This application relates to a laptop computer. The laptop computer includes a base portion pivotally coupled to a lid portion is described. The laptop computer includes a display assembly carried by the lid portion, where the display assembly includes a light-transmissive cover, a display layer overlaid by the light-transmissive cover, a display stack electrically coupled to and overlaid by the display layer, and a light pattern recognition module adjacent to the display stack and overlaid by the display layer. The light pattern recognition module includes (i) a light pattern projector that projects a light pattern directly through the display layer.

To detect front-parked vehicles at night (i.e. a vehicle is parked with its head facing the inside of a parking space), a detection device uses the light beam from a passing-by vehicle to extract at least a reflection of at least a tail light or at least a portion of a back bumper from an image captured for a parking space.

A system of identification of items and products is provided, comprising an optical identification mark associated physically and in the database with specific item or product, wherein the optical identification mark comprising an optical element with unique refractive properties and a laser beam source and said optical identification mark configured to transmit the laser beam trough said optical element and surrounding medium to create a light beam with unique light and shape properties which utilized as token for identification of specific optical identification mark and subsequent identification of the associated specific item or product.

Systems, devices, and methods are disclosed for enabling private communication between head-mounted displays. A first user dons a first head-mounted display. The first head-mounted display authenticates that the first user is authorized to view information displayed by the first head-mounted display. In response to positive authentication, the first head-mounted display displays the information to the first user. The first user inputs a selection command via an input interface, such as, for example, gazing at particular information, to select some of the displayed information. The first head-mounted display generates a message based on the user selection, which may be encrypted by the first head-mounted display prior to transmission. The first head-mounted display transmits the message to a second head-mounted display, such that the second head-mounted display displays the message to an eye of a second user wearing the second head-mounted display.

A method of identifying a person by remotely processed data by an identifying party. A person pre-registers a biometric signature with a security service provider. At the time identification authentication is needed, the person is scanned by a camera having a display screen facing the same direction as the camera input lens. The security service provider superimposes optically discernible arbitrarily selected indicia over the image captured by the camera in real time. Imagery captured by the camera, if authentic, will reflect both the digitized characteristic and also the arbitrarily selected indicia for authenticity processing. Authentication is verified if the pre-registered biometric signature matches the biometric signature from the image, and the arbitrarily selected indicia captured in the image matches that provided by the security service provider.

An illumination assembly includes a light source, which is configured to emit optical radiation. A transparency containing a plurality of micro-lenses, which are arranged in a non-uniform pattern and are configured to focus the optical radiation to form, at a focal plane, respective focal spots in the non-uniform pattern. Optics are configured to project the non-uniform pattern of the focal spots from the focal plane onto an object.

A method generates depth maps at a camera having illuminators, a lens assembly, an image sensing element, a processor, and memory. The illuminators operate in a first mode to provide illumination, the lens assembly focuses incident light on the image sensing element, the memory stores programs for execution by the processor, and the processor executes the programs to control operation of the camera. The method reconfigures the illuminators to operate in a second mode, where each of a plurality of subsets of the illuminators provides illumination of a scene separately. For each subset, the process activates the illuminators in the subset without activating illuminators not in the subset and receives reflected illumination from the scene incident on the lens assembly and focused onto the image sensing element. The measured light intensity values of the received reflected illumination at the image sensing element are transmitted to a remote server for processing.

A method for verifying a security document by means of a reading device wherein first transmission and/or reflection properties of a first region of the security document are detected in a first spectral range by the reading device and a first data set specifying these properties is generated therefrom, wherein the first region at least in some regions overlaps an optical security element arranged on the security document or embedded in the security document and wherein second transmission and/or reflection properties of the first region of the security document are detected in a second spectral range by the reading device and a second data set specifying these properties is generated therefrom, wherein the first spectral range differs from the second spectral range, and wherein, the authenticity of the security document and/or of the security element is checked on the basis of at least the first data set and the second data set.

A volume holographic film (such as a photopolymer) that is pre-recorded with patterns subsequently is used to encode LED or low-power laser light reflections from an eye into a binary pattern that can be read at very high speeds by a relatively simple complementary metal-oxide-semiconductor (CMOS) sensor that may be similar to a high framerate, low resolution mouse sensor. The low-resolution mono images from the film are translated into eye poses using, for instance, a look up table that correlates binary patterns to X, Y positions or using a pre-trained convolutional neural network to robustly interpret many variations of the binary patterns for conversion to X, Y positions.

Some embodiments are directed to a biometric authentication system including headwear having a plurality of biosensors each configured to sample muscle activity so as to obtain a respective time-varying signal, a data store for storing a data set representing characteristic muscle activity for one or more users, and a processor configured to process the time-varying signals from the biosensors in dependence on the stored data set so as to determine a correspondence between a time-varying signal and characteristic muscle activity of one of the one or more users, and in dependence on the determined correspondence, authenticate the time-varying signals as being associated with that user.
