摘要:
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.

A system, a computer program product and a method of characterizing a cellular telecommunications network area are disclosed. The method comprises: receiving (606) measurement data characterizing measured cell quality of a plurality of radio cells in a plurality of spatiotemporal coordinate points; selecting (608) a plurality of sub-areas within a cellular telecommunications network area, each sub-area confining a plurality of spatiotemporal coordinate points; calculating (610) sub-area cell quality parameters of radio cells, each sub-area cell quality parameter representing cell quality of a radio cell within a sub-area and being calculated by combining measurement data within the sub-area; and generating (612) a cell preference list for at least a portion of the cellular telecommunications network area on the basis of the sub-area cell quality parameters.

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.

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.
