  • Patent number: 12233257
    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: 20210239646
    Abstract: The RGO (Reduced Graphene Oxide)-based bio sensor according to the present invention comprises: a source electrode and a drain electrode formed on a substrate; an RGO channel formed between the source electrode and the drain electrode; a PDMS (polydimethylsiloxane) chip supplying a reaction solution to the RGO channel; a passivation layer for sealing in order to prevent the reaction solution supplied through the PDMS chip from touching the source electrode and the drain electrode; and a gate electrode electrically connected to the reaction solution contacted to the RGO by being supplied through the PDMS chip. At this time, the passivation layer is formed with a SU-8 photoresistor, and the gate electrode is directly contacted to the reaction solution to thereby realize a liquid phase driving. The passivation layer is formed with SU-8 to allow supply of reaction solution through PDMS chip to be conveniently and stably realized. The operation is made possible at a gate voltage of ?1.0V˜1.

  • Patent number: 8110947
    Abstract: According to the present invention, provided is a watchdog system for Uninterruptible Power Supply (UPS), and auto recovery method using the same. In case the power supply path of UPS is switched from the normal power line to the bypass line, the UPS watchdog system of the present invention is firstly compulsively recovers again the power supply path to the normal power line for given times and, nevertheless, in case it is not recovered, the power is supplied through the bypass line. Accordingly, in case the power supply path is switched to the bypass line due to the temporary disorder of UPS, it can be rapidly recovered to the normal power path, so that the power supply by the UPS apparatus can be more stably performed.
