  • Patent number: 8351232
    Abstract: Various exemplary embodiments relate to a power factor corrector for low loads and a related method. The power factor corrector raises power factor at low loads or high mains voltages by having the a greater amount of current delivered to the load during the falling time of the absolute value of the mains AC voltage than during the applicable rising time. Various embodiments achieve this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time. This may involve using a timing voltage increasing over a period within each half mains cycle to increase the switch-on time of conversion cycles in the falling time. This may also involve shifting the power conversion in time domain during each half mains cycle so that a majority of the time occurs during the falling time. Various embodiments may employ both methods.

  • Publication number: 20120300517
    Abstract: A power factor corrector raises power factor at low loads or high mains voltages by modifying the switch timing or the current received by the power converter. It achieves this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time, to thereby control the current received by the converter to compensate for current received by the intermediate filter. Some embodiments may employ a feedback system to produce one or more error signals that modify the control signal used to control the operation of the converter. Various embodiments may also include additional stages that limit the compensation range of the error signal.

  • Publication number: 20120286217
    Abstract: Novel methods for manufacturing carbon nanostructures (e.g., carbon nanospheres) that are highly dispersed include forming a precursor composition, polymerizing the precursor composition, extracting water from the polymerized carbon material using an organic solvent, and carbonizing the polymerized material (e.g., through pyrolysis) to form the carbon nanostructures.

    Abstract: A biosensor for determining the concentration of an analyte in a biological sample. The biosensor comprises a support, a reference electrode or a counter electrode or both disposed on the support, a working electrode disposed on the support, the working electrode spaced apart from the other electrode or electrodes on the support, a covering layer defining a sample chamber over the electrodes, an aperture in the covering layer for receiving a sample, and at least one layer of mesh in the sample chamber between the covering layer and the electrodes. The at least one layer of mesh has coated thereon a silicone surfactant. Certain silicone surfactants are as effective as fluorinated surfactants with respect to performance of biosensors. These surfactants, when coated onto the mesh layer of the biosensor, are effective in facilitating the transport of aqueous test samples, such as blood, in the sample chamber.

  • Patent number: 8193797
    Abstract: An energy converter is disclosed in which self oscillation mode operation is improved by a closed loop feedback control. The feedback control utilizes the voltage error from the voltage valley in the drain voltage (Vdrain) of the converter switch (1), to determine an error (E(n)) in the time domain. Control circuitry (61, 62, 63) is used to minimize this time-domain error (E(n)) to optimize the control of the switch mode converter.
