  • Publication number: 20190302400
    Abstract: One embodiment of the invention provides an optical lens including a first lens group with at least two lenses, a second lens group with at least two lenses, and a parting line located between the first lens group and the second lens group. Each of the lenses of the first and the second lens groups is associated with a respective distance, the respective distance is a distance value measured along an optical axis between two focal points of two end points of an image circle diameter formed at an image plane of the optical lens, under the condition that an optical center of one of the lenses is shifted a distance away from the optical axis. The two lenses with the two largest distance values among all lenses are disposed on the same side of the parting line.

  • Publication number: 20190279346
    Abstract: Certain embodiments involve blending images using neural networks to automatically generate alignment or photometric adjustments that control image blending operations. For instance, a foreground image and a background image data are provided to an adjustment-prediction network that has been trained, using a reward network, to compute alignment or photometric adjustments that optimize blending reward scores. An adjustment action (e.g., an alignment or photometric adjustment) is computed by applying the adjustment-prediction network to the foreground image and the background image data. A target background region is extracted from the background image data by applying the adjustment action to the background image data. The target background region is blended with the foreground image, and the resultant blended image is outputted.

  • Publication number: 20180301976
    Abstract: A power supply includes a transformer winding, a switching circuit, a controller and a filter circuit. The transformer winding is configured to provide a first voltage. The switching circuit is coupled to the transformer winding and includes a first and a second switching unit. On the condition that the power supply is operated under a standby mode, the controller controls the first and the second switching units to provide a discharging path between two terminals of the transformer winding. On the condition that the power supply is operated under an operating mode, the controller controls the switching circuit such that the switching circuit provides a second voltage according to the first voltage. The filter circuit is coupled to the switching circuit and configured to filter the second voltage to provide an output voltage.

  • Patent number: 9352331
    Abstract: A high capacity magnetic filter separates diamagnetic and/or paramagnetic substances from fluid streams. Diamagnetic solid substances are magnetized under an external magnetic field through coordinated interaction of diamagnetic solid substances with an inducement paramagnetic material (IPM). The magnetic filter serves as a separation zone created by the presence of IPM and magnets that are shielded from the IPM by non-magnetic sleeves or partitions. The IPM in the void volume between the magnets affords large surface area onto which diamagnetic and paramagnetic materials can contact and be attracted to. The relative position and distance of the magnetic source, such a magnetic bar or electromagnet, to the solid mixture of diamagnetic and IPM are adjusted to induce sufficiently strong magnetism in the diamagnetic solids which causes the diamagnetic solids to be attracted by the magnetic field as well. Both diamagnetic and paramagnetic substances can be removed from a liquid or gas.

  • Publication number: 20140111938
    Abstract: A metal cooling plate functioning includes a plurality of through cooling patterns. Each cooling pattern includes a ventilation through hole and two ā€œVā€-shaped annular grooves, each annular groove surrounding the outside the ventilation through hole. Each side of the cooling plate defines the ā€œVā€-shaped annular groove, where the annular grooves being paired are directly opposing each other. Areas of the metal cooling plate directly between respective bottoms of the opposing grooves form an annular plastic zone in which electrical resistance is higher than a resistance of the metal base at all other areas.
