Definition of Current Practice. Current Practice means, in respect of any action or inaction, the practices, standards and procedures of the Non-Securitization Entities as performed on or that would have been performed immediately prior to the Closing Date.

Piano and piano interactive practice device

The invention provides a piano and a piano interactive practice device. The piano interactive practice device comprises a piano keyboard detection sensor array, a signal processing unit and a display unit, wherein the piano keyboard detection sensor array is used for detecting the pressed state of the piano keyboard and generating a state detection signal of the piano keyboard; the signal processing unit is connected with the piano keyboard detection sensor array, and is used for receiving the state detection signal of the piano keyboard, providing a keystroke tip to prompt the current note to be played according to the playing content of the current practice program, comparing the state detection signal of the piano keyboard with the note to be played to judge whether a practicer is rightly playing or not, and obtaining playing judgment information; the display unit is connected with the signal processing unit, and is used for displaying playing content information of the practice program and displaying the playing judgment information. The piano interactive practice device adopts the piano keyboard detection sensor array to detect the piano keystroke state in real time and to process the fed back keystroke variation information, and adopts the display unit to prompt and rectify playing, so that the resource utilization rate of teachers is improved, and the educational cost is reduced.

Effective deployment of temporal noise shaping (TNS) filters

In the MPEG2 Advanced Audio Coder (AAC) standard, Temporal Noise Shaping (TNS) is currently implemented by defining one filter for a given frequency band, and then switching to another filter for the adjacent frequency band when the signal structure in the adjacent band is different than the one in the previous band. The AAC standard limits the number of filters used to either one filter for a “short” block or three filters for a “long” block. In cases where the need for additional filters is present but the limit of permissible filters has been reached, the remaining frequency spectra are simply not covered by TNS. This current practice is not an effective way of deploying TNS filters for most audio signals. We propose two solutions to deploy TNS filters in order to get the entire spectrum of the signal into TNS. The first method involves a filter bridging technique and complies with the current AAC standard. The second method involves a filter clustering technique. Although the second method is both more efficient and accurate in capturing the temporal structure of the time signal, it is not AAC standard compliant. Thus, a new syntax for packing filter information derived using the second method for transmission to a receiver is also outlined.

System and method for processing and distributing freight containers

A system and method for optimally managing the inventory of railroad freight cars and for transporting and processing the unladen cars to reloading points. The system provides a means for returning unladen cars at one or more strategically located yards or aggregation facilities where the cars are cleaned, inspected, repaired / maintained, stored and blocked for ultimate delivery. After such processes the cars may be treated as generic, and used for the transport of any materials within the constraints of the car type, rather than being dedicated to specific products and returned to a specific production facilities as in current practice. As well, the method provides a means by which multiple car operators may pool their collective rail car assets to further optimize the rail car supply chain. The method provides a means to determine candidate locations for such aggregation facilities / processing yards, and for optimal inventory control, sorting by next destination, and transit scheduling to deliver unladen cars to their next reloading points. The system and method are particularly useful in transporting specific polymer resins to a manufacturing region and returning the rail car through the aggregation / processing facility such that the cleaned, repaired, inspected, stored and blocked car may be used at any resin production facility.
