Digital video stabilization for multi-view systems
A system, method, and computer program product for digital stabilization of video data from cameras producing multiple simultaneous views, typically from rolling shutter type sensors, and without requiring a motion sensor. A first embodiment performs an estimation of the global transformation on a single view and uses this transformation for correcting other views. A second embodiment selects a distance at which a maximal number of scene points is located and considers only the motion vectors from these image areas for the global transformation. The global transformation estimate is improved by averaging images from several views and reducing stabilization when image conditions may cause incorrect stabilization. Intentional motion is identified confidently in multiple views. Local object distortion may be corrected using depth information. A third embodiment analyzes the depth of the scene and uses the depth information to perform stabilization for each of multiple depth layers separately. |

Automatic exposure control and illumination for head tracking
The subject technology provides embodiments for tracking a user's face/head (or another object) using one or more cameras provided by a computing device. Embodiments implement exposure sweeping based on an average intensity of a current scene to a target intensity for a given image. If a face is not detected, an exposure duration and/or gain may be adjusted and the face detection is performed again. Once the face is detected, an average intensity of a virtual bounding box surrounding the detected face is determined and exposure sweeping may be performed solely within the virtual bounding box to reach a target intensity. When the average intensity is within a predetermined threshold of the target intensity, the detected face may be at an optimal exposure. Embodiments also provide for switching to another camera(s) of the computing device when not detecting a face in the image upon performing a full exposure sweep. |

Semiconductor device incorporating a power on circuit
A semiconductor device which makes it possible to reduce a wasteful standby time at power-on is provided. In this semiconductor device, a reset of an internal circuit is canceled as described below. When a data signal stored in a storage section is at “0,” the reset is canceled by bringing an internal reset signal to the “H” level when a relatively short time has passed after the rising edge of a power on reset signal. When the data signal is at “1,” the reset is canceled by bringing the internal reset signal to the “H” level when a relatively long time has passed after the rising edge of the power on reset signal. Therefore, a wasteful standby time at power-on can be reduced by writing the data signal logically equivalent to the rise time of supply voltage to the storage section. |

Winding method for producing electric coils
A winding method for producing, for example, electric coils, wherein strand-shaped winding material (8) fed by means of a feeding device (7) is wound onto a carrier body having a non-circular cross-section by means of moving the winding material (8) and the carrier body relative to each other. Prior to placing the winding material (8) onto the surface to be wound, a force is applied onto the material transversely to the longitudinal extension thereof such that the strand-shaped winding material conform to the shape of the surface of the carrier body having a non-circular cross-section. |

Ecocharge system with layered graphene sheets for generating EMF from the earth's magnetic field to power electric vehicles
The earth's magnetic field has not been mined as a source of energy for electric vehicles. With average field strength of 0.5×10−4 Tesla around the world it is easy to understand why it has been overlooked. A disruptive technology is needed to mine the earth's magnetic field for powering electric vehicles. Such a technology, graphene, is now at an early stage of development with excellent properties in the form of high conductivity, low resistivity sheets that are durable, light weight, and low cost. Electrical properties of multiple sheets of graphene provide a significant multiplier to earth's weak magnetic field yielding a feasible source of ecologically clean power for electric vehicles. Graphene based EcoCharge systems can be mounted on a vehicles drive shaft and axles putting graphene in motion to mine the earth's magnetic field. Estimates show that EcoCharge can generate 15.1 kW at 60 mph while weighing only 10 oz. |

Distributed power harvesting systems using DC power sources
A photovoltaic panel with multiple photovoltaic sub-strings including serially-connected photovoltaic cells and having direct current (DC) outputs adapted for interconnection in parallel into a parallel-connected DC power source. A direct current (DC) power converter including input terminals and output terminals is adapted for coupling to the parallel-connected DC power source and for converting an input power received at the input terminals to an output power at the output terminals. The direct current (DC) power converter optionally has a control loop configured to set the input power received at the input terminals according to a previously determined criterion. The control loop may be adapted to receive a feedback signal from the input terminals for maximizing the input power. A bypass diode is typically connected in shunt across the input terminals of the converter. The bypass diode functions by passing current during a failure of any of the sub-strings and/or a partial shading of the sub-strings. The bypass diode may be a single bypass diode connected across the parallel-connected DC power source. The DC power converter may convert the input power at high current to the output power at a lower current. The output terminals may be connectible with wire cables to a load, and the DC power converter is configured to reduce energy loss through the wire cables to the load. |
