A mechano-electrical energy generation system generates electrical energy from the passage of a vehicle over an inclined ramp assembly. This assembly includes an incline ramp that is rotatable about an axis proximate a vehicle roadway surface, and a safety decline ramp hinged with and rotatable with the incline ramp. The incline ramp is coupled via a roller assembly to a gravity wheel that drives a flywheel coupled to an electrical generator. As a result, passage of the vehicle over the incline ramp rotates the wheel via the roller assembly and drives the flywheel so that the electrical generator outputs electrical energy. When the vehicle exits the safety decline ramp, a counterweight rotates the wheel in a reverse direction, so as to bring the incline ramp and safety decline ramp to back to their original inclined positions above the roadway surface.

Expandable reamer tools include an outer body, a fluid passageway extending through the outer body, and at least one blade configured to slide relative to the outer body between a retracted position and an expanded position in a direction oriented at an acute angle of less than ninety degrees (90°) to a longitudinal axis of the outer body. In some embodiments, the tools may include a moveable inner sleeve member configured to selectively allow hydraulic fluid pressure within the fluid passageway to act directly on the at least one blade. Methods for enlarging a borehole using such expandable reamer tools and methods for removing such expandable reamer tools from a borehole are also disclosed.

A dump apron for a dump truck, the apron pivotally mounted around a lower end of the dump opening at the rear of the dump body, and movable in response to the tilt position of the dump body between a lower flow-channeling position and a raised tailgate-securing position.

When the upper panel portion reaches a lower position and a lower panel portion reaches a slant position, the spacing between an opening and an upper wall of the upper panel portion is enlarged, and the recording medium insertion slit is opened, resulting in the condition where a recording medium can be inserted or removed.

The invention relates to a dual-carrier ABSK communication system on the basis of the same narrow-band filter, which comprises a dual-carrier ABSK modulator and a dual-carrier ABSK demodulator. The dual-carrier ABSK modulator is used for alternately modulating each data bits of a path of data sequence with a code rate of 2Rbps onto two paths of ABSK signals of which carrier frequencies respectively are fc1 and fc2 and both the code rates are Rbps; on the two paths, a T time interval is reserved between positions at which each path of '1' code element appears, i.e. the simultaneous appearance of '1' on the two paths of carrier frequencies can be completely eliminated at an initial end; and T represents a code element period of the data sequence; the dual-carrier ABSK demodulator comprises the narrow-band filter of which both left and right transition zones are very precipitous; and when the carrier frequencies fc1 and fc2 are respectively positioned at the high-slope positions of the left and right transition zones, the narrow-band filter utilizes the slope phase demodulation characteristic to convert phase information of a double-carrier ABSK receiving signal at the position of each path of code element '1' into obvious and strong parasitic amplitude modulation impact, so that an envelope detector can output an impact envelope pulse which is naturally combined into the code rate 2Rbps.
