SHANGHAI, April 24, 2017 /PRNewswire/ -- With the flagship exhibition held from April 4th to 7th this year in the Messe Frankfurt Exhibition Center, Prolight+Sound is the leading international trade show for audio-visual technologies, integrated systems and related services in the entertainment, hospitality and creative industries. This year, companies allied under the banner of Enping Microphone left a deep impression on visitors by presenting their high-quality, innovative products. Noted exhibitors included Enbao, Karsect and Sange, with 10 other manufacturers participating directly. Audio equipment manufacturers from the city of Enping in Guangdong Province, China's manufacturing heartland, united last year to form Enping Microphone, a brand alliance for the promotion of this impressive advanced electro-acoustic manufacturing hub. "We are committed to providing the best-value products and services to global consumers, by offering internationally competitive research and development, a worldwide supply chain and overseas service," said one Enping exhibitor. On the show, the Enping Electro-Acoustic Component Trade Association had their own booth at 4.1FOY25, showcasing the Microphone Economy to visitors, including projects like Enping's International Electro-acoustic Equipment and Microphone Trade Center, and briefing on its strategic partnerships with countries all over the world. "The Enping government continues to provide strong support to the famously outwards facing Enping region as an advanced manufacturing hub for microphones through ongoing investment in technology and infrastructure," said a senior official from the Enping Administration for Industry and Commerce. Enping city, the world's biggest manufacturing hub for electro-acoustic products, continues to expand into global market, and their brand recognition is growing among overseas consumers. According to figures from the association, in 2015 Enping's electro-acoustic industry total production volume exceeded more than 100,000,000 units, which accounted for more than 70% of China's export market share in the industry. The official also noted that around 100 manufacturers will join the Polight+Sound Shanghai later this year, to be held from October 11th to 14th 2017 in Shanghai New International Expo Center, and ensuring that its melody continues to resonate with quality around the world.

The present invention relates to a device and system for improving a laser light based imaging projection system, and especially to a device and system for controlling speckle contrast in laser light imaging projection systems according to a specific speckle reduction scheme. A device and system according to the present invention comprises at least on spatial light modulator with a programmable grating geometry on a reflective surface of the device. A series of control signals can then provide a static speckle pattern or a plurality uncorrelated speckle patterns. The device and system according to the present invention can utilize the programmable grating feature to decrease, or increase the speckle in whole images or parts of images being projected in the system.


The present invention relates to method and corresponding system for noise reduction in a Direct Current to Direct current converter (DC), and especially to a method and system for electronic noise reduction in an electric drive circuit for capacitive loads utilizing a charge pump.

The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material 12, for example silicone-gel is disposed onto a surface of a glass plate 10. The glass plate 10 can be moved with actuators towards a surface of a lens body 10. When the soft material element 12 is in contact with the surface of the lens body 12, this surface changes its optical feature.


The present invention comprises a system and a method thereof for identifying a specific Interdigitated Electrode pattern for piezoelectric actuators located around an aperture of a flexible lens body, wherein the Interdigitated Electrode configuration is configurable, when activated, to provide a specific definable bending force distribution, thereby providing a specific definable shaping of the flexible lens body, thereby providing specific definable optical characteristics of the flexible lens body.


The present invention relates to a low profile autofocus lens device (10), and especially to a low profile autofocus lens device that can be added into or added onto a stack of lenses (90-93) of an imaging system providing none to moderate increase of the overall height of the imaging system, and a method of manufacturing a stack of lenses (90-93) with the low profile autofocus lens device (10).
