Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.

Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.

Abstract: A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.

Abstract: A rotational position of a variable-vane of a variable-vane turbine nozzle upstream of a turbine of a gas-turbine engine is biased towards a corresponding rotational position that will mitigate against an overspeed condition of the turbine during operation of the gas-turbine engine. When the turbine is operating at a rotational speed that is less than an overspeed threshold, the rotational position of the variable-vane is controlled independently of the biasing using a variable-vane actuator operatively coupled to the variable-vane. Responsive to a rotational speed of the turbine in excess of the overspeed threshold, the variable-vane actuator is operatively decoupled from the variable-vane so as to provide for the variable-vane to be repositioned towards the corresponding rotational position that will mitigate against the overspeed condition.

Abstract: A powerplant and a generator of an external auxiliary power unit (APU) are located within a nacelle that is mountable to a hardpoint of an aircraft via an associated a hardpoint attachment interface that provides for releasably coupling the external APU thereto, and provides for coupling a fuel supply of the aircraft to run the powerplant, and coupling electrical power from the external APU either to, or external of, the aircraft. The external auxiliary power unit (APU) incorporates a particulate filter in series with the inlet air flow to the powerplant.

Abstract: Exhaust gases from an engine, input to turbo-compounder, drive a bladed turbine rotor therein, which drives a multi-phase AC generator, the output of which is used to electrically drive a multi-phase induction motor, the rotor of which is mechanically coupled to the engine, so as to provide for recovering power to the engine. The multi-phase AC generator may be coupled to the engine either by closure of a contactor, engagement of an electrically-controlled clutch, or by control of either a solid-state switching or control system or an AC excitation signal, when the frequency (fGENERATOR) of the multi-phase AC generator meets or exceeds that (fMOTOR) of the multi-phase induction motor.
