Introduction

Darren Edward Noel Wenn is a notable inventor based in High Wycombe, GB. He has made significant contributions to the field of technology, particularly in the development of medical devices. With a total of 2 patents to his name, his work focuses on improving the accuracy and efficiency of glucose measurement and temperature sensing.

Latest Patents

One of his latest patents is titled "Glucose measurement using a current source." This innovative blood glucose meter includes a blood sample test strip, a constant current source, a precision timer, a digital processor, memory, and an analog measurement circuit. This design eliminates the complex analog front end and other related circuits found in current glucose meters. When a blood sample is applied to the test strip, a charge, Q, develops from the reaction between an enzyme in the test strip and the blood sample. The constant current source injects a constant current value, I, into the charge, Q, over a precisely measured time. The amount of charge is determined by the equation Q=I*T, and this charge is then converted into a blood glucose level for display.

Another significant patent is for "High resolution temperature measurement." In this invention, temperature is determined by measuring the time it takes to charge a capacitor with a resistive temperature sensor. A clock, time counter, voltage comparator, and voltage reference are utilized to determine a coarse time measurement. The resolution of this time measurement is enhanced by adding a constant current source that charges another timing capacitor within a single clock pulse time, providing a fine time measurement.
