摘要： The present disclosure describes self-biasing radio frequency circuitry. In some aspects a radio frequency (RF) signal is amplified via a circuit having a first transistor configured to source current to an output of the circuit and a second transistor configured to sink current from the output of the circuit, and another signal is provided, without active circuitry, from the output of the circuit to a gate of the first transistor effective to bias a voltage at the output of the circuit. By so doing, the output of the circuit can be biased without active circuitry which can reduce design complexity of and substrate area consumed by the circuit.

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. 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.

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.

摘要： An exemplary embodiment of a power converter is provided. The power converter includes a transformer, a power device, a switching controller, and a capacitor. The power device is coupled to the transformer for switching the transformer to product output of the power converter. The switching controller receives a feedback signal for generating a switching signal coupled to drive the power device. An input circuit of the switching controller is coupled to the transformer to sample an input signal for generating the feedback signal, and the input signal is correlated to the output of the power converter. The capacitor is coupled to the switching controller to provide frequency compensation for a feedback loop of the power converter. Input of the power converter is without an electrolytic capacitor, and a maximum output current of the power converter is a constant current.

摘要： 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.
