## Background
TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a method for operating an air mattress pressure controller and a structure thereof, and particularly to a low cost regulation method for efficiently adjusting parameters for effecting air charging for an air mattress and an air mattress pressure controller constructed on the basis of the method.
DESCRIPTION OF THE PRIOR ART
The earth natural resources are being depleted. The fossil energy that has been long relied upon by the human society is over-consumed and may get used up earlier than expected.
A solution to the depletion of the fossil energy is to develop new energies. However, no breakthrough has emerged so far. Thus, more complete exploitation of the current natural energy resources is a more feasible and practical way for the time being. An example is to develop new sources for supplying of electricity.
Traditionally, the mainstream sources of electricity are obtained with thermal power generation, hydraulic power generation, wind power generation, and even nuclear power generation, among which the thermal power generation is effected by combusting coals, which is not economic for areas where no coal mine is present and which causes severe air pollution. Nuclear power generation is considered a high technique field, which poses certain obstacles to low technique countries and may be subject to severe potential risks of radioactive pollution. Thus, wind power generation and hydraulic power generation are the most acceptable options to most of the countries of the world.
Both wind power generation and hydraulic power generation require a turbine that is rotated by wind power or hydraulic power to drive a dynamo for generating electricity. Hydraulic power generation requires a dam to retain water, and this is extremely expensive and is limited in lifespan. The most advanced technique for generating electricity is to retrieve kinetic energy from waves of seas or oceans. Since sea waves are generated naturally, the kinetic energy of sea waves is almost unlimited. However, although the movement of sea waves is seemingly in a fixed direction, the actual movement of sea waves is practically a linear forth-and-back motion. Conventional turbines are set at a fixed orientation and the blades of the conventional turbines are arranged at fixed inclined angles, both factors making it impossible to perfectly align the turbine with the moving direction of sea waves.
SUMMARY OF THE INVENTION
Thus, an objective of the present invention is to provide a tidal power generation device, which includes at least a chassis, a rail frame, and a chain support rack. The rail frame is set at one side of the chassis in an inclined fashion. A driver arranged on the rail frame at an end thereof includes a connection bar and a float arranged at a front side thereof. The chain support rack is mounted on the chassis and the chain support rack is set in an inclined fashion. Two toothed wheels are respectively mounted to opposite end portions of the chain support rack for supporting and operative coupling with a chain. The connection bar of the driver is coupled to the chain. The low-side toothed wheel has a centrally arranged shaft that is supported by a one-way bearing and operatively coupled to a first transmission axle through mated gears mounted to the shaft and the first transmission axle. The first transmission axle is in operative coupling with and drives a second transmission axle, which is coupled to a dynamo. By installing the power generation device at a sea shore to allow the driver to be forced by sea waves to advance frontward, the connection bar is moved frontward to cause movement of the chain, which in turns drives rotation of the toothed wheels and the shaft, whereby the gear of the shaft drives the first transmission axle, which in turn drives the second transmission axle to operate the dynamo for generating electricity.
The foregoing objective and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
With reference to the drawings and in particular to FIG. 1, a tidal power generation device 1 constructed in accordance with the present invention comprises at least a chassis 2, a rail frame 3, and a chain support rack 4.
The chassis 2, which serves as a base, connects and supports the rail frame 3 and the chain support rack 4.
The rail frame 3 is set at one side of the chassis 2 and extends from the chassis 2 in a downward inclined direction. The rail frame 3 movably carries a driver 31 that forms an opening 311 and a float 312 set at a side of the driver 31 opposite to the opening 311. A plurality of first rollers 313 is mounted to a bottom of the opening 311. The first rollers 313 are movably received in rail slots 314 defined in the rail frame 3. The rail slots 314 properly position the driver 31. A connection bar 315 extends from a front side of the driver 31 and has a free distal front end to which a connector 316 is mounted. The connector 316 is operatively coupled to a chain 43.
As shown in FIG. 2, the chain support rack 4 is set on a top of the chassis 2 in an inclined arrangement. Opposite end portions of the chain support rack 4 are respectively provided with toothed wheels, respectively referred to as low-side wheel 41 and high-side wheel 42. The toothed wheels 41, 42 are operatively coupled to the chain 43 to be driven thereby and interconnecting with each other. A second roller 431 is mounted under the connection between the chain 43 and the connector 316 of the connection bar 315, for also providing a support to the connection bar 315 that is located beside the chain 43, and is reciprocally movable along the chain support rack 4. The low-side toothed wheel 41 has a centrally arranged shaft 411 that is mounted to the chain support rack 4 by bearings and carries a gear 412 that mates a gear 451 mounted to a first transmission axle 45. The first transmission axle 45 drives a second transmission axle 46. Both the first transmission axle 45 and the second transmission axle 46 are supported on a coupling frame 47 by bearings. The coupling frame 47 serves to couple the second transmission axle 46 to a plurality of subsequent power generation devices 1 of the same construction, such as 10-15 power generation devices 1, as illustrated in FIG. 3. The power generation devices 1 are set in a cascade stepwise arrangement, wherein one of the power generation devices 1 is coupled to a dynamo 5, preferably with a flywheel 6 coupled between the dynamo 5 and the one of the power generation devices 1 to maintain smooth and continuous operation of the dynamo 5 by means of the inertia force of the flywheel 6.
To practice, as shown in FIGS. 4-6, in which only one set of the power generation device 1 of the present invention is illustrated for explanation, the power generation device 1 of the present invention is installed at a sea shore with the rail frame 3 extending into the sea water. The driver 31 carried by the rail frame 3 floats on the sea water by means of the float 312. The operation of the power generation device 1 is effected by having the driver 31 receiving and driven by waves of the sea water to advance frontward. When the driver 31 advances frontward, the connection bar 315 is caused to move frontward and drives the movement of the chain 43, which in turn rotates the toothed wheel 41 about the shaft 411, whereby the gear 412 mounted to the shaft 411 causes the first transmission axle 45 to rotate and in turn drives the rotation of the second transmission axle 46. The second transmission axle 46 then transmits the torque to the next-stage power generation device 1. The remaining power generation devices 1 operate in the same way to allow the drivers 31 thereof to be pushed frontward by receiving sea waves. Ultimately, all the torques from the power generation devices 1 are transmitted to the dynamo 5, by which the dynamo 5 generates and outputs electricity.
The present invention uses sea waves to make the driver 31 of the power generation device 1 advancing frontward and when the wave retreats, the driver 31 returns to the sea surface. The shaft 411 is coupled to the chain support rack 4 by one-way bearings 44, and thus the first transmission axle 45 only rotates with the frontward movement or advancing of the driver 31 and is not rotated by the chain 43 and the toothed wheel 41 when the driver 31 is returning back to the sea surface. To maintain continuous generation of power during the time period when the driver 31 is returning to sea surface, as illustrated in FIG. 7, a third transmission axle 48 is additionally provided at a location adjacent to the first transmission axle 45. The first transmission axle 45 and the third transmission axle 48 are respectively provided with gears 452, 481 that mate each other. The shaft 411 is also provided with a gear 413 that drives the rotation of the third transmission axle 48. The gear 413 is supported by a one-way bearing 44′ in such a way that the third transmission axle 48 is rotated by the gear 413 only when the driver 31 is moving back to the sea surface and the rotation of third transmission axle 48 is transmitted to the gear 452 for subsequently driving the first transmission axle 45 to rotate the second transmission axle 46 and transmitting the torque to the dynamo 5.
The effectiveness of the present invention resides in that an impact force caused by sea waves is employed to frontward advance the driver 31 of the power generation device 1, which in turns moves the connection bar 315 for causing the movements/rotations of the chain 43, the first transmission axle 45, and the second transmission axle 46 simultaneously to thereby apply torque to the dynamo 5. A rotor of the dynamo 5 is thus rotated and electricity is generated. In this way, both electricity generation and environmental conservation can be realized at the same time.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
