Abstract: The present invention is related to a novel positive electrode active material for lithium-ion battery. The positive electrode active material is expressed by the following formula: Li1.2NixMn0.8-x-yZnyO2, wherein x and y satisfy 0<x?0.8 and 0<y?0.1. In addition, the present invention provides a method of manufacturing the positive electrode active material. The present invention further provides a lithium-ion battery which uses said positive electrode active material.

Abstract: A method is provided. The method includes determining a first bump map indicative of a first set of positions of bumps. The method includes determining, based upon the first bump map, a first plurality of bump densities associated with a plurality of regions of the first bump map. The method includes smoothing the first plurality of bump densities to determine a second plurality of bump densities associated with the plurality of regions of the first bump map. The method includes determining, based upon the second plurality of bump densities, a second bump map indicative of the first set of positions of the bumps and a set of sizes of the bumps.

Abstract: A device includes a main body and at least one actuating and sensing module. A length of the main body is 35˜55 mm. A width of the main body is 25˜30 mm. A height of the main body is 9˜13 mm. The actuating and sensing module is disposed in the main body. The actuating and sensing module includes a carrier, at least one sensor, at least one actuating device, a driving and transmitting controller and a battery. The sensor, the actuating device, the driving and transmitting controller and the battery are disposed on the carrier. The actuating device is disposed on one side of the sensor. The actuating device includes at least one guiding channel. The actuating device is enabled to transport fluid to flow toward the sensor through the guiding channel so as to make the fluid measured by the sensor.

Abstract: A brewing and extracting apparatus comprises an extracting cup, an eccentric filter and a stirrer configured inside the extracting cup, wherein the stirrer is driven by a motor so as to generate whirlpool currents from soaking liquid injected into the extracting cup by rotating the stirrer. The eccentric filter has a container placed within the extracting cup and soaked in the soaking liquid wherein the container is on a position deviating from the center of the whirlpool currents so as to bring contents of tea-leaves in the container up increasingly and dissolve the contents into liquid through the whirlpool currents.
