Abstract: An apparatus and a method for monitoring a bio-signal measuring condition are disclosed. The apparatus includes a bio-signal receiver configured to receive a bio-signal that is measured from a user, and a processor configured to extract any one or any combination of a waveform feature, a period feature, and an amplitude feature, from the received bio-signal, determine whether the extracted any one or any combination of the waveform feature, the period feature, and the amplitude feature are normal, using at least one predetermined determination reference corresponding to the extracted any one or any combination of the waveform feature, the period feature, and the amplitude features, and monitor a measuring condition of the received bio-signal, based on whether the extracted any one or any combination of the waveform feature, the period feature, and the amplitude feature are determined to be normal.

Abstract: A memory device includes a memory having a memory bank, a processor in memory (PIM) circuit, and control logic. The PIM circuit includes instruction memory storing at least one instruction provided from a host. The PIM circuit is configured to process an operation using data provided by the host or data read from the memory bank and to store at least one instruction provided by the host. The control logic is configured to decode a command/address received from the host to generate a decoding result and to perform a control operation so that one of i) a memory operation on the memory bank is performed and ii) the PIM circuit performs a processing operation, based on the decoding result. A counting value of a program counter instructing a position of the instruction memory is controlled in response to the command/address instructing the processing operation be performed.

Abstract: An apparatus for collecting a by-product, includes: a chamber provided with a gas inlet and a gas outlet and having an internal space; a heater disposed on the gas inlet side of the internal space within the chamber and varying a heating temperature in time series; a vortex forming member disposed around the heater; a plurality of first collecting members disposed below the heater; a second collecting member disposed below the first collecting member so that a plurality of second collecting members intersect each other; and a third collecting member disposed on the gas outlet side of the internal space within the chamber.

Abstract: One or more embodiments of the present disclosure may include: a transparent member; a housing coupled to the transparent member in a rotatable manner via a hinge portion, such that the housing is foldable in a designated direction with respect to the transparent member; a projector at least partially disposed in the housing; and an optical transferring member configured to guide light emitted from the projector to the transparent member when the housing is unfolded with respect to the transparent member in an unfolded state.

Abstract: A method of fabricating a semiconductor device includes forming an interlayer dielectric on a substrate, the interlayer dielectric including first and second openings respectively disposed in first and second regions formed separately in the substrate; forming a first conductive layer filling the first and second openings; etching the first conductive layer such that a bottom surface of the first opening is exposed and a portion of the first conductive layer in the second opening remains; and forming a second conductive layer filling the first opening and a portion of the second opening.
