Speaker with dual diffuser
An improved loudspeaker is disclosed. The speaker includes at least one permanent magnet, an electromagnet and a diaphragm. The diaphragm has an inner portion (active portion) and an outer portion (stabilizing portion) that are both typically ring-shaped.

Described is an imaging component that utilizes two rolling shutter sensors for motion detection of objects and for depth mapping of objects within an effective field of view of the imaging component.

Method and system for mimicking human camera operation
The disclosure provides an approach for mimicking human camera operation with an autonomous camera system. In one embodiment, camera planning is formulated as a supervised regression problem in which an automatic broadcasting application receives one video input captured by a human-operated camera and another video input captured by a stationary camera with a wider field of view. The automatic broadcasting application extracts feature vectors and pan-tilt-zoom states from the stationary camera and the human-operated camera, respectively, and learns a regressor which takes as input such feature vectors and outputs pan-tilt-zoom settings predictive of what the human camera operator would choose. The automatic broadcasting application may then apply the learned regressor on newly captured video to obtain planned pan-tilt-zoom settings and control an autonomous camera to achieve the planned settings to record videos which resemble the work of a human operator in similar situations. |

Counterintuitively, this distortion compensation circuitry may involve increasing the power, such as the envelope tracking power supply.
