摘要： Logic circuitry in the form of an integrated circuit includes a number of scannable registers located at various locations of the logic circuitry to continuously sample signal states thereat. In response to signalling from a maintenance diagnostic processor the scannable registers can be commanded to freeze their content for extraction and observation to determining the operating condition of the logic circuitry.

摘要： The present invention pertains to calibration in current sensing applications. Power conversion systems such as those used in computer architectures may employ step down converters such as buck converters or other types of converters. The present invention provides calibration processes and devices to account for various parasitic resistances which are found in such systems. A calibration circuit may be coupled to the buck converter or other power conversion to determine a calibrated voltage signal for the output of the power converter. An effective DC resistance may be determined and programmed for use by a control device used. In this way, the parasitic resistances are taken into account to obtain an accurate estimate of the actual current. In turn, this enables power converters and other devices to operate within specification requirements.

摘要： Aspects of the invention pertain to cooling bundles of power distribution cables or other current carrying cables. Such cables give off heat, especially when carrying high current loads. One or more cooling members are used to secure multiple cables. The cables may be placed about a generally circular shaped member which has a central opening. Receptacles are placed along an outer perimeter of the cooling member to secure the cables. The thickness of each cooling member may vary. When multiple cooling members are used, they may be spaced at least 6 inches apart. The cooling members may be fabricated from a nonconductive material such as PVC.

摘要： Aspects of the invention pertain to optimization of voltage converter efficiency for all load conditions. A signal conditioning circuit is electrically connected to a number of buck converter modules that supply power to different loads. Each module includes a voltage regulator module, which issues a signal that is proportional for its respective load current. The signal conditioning circuit integrates and averages the signals from each voltage regulator module to produce a conditioned voltage signal. The conditioned signal drives a controller, which in turn provides control information to a power conversion circuit. Operation of the signal conditioning circuit cause the controller and power conversion circuit to adapt the driver voltage of the buck converter modules, which improves and optimizes efficiency for all loads.
