Abstract: An external AC power adaptor having an additional compartment for cooling. The adaptor has a housing that defines a first compartment having power circuitry for converting an AC input to a DC output and a second compartment that has an opening formed in the adaptor housing. A heat transfer plate is disposed between the first and second compartments.

Abstract: A method and system are provided for shielding electromagnetic interference (EMI). A first component and a second component are provided, whereby the two components are integrated in such a way that the second component, although only partially shielding itself, extends the EMI shielding ability of the first component. The second component can be an optical device drive (ODD) that provides only partial shielding when its tray is opened to insert an optical disk. However, because the ODD is integrated with the first component, which can be a gaming console, in such a way that no internal EMI generated by hardware internal to the first component can escape, the second component is used as an integral EMI shield of the first component.

Abstract: An appliance leakage current interrupter (ALCI) includes components for preventing sustained over-voltage and sustained over-current conditions. A current interruption threshold is inversely proportional to voltage supplied to the appliance. A microprocessor measures the voltage level of the incoming AC mains supply. The microprocessor is coupled to a sub-circuit for intentionally inducing a current mismatch between the two power lines monitored by the ALCI. Upon detecting an over-voltage of sufficient magnitude and duration, the microprocessor induces a current mismatch in the power lines, thereby causing the ALCI to interrupt power. A second current sensing transformer monitors one of the power lines. The microprocessor also receives the output of the second current sensing transformer. Upon detecting a current level exceeding a variable threshold, the microprocessor induces a current mismatch in the power lines and causes the ALCI to interrupt power.

Abstract: A computing device includes a housing with various electrical and/or mechanical components included therein. Disposed within the housing is a processor assembly that includes a fan. The fan is configured to draw air into the interior of the housing and force air heated by the internal components of the computing device from the interior of the housing. The fan has a diameter that is larger than the smallest dimension of the three orthogonal dimensions of the housing of the computing device and generates low levels of acoustic noise having a low frequency. Additionally, the processor assembly includes a support structure that supports the fan and reduces the effects of electromagnetic emissions generated by a processor of the processor assembly upon electrical devices adjacent to the computing device.
