Abstract: There is provided an air blower assembly removing foreign objects, or the like, attached to an object to be cleaned by blowing high pressure air. The air blower assembly includes: a frame; and a nozzle fixed to the frame and having one end to be connected to the blower to remove foreign objects by air blowing to the other end, wherein the nozzle is an elastic body that moves freely by air blowing.

Abstract: Disclosed are an apparatus for cleaning a camera module, including: a housing in which a camera module, the object to be cleaned, is received, an opening/closing unit that opens/closes the housing, and an air suction unit that is connected to the housing and discharges air in the housing to the outside, and a method for cleaning the camera module. The apparatus and the method for cleaning the camera module remove the fine foreign substances of the camera in such a manner that the instantaneous velocity of air supplied to the camera module is increased by receiving the camera module, the object to be cleaned, in a negative pressure state, and breaking the negative pressure state, thereby making it possible to clean the complicated and narrow inside of the camera module, and generates vibration to the supplied air using the opening/closing unit that is rapidly and repeatedly opened/closed, thereby making it possible to more effectively remove the fine foreign substances.

Abstract: A data storage system includes data storage including at least one data storage disk driven by a spindle motor and a control circuit coupled to the data storage and configured to be coupled to a main power source and a backup power source. The control circuit is configured to detect failure of the main power source, to responsively write data to the data storage while powered by the backup power source, and to subsequently recharge the backup power source using the spindle motor. The control circuit may be configured to further write data to the data storage using the recharged backup power source. The data storage system may further include a head configured to read and/or write data to or from the at least one data storage disk, and the control circuit may be configured to park the head using the recharged backup power source.

Abstract: A main controller for use within a data storage device including a first data storage device and a second data storage device is disclosed. The controller includes a memory configured to store a plurality of protocol program data, and a processor configured to receive a host control signal from a host defining a primary operation, and to execute protocol program data selected from the plurality of protocol program data to define a first data communication protocol in accordance with the received host control signal. The processor is further configured to electrically store data in the first data storage device or magnetically store the data in the second data storage device during a secondary operation associated with the first operation, wherein the data is communicated from the processor to the first data storage device or the second data storage device during the secondary operation using a second.
