Abstract: Embodiments include processes for media object rendering, including the steps of providing a plurality of clients, the clients including a media client and the clients in communication with a synchronization client, the clients defining a synchronization group. The media clients include instructions for receiving media object content over a network from a content server, rendering the media object content, and random access to the media object content in response to synchronization client seek time instructions. The synchronization client includes instructions to calculate a relative lag and provide seek time instructions to the media clients for a media object being rendered, the relative lag being a running measurement of its offset relative to the synchronization server's clock. The synchronization client periodically queries the clock of a synchronization server.

Abstract: The invention relates to a photosensitive printing composition comprising a photocatalyst which exhibits a photocatalytic effect when exposed to UV and/or visible radiation, a colouring agent that exhibits a colour change in response to the photocatalytic effect, and a film forming agent. The composition has a viscosity suitable for printing. The invention further relates to a sun-exposure sensor comprising a photosensitive layer printed on a surface of a support, the photosensitive layer comprising a photocatalyst which exhibits a photocatalytic effect when exposed to UV and/or visible radiation, a colouring agent that exhibits a colour change in response to the photocatalytic effect, and a film forming agent.

Abstract: A system and method for allowing users of wireless and mobile devices to participate in Public Key Infrastructure facilitates secure remote communications. The present invention allows wireless devices to participate in secure communications with secure networks without storing compromisable information on the wireless device. In one embodiment, the system allows wireless devices to participate in Public Key Infrastructure wherein no portion of the certificate, no information about the certificate, and no private or public key data are stored on the wireless device. In one embodiment, a certificate proxy server maintains the digital certificate and private for the client device in a secure fashion, and maintains connectivity with the wireless network. The mobile user can authenticate with the server in order to access resources that require the certificate to be presented.
