摘要： Electronic devices may provide microphone bias voltages to accessories. The accessories may include circuitry powered from the microphone bias voltages. The output impedances and the voltages of the microphone bias voltages may be adjusted during operation of the electronic devices. An electronic device may provide a bias voltage to an accessory, may lower the output impedance of the bias voltage, and may increase the voltage of the bias voltage during operation of the electronic device. Accessories that received bias voltages with lowered impedances or raised voltage levels may exhibit greater tolerance to faults such as moisture-based shorts and may be able to continue operating even in the presence of some faults.

摘要： Solar power tracking techniques are described herein. In one aspect of the invention, a solar power tracking apparatus includes, but is not limited to, a voltage converter and a controller coupled to the voltage converter. The voltage converter includes an input capable of being coupled to a solar power source and an output capable of being coupled to an electronic load, such as, for example, a portable electronic device. The voltage converter is configured to monitor or detect an amount of power drawn by the electronic load at the output of the voltage converter. In response to the monitored power drawn, the controller is configured to control the voltage converter to reduce amount of power to be drawn subsequently if the monitored amount of power exceeds a predetermined threshold. As a result, the output voltage from the solar power source is maintained within a predetermined range. Other methods and apparatuses are also described.

摘要： A packaging technique for electronic devices includes wafer fabrication of contacts on the bottom surface of the substrate underneath the active circuit. Inherently reliable contacts suitable for a variety of devices can be formed, via a simple fabrication process, with good wafer packing density. In one embodiment, a trench is formed in the top surface of a substrate parallel to the edge of its electronic circuit. A gold wire extends from a connection point within the circuit into the trench. The gold wire may run over an insulating layer that ends part way through the trench. After epoxy encapsulating the top of the substrate, it is back thinned to expose the bottom surface of the gold wire. Either the back thinning is selective so as to form a substrate standoff, or an epoxy standoff is applied to the bottom of the substrate. A solderable wire runs onto the standoff from the gold wire exposed on the protrusion, possibly over another insulation layer. If an insulative substrate is used, the insulation layers may be optional. Sawing separates the electronic devices and completes their fabrication, without a subsequent assembly step. In another embodiment, the trench in which the gold wires and the solderable wires connect is formed from the bottom of the substrate after it has been epoxy encapsulated. Optionally, the bottom surface of the substrate of the finished device drops down to be co-planar with the contact bottom surfaces, so as to conduct heat out of the device.
