32 results about "Convenience function" patented technology

A convenience function is a non-essential subroutine in a programming library or framework which is intended to ease commonly performed tasks. These convenience functions may be added arbitrarily based on the creator's perception of what these menial tasks will be, or they may be the result of a process of refactoring by the developers and community feedback on what could be made into a convenience function. A convenience function's task may almost always be expressed in terms of other operations, though this will likely have increased verbiage and reduced abstraction and possibly maintainability. From this perspective, any programming language above assembly language is a 'convenience language' to avoid writing machine code.

Map display method and device for LED lamp on virtual display terminal

The invention relates to a map display method and device for an LED lamp on a virtual display terminal. The method comprises the steps that a stair room plane layout is obtained, mesh generation is conducted on the stair room plane layout, a coordinate reference system of a room building skeleton map is established, the coordinate positions of all LED lamps are converted and quantized, and the LED lamps are drawn. The map display method and device solve the problems that of the geographical limitation and functional limitation of control over existing LED lamp products in the prior art, and the difficult identification of individuals on cluster control occasions, a distance locating technology is combined, the convenient function that direct locating and addressing are conducted on the LED lamps through a map, and a user can accurately locate and control the LED lamps at actual corresponding geological positions through the identification on the map. Under the map presentation mode, the user can more visually mark and feed back the contrast relations of real physical individuals and marks on the map, and the target unit needing to be controlled can be rapidly and conveniently addressed simply according to a physical reference and the marks on the map.

Guide board based on solar energy

A guide board based on solar energy comprises a base. The base is fixedly connected with the ground through anchor bolts. A supporting column is fixedly connected with the middle of the upper side ofthe base. A guide board body is fixedly connected with the top end of the supporting column. A supporting sleeve is fixedly connected with the top end of the guide board body. The upper portion of thesupporting sleeve is fixedly connected with a solar photovoltaic plate support. A rotation driving device is arranged in the supporting sleeve. The top of the rotation driving device is fixedly connected with an advertisement board. The rotation driving device comprises a rotating rod. The bottom end of the rotating rod is rotationally connected with the bottom closed end of the supporting sleeve. The lower portion of the rotating rod is fixedly connected with a driven bevel gear. The guide board has the advantages that solar photovoltaic plate can have energy conservation and environment protection effects during power generation and meanwhile can supply power to lamps in the guide board; a driving bevel gear the driven bevel gear to rotate, the driven bevel gear drives the rotating rodto rotate, and therefore the rotating rod drives the advertisement board to rotate, and the guide board has flexibility and convenience functions.
