Abstract: Disclosed is a thermal-based automatic roller tracking and mapping system for roller path tracking and mapping in pavement compaction. Accuracy in estimation during roller position tracking and mapping for pavement compaction through the use of thermal imaging is achieved. The tracking and mapping system utilizes an infrared camera for automatic roller path tracking and mapping in pavement construction. The tracking and mapping data associated with the movement of the roller vehicle during compaction of the surface can be generated and visually represented in a user interface accessible to the operator of the roller vehicle. Based on the tracking and mapping data that is generated in real-time and presented to the operator in the user interface, the operator can make adjustments to the roller vehicle and path, as necessary.

Two of the pole groups on a farthest edge are provided with pole posts penetrating through the intermediate cover. The intermediate cover is fixed with two connection terminals. Each of the connection terminals comprise a first connecting part connected to the pole post and a second connecting part connected to an external wire. The two connection terminals are provided on a side of the intermediate cover in a width direction of thereof, and the second connecting part is led out from a side surface of the intermediate cover. One of the connection terminals is directly connected to one of the pole posts, and the other one of the connection terminals is connected to another one of the pole posts via an adapted cable.

Abstract: A thickened robot joint transmission structure comprises a shell, dual gear rings and a planet carrier, wherein the planet carrier is fixed to the shell through a crossed roller bearing. Planet gears are dual thickened planet gears free of a sun gear. The input ends are a pair of gears or spiral bevel gears with a variable velocity ratio and are fixed to the shell through deep groove ball bearings. The dual thickened planet gears serve as a hollow for a cable, a related shaft or a line object to pass through after the sun gear is removed.

Abstract: The present invention relates to the technical field of chemical engineering and catalysis. Provided are an application of an ionic liquid in propylene glycol ether synthesis and a method for synthesizing a propylene glycol ether. The ionic liquid is a methyl carbonate ionic liquid, and is used as a catalyst for catalyzing propylene glycol ether synthesis. The method for synthesizing the propylene glycol ether comprises the following steps: placing propylene oxide and an alcohol within a reactor to contact a catalyst, and heating the mixture in an enclosed environment to 50-200° C. to obtain the propylene glycol ether, wherein the catalyst is a methyl carbonate ionic liquid. The method for synthesizing propylene glycol ether provided in the present invention is a green synthesis technique, and does not require special production equipment. The method has simple and easily controllable processes, and can be used in industrial production and applications.

Abstract: One or more techniques and/or systems are disclosed herein for backing up in-memory working store data. A first server in a plurality of connected servers detects a data change for a key-value pair the distributed in-memory working store. The first server determines a backup location for storing a copy of the key-value pair, which is comprised on a backup location server from the plurality of connected servers, by using a key from the key-value pair to identify the backup location server, and determine if the backup location server is available to store the backup copy. The first server sends the backup copy to the backup location server without prior permission from the backup location server and without subsequent feedback from the backup location server concerning the sending of the backup copy.
