Abstract: A calibration device for a turbidimeter is disclosed. The calibration device includes a body made from a light-permeable material having a first end and a second end defining a length. The calibration device further includes at least one calibration portion defined by a first aperture having a light scattering pattern. The first aperture is oriented perpendicular to the first end, and the first aperture extends into the body a first distance that is less than the length of the body. The turbidimeter is calibrated by inserting one of the at least one calibration portion of the calibration device into the sensing region.

Abstract: A single management facility in a virtualized system that facilitates the presentation of either a virtual element view or system view to a network management user depending upon the user's access rights is disclosed. The user interface presented to the user is modified based on the scope and type of access rights. The scope and type of access privileges afforded to the user of the virtualized system is found in a profile object that indicates the scope and type of user access established during the user login. The profile object is stored in an environment object that is created for each user at login. Each virtualized element in the system includes management information that is associated with the virtual element via a virtual identifier. The management information indicates the level of the user access privileges necessary to view the associated virtual element.

Abstract: A single management facility in a virtualized system that facilitates the presentation of either a virtual element view or system view to a network management user depending upon the user's access rights is disclosed. The view presented to the user is modified based on the scope and type of access rights, which are found in a profile object, that is stored in an environmental object, established during the user login. Each virtualized element in the system includes management information that is associated with the virtual element via a virtual identifier. The management information indicates the level of the user access rights necessary to view the associated virtual element. Requests by a user to access management information associated with a virtual element are analyzed to determine if the access rights specified in the user profile enable the user to access the information associated with the virtual element.

Abstract: A damper assembly, comprising: a support means defining a plurality of (air) openings; damper means mounted or connected to the support means in relation to the openings for the periodic closure and opening of such openings; a crankshaft means coupled to the damper means such that rotation of the crankshaft means is able to induce displacement of the damper positions to respective second damper positions and back to the first position for adjusting air flow through said openings.

Abstract: A utility vehicle equipped with a steering and suspension system wherein the direction pivot point is centered and positioned as close as possible to the pivot point of the suspension, and the assembly point of the wheel pivot is centered, to significantly reduce the effect of uneven ground surface, which causes the wheels to turn to the left or to the right when rolling up a bump or rolling down a crevasse. The suspension system provides complete independence for each wheel.
