Abstract: This application relates to an active current compensation device which actively compensates for a noise occurring in a common mode in each of two or more high-current paths. In one aspect, the active current compensation device includes a sensing unit configured to generate an output signal corresponding to a common-mode noise current on each of the two or more high-current paths, and an amplification unit configured to amplify the output signal to generate an amplified current. The device may also include a compensation unit configured to generate a compensation current on the basis of the amplified current and allow the compensation current to flow to each of the two or more high-current paths, and a malfunction detection unit configured to detect a malfunction of the amplification unit. The malfunction detection unit and at least a portion of the amplification unit may be embedded in one integrated circuit (IC) chip.

Abstract: A telescopic apparatus is provided which can cause three or more cylindrical members to extend and contract smoothly without use of pneumatic pressure and hydraulic pressure.
A telescopic apparatus includes: a first to a third cylindrical member that are nested; screw shafts supported rotatably and respectively by the first and second cylindrical members; nuts mounted respectively on the second and third cylindrical members to be threadedly engaged with the screw shafts of the first and second cylindrical members; and a transmission configured to transmit the rotation of the screw shaft of the first cylindrical member to the screw shaft of the second cylindrical member and to be movable in an axial direction relative to the screw shaft of the first cylindrical member. The screw shafts of the first and second cylindrical members rotate at one time to cause the first to the third cylindrical member to extend and contract.-

Abstract: This application relates to an active compensating device. In one aspect, the active compensating device includes two or more high current paths through which a second current supplied by a second device is transmitted to a first device, and a sensing unit sensing the first current on the high current paths and generating an output signal corresponding to the first current. The device may also include an amplifying unit amplifying the output signal of the sensing unit to generate an amplified current and a compensating unit generating a compensation current based on the amplified current and allowing the compensation current to flow to each of the two or more high current paths. The device may further include a first anti-disturbance unit connected in parallel to output terminals of the sensing unit, and a second anti-disturbance unit connected in parallel to input terminals of the compensating unit.
