Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: A tool and method examine error report information from a computer to determine not only whether a virus or other malware may be present on the computer but also may determine what vulnerability a particular exploit was attempting to use to subvert security mechanism to install the virus. A system monitor may collect both error reports and information about the error report, such as geographic location, hardware configuration, and software/operating system version information to build a profile of the spread of an attack and to be able to issue notifications related to increased data collection for errors, including crashes related to suspected services under attack.
