This application claims priority under 35 USC 119 to Provisional Patent Application No 60 478 436 filed on Jun 12 2003 entitled Method and Apparatus for Providing Power Management in Data Communication Systems the disclosure of which is incorporated herein by reference for all purposes BACKGROUND The present invention relates to data monitoring systems More specifically the present invention relates to portable analyte monitoring systems More specifically the present invention relates to a compact blood glucose meter for use in a glucose monitoring system to self monitor glucose level in whole blood as an aid to disease management and also by healthcare professionals as an aid to monitor the effectiveness of diabetes treatment SUMMARY OF THE INVENTION The market for glucose monitoring systems in the United States as well as globally is rapidly increasing as better health education and early detection of diabetic conditions through regular check ups have increased the percentage of the dia betic population who undertake the task of monitoring their diet and daily activities based on the detected level of blood glucose using glucose monitoring systems One group of such rapidly increasing segment of the population is children with diabetic conditions who are advised to monitor their blood glucose levels While miniaturization has been a factor of recent designs in the glucose monitoring systems and the glucose meters
4. the physical constraints of the components of such systems have established a certain size limitation As such the larger and bulkier the device the less desirable and convenient for the device to be carried around or used and operated by the patients especially children In view of the foregoing in accordance with the various embodiments of the present invention there is provided a blood glucose meter which is designed to be substantially more compact than presently available commercial blood glucose meters which configuration that is much more ame nable to usage and portage by younger diabetic patients such as children More specifically in one aspect of the invention the blood glucose meter is configured to include a LCD backlight and a flashlight features which will assist the patient in reading the metered glucose level in low light testing areas such as in theaters low ambient light restaurants areas outdoors during non daylight times and so on as well as a light source to guide the insertion and removal of the test strip which may include the usage of a light emitting diode Indeed as the light source e g the LED may be pulsed and still display substantially the same light output as one which is turned on in steady state the battery life ofthe glucose meter device may be prolonged since the pulsed LED light source requires significantly less power and thus draining the battery at a much slower rate than when the LED l
