摘要： A method for operating an internal combustion engine with compression ignition or with spark ignition as a function of an operating point. A specific residual exhaust-gas quantity in the combustion space is set for compression ignition. The internal combustion engine is operated as a function of the operating point by an outlet cam, by which a first outlet opening phase and a second outlet opening phase take place. The second outlet opening phase commences during an inlet opening phase. At a first operating point in a compression-ignition mode, a residual exhaust-gas quantity in a combustion space is dimensioned as a function of a valve interference set between the inlet and the outlet valve during a charge exchange. At a second operating point in the compression-ignition mode the residual exhaust-gas quantity in the combustion space is dimensioned as a function of a duration of the second outlet opening phase.

摘要： A solenoid torquer system with flux rate feed-back. The system includes a torquer coil and an associated core, and a device adapted to drive a current through the coil having an amplitude proportional to the difference between a coil current command signal and the actual current in the coil. A flux rate servo loop includes a sensor coil coupled to the core to provide a signal representative of the flux rate in the core. This flux rate signal is compared with a flux rate command signal having a ternary width-modulated form. The resultant difference signal is used as the current command signal. The system network provides a precise flux level, or force.

摘要： A device for supplying exhaust gases from an internal combustion engine to a catalytic converter, having multiple exhaust gas supply lines including at least one exhaust gas supply line that serves as a heat-conveying line to promote a transfer of exhaust gas heat to the catalytic converter and at least one other exhaust gas supply line that serve as a heat exchanger to promote an extraction of heat from the exhaust gas upstream of the catalytic converter. A switchable control mechanism controls a flow cross-section of at least one of the exhaust gas supply lines. The exhaust gas supply lines are arranged as a bundle of pipes including individual pipes which are spaced apart and extend to the catalytic converter so that the exhaust gas supply line that is the heat-conveying line is arranged as an inner pipe in the bundle and is surrounded around its circumference by the exhaust gas supply lines that are heat exchangers, which are spaced some distance from one another in a circumferential direction of the heat conveying line. The exhaust gas supply line that is the heat-conveying line has a cross-section that is smaller than a cross-section of the exhaust gas supply line that is the heat exchanger.

摘要： An all digital switching amplifier wherein linearization of the power switch is accomplished solely by using three states. A small, fixed width, bi-state compensating carrier waveform is added to the leading or training edges of an oversampled main input pulse producing a compensated composite waveform. This compensating carrier linearizes output from a power switch by effecting common mode cancellation of switch time errors. Output pulse width combinations for the compensating carrier are obtained from a look-up table stored in memory. A correction mechanism is implemented to correct for harmonic distortion that is dependent on the modulation level or index and results from the compensating carrier modulation. The correction mechanism applies the inverse of the modulation induced distortion to the oversampled compensated composite input signal to null distortion products resulting from the modulation scheme used to apply the small carrier to linearize the performance of the tri-state power switch. Digital timing control of the power switch's deadband ensures accuracy of the timing and sequence in which individual switches within the power switch H-bridge are turned off and turned on, so as to preclude a short circuit across the power supply. A high speed clock used in linearizing the power switch provides a timing reference to generate the necessary deadband timing delays and pulse width increments. The output bridge uses enhancement mode MOSFETs.

摘要： A loudspeaker system using ribbon transducer elements wherein the ribbon elements of the high and mid-range transducer units form a plurality of conductive circuits separated by spaces, or cuts, therebetween which have substantially smooth, undulating wave forms. The magnetic circuit return paths thereof are arranged so as to be remote from and out of the transmitting paths of the acoustic signals generated at such units and the surfaces of the magnetic circuit components and a baffle structure associated therewith are shaped to reduce diffraction effects in the acoustic signals therefrom. A woofer ribbon element has a plurality of interconnected conductive circuit regions to form a generally serpentine shaped circuit, which regions are separated by channels, or cuts, each of which has a smooth, undulating wave form.

摘要： A displacement measuring transducer performs a direct conversion of changes in physical position, particularly angular position, into a digital form suitable for input to a digital microprocessor. The transducer is of the inductive type. Two inductance legs are connected at a common input to form a three-terminal bridge device. To sense positional changes, a step voltage is applied to the input and the transient response at the output of each leg is sampled periodically. Digital circuitry compares the responses of each leg to a fixed reference voltage and produces a binary digital count proportional to the motion sensed by the transducer. This transducer provides high resolution and low noise over a wide dynamic range. It also allows temperature compensation and scale factor calibration.
