Abstract: A controller for a power converter includes a clamping circuit, a switching circuit and a pulse generator. The clamping circuit is coupled to an input terminal of the controller for detecting a detection signal from a transformer. The switching circuit generates a switching signal to switch the transformer in response to the detection signal for regulating the power converter. A maximum level of the detection signal is clamped to be under a level of a threshold voltage during an off-period of the switching signal. Since the maximum level of the detection signal is clamped and the oscillating energy of the reflected signal is discharged, the speed of detecting the detection signal is increased. Therefore, the regulation of the primary-side controlled power converter can be improved accordingly.

Abstract: A method and an apparatus of operating a primary-side-regulation power converter at both continuous current mode and discontinuous current mode are provided. The apparatus includes a switching circuit, a signal generator, a correlation circuit, and a feedback modulator. The signal generator generates a half signal and a second sampling pulse in response to a switching signal. The correlation circuit receives the half signal, the second sampling pulse and a switching-current signal for generating a modulating current. The feedback modulator modulates a feedback signal in response to the modulating current, a detection signal and the switching signal. The detection signal obtained from a transformer is correlated to an output voltage of the primary-side-regulation power converter. An on-period of the half signal is half of an on-period of the switching signal. The switching-current signal is sampled at a falling-edge of the half signal.

Abstract: A system for obtaining incremental and absolute displacement measurements using systems of electrodes that interact to form variable capacitors and systems that facilitate implementation of the method along with exemplary embodiments of these systems. The capacitors created by the disclosed method have known physical properties and corresponding known mathematical relationships. These laws are exploited in such a way by our method as to overcome inadequacies in existing systems and create superior systems. These superior systems improve upon the existing art by including economically and reliably made sensors based on the area varying principle which eliminate dead zone issues and increase accuracy through a reduction of the influence of gap variations on capacitive systems through the use of compensatory geometrical arrangements of multiple capacitive systems.

Abstract: A control circuit of the power converter according to the present invention comprises a feedback circuit, an output circuit and an adaptive clamping circuit. The feedback circuit generates a feedback signal in accordance with an output of the power converter. The output circuit generates a switching signal in accordance with the feedback signal for regulating the output of the power converter. The adaptive clamping circuit limits the level of the feedback signal under a first level for a first load condition. The feedback circuit determines a slew rate of the feedback signal for increasing the level of the feedback signal from the first level to a second level. The adaptive clamping circuit is disabled and the level of the feedback signal can be increased to the second level for a second load condition.

Abstract: A series of p105-based NF-κB super repressors, designated p-105(sr), have been designed. The p105(sr), no longer generates p50 and undergoes signal-induced degradation, effectively inhibiting all NF-κB activities. Additionally, p105(sr) significantly enhances tumor necrosis factor alpha (TNF-α)-mediated killing of MT1/2 skin papilloma cells when p50 homodimer activity is elevated. p105(sr) is an effective NF-κB super repressor with a broader range than other currently available IkBα super repressors. The novel repressor can be used in cells where a noncanical NF-κB activity is dominant or multiple NF-κB activities are activated.

Abstract: A housing has upper, lower, and central sections having a common axis and forming an interior chamber. An opening in the intermediate section has upper, lower, and sides edges. A flap has one edge coupled with the opening and covers the opening. A support is slidable between extended and retracted orientations. The support has central, upper, and lower extents. A cylindrical bore extends through the support. The support has legs, including a short leg, extending downwardly and outwardly and adapted to be radially contracted with the short leg within the opening restrained from downward movement. The flap is adapted to be depressed to move the short leg from contact with the opening and spring the legs outwardly to move the support from the extended orientation to the retracted orientation. Upper and lower needles extend from the upper and lower extents of the support for movement therewith.
