  • Patent number: 11659033
    Abstract: A technique to cache content securely within edge network environments, even within portions of that network that might be considered less secure than what a customer desires, while still providing the acceleration and off-loading benefits of the edge network. The approach ensures that customer confidential data (whether content, keys, etc.) are not exposed either in transit or at rest. In this approach, only encrypted copies of the customer's content objects are maintained within the portion of the edge network, but without any need to manage the encryption keys. To take full advantage of the secure content caching technique, preferably the encrypted content (or portions thereof) are pre-positioned within the edge network portion to improve performance of secure content delivery from the environment.

  • Patent number: 11614806
    Abstract: Self-mixing interferometry (SMI) sensors can be used for generation of content using an input device without requiring a touch-sensitive surface. In some examples, the SMI sensors can be used to detect characteristics of the input device including position, orientation, and/or motion of the input device and/or force applied by the input device (e.g., force applied by a stylus tip). In some examples, some or all of the characteristics of the input device can be used in processing to generate content, including textual character input and three-dimensional objects. In some examples, the generation of content can use information from one or more additional sensors for the input device and/or from additional devices in combination with the characteristics of the input device based on the SMI sensors for generation of content.

  • Publication number: 20230089141
    Abstract: Self-mixing interferometry (SMI) sensors may include vertical cavity surface emitting lasers (VCSEL), photodetectors, and microelectromechanical systems (MEMS). The VCSEL, photodetectors, and MEMS may be vertically stacked. The MEMS may be moveable with respect to a VCSEL and may change a cavity length associated with the VCSEL. By changing the cavity length associated with the VCSEL, certain properties of emitted light may be changed, such as a wavelength value of the emitted light.

  • Publication number: 20230087411
    Abstract: An electronic device may include an infrared sensor with light sources and a quantum film photodetector. The light sources may emit short-wavelength infrared (SWIR) light through a display panel and the photodetector may receive the SWIR light through the panel after reflection off an object. The light sources and an integrated circuit may be mounted to a wall of a sensor module mounted to the panel. The module may include a lens. The photodetector may be disposed onto the rear wall, lens, integrated circuit, or display panel. The photodetector may include multiple types of quantum film to absorb different wavelengths of SWIR light. The SWIR light may pass through the display panel without distorting images emitted by the display panel. Using a quantum film in the photodetector may allow the photodetector to extend across a large surface area without unnecessarily increasing manufacturing cost for the device.

  • Publication number: 20230070943
    Abstract: Configurations for a beam deflector metasurface are disclosed. The beam deflector metasurface may include beam deflectors arranged in a repeating, radial pattern of concentric zones. The beam deflector metasurface may be a large area, high numerical aperture metasurface optic with high efficiency when directing light at non-normal angles of incidence. The different concentric zones may direct received light in varying directions with various steepness of angles. The beam deflectors may include pillars that may be the same or different width, height, or shape. The pillars may function as diffractive gratings and the cross-coupling between the pillars may direct the output light. The zones of the beam deflector metasurface may allow for diffusing hot spots and spreading the light evenly over the target area. The beam deflector metasurface may be used for non-imaging applications where the deterioration of focus allows for better efficiency at non-normal input and output angles of incidence.

  • Patent number: 11599224
    Abstract: Disclosed herein are electronic devices having touch input surfaces. A user's touch input or press on the touch input surface is detected using a set of lasers, such as vertical-cavity surface-emitting lasers (VCSELs) that emit beams of light toward the touch input surface. The user's touch causes changes in the self-mixing interference within the VCSEL of the emitted light with reflected light, such as from the touch input surface. Deflection and movement (e.g., drag motion) of the user's touch is determined from detected changes in the VCSELs' operation due to the self-mixing interference.
