Abstract: A wearable device with a display screen has both an image presentation area and a camera portion. The wearable device includes a camera module configured to capture images through the camera portion and a camera frame that is molded onto the display screen, creating a pocket in which the camera module is securely held. This camera frame is made of a material that not only keeps the camera module in place but also forms an environmental seal, effectively protecting the space between the camera module and the display screen.

Abstract: A light field display is composed of a light source assembly (LSA), a collimating lens, an incoupling section, a spatial light modulator (SLM), and gratings. The LSA includes point light sources that emit light at different time periods. The collimating lens collimates light from the point light sources. The incoupling section incouples the collimated light to a waveguide. The SLM spatially modulates the collimated light. The gratings outcouple spatially modulated light from the waveguide, and for any given point light source of the point light sources, the given point light source has a respective corresponding grating of the gratings that outcouples from the waveguide light that originated from the given point light source. The spatially modulated light output in each time period forms a respective virtual emitter in an eyebox, and over the different time periods the virtual emitters in aggregate form at least one virtual object.

Abstract: According to examples, a wearable device may include an imaging component, at least one wireless communication component, and a controller. The controller may activate the at least one wireless communication component to perform a wireless scan of at least one radio available to respond to the wireless scan. The controller may also receive, through the at least one wireless communication component, wireless scan data from the at least one radio and may embed the wireless scan data as part of a media metadata. The wireless scan data may be used to determine a location estimate of the at least one radio and thus, the wearable device. The location estimate of the wearable device may also be used to geotag media captured by the wearable device without using a GPS receiver on the wearable device or when a GPS receiver is unable to track a current location.

Abstract: An organic field effect transistor includes a channel structure having a photoalignment layer and an organic semiconductor layer disposed directly over the photoalignment layer, where a charge carrier mobility varies along a thickness direction of the channel structure. The channel structure may define an active area between a source and a drain of the transistor and may include alternating layers of at least two photoalignment layers and at least two organic semiconductor layers. Each photoalignment layer is configured to influence an orientation of molecules within an overlying organic semiconductor layer and hence impact the mobility of charge carriers within the device active area while also advantageously decreasing the OFF current of the device.
