摘要:
A variable magnetization machine control system comprising a controller configured to adjust a d-axis current waveform and a q-axis current waveform in accordance with an operating condition of a variable magnetization machine to generate an adjusted d-axis current waveform and an adjusted q-axis current waveform that provide a driving voltage to drive the variable magnetization machine at a predetermined speed while maintaining the driving voltage below a predetermined maximum magnitude.
摘要:
A variable magnetization machine controller including a hysteresis control component configured to receive an ideal magnetization state signal, output an actual magnetization signal based on the ideal magnetization state signal for control of a variable magnetization machine, and modify the actual magnetization state signal in accordance with an error value between the ideal magnetization state signal and the actual magnetization state signal.

A compression ignition engine uses two or more fuel charges having two or more reactivities to control the timing and duration of combustion. In a preferred implementation, a lower-reactivity fuel charge is injected or otherwise introduced into the combustion chamber, preferably sufficiently early that it becomes at least substantially homogeneously dispersed within the chamber before a subsequent injection is made. One or more subsequent injections of higher-reactivity fuel charges are then made, and these preferably distribute the higher-reactivity matter within the lower-reactivity chamber space such that combustion begins in the higher-reactivity regions, and with the lower-reactivity regions following thereafter. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot).

A device and a method for isolating a target from a sample are provided. The target is bound to solid phase substrate to form a target bound solid phase substrate. The device includes a first plate having a first region for receiving at least a portion of the sample. A second plate is spaced from the first plate by a distance and has a first region for receiving a reagent. A force attracts the target bound solid phase substrate toward the first region of the second plate such that the target bound solid phase substrate in the portion of the sample are drawn through the air gap and into the reagent by the force.

The present disclosure relates to the use of pharmaceutical agents to manipulate serotonin in animal mammary glands. Use of the serotonin agents results in increased PTHrP levels, resulting in the release of calcium from the bone, which improves lactation.
摘要:
A method and computer program product for suppressing the symptoms of multiple sclerosis (MS) by irradiating a subject exhibiting the symptoms with a predetermined dose of UV-containing light from a light source and detecting a suppression of the clinical symptoms of MS. In particular, the detected suppression of the clinical symptoms is disassociated from the vitamin D production within the subject.
摘要:
The present invention provides high-speed, high-efficiency PIN diodes for use in photodetector and CMOS imagers. The PIN diodes include a layer of intrinsic semiconducting material, such as intrinsic Ge or intrinsic GeSi, disposed between two tunneling barrier layers of silicon oxide. The two tunneling barrier layers are themselves disposed between a layer of n-type silicon and a layer of p-type silicon.
