AERIAL DRONES / UAV’S NEWEST PATENTS AND APPLICATIONS

[EN] MANAGING UNMANNED AERIAL VEHICLE BROADCAST SIGNALS

[EN] Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

[EN] VEHICLE NAVIGATION COMBINING TRANSMITTED OBJECT LOCATION INFORMATION AND SENSOR-BASED RELATIVE OBJECT LOCATION INFORMATION

[EN] A computerized positioning system is associated with a vehicle. It is configured to perform the following method: (a) receive first information indicative transmission(s), wherein the transmission is associated with an object(s). The first information comprises item(s) of object first position information associated with the object. The item of object first position information is indicative of an object absolute position, (b) receive second position information of the object, being indicative of a second relative position of the object with respect to the vehicle, (c) determine a derived position of the vehicle, based at least on the first information and on the second position information. The derived position is capable of being utilized to facilitate a correction in a reported position of the vehicle. The reported position is based on GNSS signal(s) received by GNSS receiver(s) associated with the vehicle.

[EN] APPARATUS, SYSTEM, AND METHOD FOR ACTIVE CHANNEL SWITCHING AND SPECTRUM IDENTIFICATION IN HOSTILE RADIO FREQUENCY ENVIRONMENTS

[EN] An unmanned aerial vehicle (UAV) has a first radio configured to operate on one of a plurality of radio frequency (RF) channels, a processing and management application program interface (API), and a controller. A system for active radio frequency (RF) channel switching includes the UAV and a head end control unit in wireless communication with the UAV. A method of RF spectrum identification and mapping includes collecting RF data by the UAV within an area of operation, determining location data within the area of operation using a global positioning system (GPS) located on the UAV, and mapping the RF data of the area of operation using the location data.

[EN] DATA PROCESSING METHOD AND APPARATUS, DEVICE, PROGRAM, AND MEDIUM

[EN] Embodiments of the present invention provide a data processing method and apparatus, a device, a program, and a medium. The method comprises: presetting one or more data linked lists, wherein each data linked list consists of multiple levels of sub-linked lists, the number of data nodes in a previous level of sub-linked list is less than the number of data nodes in a next level of sub-linked list, the data nodes in the sub-linked lists other than the lowest level of sub-linked list comprise first pointers, each first pointer is used to point to a data node in a next level of sub-linked list, and a data element stored in each data node is the same as a data element stored in a data node to which the first pointer comprised in the data node points; receiving a data search request submitted by a user; and searching in the one or more data linked lists according to the data search request, and providing feedback to the user according to a search result. By means of the embodiments of the present invention, data storage and query of a skip list based on a data linked list are implemented, no contiguous memory needs to be requested, and data query time complexity is also reduced.

[EN] UNMANNED AERIAL VEHICLE CONTROL METHOD AND APPARATUS AND DEVICE

[EN] An unmanned aerial vehicle control method and apparatus and a device. The method comprises: acquiring an interference parameter, wherein the interference parameter is used for indicating an interference effect of a specific electromagnetic switch on an ESC, an unmanned aerial vehicle further comprises a nozzle, and the specific electromagnetic switch comprises an electromagnetic valve used for controlling on-off of the nozzle (21); and determining, according to the interference parameter, whether to execute a safe operation (22). According to the method, a crash accident caused by electromagnetic interference of the specific electromagnetic switch can be reduced, and the safety of the unmanned aerial vehicle is improved.
