Abstract: A blood glucose test device with viewing lens seal includes a meter body rigid portion of a first polymeric material and an opening. A resilient portion of a second polymeric material more compressible than the first polymeric material integrally connected to the rigid portion defines a rigid portion outer covering. A resilient portion edge extends beyond the rigid portion and partially into the opening about a perimeter of the opening. A transparent polymeric material lens has an outer perimeter surface in contact with the resilient portion edge. Multiple flexible arms extending from the lens each have a hook member. Each hook member engages a receiving member positioned in a meter body and is retained by multiple backup ribs. Hook member engagement at a locking position pulls the lens toward the edge partially compressing the second polymeric material and creating a fluid seal between the perimeter surface and edge.

Abstract: A limited-use blood glucose meter includes a printed circuit board assembly that includes a power source, a strip port, a strip reading device, a controller device, a bi-stable display, and a display controller. The strip reading measures a reaction between a blood sample present on the blood glucose test strip and the blood glucose reagent, generates a blood glucose signal, and calculates a blood glucose level. The controller device receives the blood glucose level from the strip reading device. The controller device provides display instructions to the display controller and the display controller provides drive voltages to the bi-stable segments such that the bi-stable segments persistently display the most-recent blood glucose level. The strip reading device performs a predetermined number of blood glucose tests and calculates a blood glucose level only for blood glucose strips associated with the disposable blood glucose meter.

Abstract: A test and measurement instrument according to an embodiment of the present invention provides a disparity cursor for making quick and easy disparity measurements. In operation, a user uses a sample cursor to specify a pixel of a first image and uses the disparity cursor to specify a pixel of a second image. The test and measurement instrument then automatically provides a measured disparity value based on the two pixels.

Abstract: A control circuit and method for controlling a bi-stable display having bi-stable segments each capable of transitioning between an on state and an off state via application of a voltage are disclosed. The voltage is provided to a display driver from a charge pump, and supplied to individual ones of the bi-stable segments via outputs from the display driver in accordance with display instructions provided by a system controller. Both a bi-stable segment voltage level of at least one of the outputs of the display driver and a charge pump voltage level of the voltage are detected and compared to a valid bi-stable segment voltage level and a valid charge pump voltage level, respectively. A malfunction signal may be provided to the system controller if either of the detected voltage levels is not valid. The control circuit is useful in an electronic device such as, for example, a blood glucose measuring device.

Abstract: A blood glucose monitoring system with a graphical user interface (GUI) and methods of controlling the system and performing episodic blood glucose testing using the GUI are disclosed. The system can comprise the GUI, an output display for displaying the GUI, user interfaces, a memory and a processor. An episodic blood glucose testing protocol can be programmed into the processor using the user interfaces and automatically saved into memory. A user can be alerted to test blood glucose levels based on the inputted testing protocol by the display of an alert icon on the GUI. Blood glucose level results can be received, displayed on the GUI along with a range icon and automatically saved into memory. Statistics of the saved blood glucose results can be calculated by the processor and saved into memory. The statistics can be retrieved for display on the GUI when prompted by the user.

A boron nitride filled adhesive is used to bond the support to the base and bond the helix wire to the base. The boron nitride filled adhesive is also used to bond the base to the ground plane. Heat generated in the helix wire is transferred to the ground plane via the base.

Abstract: Methods for adhering polyimide dielectric materials to copper-, titanium-, aluminum-, or copper-and-titanium-containing portions of a substrate are described. The methods include the steps of applying adhesion promoter to a clean surface of the substrate, and curing the adhesion promoter. SPIE varnish is applied over the cured adhesion promoter, and is itself cured. A further layer of adhesion promoter is applied over the cured SPIE varnish, and is cured. The polyimide dielectric material is then laminated to the adhesion promoter. Cleaning of the copper-containing substrate portions is performed by etching with etchant including cupric chloride, cleaning of the titanium-containing substrate portions is performed with etchant including HF, and cleaning of copper- and titanium-containing portions is performed by HF etching followed by cupric chloride etching. Aluminum-containing portions of the substrate are not etched.
