Abstract: A method and system for dispensing fuel to a vehicle includes a sensor generating a fuel identifier signal associated with the vehicle and a fuel dispenser having a fuel type a fuel type selector generating a fuel type selector signal. The system also includes a control module in communication with the sensor and the fuel dispenser. The control module compares the fuel identifier with fuel type. When the fuel type corresponds to the fuel identifier, the control module enables a dispensing of fuel from the fuel dispenser. When the fuel type does not correspond to the fuel identifier, the control module prevents the dispensing of fuel.

Abstract: A rotor assembly for an electric device includes a laminated stack of electric steel sheets defining a plurality of longitudinally extending grooves. A conductor bar is disposed within each of the grooves. Each of the conductor bars includes a first end and a second end extending longitudinal outward from opposing axial end surfaces of the laminated stack. The first end and the second end of the conductor bars include a macro-sized locking feature. A first end ring is cast in place over the first ends of the conductor bars, and a second end ring is cast in place over the second ends of the conductor bars. The macro-sized locking feature in the first ends and the second ends of the conductor bars mechanically interlocks with the cast in place first end ring and second end ring respectively.

Abstract: A sealing system for the cylinder head valve seat pocket to valve seat insert interface of a cylinder head assembly comprises a valve seat pocket gasket compressed between a valve seat insert pocket and a valve seat insert having an active layer of material with at least one seal, defining a compression seal at the interface of the seal and the valve seat insert pocket, the valve seat insert or both, to thereby prevent the ingress of fuel or water between the valve seat insert and the valve seat insert pocket.

Abstract: An engine includes a cylinder head at least partially defining a valve seat pocket. A valve seat is located proximate to the cylinder head to at lest partially define the valve seat pocket. A pocket filler is located between the valve seat and the pocket insert such that the pocket filler occupies a substantial portion of the valve seat pocket. A pocket insert is attached to the cylinder head proximate to the valve seat pocket, such that the pocket insert lines at least a portion of the valve seat pocket.

Abstract: A rotor for an induction motor and a method of preparing same. The method includes making a squirrel-cage rotor made up of a cage and a laminate stack by forming a mold around the stack, heating the stack and introducing a molten metal into the mold such that the molten metal substantially fills a space defined in the stack that corresponds to the cage. In one form, the space includes slots or related channels formed in the stack that upon filling with the molten metal become longitudinal bars that form electric current loops with end rings of the cage. By heating the stack and maintaining it at a temperature high enough to keep the molten metal in a substantially molten state at least long enough for it to flow through the slots of the stack, premature freezing of the molten metal is avoided. In addition, by providing low pressure to the molten metal in conjunction with the elevated temperature in the stack, flow is promoted to ensure a substantially porosity-free, fully dense squirrel-cage for the rotor.

Abstract: Methods and technologies to maximize the aging response and the mechanical properties of aluminum alloys are provided. In one embodiment, the aging process for the slowly-quenched aluminum alloys includes, but is not limited to, at least a two-stage solution treatment and a two-stage aging hardening. In the solution treatment, the components are first heat treated at an initial solution treatment temperature and then gradually heated up to about 5° C. to about 30° C. above the initial solution treatment temperature for the material. For the aging treatment, the castings/components are first aged at a lower temperature followed by a higher temperature for the subsequent aging stages. The temperature increase during solution treatment and/or aging can be in steps, in a continuous manner, or combinations thereof. Another embodiment includes a two stage aging process in which there is a non-isothermal aging step.

Abstract: The present invention relates to a method for decorating an ATV part with a camouflage pattern, wherein the ATV body part is made from a polyolefin. The method includes first fluorinating the ATV body part to increase adhesion and then applying a design to the part using a hydrographic process. The method may also optionally include applying a base primer. A clear coat may also be applied. The ATV body part is preferably made from high-density polyethylene.

Abstract: An off-channel leakage power monitor implemented in a transceiver (100) dynamically measures adjacent and alternate channel leakage power produced by nonlinearities in a transmitter (110) power amplifier (116). A main local oscillator (124), offset voltage-controlled oscillator (122), and second local oscillator (170) are adjusted to obtain on-channel power, adjacent channel power, and alternate channel power measurements using a measurement calculator (185) implemented in a digital signal processor (180) or as a gate array in a receiver (140). Once the off-channel leakage power measurements have been obtained, any number of techniques can be used to extract increased efficiency from the power amplifier (116) while maintaining acceptable linearity under changing operating conditions.

Abstract: A unique method and apparatus for detecting the power level of communication signals, such as RF communication signals being transmitted from a wireless communication device (100), increases the dynamic range of a conventional power detector. The method and apparatus selectively switches between two power detection paths (314, 317) with different operating ranges. More particularly, when a transmitted signal having a power within a predetermined range is detected, a first path is biased to transmit the RF communication signal. The predetermined range could be determined, for example, by a number of power steps. Similarly, when a transmitted signal having a power in a second predetermined range is detected, such as a low power transmitted signal, a second path provided. Preferably, the second path includes an amplifier (372) to offset the loss of resolution as the detect voltage is low.
