Patents by Inventor Mark Diggs

Mark Diggs 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: 9251381
    Abstract: A solid-state storage subsystem, such as a non-volatile memory card or drive, includes a main memory area that is accessible via standard memory access commands (such as ATA commands), and a restricted memory area that is accessible only via one or more non-standard commands. The restricted memory area stores information used to control access to, and/or use of, information stored in the main memory area. As one example, the restricted area may store one or more identifiers, such as a unique subsystem identifier, needed to decrypt an executable or data file stored in the main memory area. A host software component is configured to retrieve the information from the subsystem's restricted memory area, and to use the information to control access to and/or use of the information in the main memory area.

  • Patent number: 7608240
    Abstract: The present invention provides a novel approach to cancer therapy and diagnostics that utilizes nanotubes and other similar nanostructures as both an indirect source of radiation therapy (BNCT), and as delivery vehicles for other types of radio- and chemo-therapeutic materials, as well as imaging agents for diagnostic purposes.

  • Publication number: 20070269814
    Abstract: A method of determining the presence and level of microorganisms and/or chemicals in samples taken from generally any non-laboratory substance or environment. The method preferably comprises one or a combination of the steps of (a) prescreening for threshold levels of targeted microorganisms and/or (b) confirming the presence of targeted microorganisms or chemicals by mass spectrometry fingerprint analysis.

  • Publication number: 20070260811
    Abstract: A non-volatile solid-state storage subsystem, such as a non-volatile memory device, maintains usage statistics reflective of the wear state, and thus the remaining useful life, of the subsystem's memory array. A host system reads the usage statistics information, or data derived therefrom, from the subsystem to evaluate the subsystem's remaining life expectancy. The host system may use this information for various purposes, such as to (a) display or report information regarding the remaining life of the subsystem; (b) adjust the frequency with which data is written to the subsystem; and/or (c) select the type(s) of data written to the subsystem.
