Abstract: A vibrator designed to be integrated into a portable electronic device as part of a haptic alert device has a linear electric motor that is coupled to actively drive a moveable weight in back-and-forth directions to produce the desired vibration. A lock mechanism has a restraining member that is biased into a lock position, which prevents the moveable weight from moving in the back-and-forth directions when the vibrator is inactive. Other embodiments are also described and claimed.

In one embodiment, a system includes one or more sensors coupled to an abuse detection sub-system for detecting the occurrence of an abuse event, wherein upon detecting an abuse event, a record of the abuse event is stored by the abuse detection sub-system. The system further provides a communication interface configured to provide a first mode of diagnostic communication and a second mode of non-diagnostic communication through a common input/output port. When using a diagnostic device, the diagnostic mode of communication may be enabled, thus allowing the diagnostic device to access consumer abuse event data stored by the abuse detection sub-system.

Abstract: An electronic audio host device has an audio accessory connector with multiple pins. An ultrasonic test signal source has an output coupled to a first pin of the connector. A programmable switch circuit couples a second or third pin of the connector, to a ground of the audio host device. A controller measures a signal on one of the pins of the connector while the test signal source is on, and compares the measured signal to a predetermined, stored signature. The signature is associated with one of several different accessory plug pin assignments for the connector, which can be configured using the programmable switch circuit. Other embodiments are also described and claimed.

Abstract: Whether an audio output amplifier of an electronic device is connected through an accessory connector to a headphone or a self powered audio device is determined by sensing the signature of the input power signal in an input power line to a voltage regulator circuit that ultimately powers the amplifier. The signature is sensed flowing through a sense circuit that is in series in the input power line while the amplifier outputs a high power, inaudible signal to the connected device. The signature is output to a controller. The controller indirectly determines from the signature, whether the impedance of the connected device is that of (1) a headphone (speaker) for which a headphone amplifier is selected to provide more power for a lower impedance load, or (2) a self powered output device (“line in” input) for which a “line out” amplifier and isolation resistor are selected to drive a high capacitive load.
