Abstract: A drain plug for selectively draining a source of fluid is described, and which includes first, second and third portions which provide coaxially aligned fluid passageways which extend therethrough, and wherein the second portion is moveable relative to the first and third portions between a first position which substantially occludes, and prevents the passage of fluid through the coaxial aligned fluid passageways, and a second position where fluid is allowed to pass therethrough and may be collected for disposal as required.

Abstract: A processor having a dependency matrix comprises a first array comprising a plurality of first cells. A second array couples to the first array and comprises a plurality of second cells. A first write port couples to the first array and the second array and writes to the first array and the second array. A first read port couples to the first array and the second array and reads from the first array and the second array. A second read port couples to the first array and reads from the first array. A second write port couples to the second read port, reads from the second read port and writes to the second array.

Abstract: A method and system of controlling an audio switch at a receiving unit during handoff is disclosed herein. The method can include the step of—at a receiving unit with an audio call active on a first network supporting a first audio protocol—setting up a second audio call on a second network supporting a different audio protocol. The method can further include the steps of monitoring for one or more events, detecting one or more of the events, and in response to the detection of one or more of the events, switching an audio path of the receiving unit from the first network to the second network.
