Abstract: A seat for a vehicle having a fold-and-dive function is proposed. When a seatback is rotated forwards and folded, a seat cushion is moved down, so the fold-and-dive function of the seat is realized. When a full-flat mode is realized by the reclining operation of the seatback, a rear end of the seat cushion is moved up, so a step between the seat cushion and the seatback can be significantly reduced or eliminated. Furthermore, a front link connecting a back cushion interlocking frame and a cushion fixing bracket to perform the fold-and-dive function is installed to have directivity where it is inclined rearwards, thus preventing a submarine phenomenon of the seat in the event of a forward collision.

Abstract: Instead of adopting a conventional method of using an average value to generate a clock for reading later data, an embodiment adopts using all count values stored from preamble data. If there are 10 preamble data bits, count values corresponding to the 10 bits are stored and used for a clock for reading later data. A clock count value of the first bit of the preamble is set as a reference count value and + or ? values compared to the reference value corresponding to the remaining data bits are stored in a memory as error values of the respective preamble bits. The error values are loaded according to data that is input later and a more accurate synchronization clock is generated. According to the data synchronization device and method, accuracy of data synchronization can be enhanced, and data loss when long-term data synchronization is performed can be prevented.

Abstract: In order to avoid the error that data is loaded according to a preset data rate cycle in a situation where a problem has occurred due to coil misalignment, a device and a method for transmitting data between coils according to an embodiment calculate a data reading timing margin on the basis of a fixed cycle that is a set system operation cycle, and read data at a time point resulting from adding the data reading timing margin to the fixed cycle.

Abstract: A multi-channel electric stimulator for a neural implant switches direct current according to nerve stimulation channels of different sequences of nerve stimulation. A direct current generator supplies direct current in response to nerve stimulation in the sequence of stimulation by controlling a nerve stimulation channel next in the sequence to stand by, with an electric current of the next nerve stimulation channel being modified into a direct current level, when nerve stimulation is performed using a nerve stimulation channel earlier in the sequence of stimulation. A biphasic current pulse generator generates a biphasic current pulse by switching the nerve stimulation channel-specific direct current supplied thereto. A controller controls a switching operation of the biphasic current pulse generator depending on a sequence of stimulation set according to the nerve stimulation channels. DAC switching noise induced by the occurrence of a biphasic current pulse is not transferred to the circuit.
