Abstract: Disclosed is a keylock device for a circuit breaker. The keylock device for a circuit breaker comprises a closing lever configured to generate a closing operation of a mechanism, a trip lever configured to generate a trip operation of the mechanism, and a locking unit configured to allow a locked state of the locking unit to be maintained when the mechanism is in an ‘ON’ state, but to allow the locked state of the locking unit to be converted into a released state when the mechanism is in an ‘OFF’ state. Under these configurations, it is impossible to convert the current state of the keylock device into a locked state unless the mechanism of the circuit breaker is converted into an ‘OFF’ state. This may prevent the occurrence of an accidence due to the operator's unintentional ‘OFF’ state of the mechanism.

Abstract: Provided is an apparatus and method for controlling multi-channel access in USN-based MAC. The multi-channel access control apparatus includes a channel scanner, a control channel preoccupier, and an available channel exchanger. The channel scanner scans at least one or more available channels among the N data channels in a Tx sensor node. The control channel preoccupier preoccupies, in the Tx sensor node, the control channel through control channel sensing and back-off and broadcasts a preamble on the control channel periodically. The available channel exchanger detects, in an Rx sensor node, the available channels available to the Tx sensor node on the basis of the received preamble, selects a channel available to the Rx sensor node among the detected available channels, and transmits information about the selected channel to the Tx sensor node.
