摘要： An apparatus includes a first power supply switch, a second power supply switch, and a control circuit. The first power supply switch includes a P-channel Metal Oxide Semiconductor Field Effect Transistor (PMOSFET) having a drain coupled to a first power rail to receive a first power voltage, a source coupled to an output node, and a gate to selectively turn on or off the PMOSFET to supply the first power voltage to the output node or isolate the first power rail. The second power supply switch receives a second power voltage and passes it to the output node if the second power voltage is present. The control circuit cooperates with the first power supply switch to control the gate voltage to turn on the PMOSFET if the first power voltage is present and the second power voltage is absent, and turn off the PMOSFET if the second power voltage is present.

摘要： Techniques to reduce light dissipation (e.g., light bleed) for electronic device assemblies. According to one embodiment, the techniques include forming a housing for a device from a plastic material. The housing defines an area of permissible light transmission from an interior portion of the housing through an exterior portion of the housing to provide one or more visual notifications for the device. The techniques further include forming a light dissipation layer from the plastic material proximate the area of permissible light transmission to inhibit light propagation through the housing outside the area of permissible light transmission.
