The present invention is directed towards implantable, inflatable, bioabsorbable medical prostheses. In particular, the present invention relates to an implantable, inflatable, bioabsorbable method and device for occluding septal defects such as an atrial septal defect. A double button shaped device is contained in a catheter to allow for easy positioning and re-positioning of the apparatus to ensure proper placement and deployment. The device is charged with a filling solution so that it temporarily stabilizes the defect for a period of time typically varying from weeks to a year while it provides a structure to support natural tissue growth. The device is eventually replaced by natural tissue as it degrades and is absorbed or eliminated from the body by natural processes.

The present invention uses specific cultivation system and method to produce vegetables with a nitrate nitrogen (NO3—N) concentration below 450 ppm (NO3—N (mg / kg)≦450 ppm). An advanced water cultivation system and a scheduled nutrient injection and removal method are used to achieve the specification of a nitrate nitrogen concentration less than 450 ppm. The nutrient supply and recycle system sets a time period prior to harvest to recycle nutrients and consume the nitrate nitrogen of the vegetables by supplying fresh water only, so that nitrate nitrogen remained in the vegetables can be consumed completely by the natural process of photosynthesis and the nitrate nitrogen concentration of these vegetables is much below those produced by traditional farming, water cultivation, organic cultivation or wildlife or those cannot achieve a low nitrate nitrogen under natural conditions. The invention is definitely a breakthrough on the quantitative control of harmful ingredients.

System and method for detecting the authenticity of products by detecting a unique chaotic signature. Photos of the products are taken at the plant and stored in a database / server. The server processes the images to detect for each authentic product a unique authentic signature which is the result of a manufacturing process, a process of nature etc. To detect whether the product is genuine or not at the store, the user / buyer may take a picture of the product and send it to the server (e.g. using an app installed on a portable device or the like). Upon receipt of the photo, the server may process the receive image in search for a pre-detected and / or pre-stored chaotic signature associated with an authentic product. The server may return a response to the user indicating the result of the search. A feedback mechanism may be included to guide the user to take a picture at a specific location of the product where the chaotic signature may exist.

An apparatus and method for electrically induced thrombosis. The surgical device includes a first electrode and a second electrode. The first electrode is for placement adjacent to, near, or within a treatment site of a patient. The second electrode can be movable with respect to the first electrode. When the electrodes are charged by an electricity source, negatively charged blood components are attracted to the positively charged electrode while being repelled from the negatively charged electrode. Due to the electric potential between the adjacent electrodes, thrombosis is induced. The negatively charged blood and components form a thrombus or a clot adjacent to the positively charged electrode. The surgical device can be used to induce the otherwise natural process of thrombosis. When the surgical device is used in a treatment site such as a puncture or incision, the thrombosis can seal the opening created by the treatment site.

An apparatus and method simulates more accurately the natural statistics of a physical reverberation process. A new filter design is provided having a comb shaped group delay. Gain minimums at a plurality of frequencies are combined with a delay line to create a constant reverberation time independent of frequency while allowing for temporal spreading. In addition, the connection topology between the plurality of energy transmission networks is temporally randomized to facilitate energy distribution within the reverberation apparatus. Both the temporal and spectral responses are actively changed on each iteration of the energy recirculation. By making the response have a high echo density and a lack of spectral coloration in the decay, the illusion of a natural process is enhanced.

Compositions, methods, and kits are provided for efficiently generating and screening humanized antibody with high affinity against a specific antigen. The library of humanized antibody is generated by mutagenizing a chimeric antibody template that combines human antibody framework and antigen binding sites of a non-human antibody. Alternatively, the library of humanized antibody is generated by grafting essential antigen-recognition segment(s) such as CDRs of the non-human antibody into the corresponding position(s) of each member of a human antibody library. This library of humanized antibody is then screened for high affinity binding toward a specific antigen in vivo in organism such as yeast or in vitro using techniques such as ribosome display or mRNA display. The overall process can be efficiently performed in a high throughput and automated manner, thus mimicking the natural process of antibody affinity maturation.

The present invention relates to a method and apparatus intended for the detection of low frequency electric waves that can be extracted from water, organic liquids and biological matter. This field phenomenon, that we here refer to here as a “bioharmonic”, is an active frequency, or harmonically related series of frequencies, that are a result of a dynamic interplay of natural processes including physical, chemical and electromagnetic interactions. We have discovered that these interactions influence the organization of signal waveform characteristics at very low frequencies. The apparatus produces a low frequency electrical wave that is coupled to a liquid or solid sample by way of a coupling electrode having a very high impedance. As the detected signal also displays field properties, the electrode does not need to be in contact with the sample in order to extract a unique signal. The resultant signal is rectified and passed through a logic gate where it is conditioned using a low pass filter on the gate output stage before amplification. A darlington type transistor is used to amplify the signal by a minimum factor of twenty thousand.
