William E. Keating has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5963859
    Abstract: A wireless communication device is provided which is capable of interfacing with a base station of a service provider and intended for occasional use without requiring a subscription with the service provider. The device uses a non-rechargeable replaceable power source with memory means non-detachably secured to and integral with said power source comprising information code for uniquely identifying said power means and a prepaid calling time period. After the prepaid calling time period of the wireless communication device is exhausted, the power source can be exchanged for a different power source having a new prepaid calling time period.

  • Patent number: 5554503
    Abstract: Methods for processing samples which may contain mycobacteria which are compatible with both conventional culturing techniques and nucleic acid analysis. It has been found that the harsh chemical treatment previously thought necessary to obtain efficient lysis can be eliminated without loss of lysis efficiency, thereby eliminating reagents which may inhibit subsequent nucleic acid-based reactions. Heat alone is sufficient to lyse mycobacteria, even in buffers which do not contain detergents, chelators, enzymes, etc. Residual reagents introduced by conventional sample processing methods for culture can be successfully removed from the processed pellet without significant loss of microorganisms by at least two washings with saline, water, or buffers compatible with nucleic acid analysis and appropriate centrifugation.

  • Patent number: 5512440
    Abstract: The invention provides a rapid process for lysing Mycobacteria. In one embodiment is provided a process for lysing Mycobacteria which comprises exposing the bacteria to a lysis effective amount of heat. A particularly effective method for providing the necessary heat is in the form of forced hot air such as in a forced hot air oven. The process of the invention is particularly advantageous since only one step is involved, it is expedient compared to prior methods, and little instrumentation is necessary. By practicing the present invention it is possible to lyse Mycobacteria with minimal effort. In addition, practicing the invention results in liberating cellular components including deoxyribonucleic acid (DNA) from Mycobacteria. Not only is DNA liberated, but the DNA is suited for subsequent analysis by way of probe hybridization, restriction enzyme analysis, and the like.
