Abstract: The invention is directed to an apparatus for producing demineralized osteoinductive bone. The apparatus demineralizes bone by subjecting bone, including, for example, ground bone, bone cubes, chips, strips, or essentially intact bone, to either a rapid high volume pulsatile acidification wave process or to a rapid continuous acid demineralization process. The pulsatile acidification wave process includes subjecting bone to two or more rapid pulse/drain cycles in which one or more demineralizing acids is rapidly pulsed into a vessel containing bone, and after a desired period of time, is rapidly drained from the vessel. The continuous acid demineralization process includes subjecting bone to a continuous exchange of demineralizing acid solution in which the demineralizing acid solution is recirculated from the container holding the bone through an ion exchange media.

Abstract: Airway monitoring apparatus 30 includes a driver 6 for applying sound in the audible frequency range to the airway of a subject and a detector 7 for monitoring the response of the airway, e.g. by detecting transmitted sound signal components and/or reflected sound signal components. Variations in the detected sound signal, e.g. energy, due to attenuation of the signal, give an indication of the state of the airway, e.g. airway patency, and can be used to monitor sleep-disordered breathing events, such as apnea and hypopnea, and to provide a breathing event index, e.g. AHI. The apparatus may provide servo-control for a respiratory assist device, such as a positive airway pressure device, so as to provide an appropriate pressure level setting. It may allow for home use of such devices and for home titration. It may also assist in discriminating central and obstructive breathing events, and in providing a measure of airway resistance.

Abstract: An optical correlation apparatus is taught which provides a parallel optical signal having a phase modulation representing input data to which a parallel phase modulation based on reference data is applied. In the event of correlation the resulting wavefront is planar and can be interferometrically coupled to give a high intensity signal. The invention involves use of parallel amplitude modulation means for selectively blocking the optical signal in one or more of the channels of the parallel optical signal which allows different sized reference data strings to be searched more easily and also aids in calibration.

Abstract: The invention is directed to a process for producing demineralized osteoinductive bone, and demineralized osteoinductive bone produced thereby. The process achieves demineralization of bone by subjecting bone, including for example ground bone, bone cubes, chips, strips, or essentially intact bone, to a rapid high volume, pulsatile acidification wave process. The process includes subjecting bone to two or more rapid pulse/drain cycles where one or more demineralizing acids are rapidly pulsed into a vessel containing bone, and after a desired period of time, is rapidly drained from the vessel, the vessel containing the bone is then rapidly refilled with the one or more demineralizing acids (pulsed). The process allows bone to be rapidly demineralized to a precise ans specific desired residual calcium level, without sacrificing osteoinductivity.

Abstract: The invention is directed to a process for producing demineralized osteoinductive bone, and demineralized osteoinductive bone produced thereby. The process achieves demineralization of bone by subjecting bone, including for example ground bone, bone cubes, chips, strips, or essentially intact bone, to a rapid continuous acid demineralization process. The process includes subjecting bone to a continuous exchange of demineralizing acid solution where the demineralizing acid solution is recirculated from the substantially closed container through an ion exchange media to remove calcium and phosphate thereby producing a regenerated acid, and returning the regenerated acid to the substantially closed container to produce osteoinductive demineralized bone. The process allows bone to be rapidly demineralized to a precise and specific desired residual calcium level, without sacrificing osteoinductivity.

Abstract: The invention relates to the use of a secretor variant cell-line expressing the alpha moiety of human IgE binding protein to determine the allergic status of a given individual. Moreover, the cell-line is also used to provide an assay system for determining the allergenicity of substances and for subsequently providing therapeutic compostions which render said substances ineffective. In addition, the invention also relates to the use of said cell-line to determine the IgE independent irritancy of substances and compositions effective for attenuating the effects of said substances.

Abstract: A data processing system having a compression and decompression apparatus based on the Lempel-Ziv algorithm. The compression apparatus includes a history RAM unit for receiving and storing one or more data elements and a coding unit for determining whether received data elements previously have been stored in the history RAM unit and are a candidate for compression. If a received data element matches at least one of the stored data elements, an address of the matching stored data element is generated. The compression apparatus generates a compression token comprising an identification of whether a data element is compressed, the length of the coded data within a plurality of predetermined data length categories and an address. The decompression apparatus also includes a history RAM unit for storing received data elements and includes a circuit for receiving a compression token and determining the storage addresses of the next data element from the length and address information contained in the token.
