20120083044 | ELECTRONIC ANALYTE ASSAYING DEVICE - An improved electronic diagnostic device for detecting the presence of an analyte in a fluid sample comprises a casing having a display, a test strip mounted in the casing, a processor mounted in the casing, and a first sensor mounted in the casing and operatively coupled to the processor. The processor is configured to receive a signal from the first sensor when the device is exposed to ambient light thereby causing the device to become activated. The device includes a light shield that exerts pressure across a width of the test strip to prevent fluid channeling along the length of the test strip. The processor is configured to present an early positive test result reading when a measured value exceeds a predetermined early reading threshold value at any time after a predetermined early testing time period. | 04-05-2012 |
20130040401 | TEST STRIP READER - In one innovative aspect, systems and methods for modular electronic test kits such that test can be more easily fabricated as well as integrated with other devices is provided. In a further innovative aspect, systems, and methods for test strip readers including improved accuracy of the tests performed by the test reader are provided. | 02-14-2013 |
20130065321 | SYSTEMS, METHODS, AND TEST KITS FOR ANALYTE VARIATION DETECTION - Systems, methods, and test kits for monitoring and detecting variation in an analyte level in a fluid sample from an individual variation using a uniquely determined analyte threshold value. In one implementation, luteinizing hormone is the monitored analyte and is compared with the determined threshold value to predict the onset of ovulation for the individual. | 03-14-2013 |
20130217136 | DEVICES, METHODS, AND TEST KITS FOR ELECTRONIC ANALYTE ASSAYING - An improved qualitative or semi-quantitative diagnostic test for low levels of any analyte, such as hCG, in a biological sample, such as urine. The test comprises of a test device containing reagents for the detection of the monitored analyte and an electronic reader that measures color development at a detection area of the device. The color development is converted to an electronic or digital signal. Improvements were made to the detection process to optimize the detection of a valid fluid front, increase the detection limit without compromising the reliability and accuracy of the test system, and improve the determination of test result validity. | 08-22-2013 |
20150017068 | IMPROVED ELECTRONIC ANALYTE ASSAYING DEVICE - An improved electronic diagnostic device for detecting the presence of an analyte in a fluid sample comprises a casing having a display, a test strip mounted in the casing, a processor mounted in the casing, and a first sensor mounted in the casing and operatively coupled to the processor.
