摘要： A method of responding to a thermal trip signal generated by a processor of a system having multiple processor nodes. If a processor overheats beyond a critical temperature, a temperature monitor receives the thermal trip signal, and turns off an enable signal to a voltage control module that control power to the processors. The temperature monitor also triggers a system reset. Upon reset, the temperature monitor ensures that all nodes, other than the node with the overheated processor, return to an operational state.

摘要： Methods and apparatuses for spectrally shaping mismatch errors in a multi-bit digital to analog converter (DAC). In an embodiment, a range signal is produced based on the digital input code. The range signal specifies which one of a plurality of ranges the digital input code is within. A density code is also produced, preferably, using a shuffling algorithm. The density code specifies a level within the range expressed by the range signal. The range signal and the density code are then combined to produce a plurality of sub-codes, a sum of the plurality of sub-codes equaling the digital input code.

摘要： A system for reducing the startup current demand of a computer system by providing clock signals at normal operating frequencies to a plurality of computer components in a staggered progression. The computer system includes a clock buffer having a plurality of outputs each for providing a clock signal to at least one computer component. During the startup of the computer system, the clock buffer provides at each output a clock signal at a normal operating frequency to each component in a staggered progression with the other outputs. Consequently, only one component (or component group) becomes operational at a time during the startup of the computer system. In one example, each output of the clock buffer is coupled to a memory module that includes multiple SDRAM chips. Because each memory module has a high initial current draw for initially charging its SDRAM cells, providing the clock signals at a normal operating frequency in a staggered progression provides a computer system where only one memory module is initially charging its memory cells at one time.

摘要： A chassis detection circuit for detecting and determining the chassis type. The chassis detection circuit detects structural differences of the chassis to determine chassis type. The chassis detection circuit provides a signal indicative of whether an electrically conductive surface such as a flange surface on a grounding clip is electrically contacting a grounded structure of a chassis such as a hook structure of a planar plate to which a circuit board is secured. The chassis detection circuit can be implemented in a computer system where the determined chassis type is used in environmental monitoring programs or operations. Also, where the chassis type is indicative of the computer system type, the determined computer system type may be used for operations requiring computer system type identification.

摘要： A system for calibrating a magnetic tape drive for accurate movement of a tape head or drive motor accommodates mechanical and manufacturing inaccuracies. Motion is corrected through sensing variations from desired position or speed through operation of the drive in one continuous motion. These values may then be processed or filtered to remove non-repeatable effects and thus achieve appropriate correction in operation. The values may be written to a ROM in tabular format correlating position correction values with track number or adjusting speed coefficients for use during operation. For the tape head, actual position values are sensed in one substantially continuous motion of the tape head through a move command for faster calibration.

摘要： A tape guide for a digital tape mini-cartridge providing decreased tape wander in a direction transverse to the intended path. The guide provides an increased area of tape having increased transverse stiffness without interfering with an adjacent drive wheel. In one embodiment, the guide is cylindrical and has a cylindrical cut-out to provide clearance for an adjacent cylindrical drive wheel. Preferably, the guide has top and bottom flanges. If a top flange of the guide is present, the cut-out continues through the top flange of the guide. The top flange of the guide may be relatively thin to fit below a top flange of the adjacent drive wheel. Alternatively, the top flange of the guide may have a larger cut-out to avoid interference with the top flange.

摘要： An optical beginning-of-tape detection device with automatic threshold adjustment. In a first embodiment, at two different locations on a tape, a comparator threshold is varied until the comparator switches states. The two locations are sufficiently far apart to guarantee that at least one measurement is not at the beginning-of-tape indication area. The greater of the two thresholds is used, with a predetermined offset for noise margin. In a second embodiment, the threshold is continuously adjusted through a diode across the comparator inputs. The threshold is initialized by moving the tape sufficiently far to guarantee that at some time during initialization the sensor is not at the beginning-of-tape indication area.
