Abstract: Systems and methods for soliton microcomb-based precision dimensional metrology via spectrally-resolved interferometry are described. In an embodiment, the system includes a dual-pumped soliton microcomb generator comprising a pump, a microresonator, and an auxiliary pump and that generates a single-soliton microcomb, an erbium-doped fiber amplifier that amplifies a C-band section of the soliton microcomb and a non-polarizing beam splitter that divides the soliton microcomb pulses into a reference arm pulse and a measurement arm pulse for an interferometer and recombines the reference arm pulse and the measurement arm pulse into a recombined beam upon their return.

Abstract: A power control device is provided for an aircraft. The power control device may include at least one first battery, a second battery having a lower power density and higher energy density than the at least one first battery, at least one lift motor connected, via a first electrical path, to the at least one first battery, a cruise motor connected, via a second electrical path, to the second battery, and a power control circuit configured to control the at least one first battery, the second battery, the at least one lift motor, and the cruise motor.

Abstract: A system for a vehicle may include a first battery pack diagnosis apparatus connected to a first battery pack, a second battery pack diagnosis apparatus connected to a second battery pack, a third battery pack diagnosis apparatus connected to a third battery pack, and a fourth battery pack diagnosis apparatus connected to a fourth battery pack. The first battery pack diagnosis apparatus may be configured to determine, based on a measured value of an integrated insulation resistance of an inverter terminal associated with the vehicle, whether a battery, of the first battery pack, the second battery pack, the third battery pack, or the fourth battery pack, is in a failure state, and based on a determination that the battery is in the failure state and based on individually measured insulation resistance of the first-fourth battery packs, determine a failure position of the battery.

Abstract: The present disclosure relates to a flight system and a failure responding method therefor. A flight system includes: a plurality of fuse boxes configured to control application of a voltage to at least one propulsion device; and an interlock control apparatus configured to control interlock lines between fuse boxes connected using the interlock lines among the fuse boxes to synchronize and control opening of the fuse boxes connected using the interlock lines.

Abstract: A battery support body may include a bracket extending in a front-rear direction and a shock absorber, which may extend in the front-rear direction and may be coupled to the bracket in a direction crossing the front-rear direction. At least a portion of the shock absorber may be provided in the form of foam.

Abstract: A wing frame includes a front wing beam extending in a left-right direction; a rear wing beam extending in the left-right direction and spaced rearward from the front wing beam, and a plurality of rib parts, each of which includes a middle rib coupled to a rear side of the front wing beam and a front side of the rear wing beam.

Abstract: A method of controlling an active seatbelt includes checking whether a seatbelt is fastened, collecting driving information from a sensor or driving assist/safety system installed in a vehicle, determining a safety state of the vehicle based on the driving information, checking whether an airbag is deployed, and outputting a motor control signal for restraint control of the seatbelt in response to the safety state when the airbag is not deployed.

Abstract: An active seat belt control apparatus is controlled according to a state of a vehicle. A control method for the active seat belt control apparatus includes: collecting, by a communication unit, state information about the vehicle; determining, by a controller, whether to activate a pulling operation of a seat belt using the collected state information; and activating the pulling operation of the seat belt using a motor.
