摘要： A two-pin transmit/receive switch design includes a switching component configured to selectively switch in elements for a transmit signal path and elements for a receive signal path. A capacitor in the transmit signal path may be switched out when receiving signals on the receive signal path. Being able to selectively switch out the capacitor allows the capacitor value to be selected for optimal operation during transmit mode. For example, insertion loss may be minimized. In addition, elements in the receive signal path may be optimized (e.g., impedance matching) without being affected by or affecting the optimization that was performed for the transmit signal path.

摘要： 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.

摘要： 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.

摘要： 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.
