Abstract: An induction heater having inner and outer chamber cylinders connected in an air tight manner to a base and cover with an inner chamber being formed within the inner chamber cylinder and an outer chamber being formed between the inner and outer chamber cylinders, a heat exchange core disposed in the inner chamber, and an induction heater coil disposed in the outer chamber extending around the inner chamber cylinder. A flow path is provided from a cool air inlet in the base, along the outer chamber, into the inner chamber and through the inner chamber and core to a heated air outlet in the base in a counterflow direction relative to the flow along the outer chamber. The heater is especially well suited for use in convective soldering and rework apparatus.

Abstract: Mechanisms allow for execution of unsigned managed code graphic resource call in a closed system when such unsigned content is executing on the system. For example, a managed code graphic resource device is used between an application running unsigned content and a supervisor mode graphic resource device. A managed mode graphics device validates graphic resource calls made by the application. A managed mode graphics device manages resource calls by differentiating between calls that may be made directly to the supervisor mode graphics device, calls that may be pipelined for later action, and calls that may be made to an intermediate device.

Abstract: Mechanisms are disclosed that allow for the communication between closed computing systems and other computing systems. Gaming consoles, for instance, can use the present mechanisms to communicate with PCs, especially when unsigned content is sent from the PCs to the gaming consoles. The disclosed communication mechanism can have multiple channels to send information (which may include code and/or data associated with the unsigned content) from the PCs to the gaming consoles. Such information may be distributed over several channels on the communication mechanism. For instance, the communication mechanism can first send a subset of a set of information from a computing system to a closed computing system. Then, depending on the closed system resources, the remaining set of information can be sent to the closed system.
