Abstract: A showerhead system with a normally open, temperature controlled first water valve coupled between a hot water source supply inlet and a purge outlet. The first water valve is configured to move from its normally open position to a closed position to restrict water passing from the hot water source supply inlet to the purge outlet when the temperature controlled water valve reaches a predetermined temperature. In a first mode, the first water valve purges water from the hot water source supply inlet through the purge outlet until the thermal actuator reaches the predetermined temperature. In a second mode, the first water valve blocks water entering the first water valve from passing through the purge outlet toward the showerhead outlet. In an optional third mode, a normally closed, manual second water valve is open and passes water through the showerhead outlet.

Abstract: Approaches in accordance with various embodiments provide for the management of system event data in a computing device. In particular, various embodiments provide an intelligent persistent buffer for system event log (SEL) messages. A SEL message can be generated by system BIOS on a computing device, which can send this message over an appropriate interface to a target recipient, such as the BMC. Instead of being received directly to the BMC, however, the SEL message can be received to a logic device, such as a CPLD, that is able to analyze the message, determine that the message relates to an important system event, and can cause this message to be stored to a persistent buffer. The BMC can then subsequently request the buffered SEL message from the logic device to take an appropriate action.

Abstract: Systems and methods of filtering particulate matter from a fluid are provided. In one exemplary embodiment, a system for filtering particulate matter having suspended particles, organic contaminants, and microorganisms from a fluid comprises a main filter assembly having an activated carbon block disposed therein. The carbon block has distributed pores with a diameter of less than one micron. Further, the carbon block is operable to filter all of the particulate matter having a diameter or a non-spherical width of at least 0.45 microns from the fluid, and adsorb the particulate matter having a diameter or a non-spherical width of at least 0.003 microns from the fluid.

Abstract: When a computer boots up, a Basic Input/Output System (BIOS) configures system memory to have a crash memory area within the system address map, which can be used by a processor to dump crash memory data. When an error event occurs, the processor can initiate a dump to the crash memory area. Any desired data can be placed into the crash memory area, but typical data can include a state of registers in the processor. The processor then sets a flag, such as an external pin, indicating that the crash memory data is ready to be read. The flag can be read by a secure processor, which then reads the crash memory area at normal memory access speeds using the system bus. For example, the secure processor can access the crash memory area using Direct Memory Access (DMA) reads over a PCIe system bus.

Abstract: Systems and methods for an integrated reliability, availability, and serviceability (RAS) state machine are provided. Handling of RAS events by the Basic Input Output System (BIOS) of an integrated circuit device can result in lost processing time on the processing cores of a multi-core processor resulting from numerous system management interrupts generated by the BIOS. To reduce lost processing time, a dedicated state machine can execute instructions to handle RAS events independently of the BIOS and minimize the number of system management interrupts.

Abstract: A method and apparatus for storing and reading an entry having one of a plurality of entry types and storing order information about stored entries, using a single addressable storage array. An index pipe maintains first in, first out order of the entries stored in the addressable storage array. Stages in the index pipe store a value representing the address of the stored entry in the storage array, the type of the stored entry, and the validity of the stored entry. Additional control logic implements order rules between entry types.

Abstract: An automated film encoding and decoding system for bringing photographic film from the state of exposure to subject matter through all of the processes required to produce finished photos and package the same. The system includes an encoder coordinately operative with a camera for the placement of a human and machine readable code on the film the decoder capable of reading the code for the control of production-processing equipment in laboratories provided with such equipment. The human readability of the code accommodates production-processing of the film by attendant personnel and also allows for quality control check of automated production-processisng equipment. The encoding includes film frame identification information, subject matter information and registration mark information all of which may be utilized on a single exposure situation.
