    摘要： A digital “baton” is provided from a firewall or other gateway, or other network device, to a device B outside the firewall, when a device A, which is inside the firewall, requests information from the device B. The device B may pass the digital baton to subsequent electronic devices that may respond to the request using the digital baton to send messages or information through the firewall to the device A. The firewall authenticates and filters the messages based on authentication of the batons contained within the messages.

    摘要： A line powered data access arrangement (DAA) is disclosed which adaptively allows proper operation with power supplied from a telephone line as conditions warrant, while at the same time satisfying the relevant requirements of many countries. In the line powered codec, a startup procedure for the international line powered codec uses register settings, e.g., country-specific register settings, which are powered and maintained from the low voltage side (e.g., from the PC or modem side) of the line powered codec. In this way, even during low line power conditions the programmed state of the line powered codec can be maintained, thus a default condition will not necessarily returned to by the line powered codec upon reset due to a power loss in the telephone line. In another aspect, a charge storage device such as a charge capacitor is charged from a charge pump formed from a differential clock signal from the low voltage side. A current and voltage detection module in the line powered codec is always powered from the telephone line. Upon detection of an off-hook signal or a power down condition, the current detection module determines if/when the current and voltage on the telephone line is sufficient to power certain circuits on the line powered codec. If sufficient power is not present, the line powered codec does not power up. However, the line powered codec will power up if sufficient current is detected. In another aspect, a plurality of power rails may be provided. A first power rail may be associated with the line power, a second power rail may be associated with a low voltage side power source, e.g., a charge storage device. A third (and other) power rails may be switchably connected to either the first power rail or second power rail as line power conditions and on-hook/off-hook conditions warrant.

    摘要： The use of a precipitable dye and a contrast-coloring dye together enhance visualization of plaques in confluent lawns of bacteria in bacteriophage and bacteria assays. A test sample suspected of containing a bacteriophage is combined with bacteria capable of replicating the bacteriophage, and applied to a water-proof surface to form a support for bacterial growth. The support is provided with the contrast-coloring dye and precipitable dye, and nutrients and salts capable of supporting growth of the bacteria. A lawn of bacteria is formed on the support, and plaques detected on the lawn indicate presence of the bacteriophage. The plaques contain a precipitate formed by enzymatic cleavage of the precipitable dye by an enzyme of the bacterial lawn. A similar procedure is used for detecting bacteria, except that a test sample suspected of containing a bacteria is combined with bacteriophage capable of replicating in the bacteria, and plaques detected indicate presence of the bacteria. The bacteriophage and bacteria assays are carried out with a disposable device containing at least one well having a water-proof surface and a depth of about at least 5 millimeters. A hydratable material containing the contrast-coloring dye and precipitable dye is positioned on the surface. The well may contain substantially vertical sides with a removable cover resting on top of the sides.

    摘要： Bacteria are detected in a test sample by contacting the test sample with a bacteriophage that is capable of replicating in the bacteria, adding the resultant sample to a water-proof surface of a support for bacterial growth that contains a contrast-coloring dye and a precipitable dye, forming a bacterial lawn of a bacteria in which the bacteriophage can replicate on the support and detecting plaques on the bacterial lawn as an indication of the presence of the bacteria. The combination of precipitable dye and contrast-coloring dye improves visualization of plaques. A precipitate is formed in plaques by enzymatic cleavage of the precipitable dye by an enzyme of the bacterial lawn. A procedure for detecting bacteriophage is similar to that for detecting bacteria, except that a test sample suspected of containing bacteriophage is combined with bacteria in which the bacteriophage can replicate, and plaques detected indicate presence of the bacteriophage. The bacteria and bacteriophage detections are carried out with a disposable device containing at least one well having a water-proof surface and substantially vertical sides that extend at least 5 millimeters in height from the surface. A hydratable material containing the precipitable dye and the contrast-coloring dye is positioned on the water-proof surface. A removable cover rests on top of the sides of the well.
