Embodiments of the present invention address deficiencies of the art in respect to via structure utilization in a PCB design and provide a novel and non-obvious method, system and computer program product for impedance discontinuity remediation for via stubs and connectors in a PCB. In one embodiment a method for impedance discontinuity remediation in a PCB can be provided. The method can include configuring a pre-distortion filter to negate an impedance discontinuity in an electrical signal caused by a transmission line with one of a via stub or a connector. The method further can include pre-distortion filtering an electrical signal before transmitting the electrical signal over the transmission line. Finally, the method can include transmitting the pre-distortion filtered electrical signal over the transmission line.

A bi-directional voltage translator is disclosed. The bi-directional voltage translator includes a step-up voltage translator for converting signals of a first voltage level to signals of a second voltage level, and a step-down voltage translator for converting signals of the second voltage level to signals of the first voltage level. The step-up voltage translator includes a first source sense circuit, a first block feedback circuit and a first output driver circuit. The step-down voltage translator includes a second source sense circuit, a second block feedback circuit and a second output driver circuit.

A first aspect of the present invention is a method controlling an orientation-dependent component in a computer system. The method comprises the steps of interpreting a signal, the signal being based on an orientation of the computer system and automatically reconfiguring the orientation-dependent component based on the interpretation of the signal. A second aspect of the present invention is a system for controlling an orientation-dependent component in a computer system. The system comprises means for interpreting a signal, the signal being based on an orientation of the computer system and means for automatically reconfiguring the orientation-dependent component based on the interpretation of the signal. Through the use of the method and system in accordance with the present invention, orientation-dependent components are automatically reconfigured when a computer is changed from a rack orientation to a tower orientation (or vice versa) without having to manually adjust the settings of the components.

A high-speed data transport system for use in computers, switches, microprocessors or the like includes a low impedance differential bus and a plurality of transceivers connected to the bus. Each of the transceivers is provided with a driver circuit which places data onto the bus and a receiver for accepting data from the bus. The driver includes a pseudo-differential current driving circuit arrangement which sinks current from only one side of the bus while the other side of the differential bus is undisturbed. The receiver includes a differential comparator biased to a preferred output voltage level.

An apparatus for carrying out, at frame rates, entity detection and verification on bit-mapped raster graphic systems by providing an entity identification bit sequence with each feature of the picture displayed. The apparatus includes a display coupled to a store for input data, serially sending items of data to the display, together with means for identifying the items of data so supplied, such that all the items of data forming a selected feature, i.e., line, circle, background or etc. of the display can be identified, and stored. Comparison and register means are used to drive a modulating means to verify the display of the items of data, forming the selected feature, when a correlation occurs between the selected feature and the feature formed by the items of data sent from the store. Verification may be emphasizing, i.e., brightening, flashing, color change, etc. the feature selected.

A high voltage/high current circuitry includes a push-pull voltage amplification stage connected in tandem with a parallel connected push-pull current amplification stage. For the voltage amplification stage a pair of bipolar operational amplifiers are connected in parallel and operate in a push-pull manner. A pair of switching means are positioned at the output of each of the bipolar operational amplifiers while the outputs of the amplifiers are connected to the inputs through a current gain regulating means, an isolation means and a voltage divider means.
