Abstract: A method for determining state of health of a battery on a vehicle comprises identifying a SOH testing segment on which the battery can be charged at a known charging rate for a time duration and determining an increase in voltage based on the charging rate, the time duration, an internal resistance of the battery, and/or a battery temperature differential over the time duration.

Abstract: A telepresence system and method for aligning a remote pan and tilt system with the position of a user's head and for displaying to the user a first portion of the field of capture of the remote pan and tilt system. The pan and tilt system moves to track the movement of the user's head. When the pan and tilt system is in a misaligned position with the position of the user's head the image displayed to the user is a second portion of the field of capture of the remote pan and tilt system.

Abstract: A telepresence system and method is disclosed for aligning a remote pan and tilt system with the position of a user's head and for displaying to the user a first portion of the field of capture of the remote pan and tilt system. The pan and tilt system moves to track the movement of the user's head. When the pan and tilt system is in a misaligned position with the position of the user's head the image displayed to the user is a second portion of the field of capture of the remote pan and tilt system.

Abstract: A telepresence system and method is disclosed for removing error introduced to video images displayed to a user. A remote pan and tilt system tracks the motion of the user's head, and moves a pan and tilt system to capture images of the remote environment. By sensing noise in the movement of the user and/or the motion of the vehicle, error caused by noise is reduced within the displayed video images.

Abstract: A pneumatic tire tread has tread elements formed by circumferential and/or lateral grooves. At least one tread element has a sipe that devolves from a constant width sipe having a three dimensional aspect in at least a portion of the radially outer portion of the sipe to a wider width groove at the base of the tread feature.

Abstract: A tire includes a carcass, a tread band having a radially outer tread surface and a plurality of radially extending recesses, and an anti-slip structure disposed in one of the radially extending recesses. The structure includes a cylindrical housing with a cylindrical flange and a central channel and a stud portion with a shaft and a flange. The shaft is slidingly disposed within the central channel such that a radially outer tip of the shaft may selectably extend radially outward from the cylindrical housing and from the radially outer tread surface in order to enhance traction for the tire. The radially outer tip extends from the cylindrical housing and from the radially outer tread surface when a predetermined air pressure is introduced into the radially extending recess thereby forcing the flange of the stud portion radially outward to abut the cylindrical flange of the cylindrical housing.

Abstract: Both a mold blade for forming sipes and the sipe so formed in a tire tread element have three dimensional portions. In the formed sipe, the three dimensional portion creates a constant interlocking of the opposing sipe faces. The blade and the sipe have at least one row of alternating polygonal shaped recesses and protrusions. The recesses and protrusions terminate in a vertex; the vertex has a planar, or two-dimensional, configuration that is parallel to either-the blade centerline or the sipe centerline.
