    摘要: A true random number generator comprises a ring oscillator which is triggered to start oscillating in a first mode of oscillation at an oscillation start time. The first mode of oscillation will eventually collapse to a second mode of oscillation dependent on thermal noise. A collapse time from the oscillation start time to the time at which the oscillator collapses to the second mode is measured, and this can be used to determine a random number. The TRNG can be synthesized entirely using standard digital techniques and is able to provide high randomness, good throughput and energy efficiency.

    摘要: A method for controlling fluid flow in an assay device that employs a membrane is provided. Specifically, one or more recessed regions are formed in the membrane by applying a solvent treatment thereto. The solvent treatment is selected based on its particular dissolving capacity for the material used to form the membrane. For example, an alcohol-based solvent, such as methanol, may be used as a solvent for nitrocellulose membranes. Upon contact with the solvent treatment, a recessed region is formed that may serve a variety of different functions relating to flow control. In one particular embodiment, the recessed region may function as a metering channel that is capable of delivering a controlled volume of the test sample to a detection zone upon initiation of the assay.

    摘要: An edge-stiffened sheet material probe is provided. The probe is useful for probing and cleaning of small, constricted or confined spaces. For example, the probe may be suitably used as a dental probe for cleaning interdental spaces. The probe formed from at least one fibrous web material that is cut and sealed to form an edge and terminates at a first point. In addition, the probe may be formed from or as a laminate of two or more fibrous web material layers that are cut and sealed, or may be formed from or as a laminate of the at least one sheet or material may be folded or two or more sheets may be cut and sealed to form. A pack of connected probes is also provided.

    摘要: There is provided a lateral flow assay device for detecting the presence or quantity of an analyte residing in a test sample where the lateral flow assay device has a porous membrane in communication with a wicking pad. The porous membrane has a detection zone which has a chromophore configured to chemically react with an analyte or a secondary trigger or a reaction product from the analyte and a trigger generating reagent(s), to generate a visually detectible signal. Additional chrmophore zones may be located downstream from the first chrmophore zone to generate signals of varying color. Scavenging zones may be included between chromophore zones to attenuate the signal by reacting with the analyte without generating a visually detectable signal.
