Abstract: A robot system, including: a robot; a base supporting the robot; a controller connected to the robot; a processor connected to the controller; a depth camera connected to the processor; a flange plate; a coupling shaft including a first end and a second end; a mounting base including an elongated hole, a first side wall, and a second side wall; a sprayer including a mounting shaft; a first positioning bolt; a limit arm includes a first end and a second end; an axis pin; a limit shaft; a second positioning bolt; a gas cylinder; a piston rod; a connector; a shifter level; a trigger. The robot is connected to the first end of the coupling shaft via the flange plate. The second end of the coupling shaft is connected to the mounting base. The mounting shaft of the sprayer is disposed in the elongated hole of the mounting base.

Abstract: A device providing intelligent assistance in mobility for disabled people and others includes a mobility device and a lifting device detachably mounted on the mobility device. The lifting device includes a base frame, a retractable bracket structure, several wheels, a sitting pad, and a backrest. The wheels are mounted on a lower surface of the base frame and drive the lifting device to move. The retractable bracket structure is mounted on an upper surface of the base frame. The sitting pad is detachably mounted on the retractable bracket structure, and the backrest is rotatably mounted on the retractable bracket structure.

Abstract: Historical usage data related to user queries and training properties for a plurality of web pages is received and utilized to train a mathematical model to predict the likelihood of retrieval of a web page during a web search. Properties are extracted from the plurality of web pages in the index and the mathematical model is applied to the properties for each web page to calculate a sortrank value. The index is reordered based on the sortrank value such that the web pages most likely to be retrieved by a user submitting a search query appear first in the index. After a search query is received from a user the index is traversed in an order determined by the sortrank value. Responsive web pages are presented to the user in an order determined by a search engine ranking algorithm.
