By a News Reporter-Staff News Editor at Electronics Newsweekly -- Maxim Integrated Products, Inc. (San Jose, CA) has been issued patent number 9472696, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.
The patent's inventors are Kerness, Nicole D. (Menlo Park, CA); Samoilov, Arkadii V. (Saratoga, CA); Wang, Zhihai (Sunnyvale, CA); Jones, Joy T. (Fremont, CA).
This patent was filed on August 11, 2014 and was published online on October 18, 2016.
From the background information supplied by the inventors, news correspondents obtained the following quote: "Electronic devices, such as smart phones, tablet computers, digital media players, and so forth, increasingly employ light sensors to control the manipulation of a variety of functions provided by the device. For example, light sensors are commonly used by electronic devices to detect ambient lighting conditions in order to control the brightness of the device's display screen. Typical light sensors employ photodetectors such as photodiodes, phototransistors, or the like, which convert received light into an electrical signal (e.g., a current or voltage).
"Light sensors are commonly used in gesture sensing devices. Gesture sensing devices enable the detection of physical movement (e.g., 'gestures') without the user actually touching the device within which the gesture sensing device resides. The detected movements can be subsequently used as input commands for the device. In implementations, the electronic device is programmed to recognize distinct non-contact hand motions, such as left-to-right, right-to-left, up-to-down, down-to-up, in-to-out, out-to-in, and so forth. Gesture sensing devices have found popular use in handheld electronic devices, such as tablet computing devices and smart phones, as well as other portable electronic devices, such as laptop computers, video game consoles, and so forth."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "A light sensor is described that includes an IR suppression filter (e.g., any type IR interference based filter) and at least one photodetector integrated on-chip (i.e., integrated on the die of the light sensor) with a transparent substrate. In one or more implementations, the light sensor comprises a semiconductor device (e.g., a die) that includes a semiconductor substrate. Photodetectors (e.g., photodiodes, phototransistors, etc.) are formed in the substrate proximate to the surface of the substrate. A IR suppression filter is positioned over the photodetectors. The IR suppression filter is configured to filter infrared light from light incident on the light sensor to at least substantially block infrared light from reaching the photodetectors. A buffer layer is formed over the surface of the substrate. In an implementation, a transparent substrate is coupled to the IR suppression filter to provide support to the IR suppression filter. In another implementation, the transparent substrate may be attached to the wafer (e.g., substrate wafer) with another buffer (e.g., adhesion) layer. In yet another implementation, the IR suppression filter may be positioned over the surface of the substrate so that the buffer layer is between the glass wafer and the substrate wafer. The photodetectors may also comprise one or more clear photodetectors configured to detect the ambient light environment.
"This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter."
