A shoulder rest structure for a violin and a viola is disclosed. The shoulder rest structure comprises a first body and a second body. The first body has a positioning piece in which the positioning piece has a first connecting part and a first counterpart connected to two ends thereof. The first connecting part connects at least one first adjustment piece; the first counterpart connects at least one second adjustment piece. The second body has a first side and a second side; the first side of the second body attaches to the first body correspondingly. By means of the ergonomic design of the present invention, the violin/viola practice is made more comfortable and the length of the shoulder rest can be adjusted by the user according to requirements.

A clamping device for holding shoulder rest to violin and viola includes a holding member, a plurality of clamping members, and a shaft. The holding member has a base portion and an extended portion outward extended from the base portion. The clamping members are connected to the extended portion. The shaft is extended through the clamping members and the extended portion. With these arrangements, a shoulder rest can be very conveniently assembled to a violin or a viola and can be freely adjusted in angle for use.

A secure real-time data replication system includes a key management server that provides keys to hosts that store encrypted data. Data to be written in one host is encrypted using a key received from the key management server; the encrypted data is stored in the host. A copy of the data is provided to another host for real-time data replication. In the other host, the copy of the data is encrypted using another key received from the key management server; the encrypted copy of the data is stored in the other host. Keys are provided by the key management server based on policy rules governing the keys.

A series of digit processing units (DPUs) are connected to form a finite impulse response (FIR) filter. Each DPU includes a register, a multiplexer, and a coefficient multiplier. The register stores and delays an input digital signal to be filtered. The multiplexer has inputs connected to the input node and to an output of the register, an output of the multiplexer for connecting to a next stage DPU. The coefficient multiplier is connected to the output of the register and multiplies the input signal by a coefficient or part of a coefficient. A group of DPUs can have multiplexers set so that the register of each DPU stores the same part of the input signal for processing a single filter coefficient. An adder is provided to sum output of the DPUs and output a filtered signal. The critical path of the FIR filter is independent of coefficient number and precision.

A linear/non-linear adaptive filter for transforming an input signal to an output signal. The present invention also includes a novel GSPT LMS algorithm for significantly reducing complexity. The adaptive filter includes a coefficient updater that can execute a Carry-in operation or a Borrow-in operation to adaptively adjust a filtering coefficient according to whether an updating term signal is a Carry-in signal or a Borrow-in signal.
