Abstract: The disclosed technology teaches a method of identifying roles to coalesce. The disclosed role coalescence engine includes compiling roles from an enterprise database and associated role features respective to each role (such as members who belong to a particular role or access privileges assigned to a particular role), computing a similarity measure between pairs of roles with respect to a single role feature, and clustering role pairs based on the similarity measure. The method further includes generating a cluster visualization based on the clustered role pairs and causing display of the cluster visualization to a user with controls for selecting a particular cluster of the cluster visualization. Coalescence of role databases results in improved security for identity governance and administration tools by reducing unauthorized or inappropriate access.

Abstract: A system and method of adjusting a field of view in an imaging system includes transmitting light across a transmission optical path and defining a field of view encompassing both uniform and spatially tenuous target objects within the transmitted light. A sensor within a return optical path of reflected light from at least a portion of one of the target objects allows a data processing computer to compile an image from a series of data outputs from the sensor. The image is analyzed to determine a region of interest within the image and by dynamically adjusting the light source, the computer is configured to change the field of view of the light source such that the image includes a higher resolution and/or signal intensity for the region of interest. The region of interest may include at least one spatially tenuous target object.

Abstract: A backpack blower has a backpack with a load-bearing frame, a blower tube with a backpack-side tube section which is held on a rear side of the load-bearing frame, and a hand-side tube section which extends past a first side region of the load-bearing frame, a drive motor, an energy source for the drive motor, and an axial fan which is driven by the drive motor, has an axial fan axis, and is arranged in the backpack-side tube section of the blower tube. The backpack-side tube section of the blower tube runs with a main direction component in a backpack transverse direction of the load-bearing frame and has an axial blower tube end termination which projects laterally beyond a second side region of the load-bearing frame, which second side region faces away from the first side region, and/or is surrounded at least on a part of its circumference by a protective ring element which is connected to the load-bearing frame. The blower may be an electric leaf blower.

Abstract: The disclosure relates to an electric blower apparatus having a blower spiral which has a first axial end wall, a second axial end wall and a blower air outlet. An electric motor which drives a fan wheel rotating in the blower spiral is held on the first axial end wall, the fan wheel inducting ambient air by way of an intake opening in the second axial end wall. A cover element, the cover surface thereof being configured so as to be larger than the air inlet surface of the intake opening, is disposed in front of the intake opening. To induct a large quantity of ambient air with little noise, it is provided that the cover element is configured as a cover plate, wherein an annular gap which forms the intake channel for the direct access of ambient air is configured between the plate edge and the blower spiral.

Abstract: A power tool has a drive unit and an operating handle. At least one electrical line connects the operating handle and the drive unit to each other. The at least one electrical line is fastened at a first electrical connection location to the operating handle and at a second electrical connection location to the drive unit. A safety cable extends along the at least one electrical line between operating handle and drive unit. The safety cable has a first end section and a second end section. The first end section is connected mechanically fixed at a first fixation location to the operating handle. The second end section is connected mechanically fixed at a second fixation location to the drive unit. The at least one electrical line and the safety cable are guided together such that the safety cable forms a tear-off protection for the at least one electrical line.
