摘要:
Systems and methods for detecting states are disclosed. An information handling system may include a processor and a plurality of information handling resources communicatively coupled to the processor via the common control line. The processor may be configured to produce a first signal on a common control line. Each of the plurality of information handling resources may include a tag having a signal threshold, the tag configured to communicate a second signal via the common control line indicating the presence of the particular information handling resource in response to the first signal exceeding the signal threshold of the tag.

A method of using a counter stored in flash memory includes providing a base value field, a selector field, and a plurality of increment fields. The base value field represents a base value for the counter, and the selector field indicates a first one of the increment fields. The method further includes changing a bit of the first increment field from an erased value to a written value to indicate a change in a value stored in the counter.

A method for compact encoding including providing a first value field allocated in a first portion of a memory, wherein a portion of the first value field is utilized to store a fixed-size variable. A most significant zero bit (MSZB) is located in the first value field, and it is determined if the fixed-size variable can be written in a first area without performing an erase operation. The first area includes the N bits following the MSZB in the first value field. The fixed-size variable is written into the first area if the fixed-size variable can be written without performing the erase operation.

A switched power rail monitor compares voltages provided by a switched power rail and a power source to detect a predetermined differential indicative of a fault at the switched power rail. A switched power rail fault is communicated to a power manager to take corrective action, such as cutting off power to information handling system components. In one embodiment, a pair of bipolar junction transistors monitor the voltage differential to send an enable signal if the differential is within limits and a disable signal if the differential exceeds limits.

An information handling system (IHS) employs a power fault protection circuit to protect the IHS from overvoltages which may occur on an information line from a power adapter to the IHS. The system includes a processor coupled to the protection circuit. The circuit is operative in a first mode to decouple an information line from the IHS in response to a disable command and operative in a second mode to decouple the information line from the IHS when a voltage in the information line exceeds a predetermined threshold voltage.

A portable information handling system (IHS) includes an external module which derives its power from the internal unregulated DC power rail of the IHS. An IHS power subsystem includes a multiple threshold current protection circuit which continuously monitors power usage by the external module. The multiple threshold current limit protection circuit dynamically adjusts the current limit depending on whether the IHS is powered by an AC source or a DC battery source.
