摘要： A converter includes a transformer having a primary winding, a secondary winding and an auxiliary winding, a first switching device for connecting an input voltage to the primary winding of the transformer, an output circuit connected to the secondary winding, a controller, and an integrated active clamp and primary bias circuit. The integrated active clamp and primary bias circuit includes the auxiliary winding and a second switch providing a bias voltage to the controller to alternately operate the first and second switches between conductive and non-conductive states. When the first switch is conductive the second switch is nonconducting and power is transferred from the primary winding to the output circuit via the secondary winding and from the auxiliary winding to the controller. When the first switch is nonconducting, the second switch is conducting and the voltage across the primary switch is clamped.

摘要： An advanced data capture architecture is disclosed which enables the free-definition and re-definition of the format of document forms without requiring any reprogramming of the data processors which capture and use the data on the completed forms. The architecture encompasses the interactive operation of a host processor and one or more workstations in a data processing system. It includes the interaction between a host processor and a workstation in providing a list of common operand names which are meaningful to an application program running on the host. It includes the operation of the workstation creating a new document form using the list of common operand names. It includes the workstation performing character recognition of the filled-out form, transforming its information into coded data. It includes the workstation assembling a field data segment for each field, containing the common operand, the coded data and the popular name for the field. And it includes the operation of the host processor receiving the assembled field data segments from the workstation and providing the coded data to the application program which processes the information right from the form.
