Abstract: An information handling system includes a power supply unit (PSU) and a motherboard. The PSU provides power to components of the information handling system, and includes power monitoring circuitry and digital-to-analog (D/A) circuitry. The power monitoring circuitry of the PSU determines whether the provided power exceeds one of a plurality of thresholds during a respective one of a plurality of time periods, and provides a digital value on one of a plurality of pins based on one of the threshold voltages being exceeded during the corresponding time period. The D/A circuitry of the PSU detects the digital value on one of the pins, and provides one of a plurality of quantized voltages. Each of quantized voltages corresponds to a different one of the pins. The motherboard receives the one of quantized voltages, and activates a throttling operation based on the received one of quantized voltages.

Abstract: A system for detecting and remediating a discharge of fuel from a fuel source facility is disclosed. The system can comprise a contamination detection subsystem configured to detect a discharge of fuel from the fuel source facility and a remediation subsystem configured to remediate contamination due to the discharge of fuel. A controller can automatically activate the remediation subsystem upon detection of a discharge by the contamination detection subsystem. The controller can automatically send a notification that a contamination has been detected and the remediation system has been activated. Alternatively or in addition, the controller can automatically send a notification that a contamination has been detected and the remediation system has been activated.

Abstract: Energy beams with different wavelengths or wavelength ranges may be passed through a gas sample in a test chamber. Ones of the energy beams may have wavelengths or wavelength ranges that are absorbed by particular gases. To determine whether any of those particular gases are in the gas sample, the loss of energy, if any, as the beams pass through the gas ample may be determined. The presence of one or more gases that do not absorb the energy beams may be determined by placing a chemical reactant that reacts with those one or more gases and then detecting a chemical reaction between the chemical reactant and the gas sample.

Abstract: A microcontroller has many internal peripheral devices. The peripheral devices are coupled to a scan path. A memory storage device that is external to the microcontroller is also coupled to the scan path. When commanded, data is shifted out of each device configuration register onto the scan path and stored in the external memory device. This is particularly useful for obtaining the states of each device without bringing down the application. Furthermore, configuration data stored in external memory can be loaded into the peripheral device configuration registers via the scan path. This invention also supports zero-volt suspend/resume which does not need extra software readable shadow registers which are often required in other architectures for reading back the current state of legacy registers which are read-only.

Abstract: The scalable virtual timer system or subsystem implements multiple hardware timers with minimal silicon overhead. In one embodiment, for each virtual timer of a plurality of virtual timers, a content addressable memory stores a sum of an “initial state” of a free running counter and a desired count duration for the virtual timer. When the stored value matches a current state of the free running counter, the content addressable memory generates a terminal count for the virtual timer. In an alternative embodiment, for each virtual timer, a period register of a set of period registers stores a sum of a desired count duration for a virtual timer and an “initial state” of the free running counter. A comparator of a set of comparators generates a terminal count for a virtual timer when a current state of the free running counter matches the sum stored in a period register associated with the virtual timer.

Abstract: A method of remediating a site of earth and groundwater contamination includes the steps of drilling at least one injection well, and preferably a plurality of injection wells, into the groundwater in a contaminated area. At least one, and preferably a plurality of extraction wells, are drilled into the earth above the groundwater, the vadose zone, in the contaminated area. The surface of the earth above the contaminated area is sealed, such as by a layer of concrete, asphalt, or plastic sheeting. Air and nutrients are injected into the contaminated area through the injection wells. The air is injected on a substantially continuous basis while the nutrients are injected on a batch basis. Air and vapor is extracted on a substantially continuous basis from the contaminated area by the extraction wells, which may be either vertically or horizontally positioned.

Abstract: A personal information device is provided, which includes an integrated circuit coupled to a variety of peripheral devices. The integrated circuit is configured with a core section and one or more input/output sections. The core section is powered independently of the input/output sections, allowing selective power down of peripheral components coupled to the integrated circuit without the use of external buffers. The input/output sections are configured with unique input/output circuits which perform the buffering task. The integrated circuit is further configured with a partial reset. The partial reset selectively forces portions of the integrated circuit to an initial state while other portions continue to operate. One particular embodiment of the integrated circuit is configured with a CPU and an RTC unit which comprises configuration RAM and a real time clock facility. When the partial reset is activated, the RTC unit is not reset but the CPU is reset.

Abstract: A portable computer system with a special connector, on the motherboard, into which a field-installable boot card can be inserted. The special motherboard connector is wired so that the operator, by setting connections on the field-installable boot card, can bypass the boot memory on the motherboard and force the computer to boot from the memory on the boot card. This permits a technician, in the field, to temporarily override the internal nonvolatile memory which holds the basic system software. This permits recovery of a system in which the basic system software has been corrupted. Preferably the motherboard boot memory is a flash EPROM, and can be rewritten, by setting appropriate jumpers on the boot card, after the computer has booted from the boot card. The motherboard connector is preferably located on the motherboard, and is accessible through a removable cover. This connector can also preferably be used for temporary attachment of a diagnostic display card.
