A device which supports identification of an integrated display and dynamic adjustments to operating parameters thereof includes: a port that receive a test strip having a reaction site for receiving a sample of fluid from a patient, a blood glucose (bG) meter cooperatively operable with a test strip inserted in the port to measure glucose in a sample of fluid on the test strip, and a display device having an electrically resistive component integrated therein and operable to display the glucose measurement in accordance with one or more operating parameters associated with the display device The system also includes a monitoring module electrically connected to the resistive component, wherein the monitoring module determines a type for the display device based on a resistance of the resistive component and a control module that selectively adjusts a given operating parameter of the display device in accordance with the type of display device.

System and method for display type detection of a handheld medical device

A portable handheld medical diagnostic device includes a front housing and a rear housing opposite the front housing. The front housing and the rear housing form a protective enclosure. A main circuit board is located in the protective enclosure. The main circuit board includes a controller facilitating a physiologic measurement. A display device is connected to the main circuit board that displays information related to the physiologic measurement. A frame is located in the protective enclosure that carries the display device and locates the display device adjacent the front housing such that the display device can be viewed from outside the protective enclosure. The frame includes a strip port formed integrally therewith that is accessible from outside the protective enclosure.

A medical device and a method for displaying medical data by the medical device are disclosed. In one aspect of the disclosure, a method for displaying medical data by a medical device having a display device and one or more processors is disclosed. The method includes monitoring a condition of the display device and determining, at the medical device, whether the display device is in a failure state based on the monitoring, the failure state being indicative of a malfunction of the display device. When the display device is a failure state, the method includes commanding a slave device to display the medical data and providing the medical data from the medical device to the slave device for display by the mobile device.

Method for displaying medical data by a medical device during display failure

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.

A portable handheld medical diagnostic device includes a housing forming a protective enclosure. A main circuit board is located in the protective enclosure. The main circuit board includes a controller facilitating a physiologic measurement. A display device is connected to the main circuit board that displays information related to the physiologic measurement. An electronic skin is on the housing. The electronic skin comprises a liquid crystal material and is configured to display a color.

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.
