    Abstract: A camshaft phaser includes an input member connectable to the crankshaft of the internal combustion engine; an output member connectable to the camshaft of the internal combustion engine and defining an advance chamber and a retard chamber with the input member; a valve spool coaxially disposed within the output member such that the valve spool is rotatable relative to the output member and the input member, the valve spool defining a supply chamber and a vent chamber with the output member; and an actuator which rotates the valve spool in order to change the position of the output member relative to the input member by supplying pressurized oil from the supply chamber to one of the advance chamber and the retard chamber and venting oil to the vent chamber from the other of the supply chamber and the advance chamber.

    Abstract: A metal interconnect for a fuel cell stack is formed from an electrically conductive metal sheet having at least four stamped slots through the metal sheet, and often many more than four slots. The stamped slots individually extend lengthwise parallel to the direction of fluid flow during operation of the fuel cell stack assembly and are disposed on the metal sheet in a pattern extending parallel and perpendicular to the direction of fluid flow, so as to define at least one metal strip portion between adjacent slots extending parallel to the direction of fluid flow and at least one metal strip portion between adjacent slots extending perpendicular to the direction of fluid flow. The metal strip portion(s) include portions of reduced thickness that allow for fluid flow between adjacent slots and portions of greater thickness that provide discrete locations of electrical connection between the separator plate fuel cell electrode.

    Abstract: A radar system includes a radar antenna and a controller. The antenna includes a reference element, an alpha element spaced apart from the reference element by one half-wavelength of the reflected signal, and a beta element spaced apart from the reference element by an even number of half-wavelengths of the reflected signal. The controller is configured to determine an alpha phase difference between detected signals from the reference element and the alpha element, determine a beta phase difference between detected signals from the reference element and the beta element, and determine a first virtual phase difference that corresponds to the reflected signal expected to be detected by a first virtual element located halfway between the reference element and the beta element. The first virtual phase difference is based on the beta phase difference divided by two.

    Abstract: A connector assembly includes a first connector that includes a ramp. A second connector has a pump handle that includes laterally spaced legs joined at a hook. The hook is configured to interlock with the ramp in an intermediate assembled condition that provides continuity between the first and second connectors. The pump handle has a lower surface. A positional assurance element is movably supported on the second connector and includes a tongue that is arranged between the legs. The tongue includes an upper surface that extends beyond the lower surface such that the tongue and the pump handle overlap one another with the first and second connectors in a nested but unassembled condition. The positional assurance element is configured to move from a retracted position to an extended position while in the intermediate assembled condition to provide a fully assembled condition.
