    摘要： A DC to DC converter includes a control circuit, a gate driver circuit, and a power stage circuit. The control circuit receives and compares a DC output voltage. When the DC output voltage lower than a first threshold voltage, a PWM signal with a first frequency is outputted, and when the DC output voltage higher than the first threshold voltage, the PWM signal with a second frequency is outputted. The second frequency is higher than the first frequency. The gate driver circuit receives the PWM signal and converts the PWM signal to a first driving signal and a second driving signal. The power stage circuit converts a DC input voltage to the DC output voltage according to the first driving signal and the second driving signal.

    摘要： A method and system for managing semantic and syntactic metadata. Heterogeneous data is received. After the heterogeneous data is received, the semantic metadata associated with the received heterogeneous data is captured and syntactic metadata associated with the received heterogeneous data is captured. The semantic metadata describes contextually relevant or domain-specific information about data based on an industry-specific or enterprise-specific metadata model or ontology. The syntactic metadata included grammatical rules and structural patterns governing an ordered use of formats and arrangement pertaining to specified data. The received heterogeneous data and said captured semantic metadata and said syntactic metadata are logically linked. The heterogeneous data is stored in a repository.

The optical combiner can receive the pump light and the optical signal and an optical prism fixedly installed relative to the housing member. The optical combiner can merge the pump light and the optical signal to form the combined optical signal. The optical prism can direct at least a portion of the optical signal through free space to the optical combiner.
