Abstract: A system is provided for automatically adjusting the air pressure of a tire based on variations in loading to improve tread wear. For a particular loading of the tire, the system provides for the determination of a preferred air pressure setting designed to minimize tread wear. This preferred air pressure, Pp, is determined from an analysis of the longitudinal stresses that occur within the contact patch of the tread.

Abstract: Methods, apparatuses, systems, and devices are described for redundancy management for a storage system including a plurality of storage devices. Approaches for redundancy management may involve storage device failure prediction techniques and/or a redundancy value associated with a data file. In one example, a copy of the file may be stored on at least two storage devices. Whether or not to store an additional copy of the file on another storage device may be based at least in part on the redundancy value for the file. In another example, a determination may be made whether to store a copy of the file on another storage device when a storage device storing a copy of the file is predicted to fail. Whether to store a copy of the file on another storage device may be based at least in part on a redundancy value associated with the file.

Abstract: An electric machine comprises a motor housing and an electronics enclosure coupled to the motor housing. The electronics enclosure defines an air passage between the electronics enclosure and the motor housing. The electronics enclosure further defines at least one air intake connected to said air passage. The electric machine also includes a fan configured to draw air through the at least one air intake and into the air passage.

Abstract: A tire work stand comprises a frame for supporting the work stand on a ground surface and for attaching a set of components to the tire work stand. A plurality of rollers is attached to the frame to support a tire above the ground surface and to permit rotation of a tire during inspection of the tire. A ramp is configured to have a first ramp end capable of extending from the ground surface and a second ramp end extending to a position proximal to the frame. A bridge is configured to have a first bridge end extending from the second ramp end and a second bridge end extending to a position proximal to a surface of at least one of the rollers, wherein the bridge acts to inhibit rotation of the roller during loading of the tire and further permits rotation of the tire after the tire has been loaded on the tire work stand.

Abstract: A method for adjusting the camber of a vehicle's axle comprising attaching collars to the axle of the vehicle attaching links to the collars, introducing a deflection in the axle in a concave downward direction and modifying the length of the links.

Abstract: Methods and systems are provided for acquiring seismic data. An ambient electromagnetic signal having a known time dependence is transmitted for propagation within a survey area. The ambient electromagnetic signal is received at distinct geographic locations with independently operating data acquisition units positioned at the distinct locations. Data representing acoustic signals received from the Earth at the distinct geographic locations are collected with the data acquisition units. The collected acoustic signals for the distinct geographic locations are synchronized by correlating the known time dependence of the propagated electromagnetic signal with time dependencies of the collected acoustic signals.

Abstract: A method of estimating the airspeed of an aircraft during low airspeed conditions includes measuring a negative impact pressure using a pitot-static probe on the aircraft. Then, the method includes estimating a non-zero airspeed of the aircraft as a function of the measured negative impact pressure.
