Abstract
An example peripheral device to be placed over an image sensor and a light source of a portable computing device to assist the portable computing device in reading a reaction area on a test strip in the peripheral device is disclosed. The peripheral device includes a light guide to direct light from the light source to the test strip, and an alignment feature to aid placement of the peripheral device relative to the image sensor and the light source on the portable computing device.
Claims22
A system comprising:
- a portable computing device;
- and
- a peripheral device to be placed over an image sensor and a portion of a screen on a same side of the portable computing device,
- wherein:
- the portable computing device is configured to read a reaction area on a test strip in the peripheral device and generate an alignment mark on the screen of the portable computing device to indicate where to place the peripheral device on the portable computing device to cover the image sensor and the portion of the screen;
- and
- the peripheral device comprises an alignment feature to aid placement of the peripheral device on the portable computing device and a light guide having a first reflective surface to direct light from the portion of the screen to illuminate the reaction area of the test strip in a manner that the image sensor on the same side is impinged by the light that reflects by the first reflective surface and then passes through the reaction area, by the light that reflects by the first reflective surface and then scatters or reflects from the reaction area, or by the light that reflects from the reaction area and then reflects by the first reflective surface.
A method to guide placement of a peripheral device over an image sensor and a screen of a portable computing device for the portable computing device to analyze a reaction area on a test strip in the peripheral device, comprising:
- generating an alignment mark on the screen of the portable computing device to indicate where to place the peripheral device on the portable computing device to cover the image sensor and a portion of the screen, wherein the image sensor and the screen are on a same side of the portable computing device;
- and
- emitting light with the portion of the screen covered by the peripheral device to illuminate the reaction area after having aligned the peripheral device placed on the portable computing device with the alignment mark.
