  • Publication number: 20150064095
    Abstract: A method of producing a molecular structure comprises determining a desired shape of the molecular structure; providing a multi-layer structure, the multilayer structure having at least first and second adjacent generally planar molecular layers, the first and second generally planar molecular layers each consisting of an array of covalently bonded atoms; arranging the multi-layer structure in a desired orientation relative to a cutter; using the cutter to break bonds within the first generally planar molecular layer to produce a first edge of a desired configuration corresponding to the desired shape of the molecular structure; and using the cutter to break bonds within the second generally planar molecular layer to produce a second edge of a desired configuration corresponding to the desired shape of the molecular structure; and allowing the first edge of the first generally planar molecular layer and the second edge of the second generally planar molecular layer to relax so that the first edge of the first

  • Patent number: 8791680
    Abstract: A voltage regulator includes a first phase power stage, a second phase power stage, and a controller. The first phase power stage includes a zero cross detection circuit configured to measure a current level for the first phase power stage, and to cause a diode emulation state in the first phase power stage when the current level is substantially equal to zero. The second phase power stage is in communication with the zero cross detection circuit, and configured to enter the diode emulation state in response to receiving a signal from the zero cross detection circuit. The controller is coupled to the first phase power stage and to the second phase power stage. The controller is configured to measure an output current of the voltage regulator and to activate the second phase power stage when the output current is above a first threshold current level.
