Abstract: A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.

Abstract: Systems and methods for estimating a temperature of an after treatment device in an exhaust system of an engine are described. In one example, the temperature is estimated during condition when an engine exits a fuel cut-out mode and excess fuel is delivered to the after treatment device for the purpose of increasing after treatment device efficiency.

Abstract: A system and method for removing hydrogen sulfide from natural gas using a triazine scavenger is described. The system includes a pre-treatment system that can be connected to an existing hydrogen sulfide removal system to more fully utilize the triazine scavenger. The pre-treatment system includes a contactor vessel in which sour natural gas is contacted with fresh and/or partially consumed scavenger to partially sweeten the sour gas by removing H2S. The partially sweetened gas then flows to the existing hydrogen sulfide removal system where it is fully sweetened.

Abstract: A robot includes a body that is movable relative to a surface one or more measurement devices within the body to output information based on an orientation of the body at an initial location on the surface, and a controller within the body to determine an orientation of the body based on the information and to restrict movement of the body to an area by preventing movement of the body beyond a barrier that is based on the orientation of the body and the initial location.

Abstract: A method of operating an autonomous cleaning robot includes presenting, on a display of a mobile device, a representation of each of multiple cleaning levels, each cleaning level corresponding to a respective rank overlap parameter for a wet cleaning mission of the autonomous cleaning robot. The method includes receiving, at the mobile device, an input indicative of a selection of one of the cleaning levels; and controlling the autonomous cleaning robot to execute a wet cleaning mission according to the rank overlap parameter corresponding to the selected one of the cleaning levels.

Abstract: This disclosure relates to an integrated quantum information processing device with host chips having a body. Each body has a first surface, a second surface opposite the first surface, a defect cluster, and optical structures to direct excitation light that has entered the host chip toward the defect cluster and to direct fluorescent light emitted by the defect cluster to exit the host chip. A base chip has a first side coupled to the second surface of each host chip, a second side, an electromagnetic signal guiding structure to guide electromagnetic control signals toward the defect cluster. A magnetic field is aligned with a spin axis at a colour centre of the defect cluster and enables initialisation and readout of nuclear spin states of the colour centre. For each host chip the defect cluster is located proximate the respective second surface relative to the first surface.
