This invention introduces a class of multi-band linear phase lapped biorthogonal transforms with fast, VLSI-friendly implementations via lifting steps called the LiftLT. The transform is based on a lattice structure which robustly enforces both linear phase and perfect reconstruction properties. The lattice coefficients are parameterized as a series of lifting steps, providing fast, efficient in-place computation of the transform coefficients as well as the ability to map integers to integers. Our main motivation of the new transform is its application in image and video coding. Comparing to the popular 8.times.8 DCT, the 8.times.16 LiftLT only requires 1 more multiplication, 22 more additions, and 6 more shifting operations. However, image coding examples show that the LiftLT is far superior to the DCT in both objective and subjective coding performance. Thanks to properly designed overlapping basis functions, the LiftLT can completely eliminate annoying blocking artifacts. In fact, the novel LiftLT's coding performance consistently surpasses that of the much more complex 9 / 7-tap biorthogonal wavelet with floating-point coefficients. More importantly, our transform's block-based nature facilitates one-pass sequential block coding, region-of-interest coding / decoding as well as parallel processing.

When an elevator is lifted, an ear blockage phenomenon occurs due to changes of an internal pressure of an elevator car. The internal pressure of the elevator car is changed repeatedly between two different pressure change rates so that a control method inducing passengers' swallow actions can effectively ease the ear blockage phenomenon. However, in existing control methods, the pressure in the elevator car needs to be repeatedly switched to be a positive pressure and a negative pressure relative to the atmospheric pressure in a short time, and problems that a structure of a control device and a control method are complex exist. When the elevator goes down, a positive pressure state in the elevator car is only used to form stair-stepping pressure control in the first half of the running time (TT0). Therefore, the pressure control device only needs to implement switchover once, that is to say, a pressurized state is switched into a pressure reducing state, and the pressure control can be realized.
