US09078062B2 Driving of parametric loudspeakers
A parametric loudspeaker system comprises a pre-compensator (305) for generating a pre-compensated envelope signal by applying a pre-compensation to the input audio signal where the pre-compensation compensates for distortion of in-air demodulation of the modulated ultrasound signal. A pre-modulator (307) generates a complex base band signal generating a phase signal from the pre-compensated envelope signal using a predetermined function for determining a phase signal from an amplitude signal such that the corresponding complex signal has either suppressed negative or positive frequencies.

A modulator (309) quadrature modulates the complex base band signal on an ultrasonic quadrature carrier and an output circuit (311) drives the ultrasound transducer (301) from the modulated signal. The invention may allow effective yet low resource pre-compensation for a suppressed or single sideband modulated modulated ultrasound signal.

US09077919B2 Solid-state imaging device, imaging device, electronic equipment, A/D converter and A/D conversion method
In a reference signal comparison AD conversion scheme, a reference signal SLP_ADC and each of P and D phases of a pixel signal voltage Vx are compared.

A group III nitride semiconductor light-emitting element provided with: a semiconductor layer obtained by laminating a first semiconductor layer of a first conduction type, a light-emitting layer, and a second semiconductor layer of an opposite second conduction type; a first electrode connected to the first semiconductor layer; and a second electrode provided on the surface of the second semiconductor layer; the light-emitting layer including a first gallium indium nitride layer of a first indium composition, disposed on a side opposite the light extraction direction; a second gallium indium nitride layer of a second indium composition less than the first, disposed on the light extraction direction side from the first gallium indium nitride layer; and an intermediate layer containing a material of a smaller lattice constant than the materials constituting the first and second gallium indium nitride layers, provided between the first and second gallium indium nitride layers.
US09076911B2 Solar cell module and manufacturing method thereof
A solar cell module and a manufacturing method thereof are provided. A solar cell device including a light receiving surface and a non-light-receiving surface opposite to the light-receiving surface is provided. A first protective film and a cover plate are formed on the light-receiving surface, wherein the first protective film is located between the solar cell device and the cover plate. A thermal radiation material layer is screen printed and a second protective is formed on the non-light-receiving surface. A backplane is formed on the non-light-receiving surface, wherein the second protective film is located between the solar cell device and the backplane.
