Abstract: According to the present invention, there is provided a method and device for the viewing, editing and dissemination of an editable object in real-time mobile collaboration sessions. The invention comprises a set of mobile terminals and a protocol which enables users to simultaneously edit the same editable object. An advantageous embodiment of this invention allows for synchronization to occur in real time. Further, synchronization and version control problems are avoided as the invention considers each user's edited version to be a genuine version of the data. The end result of the editing process may be several different versions, and not just one single authoritative version.

Abstract: An apparatus for quantifying irradiance has a first sensor having an output for providing a reference signal of irradiance within a first band, such as the visible light band. A filter and a second sensor are in optical series so that irradiance sensed at the second sensor is filtered. The second sensor outputs a filtered signal of irradiance within the first band. The filter particularly filters irradiance in the first band as a function of irradiance in the second band, such as the UV light band. In an exemplary embodiment, the filter is made from a material that darkens with increasing UV irradiance. A processor has inputs coupled to the outputs of the first and second sensors for determining irradiance in the second band from the reference signal and the filtered signal. Mathematical formulations for the processor are provided, as are methods and a computer program embodied on a medium. A single sensor embodiment is also described.

Abstract: The specification and drawings present a new method, apparatus and software product for optical focusing and stabilizing using a hydraulic component, called focusing stabilizer, in an image focusing module of the electronic devices. This focusing stabilizer is capable of doing focus adjustment and/or image stabilization. The focusing stabilizer can comprise two optical elements (e.g., two plates or prisms, two lenses, or one plate or prism and one lens) and a liquid between them. The refractive index and thickness of the liquid changes a length of the optical path from the object to the photosensitive surface such that the system focus shift depends on a liquid lens thickness in the direction of the optical axis. In addition, adjusting two optical components using a predetermined criterion provides a stabilization of the focused image.

Abstract: The invention relates to a method of creating an image file in an imaging device and an imaging device comprising at least two image capturing apparatus, each apparatus being arranged to produce an image. The apparatus is configured to utilize at least a portion of the images produced with different image capturing apparatus with each other to produce an image with an enhanced image quality.

Abstract: The invention relates to a method, server and device arrangement for transmitting high-class multimedia messages of a mass event. When this method is utilized, the data transfer capacity of the cell of a cellular network serving the participants of the mass event need not be increased so that it would correspond to the capacity of the multimedia messages to be transmitted. In a method according to the invention, the cell that serves the mass event mainly transmits only text messages by which the multimedia messages to be sent from a multimedia server to some other terminal devices are defined.

Abstract: A method for managing a memory 22 of an electronic device 20 within which user files Fi are stored includes storing a new user file Fi in the memory 22; discovering 46 that an unused memory portion 24 is less than a preset threshold; prioritizing 48 the stored user files Fi; selecting 50 the user file Fi with the highest priority; and compressing 52 the selected user file Fi. The amount of unused memory 24 (now expanded) is again compared 54 to the threshold, and if unused memory 24 is lacking, the user files Fi are again ordered 48, and the highest priority user file Fi, which may or may not be the same as the last iteration, is selected 50 and compressed 52. The algorithm continues until the amount of unused memory 24 equals or exceeds the threshold. An electronic device 20 for practicing the method is also disclosed.

Abstract: The invention relates to a focusing method for a camera and camera where the lens system (10) is attached in a fixed manner to the body (14) of the camera at a fixed distance from the photosensitive surface (12) of the camera. Rays of light (S) coming from a target to be photographed are focused onto the photosensitive surface by placing between the lens system (10) and photosensitive surface one or more focusing plate(s) (16) made of a material that lets light pass through and the both surfaces of which are flat. The focusing plate is made of a material the index of refraction of which is greater than one, whereby rays of light will be refracted at the surfaces of the plate as they travel through the focusing plate. Refraction of the rays of light changes their course of propagation, which makes it possible to focus the camera to different ranges.
