Title: Video processing
Inventor: NIGEL JOHN WILLIAMS
IPC: H04N5/20
Filed: 2020-07-29
Abstract: Image processing of video images, suitable for a head-mounted device (HMD), detects whether input image brightness at image locations in a preceding input video image exceed a threshold 1720. If so, a relationship between display properties 1730 at a given image location in a given output video image to those 1700 in the corresponding input video image is varied. The given image location may represent the same image location in the given output video image and in the one or more preceding input video images. A gaze detector may detect a gaze direction for each eye of the wearer of the HMD. The given image location for an image may represent an image location pointed to by the gaze direction detected for that image. The image processor may decrease a ratio between the display brightness 1740 at the given image location in the given output image and the input image brightness at the given image location in the corresponding input video image with respect to time to simulate a decline in the sensitivity of the vision of the wearer of the HMD. The image processor may display a representation of image content as an after image by varying colour balance.

Title: Lighting device
Inventor: SIMON WHITE
IPC: H01L33/50
Filed: 2020-09-30
Abstract: A lighting device adapted to enhance the visibility of objects to the human eye in scotopic and mesopic lighting conditions comprises a first light source 7 adapted to emit light at a wavelength shorter than that which induces the peak photopic human eye response. This is also adapted to emit light to illuminate an object simultaneously with a second light source 9 adapted to emit light in a broad bandwidth within the photopic span.

Title: Systems and methods for implementing occlusion representations over road features
Inventor: GIANCARLO BALDAN
IPC: G06K9/00
Filed: 2021-01-05
Abstract: A vehicle (e.g., an autonomous vehicle) is configured to address occlusion and visibility uncertainty over critical road features (e.g., stop sign areas, intersections, travelled/adjacent lanes, or crosswalks) for safe decision making. A perception module of the vehicle provides occlusion information in areas of interest 1504 (e.g., precedence areas such as incoming cross traffic lane areas or stop areas such as stop sign areas nearby the vehicle) to a planning module of the vehicle 1508. Instead of providing full occlusion data (e.g., 2D or 3D data) from dense occlusion maps, the perception module provides an efficient representation of the occlusion information by assigning respective levels of occlusion to a series of coarsely partitioned segments in the areas of interest (e.g., segmentation of incoming lanes along traffic flow direction) 1506. Moreover, the perception module updates the occlusion information by temporal filtering to further increase visibility of the planning module. The perception module can also periodically update the occlusion information for the vehicle selectively within the current areas of interest, e.g., based on a current route from the planning module.

The audio interface device further comprises an interface 112 configured to communicate the normalised signal with an external device 60. The audio interface device may enter a safe setting on power-up, wherein the attenuation is set to maximum and the gain is set to minimum. The interface device may also include transformer or opto-coupled isolation between the audio line input and the digital side of the interface device, allowing wiretap connection to ‘100 volt’ speaker lines. Several devices may be daisy-chained (fig.5).

Title: Method and system for secure transfer of confidential data
Inventor: DENYS RTVELIASHVILI
IPC: H04L9/40
Filed: 2021-04-16
Abstract: One or more shared secrets are established, between a provider of confidential data and a consumer, by performing key agreement communications (eg Diffie-Hellman) over communication paths S101. Symmetric keys are derived from the shared secrets S102, and used by the provider to encrypt the confidential data S103 which is then transferred to the consumer S104, using a different communication path to those used for key agreement. The provider may establish initial communication using an initially-known address for the consumer, and may then obtain an additional address of the consumer for communication between the provider and consumer. The consumer may comprise an outer layer, which communicates with the provider and an inner layer (fig. 3), which implements cryptographic operations of the consumer (key agreement and decryption) but does not communicate directly with the provider. In such embodiments the outer layer cannot access the decrypted data.

Title: Spatial rendering of reverberation
Inventor: ANTTI ERONEN
IPC: G10L19/008
Filed: 2022-03-02
Abstract: Spatial rendering of a virtual scene in an acoustic environment 205 is assisted by obtaining a reverberation parameter and converting this into frequency band data (eg. a range and number of octave bands), then encoding both. The resources (eg. bitrate or channel capacity) required to transmit the encoded parameter and data are compared and used to generate a bitstream comprising the reverberation parameter (in eg. a high bitrate mode), the frequency band data (in eg. a low bitrate mode), or both, along with an environment identifier and information defining environmental dimensions. The transmitted bitstream is then decoded and the reverberator (eg. a Feedback Delay Network reverberator) initialised.
