Abstract: The present invention provides a variable mass elevator apparatus and method of operation, wherein the apparatus comprises an electronic scale, an elevator car, a traction sheave, a control computer, a mass storage area, a mass, a mass conveyor, a floor control panel outside of the elevator. When a passenger desires to operate the elevator, the passenger steps on the electronic scale and chooses a floor on the floor control panel, wherein the floor control panel has buttons for each floor. The electronic scale relays the weight of the passenger to the control computer, and the floor control panel relays the desired floor to the control computer. The control computer instructs a mass conveyer to couple a mass corresponding to the weight of the passenger to the elevator cable to act as a counterweight and equalize the potential energy of the elevator according to the desired floor of the passenger and the weight of the passenger.

Abstract: The present invention discloses a system and method for distributed power generation. The system comprises a power generation apparatus, a smart grid, and a bank. The power generation apparatus comprises an identification circuit, a personal generator, and an exercise equipment. The identification circuit identifies the user and the power generator converts user work into electricity. The power generation apparatus transmits the user's identity and generated electricity to the smart grid. The smart grid calculates a financial compensation according to the generated electricity and transmits the financial compensation according to the user identity.

Abstract: A global constant temperature and pulley conduit transportation network with intelligent control system includes some air inlets, some temperature detectors, some fans, some pressure detectors, some covers for air inlets, some filters, some personal door conduits, some sub-conduits, a main conduit, some seat-associated control computers, and some recumbent seats attached to bottom rollers, so that the personal door conduit connects to a plurality of residential buildings via the main conduit, and the recumbent seat is transported from a residential building entrance through the personal door conduit and main conduit to a destination under the automatic control of the seat-associated control computer.

Abstract: A detection method and apparatus is provided. The detection apparatus includes at least two angular mounted lasers, a surface for receiving laser lines emitted by the angular mounted lasers, a camera for detecting a laser pattern formed by the laser lines on the surface, and a processor for analyzing the laser pattern. The lasers emit orthogonal laser lines on a surface of the device. The camera detects a laser pattern on the surface of the device and the processor analyzes the laser pattern to determine whether the position of the device is in pocket based on the analysis and position algorithms.
