Abstract: A camera module includes a routing substrate, an image sensor, electrical components, molding compound, and an electro-magnetic interference (EMI) shield layer. The routing substrate has a ground plane coupled between a first side of the routing substrate and a second side of the routing substrate. The image sensor is configured to receive incident image light. The electrical components are electrically coupled to the second side of the routing substrate. The molding compound supports the image sensor and supports the electrical components. The EMI shield layer is disposed on the molding compound and the EMI shield layer is tied to the ground plane of the routing substrate.

Abstract: Disclosed herein are techniques for waveguide displays. According to some embodiments, a method for fabricating a multi-layer optical device comprising includes measuring thickness variations within a target area of a first substrate for fabricating a first optical element of the multi-layer optical device and determining, based on the measuring, a thickness correction map indicating amounts of material to be removed in different regions of the target area to planarize the target area. The method also includes planarizing the target area of the first substrate based on the thickness correction map and bonding the first substrate to a second substrate that comprises a second optical element fabricated thereon to form a layer stack, wherein the target area of the first substrate aligns with and is bonded to the second optical element to form a multi-layer structure. The method further includes singulating the multi-layer structure from the layer stack.

Abstract: One embodiment of the present invention sets forth a technique for intelligently accessing one or more different hardware-based mechanisms for cropping out, blurring or blocking private content in a live preview image generated for the camera and in media recorded by the camera. The technique incudes receiving input regarding a plurality of objects to be concealed in media captured by an imaging device and identifying at least one of the plurality of objects in a field of view of the imaging device. Further, the technique includes modifying the at least one of the plurality of objects in a live preview image or media captured by the imaging device using one or more hardware-based actuators, where the modifying the at least one of the plurality of objects causes the one of the plurality of objects to be concealed.

Abstract: A device configured to provide haptic feedback is disclosed. In one embodiment, at least two actuators, at distinct spatial locations, are coupled to a wearable structure configured to be worn on a portion of a user's body. The device is configured to, in response to receiving an indication from a communicatively coupled device, simultaneously actuate the at least two actuators using a first predetermined haptic signal, such that respective haptic responses generated by the at least two actuators are superimposed to generate a combined haptic response having a magnitude greater than the respective haptic responses generated by the at least two actuators.
