re DEVICE AND METHOD FOR PRODUCING FUEL EFFICIENT CANDLES CONFIGURED WITH HELICAL WICKS By www.freepatentsonline.com Published On :: Thu, 27 Apr 2017 08:00:00 EDT Helical wick candle and method of manufacturing this candle. The candle typically comprises a candle with meltable fuel such as wax, and at least one helical wick with a helical radius of at least ¼″ or greater. This helical wick is configured so that as the candle burns, the burning tip of the wick doesn't remain stationary, but rather circles the axis of the wick so as to burn more of the wax than would otherwise be possible with a prior art straight wick candle, at least when the diameter of the candle is larger than the pool of melted wax surrounding the wick. This results in higher fuel burning efficiency, often 1.5× or higher, as well as various interesting artistic shapes as the wick burns. Various wick sheath methods to improve the rigidity and burn resistance of the wick during the burning process are also discussed. Full Article

re PREDICTION OF COMPONENT MAINTENANCE By www.freepatentsonline.com Published On :: Thu, 13 Apr 2017 08:00:00 EDT One or more processors determine wear for a robotic device. The one or more processors divide a direction of travel of a robotic device into zones. Each zone has an associated counter that counts how many times the robotic device has entered a given zone. The one or more processors update a count for a zone in response to the robotic device entering that zone. The one or more processors determine a level of wear for a component associated with the robotic device. The level of wear is based, at least in part, on a total of counts for the zones. Full Article
re OPTICAL MEDIUM REPRODUCTION APPARATUS AND OPTICAL MEDIUM REPRODUCTION METHOD By www.freepatentsonline.com Published On :: Thu, 27 Apr 2017 08:00:00 EDT The present disclosure relates to a reproduction apparatus. The reproduction apparatus may comprise an optical filter and electric filters. The optical filter may be configured to provide electrical signals corresponding to regions of an optical beam returning from an optical medium, the optical beam being incident on the optical filter, the regions of the optical beam corresponding to different bands in a line density direction and/or a track density direction. The electric filters may be configured to provide outputs based, at least in part, on the electrical signals provided by the optical filter, wherein the reproduction apparatus is configured to obtain a reproduced signal by combining the outputs of the electric filters.

re ENCODING, DISTRIBUTION AND REPRODUCTION OF AUDIO MEDIA USING MECHANICAL IMAGE DIGITIZATION By www.freepatentsonline.com Published On :: Thu, 04 May 2017 08:00:00 EDT The system and corresponding process includes a system for producing a mechanical image of original audio source media and a system for encoding the mechanical image information into a digital file. A processing system recovers the mechanical image information from the digital file at a receiving end. Audio processing is used to produce the original audio source material without the standard losses associated with digital encoding of audio material Full Article
re OPTICAL MEDIUM REPRODUCTION DEVICE AND OPTICAL MEDIUM REPRODUCTION METHOD By www.freepatentsonline.com Published On :: Thu, 11 May 2017 08:00:00 EDT An optical medium reproduction device includes: a detection unit configured to form detection signals of respective channels by dividing a cross-section of a beam returning from the optical medium into a plurality of regions and performing division into at least one channel corresponding to the region at an outer side in a radial direction, at least one channel corresponding to the region that is different in position in a tangential direction, and a channel corresponding to the other regions, and, in a case of forming the detection signals of the channels, form the detection signal of at least one of the channels by weighting and adding a signal in a predetermined region among the plurality of regions; a multi-input equalizer unit configured to include a plurality of equalizer units to which the respective detection signals of the plurality of channels are supplied, and configured to form an equalized signal on the basis of the detection signals of the plurality of channels; and a binarization unit configured to perform a binarization process on the equalized signal to obtain binary data.
