  • Patent number: 10289856
    Abstract: Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. A customized set of WF muxing on multiple digital files as inputs including at least a data message file and a selected digital envelop file, is configured to guarantee at least one of the multiple outputs comprising a weighted sum of all inputs with an appearance to human natural sensors substantially identical to the appearance of the selected digital envelop in a same image, video or audio format. The output file is the file with enveloped or embedded messages. The embedded message may be reconstituted by a corresponding WF demuxing processor at destination with the known a priori information of the original digital envelope.

  • Patent number: 10264052
    Abstract: A system comprises a plurality of personal devices identified by at least one remote storage network as belonging to a user. A personal device comprises a first folder for storing a known a priori digital file, a second folder for storing a data file, a processor, and a network interface. The processor performs an M-to-M waveform multiplexing transformation on M input files, M>1, and generates M output files. Each output file comprises a respective linear combination of the M input files. The M input files comprise the data file and the known a priori digital file. Each of the M output files appears to human perception as having substantially identical visual or audio features to the known a priori digital file. The network interface sends at least M?1 of the M output files to at least one destination in the at least one remote storage network for storage.

  • Patent number: 10152524
    Abstract: Security on data storage and transport are important concerns on cloud computing. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. In short, the WF muxed data storage solution enhances data security and data redundancy by, respectively, creating a new dimension to existing security/privacy methods and significantly reducing the storage space needed for data redundancy.

  • Patent number: 9810684
    Abstract: A method of evaluating an action includes (1) obtaining a first stem-cell data related to a subject before performing the action, (2) performing the action on the subject, (3) obtaining a second stem-cell data related to the subject after performing the action, and (4) identifying the effect of the action on the subject based on the first stem-cell data and the second stem-cell data. The subject may be a human or an animal. The action may be taking a drug or taking a nutrient or dietary supplement, which may include fucoidan. Each of the first and second stem-cell data may include the count of a type or types of stem cells and/or the percentage of the type or types of stem cells and may be obtained by the same method including counting cells using a cell counter or cell counting device such as flow cytometer.

  • Publication number: 20140377760
    Abstract: A method of obtaining stem cells includes (1) a subject (such as a human or an animal) taking or being subjected to an action, (2) after the subject taking or being subject to the action, the subject waiting for a predetermined time interval (such as between 30 minutes and 2 hours), (3) after the subject waiting for the predetermined time interval, taking a tissue sample (such as a peripheral blood of the subject) from the subject, and (4) collecting the stem cells from the tissue sample. The step of the subject taking or being subjected to the action may include the subject taking a herb medicine or an object containing fucoidan. The stem cells may be configured for a dental implant surgery. The stem cells may include a CD9(+), CD349(+) cell between 0.1 and 6.0 micrometers in size and/or a Lgr5(+) cell between 0.1 and 6.0 micrometers in size.

  • Publication number: 20130333544
    Abstract: A concurrent multi-channel data process is presented to utilize wavefront multiplexing for data storage and data stream transport in a distribution network, with additional applications for multi-media recording and data communications via transponding satellites. Multiple concurrent data streams are pre-processed by a wavefront multiplexer into multiple sub-channels or wavefront components, where signals from respective data streams are replicated into sub-channels. These replicated data streams are linked via a unique phase weighting vector, or “wave-front”, which are also linked by various spatially orthogonal wavefronts. Additionally, probing signals are embedded and linked via some of the orthogonal wavefronts. Aggregated signals in sub-channels are unique linear combinations of all input data streams.
