Abstract: The reciprocatable power piston of a free-piston Stirling machine is drivingly linked to a reciprocatable component body of an associated apparatus by at least one spring with no rigid connection linking the piston to the component body. The spring drive linkage allows the power piston and the reciprocatable component body of the associated apparatus to reciprocate at different amplitudes of oscillation. Therefore, the Stirling machine and the associated apparatus can be optimized at different amplitudes of piston and the component body oscillation thereby improving the optimization of two very different dynamic systems that are drivingly connected together.

Abstract: A circuit and method for controlling a smart, high side driver with current and temperature sensing so that it can turn ON a relatively high current load of incandescent lamps or similar loads within a practical time. The output of the high side driver is sensed. In response to the coexistence of an ON command applied to the control input of the high side driver and the output terminal of the high side driver switching to an OFF state, an OFF command is applied to the control input of the high side driver. That OFF command is maintained for a selected cooling time interval. An ON command is applied to the control input of the high side driver after the selected cooling time interval. The selected cooling time interval is at least long enough to allow the MOS/FET temperature to cool to the thermal reset of its status temperature TRS, which is the temperature below which the driver operates with its highest current limit ILIMH when it is turned back on.

Abstract: A method for detecting a quantitative measure of a physiologic state of a human myocardium or coronary artery. Implementations of the method detect the extent of change of myocardial electrical impedance from a mean baseline value to provide diagnosis of the extent of ischemia, stenosis, tissue rejection, and reperfusion and the effectiveness of cardioplegia and ischemia pre-conditioning as well as the general effectiveness of coronary bypass surgery as measured by post-operative reperfusion. Electrodes are attached to the myocardium, baseline measurements of the mean myocardial electrical impedance are stored and the variance of the myocardial electrical impedance and a baseline value of mean myocardial electrical impedance are computed from the baseline measurements and stored. Mean myocardial electrical impedance values are periodically measured between each electrode pair over an interval of time and stored.

Abstract: A tool for boring has an axle for drivingly linking at a first end to a portable rotatable machine. At a second end, the axle has a shaft-receiving bore into which a nose shaft is inserted. The nose has a cutting tip and a flight cutter that aligns with a flight on the axle. An insulator is electrically interposed between the cutting tip and the nose shaft, thereby electrically insulating the nose shaft from the cutting tip. The flight cutter performs the high-wear cutting at the leading edge of the flight, thereby causing the flight to merely remove the soil or other particulate from the hole being formed.

Abstract: A divider for keeping current-carrying conductors separated transversely in raceways, such as walker ducts and cable trays, in which multiple conductors extend, in order that air can flow around the conductors and cool the conductors. The divider is mounted in the raceway to form passages through which some of the conductors can extend spaced from other conductors. Two separators are mounted together and preferably mounted to the raceway sidewall, forming at least a base passage between the separator and the sidewall of the raceway, and an elevated passage between the walls of the separators.

Abstract: A feedback control method and circuit for inclusion in a control system of an electrical power generating source that comprises a free piston Stirling engine driving a linear alternator. An instantaneous value of a variable, Vinternal, is continuously derived from other sensed and computed parameters and used in a negative feedback control loop of the control system to control engine piston stroke in order to maintain the power produced by the engine equal to the power transferred from the engine to the alternator. Vinternal is the sum of the voltage induced on the alternator winding and the voltage across the equivalent circuit lumped resistance of the alternator winding. A switching mode rectifier connects the alternator winding to an energy storage capacitor or battery. A negative feedback, alternator current control loop has an output connected to the pulse width modulator of the switching mode rectifier and has a feedback circuit comprising a current sensor for sensing instantaneous alternator current.

Abstract: An optical interferometer used to measure the current in a conductor, where the gap between the mirror and the quarter wave plate is minimized, and the gap is shielded magnetically. Additionally, at least the modulator is shielded, and preferably the case containing many of the components, such as the integral number of turns of optical fiber in a coil, is magnetically shielded. By shielding the components, and reducing the gap between the quarter wave plate and the mirror, the error in the current measurement is substantially reduced.

Abstract: The concentricity and coaxiality of a central bore through a piston for a free piston Stirling machine is improved with a piston that has a sleeve with a core constructed from at least two, separate, axially-engaging core components sealed within the sleeve. During fabrication, a central bore is machined through each of the core components. The piston is assembled by heating the sleeve and cooling the core components, inserting the core components into the sleeve and then allowing the sleeve to cool and the core components to warm. This drives the core components into sealed engagement with each other and with the sleeve and aligns the central bore coaxially with the outer cylindrical surface of the sleeve.
