Abstract: The present invention discloses a novel method for the production of metallic nano-powder. This cost-effective, simple process is customized for a full-scale production of metallic nano-powders containing a first metal, and comprising the following of forming an alloy comprising said first metal and at least one soluble metal; applying first thermal treatment in the manner homogenized alloy is obtained; applying a cold work to the homogenized alloy so thin strips are obtained; applying a second thermal treatment to the alloy until a phase composition of predetermined characteristics is obtained; subjecting the said alloy to a leaching agent adapted to effectively leach out the least one soluble metal; filtering and washing the powder; washing the powder; drying the powder; coating the powder with chemicals; and then de-agglomerating the coated powder. The present invention also discloses a cost-effective and highly pure metallic powder produced by the method defined above.

Abstract: A sensor includes a light detector for dividing light in an environment into optical zones and detecting light from the optical zones. The sensor also includes a processor coupled to the light detector; and a memory coupled to the processor for storing the detected light as historic light readings.

Abstract: An embodiment generally relates to a method of operating a sensor array. The method includes adjusting the reverse bias voltage for the photodiode of at least one pixel in the sensor array based on previous output values of one or more pixels in the array, algorithms, and/or user inputs.

Abstract: A display includes a backlight comprising light sources. The light sources are divided into sections. The display also includes a transmissive display panel positioned adjacent to the backlight, a diffuser positioned between the backlight and the transmissive display panel, and a control circuit coupled to the backlight and the transmissive display panel. The control circuit synchronizes light output by the backlight with a transmittance of the transmissive display panel.

Abstract: A method of extending color depth in a display includes determining pixel sub-intervals for pixel intervals in a video signal, modulating a transmissivity of a display panel of the display from one sub-interval to another sub-interval, and modulating backlight intensity of a backlight from the one sub-interval to the another sub-interval.

Abstract: To effective increase the dynamic range of a pixel array, a plurality of brightness groups is set. The pixels of a pixel array are then distributed among the groups according with their likely brightness. Each image frame is scanned in the order of brightness, with the pixels in the group likely to be the brightest being scanned first and the pixels in the group likely to be the darkest being scanned last. The brightness groups are adjusted at the boundary of the frame scan.

Abstract: A novel method for enhancing the surface area of bulk metals is hereto presented. The method comprising according to one embodiment the steps of dispersing metal nano particles in a solution comprising water-soluble polymeric materials; introducing the a cathode substrate inside the dispersed solution; and than applying electric current to this cathode, so it is coated by said highly dispersed nano particles. According to yet another embodiment the method comprising the steps of coating bulk metals with nano particles made of a predetermined metal alloy; and than chemically leaching at least one of the metals such as a very high surface area of said coated metal is obtained. The present invention also presents bulk metals e.g., electrodes, coated by means of the methods defined above.
