  • Patent number: 5755231
    Abstract: A test strip includes a first layer and an overlying differential flow-retarding layer that reduces the fraction of a component of a liquid specimen percolated therethrough. An inert backing, preferably having an aperture therethrough, overlies the flow-retarding layer. For the testing of a blood specimen, the flow-retarding layer is formed of glass fibers that reduce the fraction of red blood cells in the percolate, leaving primarily, but not entirely, plasma in the percolate. The first layer includes chemicals that react with a component of the plasma such as glucose in a measurable reaction, preferably a visually measurable reaction. In using this test strip, the blood specimen is placed into the aperture of the backing and permitted to percolate through the flow-retarding layer such that a fraction of the red blood cells is removed from the percolate.

  • Patent number: 5715422
    Abstract: A data-storage and processing card has a data-storage memory and a read/write memory. Data processing instructions are stored in the data-storage memory, along with the data. The data processing instructions require memory storage capacity for their execution, and the read/write memory is selected to be sufficiently large to meet this processing storage capacity requirement. To process the data, the card is plugged into a host computer, whose central processing unit recalls and executes the processing instructions. The read/write memory of the card is utilized as the required memory storage capacity for the processing. Alternatively, the card may include a central processing unit that processes the instructions. The card is particularly useful for storage of data compressed form and decompressing the data with data decompression processing instructions.
