  • Publication number: 20220016417
    Abstract: An implantable lead having adjustable electrode locations and a system for controlling the same. The implantable lead may include a plurality of first electrodes exposed and formed at an upper part of a main body at given intervals, a plurality of second electrodes coupled to a stepped lower part of the main body and configured to deliver a stimulus signal to a core area into which the lead is inserted, and a plurality of signal lines embedded in the main body and configured to connect the first electrodes and the second electrodes in a one-to-one manner. In this case, a slot for coupling and up and down movement of the second electrodes may be formed in the lower part. As the second electrodes are individually moved along the slot by an external force acting on the signal lines, locations of the second electrodes in the lower part may be adjusted.

  • Publication number: 20220016590
    Abstract: Proposed is a carbon dioxide reforming (CDR) reactor having a multilayered catalyst layer arrangement for preventing catalyst deactivation, wherein, in the reactor in which a CDR reaction for reacting methane (CH4) with carbon dioxide (CO2) to reform the methane into a synthesis gas including carbon monoxide (CO) and hydrogen (H2) is performed, in order to prevent a case where an endothermic reaction between a catalyst and heated reactant gas supplied to the reactor gradually causes the temperature of the reactant gas to decrease and the catalyst is deactivated by cokes generated due to the decrease in temperature of the reactant gas, CDR catalysts in the reactor are arranged in multiple layers in a multilayered structure to allow the reactant gas temperature that has decreased due to the endothermic reaction to be restored in spaces between the catalyst layers.
