The present invention discloses a small integrated greening device and method for recycling wastewater, including a wastewater collection system, a microorganism and plant purification system, and a reclaimed water collection and distribution system. The method includes the following process: greywater or wastewater is collected through a pipeline and enters a water collection tank of a wastewater collection part. Lifting is performed by submersible sewage pumps, such that the lifted water enters a microorganism and plant synergistic purification and greening part. Each submersible pump is controlled by one corresponding automatic water level controller to transport the treated water to the reclaimed water-use sites. The device and method provided by the present invention utilize the physical and chemical action of a filler and the synergistic purification effect of microorganisms and plants to purify the greywater, and the purified reclaimed water is used for flushing toilets, watering trees or other purposes.

A translocation-simulating loading apparatus for the gear grinding machine with the shaped grinding wheel is provided. The apparatus includes a load-receiving test piece disposed on the gear grinding machine with the shaped grinding wheel and a load-exerting component for use in loading simulation. The gear grinding machine enables linear movements along the X, Y, and Z axes, a rotary movement around the Y axis, a rotary movement C around the Z axis, and a rotary movement A around the X axis. An angle &#x3b1; is formed between the axis L of a ball seat of the load-exerting component and the X axis direction of a Y axis component and an angle formed between the normal line of a load receiving face a and the X direction of the coordinate system of the machine tool is &#x3b1;. A detection method for static stiffness distribution is provided.

Methods and apparatuses to detect spectrum inversion based on estimated frequency offset in carrier signal. In one embodiment, a receiver includes an I/Q swap module to output an in-phase component and a quadrature-phase component; a frequency offset estimator to determine an offset in carry frequency of the in-phase and quadrature-phase components; and a spectrum inversion detector coupled to the frequency offset estimator and the I/Q swap module. The spectrum inversion detector is configured to signal the I/Q swap module to swap the in-phase component and the quadrature-phase component when an absolute value of the offset in carry frequency is above a predetermined threshold.
