Abstract: The light communication solution presented herein uses waveguides with multiple entrances to efficiently collect light used for light communications and propagate that collected light to a sensor. To that end each waveguide entrance, or at least all but the initial waveguide entrance, is configured to not only collect and input the light into the TIR waveguide, but also to maintain TIR of light already propagating within the TIR waveguide. In so doing, the solution presented herein increases the amount of light available for light communications. Further, because each waveguide may channel light from multiple collection points to a single sensor, the solution presented herein reduces the number of sensors needed for the light communications. The solution presented herein facilitates the implementation of light communications for a wide variety of devices (e.g., cellular telephones, tablets, smartphones, smart watches, smart glasses, etc.) and/or in a wide variety of scenarios.

Abstract: A detection system for light communications comprises a total internal reflection (TIR) waveguide and a light sensor adjacent to the TIR waveguide. The TIR waveguide comprises a TIR structure, a diffusive element, and a waveguide entrance. The TIR structure is configured to internally propagate light associated with optical signaling along the TIR waveguide. The diffusive element is disposed at an internal edge of the TIR structure opposite the light sensor. The diffusive element is configured to disrupt the propagation of the light such that at least some of the light is directed to the light sensor. The waveguide entrance is offset from the diffusive element along the TIR structure and configured to collect the light into the TIR structure.

Abstract: A method of waking up a mesh node in a wireless mesh network, wherein said mesh node comprises a main receiver and a wakeup receiver, and wherein said method comprises the steps of receiving, by said wakeup receiver of said mesh node, a wake up signal message, wherein said wake up signal message comprises context information which is related to a path between a source mesh node and a destination mesh node corresponding to said wake up signal message, determining, by said wakeup receiver of said mesh node, that said context information is applicable for said mesh node, activating, by said wakeup receiver of said mesh node, said main receiver of said mesh node for subsequently receiving a data message.

Abstract: Devices implementing light communications use waveguides to efficiently collect light used for the light communications and propagate that collected light to a sensor. More particularly, light collected from one or more sensors propagates along a TIR waveguide until disrupted by a diffusive element, which effectively directs the propagating light to a sensor. In so doing, the solution presented herein increases the amount of light available for the light communications and/or reduces the number of sensors needed for the light communications, e.g., by providing light collected from multiple different locations to a single sensor. The waveguide solution presented herein may be implemented inside a device and/or along an exterior surface, e.g., housing or casing, of a device.

Abstract: In a web browser (100) access is controlled with respect to at least one user data providing device (102), the web browser comprising a browser engine (106), a browser application (104) and a device access proxy, DAP (108). Access is acquired, in the DAP, to at least one user data providing device and a request is received from a web application (110) for user data from a first user data providing device. In response to the request, default data (112) is transmitted from the DAP to the web application. A user data access confirmation signal is obtained, and in response to the user data access confirmation signal, the transmission of the default data is discontinued and the requested user data is transmitted from the DAP to the web application.

Abstract: A system and method for providing a location-based service from a third party service provider includes encrypting a client's identification information using a public key exchanged with a network location server, wherein the network location server stores a record indicating a location associated with the identification information. The encrypted identification information is transmitted from the client to the third party service provider. The third party service provider transmits a location request to the network location server, the location request including the encrypted identification information received from the client. The third party service provider provides the location-based service according to a response to the location request from the network location server.
