A system enabled for reliable and ordered data communication between two sets of nodes with atomic multi-point delivery and multi-point transmission, for example, extending TCP/IP is described hereon. The transmission control protocol (TCP/IP) is intended for reliable host-to-host communication [RFC 793]. The invention extends TCP's notion of host-to-host communication to symmetric group-to-group communication maintaining TCP specifications for data traffic between the groups. The current definition of, two endpoints of a TCP connection is extended to two groups of endpoints, communicating over the connection. End-points of a connection terminate at group nodes. When multiple nodes must be delivered with data, the delivery is performed atomically. Of data originating multiple nodes, optionally, a single data instance is transmitted. Each endpoint is comprised of a receiveHead and a sendHead operating independently. The receiveHead controls delivery of incoming data to application socket and sendHead controls transmission.

In a method for transferring a music signal into a note-based description, a frequency-time representation of the music signal is first generated, the frequency-time representation comprising coordinate tuples, a coordinate tuple including a frequency value and a time value, the time value indicating the time of occurrence of the assigned frequency in the music signal. Thereupon, a fit function will be calculated as a function of the time, the course of which is determined by the coordinate tuples of the frequency-time representation. For time-segmenting the frequency-time representation, at least two adjacent extreme values of the fit function will be determined. On the basis of the determined extreme values, a segmenting will be carried out, a segment being limited by two adjacent extreme values of the fit function, the time length of the segments indicating a time length of a note for the segment. For pitch determination, a pitch for the segment using coordinate tuples in the segment will be determined. For calculating the fit function and determining extreme values of the fit function for segmenting, no requirements are made to the music signal which is to be transferred into a note-based representation. The method is thus also suitable for continuous music signals.

The invention provides a light-splitting and spectrum-selecting device used for a high spectral laser radar, including a blazed grating, a micromirror array and an APD linear array. The blazed grating performs light splitting of a target echo to obtain spatially-continuous monochromatic light, and projects the spatially-continuous monochromatic light to the micromirror array. Micro reflecting mirrors in the mircromirror array are overturned for reflecting monochromatic light of different center frequency spectrums to the APD linear array for detection, wherein in the condition of overturning a single row of micro reflecting mirrors, the minimal resolution ratio spectrum is obtained, and by controlling combined overturning of multiple rows of micro reflecting mirrors, a combined spectrum can be obtained. The invention effectively improves the spectrum resolution of the high spectral laser radar.
