  • Patent number: 8489217
    Abstract: A mechanism is provided for minimizing reliability problems in a three-dimensional (3D) integrated circuit. A set of sensors are interrogated for current data. A direction of force and a magnitude of the force are determined based on the current data for each sensor in the set of sensors for each of one or more directions between the sensor and at least one neighboring sensor thereby forming a set of forces. Each of the set of forces is used to identify one or more points of stress that are at or above the predetermined force threshold. Responsive to identifying at least one point of stress that is at or above the predetermined force threshold, one or more temperature actuation actions are initiated in order to reduce at least one point of stress in the region where the at least one point of stress is identified.

  • Patent number: 8139355
    Abstract: One embodiment of the present invention provides a computer memory system that includes at least one DIMM connector having a DIMM socket for releasably receiving a terminal edge of a DIMM. A metallic or otherwise highly heat-conductive base is secured to the DIMM connector. A pair of heat spreaders is secured to the base on opposing sides of the DIMM socket. Each heat spreader includes a DIMM-engagement portion spaced from the base. The heat spreaders are nondestructively moveable between an open position spaced apart for receiving the DIMM between the heat spreaders and a closed position for thermally engaging opposing faces of the DIMM. The heat spreaders provide a continuous thermally-conductive pathway between the DIMM-engagement portion and the base. Heatsink fins extend laterally from the base to provide cooling.

  • Publication number: 20090147827
    Abstract: Implementing spread spectrum using digital signal processing techniques. An incoming clock signal is received and sampled using a programmable sampling mechanism to generate a plurality of signal data points included in a sampled signal. The sampled signal is conditioned using a programmable signal conditioning mechanism capable of performing at least one of: reducing a cycle to cycle jitter of the sampled signal; or adjusting the sampled signal to a base frequency. The signal data points are processed and spread across a band of frequencies using a programmable digital signal processor to adjust at least one of: (a) an amplitude, (b) a phase shift, or (c) a frequency shift; for each of a plurality of respective signal data points at a plurality of corresponding frequencies in the band of frequencies. An output waveform is constructed from the processed and spread signal data points, wherein the output waveform constitutes a clock output signal.

  • Patent number: 5027254
    Abstract: A side-by-side double row of electronics packages plug into a common backplane. Cooling air flows in an (upside down) omega-shaped path turning into one row of packages, flowing through that row, turning through an air-moving device into a plenum chamber, then turning into the second row of packages, and out of the second row turning again to an outlet.
