  • Publication number: 20190171737
    Abstract: A method and/or system for managing a database that stores space-time context objects is provided. The system receives a query range in a multi-dimensional space. The system maps the query range into a set of fragments of a space-filling curve that fills the multi-dimensional space in all dimensions of the multi-dimensional space. The system uses each mapped fragment in the set of mapped fragments as a key to query the database for space-time context objects that are mapped to the space-filling curve. The system queries the database by identifying one or more context objects that intersect the mapped fragment at the space-filling curve.

  • Patent number: 10309436
    Abstract: Provided is a single-groove and short-tail pulling rivet and an erection method thereof, and the pulling rivet comprises a single groove and a short tail having a broached groove with a continuous and smooth cambered surface, and is characterized by easy manufacturing, low cost and convenient erection. The broached groove is an arc surface with three sections of different radiuses, which solves stress concentration and sticking of a single-groove and short-tail rivet during riveting, and allows a claw of a riveting machine to be engaged to the best position automatically. The tooth profile of a locking groove section of the rivet is a curve combining an arc and a straight line, which greatly improves fastening force.

  • Publication number: 20190094873
    Abstract: The present invention discloses a mobile unit, an inventory management system, and a method for mobile unit localization. Sensors are immovably disposed in the workplace, actively identifying the positions of the mobile units. The individual sensor disposed in the workplace can monitor the positions of a plurality of mobile units simultaneously, and the number of sensors is only related to the size of workspace, which is independent of the number of mobile units. Since no complicated position calculations are needed for the mobile units, it reduces the requirements for on-board processors, which is more advantageous to monitor the preexisting non-automated vehicles or retrofit them into automated vehicles. With the method of the present invention, position calculations are not carried out on the bodies of AGVs, the requirements for the on-board controllers of AGVs are low, and it is easier to retrofit the non-intelligent mobile units, and thereby position monitoring and autonomous operation are implemented.

  • Publication number: 20180333869
    Abstract: The present invention discloses a safety protection method of dynamic detection for mobile robots. The mobile robot is provided with a sensor. Said sensor obtains the obstacle information in the detection areas in front of a mobile robot, and the mobile robot is caused to progressively slow down and dynamically adjust the detection area when an obstacle appears in the detection area. If no obstacle is detected in the detection area after adjusting, then the mobile robot is caused to keep on moving, and if an obstacle is still detected in the detection area after adjusting, then the mobile robot is caused to keep on decelerating until they are stopped. The sensor sets different detection areas according to the traveling speed and traveling direction of the mobile robot, or presets the detection area according to the path and dynamically adjusts it when the mobile robot is running.
