Abstract: A simulator of intelligent workstations at level 2 the OSI model for generating complete LAN frames for testing a system under test. The simulator includes a scripting facility that represents the actions of the human end-user at the client workstation. By providing a scripting facility, different complexions of a workload can be impressed upon the system under test without the need for human end-users nor the need for rebuilding the simulation tool. The simulator includes embedded protocol stacks allowing manipulation of the simulated LAN frames. The simulator also includes one or more embedded protocol application modules for emulating actions of an application, e.g., web browser, and enabling the handling of dynamic, application-related events.

Abstract: A housed integrated circuit unit package is provided with a heat sink for removal and dissipation of heat from electronic circuits housed in packages. The heat sink, mounted on an outer surface of the package, includes a plurality of pins secured at one end with a retainer and flared out at the other end into a starburst or bouquet configuration, the pins being in the form of rods selected from solid cylinders and tubes. The bottom of the retainer-bound end is coated with a securing substance, such as solder or a heat-conducting adhesive, which is planarized to facilitate positioning of the heat sink on the package. The heat sink is secured to the package by means of solder or a heat-conducting adhesive. The heat sink is produced by securing a plurality of elongated rods by retainers placed at intervals corresponding to a height of the heat sink, cutting off said rods adjacent to one side of the retainer, and flaring the rods at the other free end of the cut-off rods into a starburst-like configuration.
