    摘要: System and method protects power drivers (10) and (12) that are used for airbag deployment. Temperature sensors (38) are strategically located on the integrated circuit (36) to detect temperature levels in power drivers (10) and (12). When the temperature in the power drivers (10) and (12) reaches a maximum level, an output is provided to logic block (26). Current detecting circuit (24) provides an output when the current flowing in power driver (10) reaches a desired level. Timing circuit (28) is activated when it receives the output from current detecting circuit (24). At the expiration of the time, timing circuit (28) provides an output to logic block (26). When logic block (26) receives both outputs, logic block (26) shuts drivers (10) and (12) down. When temperature sensors (38) detects that the temperature in integrated circuit (36) has reached a minimum level, logic block (26) reactivates drivers (10) and (12).

    摘要: A system and method for cooling are disclosed. The system for cooling includes an opening out of which a jet of coolant can flow, a target element, and a forcing device which causes the jet of coolant to flow out of the opening. The target element is positioned in front of the opening so that the jet of coolant, when flowing out of the opening, is directed toward the target element. The jet of coolant oscillates so that the jet of coolant sweeps across the target element and cools a variety of different locations along the target element.

    摘要: A system (5) and method are used for predicting and controlling the temperature of a semiconductor wafer (10) during a solder reflow process by controlling the operating profile of a solder reflow furnace (14). The emissivity of the surface of the wafer (10) is measured using an infrared device (11) prior to the solder reflow process. Using the measured emissivity value of the wafer (10), the peak temperature of the wafer (10) is predicted, and the operating profile of the solder reflow furnace (14) is adjusted accordingly to achieve a desired temperature profile of the wafer (10). A process for reflowing solder on a semiconductor wafer calculates a predicted peak temperature of a semiconductor wafer (10) and controls the actual temperature of the wafer (10) during a solder reflow process by controlling the operating profile of a solder reflow furnace (14).
