  • Patent number: 10305446
    Abstract: A piezoelectric oscillator, and method of making the same, includes an oscillation substrate comprising an oscillating part and a surrounding part, wherein the surrounding part is thinner than the oscillating part, and oscillating electrodes disposed on an upper surface and a lower surface of the oscillating part. The oscillation substrate is configured according to H=400.59×S+1.75±1.5, wherein H=100×(T2/T1) and S=T2/(L1?L2), wherein L1 represents an entire length of the oscillation substrate, L2 represents a length of the oscillating part, T1 represents a thickness of the oscillating part, and T2 represents a step height between the oscillating part and the surrounding part.

  • Patent number: 9336398
    Abstract: An apparatus and method for manifesting an event to verify the security of a mobile application are provided. The apparatus for manifesting an event to verify the security of a mobile application includes a tester application production unit, a tester application execution unit, and a tester application daemon execution unit. The tester application production unit produces a tester application for testing an application to be tested based on application information which is extracted from the application to be tested. The tester application execution unit executes the application to be tested by manifesting an event included in the extracted application information, and extracts a user view object output to a screen of a smart device when the application to be tested is executed. The tester application daemon execution unit generates a touch event based on the extracted user view object, and performs a screen change.

  • Patent number: 8644248
    Abstract: A terminal having a stream control transmission protocol (SCTP)-based handover function and an SCTP-based handover method, the terminal including: a session management unit to initiate an SCTP session with a second terminal; a link layer information collection unit to store beacon signals in a link layer state information database; a signal intensity extraction unit to, if the terminal enters an overlapping area of first and second communication areas, extract an intensity of a beacon signal transmitted by a second base station managing the second communication area from the link layer state information database; and a handover unit to, if the intensity is greater than a critical value, add an IP address received from the second base station to the SCTP session, and to, if the intensity is greater than a second critical value, requests the second terminal to communicate with the terminal using the received IP address.
