Abstract: Metal object detection may be performed in a wireless power system by monitoring the 5th or other order harmonic current of a dual-frequency power transmitter driven by a voltage-fed inverter with square-wave output. While power transfer is maintained by tuning at the fundamental frequency, the transmitter circuit is tuned simultaneously at the 5th order frequency or other harmonic frequencies to increase or decrease the flow of the harmonic current for when a metal object is present. The receiver circuit may include a notch filter to filter out the 5th order frequency. With the dual-frequency tuning configuration, the presence of a metal object causes a significant drop of the increase in the harmonic current at the transmitter side while the receiver behaves as an open circuit with no effect on power transfer. The harmonic tuning circuit may be switched off as necessary to leave only the fundamental frequency for power transfer.

Edges of the two second side surfaces proximate to the second surface intersect at a second intersection line. A distance between orthographic projections of two adjacent first intersection lines on the second surface is less than a distance between orthographic projections of two adjacent second intersection lines on the second surface.

Abstract: Provided is a synthesis apparatus for synthesizing biomacromolecules. The synthesis apparatus includes a feeding apparatus, a recognition apparatus, a reaction apparatus, a sorting device, and a transfer device. The feeding apparatus includes a transporting assembly that can simultaneously transporting biochips. The recognition apparatus recognizes an identification of each biochip on the transporting assembly and feed back an identification information to a control device. The reaction apparatus includes various reaction vessels for performing synthesis reactions on the biochips. The sorting device includes various first sorting assemblies located on a side of the transporting assembly and correspond to the reaction vessels. The first sorting assemblies sort the chips on the transporting assembly to the reaction vessels corresponding to the current synthesis reactions when controlled by the control device. The transfer device transfers the biochips in the reaction vessels to the feeding device.

Abstract: A chuck for use with a rotary power tool having an output spindle. The chuck includes a base and an inner sleeve threadedly coupled to the base. The inner sleeve has a central aperture. A collet is disposed within the central aperture of the inner sleeve and configured to be engaged by a portion of the inner sleeve to be tightened or untightened. The chuck further includes an outer sleeve surrounding the inner sleeve, and a detent member disposed between the inner sleeve and the outer sleeve. The detent member is coupled for co-rotation with the outer sleeve and configured to selectively transmit torque from the outer sleeve to the inner sleeve. When the collet is tightened, rotation of the outer sleeve causes axial displacement of the detent member relative to the inner sleeve as the outer sleeve and the detent member rotate relative to the inner sleeve.
