    Abstract: An apparatus for estimating blood pressure is provided. According to one embodiment, the apparatus for estimating blood pressure may include: a first sensor configured to obtain a pulse wave signal of a green wavelength from an object when the object is in contact with the first sensor; a second sensor configured to measure an external force applied to the second sensor while the first sensor is obtaining the pulse wave signal; and a processor configured to obtain an oscillometric envelope based on a direct current (DC) component of the pulse wave signal of the green wavelength and the external force, and estimate the blood pressure using the oscillometric envelope.

    Abstract: Provided is a cleaning device including a suction port; at least one sensor configured to sense at least one object; a driver configured to open or close the suction port; a memory storing at least one instruction; and a processor configured to execute the at least one instruction stored in the memory. The processor executes the at least one instruction to sense at least one object within an area to be cleaned by the cleaning device by controlling the at least one sensor, identify a relative location of the sensed at least one object with respect to the cleaning device, determine at least a partial area within an entire area of the suction port as an open/close target area, based on the identified relative location of the at least one object, and open or close the open/close target area by controlling the driver.

    Abstract: A method of manufacturing a three-dimensional field-effect transistor including an upper field-effect transistor stacked on a lower field-effect transistor. The method includes epitaxially growing source/drain regions of the lower field-effect effect transistor, growing a sacrificial layer on an upper surface of the source/drain regions, and epitaxially growing source/drain regions of the upper field-effect transistor on the sacrificial layer. The sacrificial layer is a seed layer for the source/drain regions of the upper field-effect transistor. The method also includes selectively etching the sacrificial layer to form a gap between the source/drain regions of the lower field-effect transistor and the source/drain regions of the upper field-effect transistor, and depositing an oxide layer in the gap.
