Methods and systems for storing digital data into peptide sequences and retrieving digital data from peptide sequences are disclosed. The method for storing digital data into peptide sequences may include: encoding the digital data into a digital code; translating the digital code into the peptide sequences; and synthesizing the translated peptide sequences. The method for retrieving digital data from peptide sequences may include: sequencing and determining an order of the peptide sequences; converting the peptide sequences with the determined order into a digital code; and decoding the digital data from the digital code. Codes with error-correction capability are developed for encoding digital data into peptide sequences, and a computational method implemented in a software is developed for sequencing the digital data bearing peptides.

Data storage using peptides

This invention provides a cyclically-coupled (CC-) quasi-cyclic (QC-) low-density parity-check (LDPC) code and its decoder architecture. The essence of the invention is to introduce the convolutional nature to a plurality of individual block codes internally so as to form a resultant block code with a prolonged code length while slightly increasing the hardware complexity in decoder realization. The CC-QC-LDPC code is formed by cyclically coupling a plurality of sub-codes each being a QC-LDPC code such that overlapping of some variable nodes between two consecutive sub-codes results. The decoder comprises plural sub-decoders each configured to decode the channel messages for one sub-code. The sub-decoders are arranged in a ring shape such that an individual sub-decoder is configured to communicate edge messages with two neighboring sub-decoders adjacent to said individual sub-decoder in the decoding of the channel messages. The sub-decoders are configured to operate concurrently for simultaneously decoding individual sub-codes.

Decoder architecture for cyclically-coupled quasi-cyclic low-density parity-check codes

The present invention relates a system and method to allow users to train different joints of a limb in different planes. The rotation of the system can be driven by a motor to assist or resist the motion for training purpose. By the present invention, the user can use the device to switch training between the vertical and horizontal planes, without changing the device and any module. The system is also adjustable to meet different users' body sizes.

An approximated lower-triangle structure for the parity-check matrix of low-density parity-check (LDPC) codes which allows linear-time-encoding complexity of the codes is disclosed, and the parity part of the parity-check matrix is semi-deterministic which allows high flexibility when designing the LDPC codes in order to provide higher error-correction capabilities than a typical dual-diagonal structure.

The present invention relates to devices and methods for a joint linkage device suitable for training multi-joints in a single limb. The joint linkage device is capable of rotation at a proximal end and a distal end. The device includes a proximal end having an upper plate, a middle plate, and a lower plate, a distal plate, a side bar, a main bar, a switch mechanism, and an extended bar. In use, a torque from a motor is applied to the upper plate to provide a user with an assistance torque, a resistance torque, or a assistance/resistance torque.
