  • Plasma sample collection device
    Patent number: 8453525
    Abstract: A plasma sample collection device includes an elongated blood separation strip having a constant width and a relatively narrower end portion. A support base is located under the plasma separator strip and a cover is positioned superincumbent with respect to the blood separator strip. The cover defines an elongated observation window extending along the length of the plasma separator strip. An oblong collection port is adjacent to but spaced from one end of the observation window. The oblong collection port exposes the separator strip end portion and has a chief axis substantially aligned with the longitudinal axis of the blood separation strip. In one embodiment, the collection port has a teardrop configuration, and in another embodiment it has an obovate-cuneate configuration.

  • Signal level indicator and associated method
    Patent number: 5486843
    Abstract: A signal level indicator (204, 304) displays the magnitude of an input signal (421) by illuminating each of a number of five LEDs (314-318, 414-418) for an individual period of time. The number of LEDs to be illuminated and the individual period of time that each is to be illuminated varies with the magnitude of the input signal (421).
