Abstract: A vehicular trunk-through openable and closable device (5) whose unlocked condition can be more easily checked than has conventionally been done. When releasing a locked condition of an opening and closing unit (11) using an unlocking unit (12), the unit (11) is rotated in a forward-folding direction by an elastic force caused by an elastic member (30). A gap is formed between the unit (11) and a trunk-through section (3) without bringing the unit (11) into a fully open condition. Hence, it can be visually checked whether the gap has been formed between the unit (11) and the trunk-through section (3) or not, thus enabling a user to instantly determine whether the locked condition has been released by the unlocking unit (12). Thus, an unlocked condition of the vehicular trunk-through openable and closable device (5) can be much more easily checked than has been conventionally done.

Abstract: A mechanism for identifying link failures in a network is disclosed. To identifying link failures, a failed-link discovery mechanism receives information that represents a physical topology of the network. A management station that is associated with the network is identified and a path between one or more devices of the network and the management station is determined. For each link, a set of beyond link devices, that identifies only those devices that are beyond a particular link relative to the management station, is identified. Thereafter, a first message is sent to each active device within the network. Based on the responses that are returned in response to the first messages, a set of non-responding devices within the network is determined. The set of non-responding devices is then compared to each set of beyond link devices to identify link failures within the network.
