An out-the-front automatic knife incorporates dual locking and release mechanisms that define a three-point blade-handle interconnection between the blade and the handle when the blade is locked in the open position. Methods and machine-readable medium implementing the method steps are also disclosed. The handle body has a grip portion that is gripped by a user in use. The handover management element may be further configured to receive a request for a connection from the mobile terminal subsequent to a radio link failure and prior to handover completion. The utilization area can include a larger emission region than that of the conventional linear light source so that a higher-intensity light beam with a narrower half-beam width can be obtained at the converging point. As a result of the determination, when there is the same type of message, a content of the handoff request message waiting for the retransmission or the transmission is updated to a content of the new generated handoff request message.
