Abstract: A startup boot cycle test system for testing a mobile multi-function device under test (DUT) that has a power manager and a main system processor is described. The system includes an external power source and a tester device. The external power source provides an input current to the power manager, which in turn provides a boot current, drawn from the input current, to the main system processor. The tester device connects to a test point in the DUT using a contact test probe to draw a margin current from the boot current. The resulting diminished boot current is used by the processor to boot. The tester device detects whether the processor successfully boots using the diminished boot current using a data input connector connected between the DUT and tester device. Other embodiments are also described and claimed.

Abstract: A hearing aid compatible portable electronic audio device is configured to automatically determine whether or not the device is being used by a hearing impaired user who is wearing a hearing aid, and select a mode of operation based on this determination. The device includes a proximity sensor and a magnetic field sensor. The proximity sensor is used to detect a change in distance of the device to the user's ear. The magnetic field sensor is used to detect a change in magnetic field caused by the device moving relative to the hearing aid. The device selects between a normal audio mode of operation and a hearing aid compatible mode of operation based on both the change in detected distance and the change in detected magnetic field. Other embodiments are also described and claimed.

Abstract: A mobile device that includes a motion sensor, multiple vibrators, and a motor speed determinator module. The motion sensor senses and records vibrations of the mobile device while the multiple vibrators are simultaneously running. The sensed vibrations are transmitted to the motor speed determinator module, which transfers the sensed vibrations into the frequency domain. The vibrations caused by each of the multiple vibrators are represented by peaks in the frequency representation. In one embodiment, the motor speed determinator module drives each vibrator such that the rotational speed and phase of each vibrator are equal or essentially equal. This is represented in the spectral representation of the frequency domain as the overlapping of each peak into a single peak.
