An apparatus for detection and quantitation of an electrochemically-detect- able analyte, such as glucose, in blood or interstitial fluid includes a meter unit, a lancet and an electrochemical sensor. Of these components, the meter is preferably reusable, while the lancet and the electrochemical sensor are preferably incorporated in assemblies intended for single-use. The meter unit has a housing, within which a lancet is engaged with a mechanism for moving then lancet; a connector disposed within the housing for engaging an electrochemical sensor specific for the analyte and transmitting a signal indicative of the amount of analyte, and a display operatively-associated with a connector for displaying the amount of the analyte to user. The electrochemical sensor is adapted for detection of a particular analyte. In addition, the electrochemical sensor has an absorptive member for uptake of a sample of blood or interstitial fluid. In one version, the lancet moves from a initial position to a piercing position in which skin of the user is pierced and optionally back to a retracted position. The electrochemical sensor is disposed such that the absorptive member takes up a sample from the pierced skin of the user when it is pierced by the lancet without movement of the apparatus. In an alternative version, the lancet is a hollow cannula through which blood or interstitial fluid is transported from the puncture site to an absorbent portion of the electrochemical sensor. In either version, the apparatus provides single-step operation in which sample acquisition and analysis occur as a result of the single action of pressing the apparatus against the users skin.

An analyte detection system is provided with calibration information uniquely specific to the set of test strips to which the sample is to be applied. The calibration information may be stored in permanent memory of the testing device, such that the device is discarded after use of all the test strips in a kit, or it may be stored in a calibration chip accompanying the set of test strips and distributed therewith, thereby enabling re-use of the testing device with a different set of test strips and associated calibration chip.

A method for testing a ZigBee device included in an IC Card includes associating a predetermined Personal Area Network (PAN) Identifier to the ZigBee device, and providing a test device, for initializing a ZigBee network. The method may include connecting the ZigBee device to the ZigBee network and transmitting the corresponding PAN Identifier to the test device. The method may include returning a fault message, indicative of a failure of connecting and transmitting, if the test device does not receive the PAN Identifier. The predetermined PAN Identifier may be stored in a memory portion of the test device and include, in the fault message, the PAN Identifier if the test device does not receive the PAN Identifier, in order to identify the ZigBee device as a defective device.

A method and apparatus for tracing hardware states using dynamically reconfigurable test circuits provides improved debug and troubleshooting capability for functional logic implemented within field programmable logic arrays (FPGAs). Special test logic configurations may be loaded to enhance the debugging of a system using FPGAs. Registers are used to capture snapshots of internal signals for access by a trace program and a test multiplexer is used to provide real-time output to test pins for use with external test equipment. By retrieving the hardware snapshot information with a trace program running on a system in which the FPGA is used, software and hardware debugging are coordinated, providing a sophisticated model of overall system behavior. Special test circuits are implemented within the test logic configurations to enable detection of various events and errors. Counters are used to capture count values when system processor execution reaches a hardware trace point or when events occur. Comparators are used to detect specific data or address values and event detectors are used to detect particular logic value combinations that occur within the functional logic.

The relative placement of the sample receiving web within the test device is coincident with a portion of each test strip and designed to effect the balanced distribution and delivery of an aliquot of the biologic fluid sample to the test site of each of the test strips within the test device.

A detector and a variable signal generator are coupled so that one or more specific changes in the output of the detector will cause a change in the characteristics of the generated signal. This change in signal characteristics is non-transient, the change remaining in effect until such time that another change in the detector output causes another change in the signal characteristic. The system can provide remote-end positive wire identification with no additional instrumentation at the remote end. When this invention is embodied in an already existing piece of test equipment, such as a multimeter or time domain reflectometer, there need be no additional hardware instrumentation at either end.
