Abstract: A lawnmower including: a wheel; a motor operably coupled to drive the wheel; a user input configured to receive a steering control input from a user; and a controller configured to operate in a steering assist mode where the controller: receives information from the user input, the information including a position of the user input; compares the position of the user input to a gain profile saved in a memory of the controller; determines a scale factor from the gain profile based on the comparison; generates a command instruction to control a speed of the motor based on the position of the user input and the determined scale factor; and transmits the command instruction to the motor to affect a speed of the motor.

Abstract: In combination with video content transmitted by a video streaming service, additional content may also be displayed to viewers. The video streaming service may provide a framework that allows the additional content to be provided by third parties. By allowing third parties to develop and provide additional content, the range of interactions and experiences made available through such content may, in some cases, be significantly expanded. The additional content may be displayed inside a respective assigned area, such as an inline frame (Iframe), embedded within a web page or other interface in which the video content is displayed. Additionally, techniques may be provided for controlling focus between a video player that displays the video content and the embedded area that displays the additional content, for example to help ensure that user input is provided to its intended target.

Abstract: A cross linkable composition includes a copolymer part being composed of a copolymer of ethylene and an organic acid salt of an alkyl, alkenyl, or alkynyl radical including 26% to 42% by weight of monomer, representing 50% to 90% by weight of the polymer phase; and an acrylonitrile-butadiene copolymer having 25% to 50% by weight acrylonitrile, representing 10% to 50% by weight of the polymer phase. It further has carbon black having a specific surface area of less than 170 m2/g, representing 40% to 75% by weight of the polymer phase and additives such as antioxidants, anti-coppers, peroxides, silanes, in quantities that generally remain below 5% of the polymer phase.

Abstract: A maintenance-free open industrial storage battery includes an electrode assembly comprising at least one positive electrode, one negative electrode, one separator disposed between the negative electrode and the positive electrode, an alkaline electrolyte covering the top end of the assembly before electrical cycling and a valve the relative operating pressure of which is less than 1 bar. The total capacity of the negative electrodes is greater than the total capacity of the positive electrodes. The separator is permeable to oxygen and the storage battery contains an oxygen recombination device such that after at least one cycle of charging and discharging the storage battery operates without loss of electrolyte at a charging current at least equal to Ic/10 where Ic is the current discharging the capacity of the storage battery in one hour.

Abstract: An electrochemical cell has an alkaline electrolyte comprising a stack placed in a container and composed of at least one anode and at least one cathode containing nickel hydroxide. An oxygen recombination system has at least one recombination electrode which is at least partially hydrophobic and has two opposite faces of large surface area. A first face is joined to the anode. The cell is characterized in that the recombination electrode is associated with a rigid structure which forms, in contact with the second face of the electrode, a nonreducible volume space of small width so as to allow oxygen access throughout the duration of use of the cell.
