Abstract: A heat sink retention device for retaining a heat sink, including a spring, proximate an electronic device in a circuit board. The device includes a first component configured to be attached to a circuit board, and a second component configured to be adjustably attached to the first component, and including an opening configured to retain a portion of a spring of a heat sink. When the first and second components are attached together and the first component is attached to the circuit board, the heat sink retention device is adapted to allow application of a force on the spring in order to retain the heat sink proximate an electronic device mounted on the circuit board.

Abstract: An land grid array (LGA) or hybrid land grid array (HLGA) includes a socket housing and a plurality of electrical contacts. The socket housing is made of a first material that defines a first dielectric constant. The plurality of electrical contacts extends through the socket housing to electrically couple a printed circuit board on a first side of the socket housing to a processor on a second side of the socket housing. A coating of a second material that defines a second dielectric constant that is higher than the first dielectric constant covers surfaces of a subset of the plurality of electrical contacts.

Abstract: Techniques are provided to convert utility power having an unstable utility frequency into supply power having a stable frequency, which can be distributed and utilized as a system reference. For example, a system comprises a power generator and a power distribution system. The power generator is configured to convert utility power having an unstable utility frequency to supply power having a stable frequency component. The power distribution system is coupled to an output of the power generator, and is configured to distribute the supply power having the stable frequency component to at least one power consumer which is configured to utilize the stable frequency component of the supply power as a reference frequency.

Abstract: A heat sink to selectively dissipate heat from a plurality of heat-generating components. The heat sink includes a plurality of heat pipes, and a base plate configured to locate at least one of the plurality of heat pipes proximate each of the plurality of heat-generating components. The heat sink also includes a plurality of sets of fins operable to dissipate heat generated by the heat-generating components, and a plurality of sets of louvers, wherein each of the plurality of sets of louvers is associated with one of the plurality of sets of fins and is operable to open to selectively allow airflow from outside the heat sink to dissipate heat from one of the plurality of sets of fins.

Abstract: A heat pipe system, method, and heat sink system to enhance heat transfer from a heat-generating component. The method includes generating heat with the heat-generating component. The method also includes transferring at least a portion of the heat to at least a portion of a volatile fluid within one or more heat pipes. The method further includes modifying, dynamically, an active heat transfer region of the one or more heat pipes, thereby dynamically modulating heat transfer from the heat-generating component through the one or more heat pipes.
