a pivot shaft provided on the first lateral side portion of said hand insertion door board, wherein said hand insertion door is supported so as to be pivotal about a vertical axis of said pivot shaft;
a bracket attached and fixed on a holding portion of said hand insertion door board; said latch mechanism comprising a latch lever configured to pivot between a hold position for the holding of said hand insertion door and a release position for releasing the holding of said hand insertion door on the side surface of the newborn infant container and a press lever configured to pivot about an axis identical or parallel to a pivot axis of said latch lever to make said latch lever pivot to the release position, wherein said press lever and said latch lever are separate units, wherein said latch lever is separate from and pivotable within said press lever, wherein said latch mechanism is provided on the second lateral side portion of said hand insertion door board, wherein said latch mechanism holds said hand insertion door at a closed position by pressing a tongue-like portion on a distal end side of said hand insertion door, wherein said latch lever is pivotally supported by a vertical support shaft supported by said bracket, wherein said latch lever is pivotally biased by a biasing spring to cause a distal end side projection to press the tongue-like portion on the distal end side of said hand insertion door so as to hold said hand insertion door at the closed position;
said press lever is pivotally supported by said support shaft on said bracket; and
when said press lever is pressed, said press lever presses a projecting piece of said latch lever to make said latch lever pivot to the release position.
2. An incubator according to claim 1, further comprising:
an opening mechanism configured to bias said hand insertion door in an opening direction by abutting against the hand insertion door during pivoting of said hand insertion door in a closing direction before completion of a closing operation.
3. An incubator according to claim 1, further comprising:
a braking mechanism configured to brake the pivoting of said hand insertion door for at least a portion of an opening operation during the pivoting of said hand insertion door in an opening direction.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A network comprising a plurality of nodes, the plurality of nodes comprising a first node and a second node. the first and second nodes being connected through the network of nodes via a first path and a second path, the first and second paths being different, in which the network has first and second modes of operation, a first mode in which traffic between the first and second nodes is transmitted over the first path and not the second path, and a second mode where the traffic is transmitted over the first and second paths, wherein the network comprises a mode selector arranged to select the mode of operation based upon a demanded level of traffic between the first and second nodes.
2. The network of claim 1, in which the second path comprises a protection path such that the network has a third mode of operation in which traffic between the first and second nodes is sent over only the second path, and in which the mode selector is arranged to select this mode should there be a fault on the first path.
3. The network of claim 1, in which the selection of the mode of operation dependent upon the demanded level of traffic depends upon the rate at which data to be transmitted across the link is received.
4. The network of claim 1, in which the network further comprises a priority assignor, which is operable to assign a priority to the assignment of data between the first and second paths.
5. A network node for use in sending data to a destination node in a network, the network node comprising a first network interface and a second network interface, in which the network node has first and second modes of operation, a first mode in which the network node transmits data for the destination using the first network interface and not the second network interface, and a second mode where the data for the destination node is transmitted over the first and second network interfaces, wherein the network node comprises a mode selector arranged to select the mode of operation based upon a demanded level of traffic for the destination node.
6. The network node of claim 5, in which the first network interface is connectable to a first path across the network to the destination node and the second network interface is connectable to a second path across the network to the destination node.
7. The network node of claim 5, in which the network node comprises a protection switch, whereby in case of a fault traffic for the destination node is sent via the second network interface should there be a fault on a link from the first interface to the destination node.
8. The network node of claim 5, in which the selection of the mode of operation dependent upon the demanded level of traffic depends upon the rate at which data to be transmitted across the link is received.
9. The network node of claim 5, in which the network node further comprises a priority assignor, which is operable to assign a priority to the assignment of data between the first and second paths.
10. A method of operating a network, the network comprising a plurality of nodes, the plurality of nodes comprising a first node and a second node, the first and second nodes being connected through the network of nodes via a first path and a second path, the first and second paths being different,
the method comprising the operation of the network in first and second modes of operation, a first mode in which traffic between the first and second nodes is transmitted over the first path and not the second path, and a second mode where the traffic is transmitted over the first and second paths, and wherein the mode of operation is selected based upon a level of traffic between the first and second nodes.
11. The method of claim 10, in which the second path comprises a protection path such that the network is operated in a third mode of operation in which traffic between the first and second nodes is sent over only the second path, and in which the third mode is selected should there be a fault on the first path.
12. The method of claim 10, in which the selection of the mode of operation dependent upon the demanded level of traffic depends upon the rate at which data to be transmitted across the link is received.
13. The method of claim 12 in which the selection is made dependent upon whether the rate exceeds a threshold.
14. The method of claim 13, in which the threshold is a fraction of an available bandwidth of the first path.
15. The method of claim 10, in which the method comprises the step of assigning a priority to the assignment of data between the first and second paths.
16. The method of claim 15, in which data that is potentially to be routed onto the second path because of a failure in the network is assigned a higher priority than that assigned to data potentially to be assigned to the second path because of traffic levels.
17. A method of operating a network node so as to send data to a destination node in a network, the network node comprising a first network interface and a second network interface, in which the method comprises operating the network node in first and second modes of operation; a first mode in which the network node transmits data For the destination using the first network interface and not the second network interface, and a second mode where the data for the destination node is transmitted over the first and second network interfaces, and wherein the mode is selected based upon a level of traffic for the destination node.
