Abstract: Systems and methods for refining search results in response to a user query are disclosed. A search term can comprise a queried data sets coupled with a fundamental operator (e.g., AND, OR, NOT, etc.), and one or more conditional operators that filter at least one of the data sets prior to execution of the fundamental operator in order to reduce the size of the result set. Post-processing conditional operators can be applied after execution of the fundamental operator to further filter the result set. According to one aspect, conditional operators comprise a mathematical operator and a numerical value.

Abstract: Systems and methods for vertically stacking integrated circuit (IC) modules on a motherboard to conserve motherboard space and reduce power consumption are disclosed. IC modules can comprise processor circuitry, memory elements, communication circuitry, etc. Pins on each IC module can be directly inserted into lower IC module or into a socket layer that couples the IC modules. Heat generated by the IC modules can be dissipated by inserting heat dissipation layers into the vertical stack, between IC modules, or by placing a heat-dissipating sleeve around the stack. The IC modules themselves and/or heat-generating regions therein may be misaligned on their respective socket layers to further facilitate dissipating heat. Module stacks are scalable in that a user may add memory and/or processor modules as desired to increase device capability.
