    摘要: A thermal management structure to provide mechanical isolation and heat removal for a unpackaged semiconductor die mounted directly on a printed circuit board substrate. The thermal management structure sandwiches the unpackaged semiconductor die and substrate between two heat sink pieces which are rigidly mounted to the substrate, thereby mechanically isolating the unpackaged semiconductor die and preventing the die from being accidentally touched. The two heat sink pieces further compliantly thermally engage selected sites on the exposed face of the semiconductor die and the surface of the substrate to conductively remove heat away from the substrate. The thermal management structure may also thermally engage selected thermally conductive components within an end product to spread the heat more uniformly throughout the system.

    摘要: A computer systems which combines the capabilities of both notepad and notebook computers. The main housing includes an liquid crystal display display with a digitizer input to be used as the display in all modes and the input device when used with a stylus in notepad mode. Also located in the main housing are a floppy disk drive, a hard disk drive, an optional modem unit, batteries, and the electronics of the computer. The main housing contains a recessed portion for receiving a detachable keyboard. The keyboard includes a pivoting, mating extension which is received in the recess so that the keyboard is retained in the recess during storage conditions and in some cases of use, where the housing acts as a partial keyboard support to allow angling of the keyboard. The keyboard contains pivoting legs so that the keyboard can be used remotely from the main housing and yet be angled. The main housing contains a pivoting portion which can operate as a stand when the computer is being operated with the keyboard, so that the display is properly angled for viewing by the user. The pivoting portion can also be pivoted to a position generally parallel with the main housing, but having a portion extending past the housing to act as a handle.
