20110197740 | Novel Karaoke and Multi-Channel Data Recording / Transmission Techniques via Wavefront Multiplexing and Demultiplexing - An advanced channel storage and retrieving system is achieved that is capable of simultaneously transporting multiple-stream data concurrently, with encryptions and error detection and limited correction capability using wavefront (WF) multiplexing (muxing) at the pre-processing and WF demultiplexing (de-muxing) in the post-processing. The WF muxing and demuxing processing can be applied for multiple signal streams with similar contents and format such as cable TV delivery systems or multiple signal streams with very distinct contents and format such as Karaoke multimedia systems. The stored or transported data are preprocessed by a WF muxing processor and are in the formats of multiple sub-channels. Signals in each sub-channel are results of unique linear combination of all the input signals streams. Conversely, an input signal stream is replicated and appears on all the sub-channels. Furthermore the replicated streams in various sub-channels are “linked” together by a unique phase weighting vector, which is called “wavefront” or WF. Various input signal streams will feature different WFs among their replicated signal streams in the sub-channels. The WF muxing processing is capable to generating a set of orthogonal WFs, and the WF demuxing processing is capable of reconstituting the input signal streams based on the retrieved sub-channel data only if the orthogonal characteristics of a set of WFs are preserved. Without the orthogonality among the WF, the signals in sub-channels are mixed and become effectively pseudo random noise. Therefore, an electronic locking mechanism in the preprocessing is implemented to make the WFs un-orthogonal among one another. Similarly, an electronic un-locking mechanism in the post-processing is implemented to restore the orthogonal characteristics among various WFs embedded in the sub-channel signals. Some of the phenomena due to the selected locking mechanisms are reproducible in nature, such as wave propagating effects, and other are distinctively man-made; such as switching sub-channel sequences. There are other conventional encryption techniques using public and private keys which can be applied in conjunction with the WF muxing and de-muxing processor, converting plain data streams into ciphered data streams which can be decoded back into the original plain data streams. An encryption algorithm along with a key is used in the encryption and decryption of data. As to the optional parallel to serial and serial to parallel conversions in the pre and post processing, respectively, we assume that transmissions with single carrier are more efficient than those with multiple carriers. We also assume single channel recording is more cost effective than multiple channel recording. However, there are occasions that continuous spectrum is hard to come-by. We may use fragmented spectrum for transmissions. There are techniques to convert wideband waveforms using continuous spectra into multiple fragmented sub-channels distributed on non-continuous frequency slots. Under these conditions we may replace the parallel to serial conversion processing by a frequency mapping processor. | 08-18-2011 |
20120057716 | Generating Acoustic Quiet Zone by Noise Injection Techniques - A quiet zone generation technique for acoustic/audio signals is proposed for mitigation of selected noise or interferences over limited areas in free space by injecting the very acoustic noise, interference, or audio feedback signals via iterative processing, generating quiet zones dynamically. This creates undesired noise-free quiet zones. Optimization loops operating iteratively to electronically process cancellation signals consist of three interconnected functional blocks: (1) an acoustic injection array, consisting of pick-up arrays to obtain the interference signals, beam forming networks for element weighting and/or re-positioning, and array elements for noise injections, (2) a diagnostic network with strategically located probes, and (3) an optimization processor with cost minimization algorithms to calculate element weights for updating. | 03-08-2012 |

The receive antenna may feature multiple receiving apertures distributed over a finite area. Optimization loops consist of four cascaded functional blocks; (1) a pick-up array to obtain the interference signals, (2) element weighting and/or repositioning processors, (3) an auxiliary transmit (XMIT) array with optimized element positions, (4) a diagnostic network with strategically located probes, and (5) an optimization processor with cost minimization algorithms. | 03-08-2012 |

20130333544 | Novel Karaoke and Multi-Channel Data Recording / Transmission Techniques via Wavefront Multiplexing and Demultiplexing - 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. Post-processing via a wavefront de-multiplexer converts various sub-channel signals back to the original data streams, utilizing the embedded probing signals to restore orthogonality among multiple wavefronts. | 12-19-2013 |
20140081989 | WAVEFRONT MUXING AND DEMUXING FOR CLOUD DATA STORAGE AND TRANSPORT - 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. In addition, WF muxing/demuxing methods enable a monitoring capability on the integrity of stored data. | 03-20-2014 |

20140377760 | METHOD FOR INCREASING NUMBER OF STEM CELLS IN HUMAN OR ANIMAL BODIES - 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. | 12-25-2014 |
20150040184 | Digital Enveloping for Digital Right Management and Re-broadcasting - Data files with digital envelops are used (1) for embedded identifiers for digital right management (DRM), and (2) as means delivering additional data or new information via repeated re-broadcasting process by many broadcasting service providers. The new DRM applications offer additional privacy and survivability while data is in storage and/or transported on cloud. 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. 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. In short, digital enveloping/de-enveloping can be implemented via WF muxing and demuxing formulations. WF muxed data featured enhanced privacy and redundancy in data transport and storage on cloud. On the other hand, data enveloping is in a different application domain from most of WF muxing applications as far as redundancy is concerned. Enveloped data is intended only for limited receivers who has access to associated digital enveloped data files with enhanced privacy for no or minimized redundancy. | 02-05-2015 |
