Abstract: A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.

Abstract: A system for emitting light (such as a luminaire) includes a first light emitting diode (LED) string and a first LED driver that is electrically connected in parallel to the first LED string. The system also may include a second (or more) LED string(s), each associated with an additional LED driver. One-way conductors and normally-open switches are used so that if one LED driver fails, the remaining LED driver(s) will deliver power to the failed driver's LED string so that the light remains operational, but with a reduced brightness.

Abstract: A method and system for an enhanced weighted fair queuing technique for a resource are provided. A plurality of request streams is received at a requestor, each request stream including request messages from a process executing on the requestor. The request messages of each request stream are apportioned to an input queue associated with the request stream; each input queue has a weight. A virtual finish time is determined for each request message based, at least in part, on the weights of the input queues. A sequence of request messages is determined based, at least in part, on the virtual finish times of the request messages. The sequence of request messages is enqueued into an output queue. The sequence of request messages is sent to a resource, over a connection, which provides a service for each process.
