmanned aerial vehicle generates and transmits a return-to-home signal to an unmanned ground vehicle, the unmanned ground vehicle continuously transmits a coordinate of a power supply vehicle to the unmanned aerial vehicle in flight, to guide the unmanned aerial vehicle in flight to return to the power supply vehicle for charging, and the unmanned ground vehicle then activates another unmanned aerial vehicle to synchronize patrol data with the unmanned aerial vehicle which is returned to charge, so as to replace the returned unmanned aerial vehicle to perform patrol, thereby achieving the technical effect of improving the sustainability and synergy of the air-land unmanned vehicles.

Abstract: A near-field sensing information transmission and pairing system for air-land unmanned vehicles and a method thereof are disclosed. The unmanned aviation vehicle is driven to move along a forward route of an unmanned ground vehicle in advance, and continuously senses whether an obstacle or a traffic control appears in the forward route; when sensing the presence of the obstacle or the traffic control feature, the unmanned aviation vehicle generates and transmits a re-routing signal to the unmanned ground vehicle, an alternative route is calculated to replace the original forward route based on map information, a current coordinate, an obstacle coordinate and a destination coordinate, so as to increase a reaction time of the unmanned ground vehicle, thereby achieving the technical effect of improving immediacy of the unmanned ground vehicle to avoid a roadblock.

Abstract: A system of cooperating with multiple navigation robots for cross-floor guidance based on time and a method thereof are disclosed. In the system, a first navigation robot evaluates a movement time of a service target from a first floor to a second floor, generates a task message based on the movement time, and guides the service target on the first floor based on a first navigation route; a second navigation robot obtains a target arrival time contained in the task message and determines a delay time for reaching a floor entry area of the second floor earlier than the target arrival time, so that the first navigation robot can postpone the time of guiding the service target to a floor departure area of the first floor based on the delay time.

Abstract: A method and system for starting a multiple PDA OS through a menu is disclosed. The invention mainly modifies the BIOS booting procedure in a notebook PC installed with multiple OS's. After the notebook PC is turned on, the multiple OS's are detected. These multiple OS's, including a PDA OS and a normal notebook PC basic OS (such as the Windows OS), are displayed on a menu. By ignoring some hardware diagnostic steps during the BIOS booting procedure and only performing hardware diagnoses for those input devices that support menu manipulations, the starting speed of the laptop can be accelerated. The user can thus start any OS by clicking the desired item in the OS menu.

Abstract: The specification discloses a method and system for directly starting a PDA OS on a portable PC using a hardware device. Through the design of a hardware PDA starting element (such as a hot key), refreshing the BIOS bootstrap, and a built-in PDA OS, the system can directly start the bootstrap of the PDA OS once the PDA starting element is detected to be enabled. Otherwise, the basic OS preloaded in the portable PC (such as the Windows OS) is started. By using the disclosed method users can avoid the complicated power on procedure and achieve the goal of directly starting a PDA OS by the hardware of the invention.

Abstract: A method for browsing on-line using numeric keys is provided. The present method comprises the steps of: sorting a plurality of hyperlinks displayed on a web page, marking each of the plurality of hyperlinks with a corresponding number, and connecting to and displaying another web page linked with the hyperlink in response to an input number.
