Abstract: Methods and systems for implementing such methods for providing server diagnostic and system management information may include, but are not limited to: receiving a network fault status request input; illuminating one or more server node fault indicators for one or more degraded server nodes having one or more faults; receiving a server node fault status request input for a degraded server node having one or more faults; and displaying one or more diagnostic service notifications for one or more faults of the degraded server node. Display of diagnostic service notifications may allow for completion of various service operations associated with service notifications once information specific to a fault is presented. Such service operations may include placing a system in standby mode, transferring workloads to other systems, initiating a firmware update, placing the system in a mode that allows for physical maintenance, or ordering parts associated with one or more faults.

Abstract: Embodiments of the invention include a common mode cancellation circuit and method for correcting signal skew in a differential circuit. According to one embodiment, an op amp circuit is used to correct the mismatch between transmission line lengths in the differential circuit. The CMCC can be embodied as an ASIC and added on to an existing differential signaling systems to correct and compensate for board wiring skew or other causes of phase misalignment. The result is restoration of the cross-over intersection of the plus and minus signals of the differential pair closer to the common voltage level point, as if the signals had been in phase.

Abstract: Stabilized, 17-substituted hydrocortisone containing compositions and methods of manufacture are disclosed. Isomerization of the hydrocortisone component of topical steroid compositions is markedly reduced by including an omega-6 acid component in the form of a free acid or as a compound such as an ester. Specifically disclosed are methods for preventing the isomerization of hydrocortisone 17-butyrate into hydrocortisone 21-butyrate through the use of safflower oil.

Abstract: A circuit for assisting the charging of a line conductor having a distributed resistance and capacitance, such as a word line in a semiconductor memory device, is disclosed. In the conventional memory device, a driver circuit is disposed at one end of a word line, with a circuit for holding unselected word lines at the discharged voltage being disposed at the end of the word line opposite from the drive circuit. The invention is directed towards a pull-up circuit being disposed at the end of the word line opposite the driver circuit, the pull-up circuit having a transistor which is precharged to a high voltage prior to the active cycle. The precharged transistor is discharged as the selected word line is charged by the driver circuit, causing a driving node in the circuit to be connected to a high supply voltage. The driving node is connected to the word line by a transistor which is responsive to a select signal generated by the address decoder; once selected, the word line at the end opposite the driver circuit is driven by the high supply voltage. This will enable the selected word line to be pulled up to the high supply voltage at both ends, thereby reducing the time required to charge the word line to the required voltage level. The pull-up circuit may also include a transistor for holding the word line low, if unselected; this transistor is made non-conductive as the precharged transistor is discharged. Further disclosed is a circuit which allows a plurality of word lines to share the precharging and driving transistors, but which dedicates for each word line the "bleeder" transistor for holding unselected word lines low and the transistors for coupling the driving node to the word line. In addition, a circuit which provides a reduced voltage at the bleeder transistor, thereby speeding up the charging of the word line by the driver circuit, is disclosed.
