Abstract: A media editing device obtains a digital image, and a facial region of an individual in the digital image is identified by a facial region analyzer. A plurality of facial features of the facial region is identified by a facial feature identifier. A skin color of the facial region is determined, and eyebrow regions in the facial region are identified based on the facial features. Each of the eyebrow regions is partitioned into a plurality of segments, and a determination is made, for one or more of the segments, whether an area above or an area below the segment has a color matching the skin color. The segment is designated as a verified eyebrow region or as an overlapped region depending on whether the area above or the area below the segment has a color matching the skin color. A special effect is applied on the verified eyebrow region.

Abstract: A LED lighting system efficiently provides an operating voltage powering integrated circuits. A LED string has LEDs segregated into LED groups connected in series. A LED controller has channel nodes connected to the cathodes of the LED groups respectively, and an output node connected to a capacitor providing the operating voltage. The LED controller drains a channel current from a selected channel node among the channel node. The LED controller regulates the channel current to a channel target value corresponding to the selected channel node, and provides a portion of the channel current as a charging current to power and regulate the operating voltage.

The AC LED lamp has LED groups arranged in series between the rectified input voltage and the ground voltage. The power bank has a capacitor storing electric energy and a discharge switch coupled between the capacitor and the rectified input voltage. The integrated circuit has a path controller and a bank controller. The path controller controls conduction paths, each coupling a corresponding LED group to the group voltage. The bank controller turns on the discharge switch in response to a first path signal corresponding to a first conduction path, and turns off the discharge switch in response to a second path signal corresponding to a second conduction path. The first and second path signals are different from each other.

Abstract: An artificial retinal prosthesis system comprises an extraocular optical device and an intraocular retina chip. The extraocular optical device receives an external image, converts it into an optical pulse signal, and generates light energy. The intraocular retina chip receives the optical pulse signal from the extraocular optical device and produces an electric simulation signal. The intraocular retina chip includes a solar cell module receiving and converting the light energy into electric energy as a power source of the intraocular retina chip. The artificial retinal prosthesis system uses an optical modulation method to convert an image signal into an optical pulse signal, transmits the optical pulse signal into the eyeball, and decodes the optical pulse signal intraocularly. Thereby, the signal light intensity is improved without affect the contrast ratio.

Abstract: A wave power generation system includes a power generation component and a hydraulic component. The hydraulic component includes a cylinder and a piston. The cylinder connects to the power generation component. The cylinder has an accommodation space and a vent located in the middle section of the accommodation space such that the vent runs outside from the accommodation space. The accommodation space is used for accommodating a fluid. The piston is disposed in the accommodation space and is used for being guided by the accommodation space and sliding relative to the cylinder. Thereby, this drives the power generation component to convert mechanical energy into electrical energy, and to force the remaining air in the accommodation space and remaining air in the fluid to be discharged via the vent.
