摘要： Power control systems and power control devices may include a power control chip having a power control module configured to generate a power stage control signal, and at least one power stage having a timing control module that is physically separate from the power control module. The timing control module may be configured to receive the power stage control signal and generate a timing control signal controlling at least one switch to regulate an output voltage of the at least one power stage. A related method may include generating power stage control information indicating an offset between an output voltage and a desired regulated output voltage, transmitting the power stage control information between modules that are physically separate, and timing signals for controlling a switching converter to regulate the output voltage. A related method of auto-configuring a power control system is also disclosed.

摘要： The subject invention pertains to systems and methods that facilitate generation of a database to support a multidimensional model. A database schema is generated in a top-down fashion. In particular, multidimensional structures and attributes such as cubes and dimensions can be defined. From such definition, a proposed database schema can be produced. This schema can subsequently be modified prior to or after populating the database. For example, a table or column could be added. Thereafter, the cubes and dimensions could be altered and a modified schema generated that preserves changes made to the schema. Accordingly, the subject systems and methods disclose an iterative approach that supports both top-down and bottom-up multidimensional database design.

摘要： A light source in an optical character recognition system is automatically controlled to operate at a plurality of light intensities. A relatively high light intensity is used to illuminate an object bearing indicia to be read. A relatively low light intensity is used at all other times. A plurality of detectors sense reflected or ambient light and produce output signals indicative of the intensity of the reflected or ambient light. First and second signals are generated to indicate whether the detector output is greater than or less than a predetermined threshold. The number of first and second signals generated in response to the outputs of the detectors are summed separately. If the number of first signals equals or exceeds a first predetermined number, the object is illuminated at a high light intensity. If the number of first signals is less than the first predetermined number, or if the number of second signals generated equals or exceeds a second predetermined number, the light source is switched to a low level light intensity.
