Electronic Devices With Optical Identification Sensor - A simplified explanation of the abstract
This abstract first appeared for US patent application 18446228 titled 'Electronic Devices With Optical Identification Sensor
Simplified Explanation
- The patent application describes an electronic device that can be attached to an external item. - The device includes an optical identification sensor that can detect a color-encoded tag on the external item when it is attached to the device. - The optical identification sensor consists of multiple layers, including a board layer, a protective filter layer, and wall structures for support. - A linear array of photodetectors is placed between the board layer and the protective filter layer. - A field-of-view restriction filter is placed between the photodetectors and the protective filter layer. - The device also includes a light source with multiple emitters that can illuminate the color-encoded tag. - The emitters are activated one by one to capture multiple images, which are then combined to accurately read the color-encoded tag. - This reading can be used to identify the type of external item that is currently attached to the electronic device.
Original Abstract Submitted
An electronic device may be attached to an external item. The electronic device may include an optical identification sensor configured to sense a color-encoded tag in the external item when the item is attached to the device. The optical identification sensor may include a board layer, a protective filter layer, wall structures for supporting the protective filter layer on the board layer, a linear array of photodetectors disposed between the board layer and the protective filter layer, a field-of-view restriction filter interposed between the photodetectors and the protective filter layer, and a light source having multiple emitters for illuminating the color-encoded tag. The emitters may be activated sequentially to produce multiple images that are combined to reconstruct an accurate reading of the color-encoded tag, which can then be used to identify the type of external item currently attached to the electronic device.
