Abstract: Example illustrations are directed to a suspension system for a vehicle, which includes a controller configured to determine a roughness of a ground surface associated with the vehicle. The controller may be further configured to determine a height adjustment parameter for the suspension system based on the roughness determined, and to facilitate modification of the suspension system based on the determined height adjustment parameter. Example methods are provided, which may include determining, using a controller, a roughness of a ground surface associated with a vehicle, the roughness determined based on ride height. The method may also include determining, using the controller, a height adjustment parameter for a suspension system of the vehicle based on the roughness determined.

Abstract: Methods and systems are provided for a vehicle suspension system. In some example methods, a height change request is received for a vehicle suspension having a displacement control for implementing height change requests. A displacement of at least one spring of the vehicle suspension may be determined, as well as whether the displacement satisfies a displacement control criteria. The height of the vehicle suspension may be changed using an air mass control in response to determining the displacement control criteria is not satisfied.

Abstract: Example illustrations are directed to a suspension system for a vehicle and methods. In some examples, a controller of a suspension system is configured to determine the vehicle is in a service environment, and to set a height precision mode for the suspension system based on the determination the vehicle is in the service environment. In some examples, the controller is configured to detect a suspension operating condition of the vehicle, and to change a setting associated with the suspension system based on the suspension operating condition. An example method comprises detecting, using a controller, a suspension operating condition of a suspension system of a vehicle. The method may further include changing, using the controller, a setting associated with the suspension system based upon the suspension operating condition.

Abstract: Test access to an integrated circuit 2 is controlled by the use of test access enabling keys. A plurality of different test access enabling levels may be supported corresponding to different keys. The test access control may be performed by dedicated hardware or software executing a secure privilege mode.

Abstract: A running/setting tool for packers is disclosed which can release in several different ways. The tool can be pumped through for normal release. The tool may be hydraulically released by dropping and pumping a ball to a seat and subsequent pressurizing. A frangible member is provided so that if circulation is impeded, it can be established by breaking the frangible member to allow a ball to be pumped to a seat. Finally, a shear release technique is provided which allows release by breaking a shear pin or shear ring or other frangible member, which unsupports collets to allow for removal. A support shoulder is provided on the tool to prevent the collets from becoming stressed on the trip out of the hole if the tool encounters a collar or other internal obstruction.

Abstract: Sewage flows through an inflow pipe into a receiver. Large solids are trapped in the receiver, and dissolved and suspended materials pass with the waste water through apertures in the receiver wall. A lower portion of the receiver has a solid wall to trap fine heavy grits. The receiver is held suspended from a lower opening in an upward opening holder. When the receiver is full of solids, waste water flows through larger apertures in the holder. A cover of the holder is removed, and the receiver is withdrawn through an upper opening in the holder by a handle which extends from the receiver to the upward opening. One holder and receiver are mounted directly within a closed self-contained underground tank. Several tanks are coupled in parallel or series. The tanks are provided with aeration devices in a main portion and have a partition which forms a chlorifying portion with a sludge return at the bottom of the partition and a skimmer return at the top of the partition.
