Patents by Inventor Lawrence Stanley Silver

Lawrence Stanley Silver 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: 6372511
    Abstract: Swabbing structures and methods of use are provided that enable a test surface to be swabbed, and subsequently facilitate a quantitative determination of the quantities of analyte collected from the test surface. The swabbing structures include a pre-wetted swabbing pad having a first surface structured for contacting and suitably swabbing the test surface to collect the analyte. Dried reagents are then brought into pressure contact with the swabbing pad, within a light-tight environment, to commence an assaying reaction. The assaying reaction may produce low level luminescent emissions that are detected and quantified to indicate the quantity or volume of analyte collected.
    Type: Grant

  • Patent number: 6328931
    Abstract: Swabbing and assaying structures, and selected methods of use, enable a test surface to be swabbed, and subsequently facilitate a quantitative determination of the quantities of analyte collected from the test surface. The swabbing structures include a pre-wetted swabbing pad having a first surface for contacting and suitably swabbing the test surface to collect the analyte. Dried reagents that are impregnated within or upon a porous pad are then brought into pressure contact with the swabbing pad, within a suitable light-tight environment. If sufficient analyte was collected by the swabbing of the test surface, an assaying reaction will commence that produces detectable and quantifiable low level luminescent emissions.

  • Patent number: 6197254
    Abstract: A self-contained and highly portable assaying system includes a luminometer and a detector cap assembly. The detector cap assembly, which is structured with a first portion and a second portion, is capable of collecting a specimen, and causing a bioluminescent or chemiluminescent assaying reaction to be conducted in a light-tight environment within the detector cap assembly (devoid of any available ambient light). The luminometer is structured to be removably fixed to the detector cap assembly to sense low level luminescent emissions produced by the assaying reaction. A quantified result is subsequently provided to a user or operator that indicates the outcome of the assay activities.
