  • Patent number: 9219414
    Abstract: A switching regulator or other apparatus or techniques can include load current monitoring to provide a digital representation of an estimated load current. Load current monitoring can be performed by a circuit including a counter circuit, a comparator circuit, and a digitally-controlled source coupled to the counter circuit and configured to adjust a bias condition of a sensing device in response to a count provided by the counter circuit in order to establish a proportional relationship between a current conducted by the sensing device and a corresponding current conducted by a power switching device. The counter circuit is configured to increment and decrement the count in response to information provided by the comparator output and the count is generally indicative of the estimated load current, such as an average load current.

  • Patent number: 9209688
    Abstract: In one aspect, this disclosure relates to a method of controlling current output from a switching regulator to a load via an inductor. Inductor current information can be sampled at a peak level, such as just before a transistor configured to cause current to flow through the inductor is turned off. The sampled inductor current can be compared with a reference current, and a current limit threshold can be adjusted based on the comparison. The output current of the switching regulator can be controlled based on a comparison of the current limit threshold with an indicator of current flowing through the inductor. This method can accurately and efficiently limit current in a switching regulator.

  • Publication number: 20150175510
    Abstract: The invention discloses a method for preparing high-content zeaxanthin. In the conventional preparation methods, some methods adopt certain toxic organic solvents; some methods require the multi-step crystallization process; and some methods are featured by long reaction time, high temperature and lower product yield, thus being not suitable for industrial production. The invention adopts lutein crystal or its fatty acid ester as the raw material and utilizes isomerization reaction to produce zeaxanthin, and is characterized in that a mixed catalyst consisting of an organic base catalyst and a cocatalyst is used in the isomerization reaction, wherein the cocatalyst is palladium carbon. The invention has the advantages of simple process route, low reaction temperature, short reaction time, good product purity and high yield, thus being suitable for industrial production, and no poisonous and harmful organic solvent residues in the product, thus being suitable for the use as a food additive or drug.

  • Publication number: 20150123649
    Abstract: Apparatus and techniques for controlling measurement of an electrical parameter of an energy source can be used to obtain information for use in enhancing a power transfer efficiency between the energy source and a load. For example, during a first measurement cycle, information indicative of the electrical parameter of the energy source can be obtained using a measurement circuit during a first sampling duration in which the load is decoupled from the energy source. The information indicative of the obtained electrical parameter can be compared to a threshold. In response to the comparing, a different second sampling duration can be determined for use in obtaining information indicative of the electrical parameter during a subsequent measurement cycle. The information indicative of the electrical parameter of the energy source includes information for use in enhancing the power transfer efficiency between the energy source and the load.
