Yun-Chong Hwang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9690519
    Abstract: Provided are a solid state drive (SSD) card and an electronic system including the same. The electronic system includes a main board to which an input device and an output device are connected. A central processing unit (CPU) and a platform hub (PH) are provided on the main board. The PH is electrically connected to a hybrid interface socket. The hybrid interface socket includes a secure digital (SD) card interface and a non-SD card interface. When the SSD card and the electronic system including the same are used, a storage capacity may be conveniently upgraded to a higher capacity. Also, since the hybrid interface socket is provided in place of a conventional SD card socket, additional space is not required and thus space may be efficiently used.

  • Patent number: 5663855
    Abstract: The invention relates to a magnetic actuator latching apparatus in a hard disk drive, for maintaining the actuator of the hard disk drive in a parking zone while the actuator is not in operation. A magnetic actuator latching apparatus of a hard disk drive comprises a latching screw installed at the voice coil end of an actuator, which is easily latched by a permanent magnet, in order that a head of the actuator is positioned in a parking zone of a disk so that data recorded on a disk can be safely protected while said hard disk drive is not in operation. The permanent magnet attracts the latching screw through a magnetic force and then enables the head of the actuator to be positioned on the parking zone, upon the power-off of said hard disk drive. A damper, which houses the permanent magnet, buffers a shock or an impact resulting from being contacted with the latching screw. A latch assembly has a damper inserting part for receiving the damper and a plate extending from the damper inserting part.
