A seal comprises the combination of a primary seal and a secondary seal each of which acts on at least one shoe that is installed with clearance relative to one of a rotor and a stator in a position to create a non-contact seal therewith. The at least one shoe is provided with a surface geometry and labyrinth-type teeth that influence the inertia of fluid flowing across the seal, and, hence, the velocity of the fluid and the pressure distribution across the seal, ultimately affecting the balance of forces applied to the seal.

A hybrid brush seal is provided for sealing a circumferential gap between two machine components that are relatively rotatable with respect to each other having seal bristles mounted in a ring shape on a first machine component with bristle ends directed at the sealing surface of the second, rotating machine component. The bristle ends are kept from direct contact with the rotating machine component via one or more shoes which create a non-contact seal with the rotating machine component which is enhanced by the imposition of one or more spring elements connected between the machine component and shoes.

A vehicle has a security and anti-theft system that senses movement of the vehicle in a forward or backward direction when the vehicle is in a locked state, such as by detecting wheel rotation. Upon this detection, the security system signals the motor to counteract the wheel movement by rotating one or more wheels in the opposite direction of the direction of wheel rotation detected until the wheel rotation is no longer detected. The security and anti-theft system may determine whether the vehicle is in a locked state by detecting whether a key is present and / or by one or more communications received by an external wireless device.

A hybrid brush seal is provided having two bundles of axially spaced seal bristles each of which are mounted in a ring shape on a first machine component with bristle ends directed at a sealing surface of the second, rotating machine component. The bristle ends are kept from direct contact with the rotating machine component via one or more shoes which are designed such that as the shaft rotates a hydrodynamic film separates the shoe(s) from the shaft. The shoe(s) is attached to the bristle ends at discreet locations. Alternatively, one or more bundles of seal bristles are mounted at one end either to the fixed or rotating machine component, with the opposite bristle ends directed toward one or more shoes, and wherein one or more spring elements are connected between the machine component and shoes.
