Abstract: Electronic reading devices provide readers with text on a display, and enhancements to their functionality and efficiency are discussed herein. Text is provided to the reader in an enhanced contrast mode that highlights the active word and line of the text as well as words of interest in the text so as to improve the functionality of the electronic reading device itself as a provider of textual content.

Abstract: An image of an eye is obtained via a camera. A multi-step filter is applied to the image for multiple iterations. Applying the multi-step filter includes, for each iteration, performing one or more pixel merge operations on the image. The pixel merge operations are controlled based on one or more input parameters to control whether or not the iteration classifies pixels of the image as corresponding to a feature of the eye. The one or more input parameters vary from at least one iteration to another. The iterations each output a provisional output, in which some pixels of the image are deemed as corresponding to the feature of the eye. The provisional outputs provide diverse definitions of the eye feature, and may be combined in various ways to yield a refined output, in which some pixels of the image are deemed as corresponding to the feature of the eye.

Abstract: Disclosed herein is a fracturing unit for hydraulic fracturing having an engine and a fracturing pump connected to the engine through a variable speed torque converter. Also disclosed is a hydraulic fracturing system using multiple fracturing units which are sized similar to ISO containers. A hydraulic fracturing system may also force flow back water, produced water, or fresh water through a heat exchanger so that heat from the fracturing engines can be transferred to these liquids in order to vaporize them. A force cooled fractioning unit then can accept the vapor/steam in order to condense the various components and produce distilled water for re-use in the fracturing process or for release into the environment.

Abstract: A display system comprises a display and a controller operatively coupled to the display. The controller is configured to receive text, parse the text to isolate a segment of the text, compute a time interval for display of the segment, present the segment on the display during the computed time interval, remove the segment from the display following the computed time interval, and repeat the parsing computing, presenting, and removing, for subsequent segments of the text.

Abstract: A method and system for matching digital information flow to the human perception system. In various embodiments, multi-monitor (multimon) support is leveraged to take advantage of multiple windowing and window positioning to separate elements of different tasks into information planes (which are based on a concept of “triage and focus”). Triage watches the flow of incoming information and determines the nature of the information. Based on the nature of the information and principles of human perception, Focus (or defocus) displays the information where the information is best viewed.

In particular, the invention relates to the production of impact copolymers using reactor systems including a plurality of multi-zone circulating reactors.

Abstract: A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and an elongate shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween.

Abstract: A ladder hoist attachment consists of a boom and prop combination that allows a conventional ladder to be used to hoist heavy loads. The boom assembly consists of a number of feet that removably attach to a rung of the ladder; a boom that extends horizontally over the top rung of the ladder; and braces connecting the feet and boom that also rest against the top rung of the ladder. One end of the prop removably attaches to a lower rung of the ladder. The other end of the prop has a vertical step to hold the ladder at a predetermined distance away from the edge of the roof. A winch or pulley is suspended from the end of the boom extending over the top rung of the ladder to allow loads to be lifted through the prop and between the ladder and the building. After the load has been lifted above the height of the roof, the end of the prop against the building is lifted by the user to allow the ladder to be moved to rest against the edge of the roof, thus allowing the load to be lowered on to the roof.
