Abstract
Embodiments described are generally directed to a test sample apparatus. The test sample apparatus generally comprises a holder base arranged that accommodates a tablet or cell phone. The apparatus has a hood that is placed over a portion of the tablets illuminating touchscreen such that the illuminating touchscreen provides light that can be collected by the hood. There is a chamber integrated with the hood adapted to accommodate a chemically activated test strip. The chemically activated test strip is illuminated when the hood collects light from the illuminating touchscreen. A lens in the hood interposed between the camera and the test strip enables the camera to focus on a portion of the chemically activated test strip when the hood is placed over the portion of the illuminating touchscreen.
Claims19
A test sample apparatus operably used with a handheld electronic device, the handheld electronic device possessing a front surface having an illuminating screen and a camera, the handheld electronic device further possessing a top, two sides and a bottom, the camera lens is closer to the top than the bottom, the test sample apparatus comprising:
- an illumination chamber adapted to cover a portion less than the entirety of the illuminating screen, the illumination chamber configured to overlay a camera lens, the illumination chamber further configured to collect light from the illuminating screen while the illuminating screen is activated, the illumination chamber configured to attenuate a significant portion of ambient light sources originating outside of the electronic device, the illumination chamber possessing a slot adapted to receive the top of the handheld electronic device in a sliding relationship;
- a top chamber integrated with the illumination chamber, the top chamber providing a test device holder slot adapted to accommodate a test device holder, the test device holder arranged to hold a test device, the illumination chamber and the top chamber collectively provide a pathway configured to bias the light source to favor collected light originating from the illuminating screen to the test device while concomitantly attenuating the ambient light sources originating outside of the light path between the illuminating screen and the test device, the pathway also configured to provide the camera with a view of the test device.
A method comprising:
- providing a handheld electronic device possessing a front surface having an illuminating screen and a camera;
- placing a test device in a chamber integrated with a light collecting hood, the light collecting hood adapted to significantly block ambient light originating from other than the illuminating screen;
- positioning the light collecting hood over the camera and a portion of the illuminating screen that when positioned inherently provides a pathway between the camera and the test device;
- illuminating the test device from light produced by illuminating the screen;
- capturing an image of the illuminated test device with the camera in real-time while the test device is developing or after the test device is developed;
- and
- post processing of the camera-captured image of the test device.
A test sample apparatus operably used with a handheld electronic device, the handheld electronic device possessing a front surface having an illuminating screen and a camera, the handheld electronic device further possessing a back surface, a top, two sides and a bottom, the camera is closer to the top than the bottom, the test sample apparatus comprising:
- an illumination chamber adapted to cover a portion less than the entirety of the illuminating screen, the illumination chamber configured to overlay the camera lens, the illumination chamber further configured to collect light from the illuminating screen while the illuminating screen is activated;
- a top chamber integrated with the illumination chamber, the top chamber providing a test device holder slot adapted to accommodate a test device holder, the test device holder arranged to hold at least one test device, the illumination chamber and the top chamber collectively provide a pathway configured to funnel the collected light from the illuminating screen to the test device, the pathway also configured to provide the camera with a view of the test device.
