Abstract: The present invention relates to a system and a method for energy-saving air conditioning control via QR (Quick Response) code. The system and the method for air conditioning control according to the present invention using a QR code generated in the vicinity of a location of an air conditioning apparatus or a group of air conditioning apparatuses corresponding to a predetermined space to be cooled. To control the air conditioning apparatus or the group of air conditioning apparatuses, the user needs to be at the position where a QR code is attached to scan the QR code combined with a valid user identifier to access an air conditioning control interface with one or more than one predetermined air conditioning control mode corresponding to the air conditioning apparatus or the group of air conditioning apparatuses associated with said scanned QR code.

Abstract: A method and apparatus for teaching a programmed controlled robot at least one of two set up position coordinates by use of a tool having a first surface aligned with the end of a stud welding gun collet when the tool is mounted in the collet, a second surface on the tool spaced from the first surface by a predetermined set up distance. A probe carried by the stud welding engagable with the second surface on the tool to establish a predetermined set up distance. A third surface on the tool spaced from the first surface and engagable with a work piece to establish a minimum stud-welding gun set up dimension. The coordinates of the stud-welding gun when the third surface is engaged with the work piece are transmitted to a robot control program to establish the predetermined stud weld gun travel distance dimension.
