Abstract: A method of distinguishing a control solution from a sample in an electrochemical test sensor is performed. The method includes adding a control marker to the control solution. The control solution includes the control marker and analyte. The test sensor includes working and counter electrodes, and a reagent. A potential is applied to the test sensor to oxidize the control marker and the analyte. The resulting electrical current is measured. A potential is applied to the test sensor lower than the other potential in which the potential is sufficient to oxidize the analyte and not the control marker. The resulting electrical current is measured. Determining whether a control solution or a sample is present based on the measured electrical currents. To increase the measured current, a salt may be added to the control solution in an amount sufficient to increase the electrical current by at least 5% as compared to a control solution in the absence of a salt.

Abstract: The present invention provides biosensor test devices for measuring the presence or amount of an analyte in a biological fluid. The devices have a base plate that has an electrode system embedded therein, and a hydrophilic porous material situated on the base plate. A hydrophobic protective layer is situated on the hydrophilic porous material, and a cover is placed on the hydrophobic protective layer to complete the device. Some embodiments also use an insulating layer, which can be situated between the base layer and the hydrophilic porous material. The cover of the device has an opening present therein, situated over the electrodes, so that the electrodes communicate with the exterior of the device through the groove. The insulating layer can also have a groove situated therein, which in one embodiment is placed to align with the groove in the cover. The invention also provides methods of manufacturing the devices, and methods of using them.

Abstract: A testing system for testing an analyte in a fluid sample includes a user interface including a display for displaying information relating to measurements of health data and an input device for receiving information from a user relating to the health data. The testing system further includes an automarking feature adapted to identify a testing result of a control solution, the testing of the control solution being distinguishable from the testing of the fluid sample. The testing result of the control solution is not included in the information relating to the measurements of health data that is displayed to a user via the user interface.

Abstract: A cleaning assembly for a pipe. The assembly comprises a sleeve, at least one magnet, and at least one moveable hollow member. The sleeve is moveably disposed on the outer wall of the pipe. The at least one magnet is disposed on the inner surface of the sleeve. The at least one moveable hollow member conforms to the profile of the pipe's interior and is disposed in the interior of the pipe and is metal. When an external force acts on the sleeve along the longitudinal axis of the pipe, the at least one moveable hollow member moves with the sleeve by means of magnetic attraction to clean condensed powder from the pipe.
