Patent number: 7017258Abstract: A system for mounting heatsinks, in particular, high-mass heatsinks, on printed circuit boards, such as motherboards. The mounting system includes a backplate, disposed beneath the motherboard, with pins protruding up through the motherboard, and a linkage assembly, which is fixably attached to a base portion of a heatsink assembly. The linkage assembly includes scoops, for grasping the pins during engagement, and a ratcheting system, for compressing the heatsink and thermal interface material onto the package. The mounting system is designed to effectively distribute the heatsink weight, as well as the forces caused by chronic and dynamic stresses, through, rather than upon the motherboard, such as to a chassis. The mounting system thus alleviates stress cracks, component pullout, solderball stress, and other damaging conditions to the motherboard. The mounting system may be engaged and disengaged without the use of tools.Type: GrantFiled: January 26, 2004Date of Patent: March 28, 2006Assignee: Intel CorporationInventors: Michael Z.

Patent number: 6902377Abstract: A fan impeller is part of a fan assembly designed to maximize both intake and expelled air during use. The fan impeller employs a distinct airfoil shape for the fan blades to substantially move the ambient air. A low constant blade angle and overlapping blades are employed to improve the blade lift and consequent mass flow and exit pressure. The blade stall is eliminated, as evidenced by a smoothened fan curve, for more efficient operation. The blade sweep angle is optimally arranged to control radial flow characteristics of the ambient air. Housing sidewalls are removed from the fan assembly to remove parasitic drag and improve the motion of air passing through the fan.Type: GrantFiled: April 21, 2003Date of Patent: June 7, 2005Assignee: Intel CorporationInventor: Michael T.

Patent number: 6879489Abstract: A system in which a voltage regulator controls the die voltage rather than the socket voltage of a microprocessor is disclosed. The voltage regulator's response time is decreased due to the larger transient of the die voltage, relative to the socket voltage. The variation in socket resistance is no longer a factor affecting voltage and power loss margins. The system is implemented with minimal cost, as the die voltage is already available for use during testing.Type: GrantFiled: February 6, 2003Date of Patent: April 12, 2005Assignee: Intel CorporationInventor: Henry W. Koertzen

Patent number: 6879138Abstract: A buck converter is disclosed which prevents a voltage drop below a desired voltage when a load change occurs. The buck converter generates an override signal to turn on one or more switch devices in the circuitry. The effect of the override signal is to provide a sudden increase in the current supplied to a load, preventing the output voltage from dropping below the predetermined level. Sensing circuitry within the buck converter detects a voltage drop at the load, causing the override signal to be generated. The override signal may be a continuous signal or a one-shot pulse. Additional current sensing circuitry and the switch history of the buck converter determines the duration of the override signal for one embodiment and the number of switches activated within the buck converter.Type: GrantFiled: October 18, 2002Date of Patent: April 12, 2005Assignee: Intel CorporationInventors: James S. Dinh, Robert D. Wickersham

Patent number: 6854372Abstract: A miter saw is adapted for performing lengthwise, or rip, operations on a work piece such as wood. A back support arm is positioned off-center such that the work piece can be inserted under the miter saw substantially parallel to the blade. An arcuate aperture in the back support arm ensures that bevel adjustment properly aligns the blade with the blade slot during bevel cuts. An adjustable rail enables the work piece to be positioned in either a normal position, for crosswise cuts, or an orthogonal position, for lengthwise cuts. A toggle switch overrides the on/off switch on the handle, useful when the work piece is fed from behind. Two separate sleeves cover the blade, assuring safety during operation for both lengthwise and crosswise cuts. A tensioning board feed roller holds the work piece in place during lengthwise cutting.Type: GrantFiled: June 4, 2002Date of Patent: February 15, 2005Inventor: William Jefferson Anthony

Patent number: 6771099Abstract: A synchronizer eliminates metastability due to violation of either the setup time or the hold time of a circuit. The input of a first flip-flop (12a) is tied to a constant logic level (VDD or ground). The first flip-flop receives an asynchronous signal into the reset (preset or clear) input of the flip-flop. No violation of the setup or hold times of the flip-flop can occur. The second flip-flop (12c) receives the output of the first flip-flop as its clock input. The second flip-flop (12c) is configured as a toggler. The second flip-flop produces a synchronized partial signal (18a) of the original asynchronous signal (10a). Third and fourth flip-flops (12b,12d) may similarly be configured to produce a second synchronized partial signal (18b) of the asynchronous signal recovery and may prevent runt pulses from being received by the flip-flops.Type: GrantFiled: February 12, 2003Date of Patent: August 3, 2004Inventors: Jose Alberto Cavazos, Robert Maurise Simle

Patent number: 6710266Abstract: A technique to simultaneously reduce high-frequency insertion loss and cross-talk for a multi-layered add-in card is disclosed. The technique is based on selective removal of ground and power planes beneath the edge fingers. This selective removal of power and ground planes removes excess capacitance at the edge fingers, lowering the insertion loss at high frequencies, while maintaining an impedance match with an associated connector. Simultaneously, the leftover metallic ground/power plane provides electromagnetic shielding and thus reduces the cross-talk between the differential pairs. Optimum performance of the connector with minimized insertion loss and cross-talk can be obtained for high-speed analog and digital applications.Type: GrantFiled: July 26, 2002Date of Patent: March 23, 2004Assignee: Intel CorporationInventors: Jason A. Mix, Yun Ling, Alok Tripathi, Kent E. Mallory
