Abstract: Devices and methods that allow for rapid and efficient changing of duvet covers, comprising an upper section and a lower section of washable material that are sized to be significantly larger than a duvet that will be covered and isolated. The upper and lower sections are secured together along a single edge only, and that edge is positioned at the head of the bed. The duvet is placed between the upper and lower sections, isolating and enclosing the duvet, thereby preventing the duvet from becoming exposed while the bed is in use, and simultaneously allowing for easy and rapid changing of the duvet cover after use.

Abstract: A data processing system provides a method and apparatus for managing a shared resource between multiple processors. The data processing system includes a first processor for producing, or supplying, available sections of the shared resource, and a second processor for consuming, or allocating, the available sections within the system. The first and second processor share a memory containing a circular queue, a resource queue, for referencing available shared resource sections. The resource queue is initialized by storing a pointer to an available shared resource section in each entry of the resource queue. The second processor consumes an available section of shared resource by removing a resource pointer from a resource queue entry and sending a message signal to a mailbox message subsystem of the first processor.

Abstract: A mailbox message system is coupled between a processor having a mailbox and one or more peripheral devices or circuits communicating information to the processor. The mailbox message system in the present invention reports events which occur in the peripheral devices or circuits to the mailbox within the processor to be serviced by the processor. The mailbox message system receives inputs from the processor indicating which events are allowed to be currently serviced by the processor and stores these inputs in a first memory. The mailbox message system further receives unique signals representing distinct events from the peripheral devices and stores these signals in a second memory. The generated events which are pending service in the second memory are then compared with the allowed events in the first memory. When a match exists, a message is encoded and transmitted to the mailbox of the processor indicating that the processor has an event to be serviced.
