Abstract: Provided is a cleaning device including a vacuum cleaner including a dust collector into which dirt and dust is collected, a docking station connected to the dust collector and having a long axis extending in a first direction, and the docking station includes a docking part coupled to the dust collector to remove dirt and dust collected in the dust collector, a sucking device sucking up the dirt and dust and inside air in the dust collector docked with the docking part through the docking part, and a circulation duct arranged for the air sucked up by the sucking device to be circulated to the docking part.

Abstract: The present invention provides a container having multiple compartments, the container comprising: a first container having a first interior volume; a second container having a bowl, a second interior volume defined by the bowl, and a lid, and inserted into and occupied a part of the first interior volume, wherein the second container includes a first engaging mean located along an inner edge of the bowl, and a second engaging mean located along an outer edge of the bowl; wherein the first engaging mean engages with a third engaging mean located along an edge of the lid, and wherein the second engaging mean engages with a fourth engaging mean located along an upper edge of the first container.

Abstract: The present invention provides a container comprising a cup; a protective member attached to a side wall of the cup, the protective member including: an outer side wall portion; an inner side wall portion contacting the side wall of the cup; a bottom end portion connecting between a bottom end of the outer side wall portion and a bottom end of the inner side wall portion; and a top end portion connecting between a top end of the outer side wall portion and a top end of the inner side wall portion, the top end portion having at least one hole; and an air gap formed between a side wall of the cup and the protective member, wherein the at least hole allows air to flow between the air gap and outside.

Abstract: Disclosed is a catheter, especially a catheter for denervation, having an improved head structure and its manufacturing method, which may have a small design, allow convenient production and ensure excellent reproduction. The catheter includes a cylinder member having a hollow formed therein, at least one electrode mounted to the cylinder member to generate heat, and a power supply wire printed on the cylinder member and connected to the electrode to give a power supply path for the electrode.

Abstract: An image sensor includes a pixel array, a controller, and a plurality of analog-to-digital converters. The pixel array includes a plurality of pixels coupled to column lines, respectively, and the plurality of pixels are configured to sense incident lights to generate analog signals through the column lines. The controller generate a conversion control signal that is configurable based on changes of at least one operational condition. The plurality of analog-to-digital converters are coupled to the column lines, respectively. The plurality of analog-to-digital converters perform a delta-sigma modulation and a digital filtering to convert the analog signals to digital signals. The plurality of analog-to-digital converters adjust a conversion gain internally in response to the conversion control signal.

Abstract: An analog-to-digital converter includes a modulator, a controller, and a digital filter. The modulator generates a modulated signal based on an analog signal. The controller generates a weight control signal. The digital filter includes a weight signal generator and a first integrator. The weight signal generator generates a weight signal based on the weight control signal. The first integrator generates a digital signal corresponding to the analog signal by integrating the weight signal in response to the modulated signal. The weight control signal corresponds to a type and an order of the digital filter.
