Abstract: A slow-release irrigation device having a housing with an open and closed end, and a water reservoir located therein, a circumferential channel located proximal to the open end providing a watertight engagement with a neck opening of a beverage container, a water channel connected to the water reservoir and having a water receiving inlet and an outlet for directing water into the water reservoir while simultaneously operating as a water seal for the housing, a housing water outlet located between the ends of the housing and directly connecting the water reservoir with the external environment, an air channel located within the housing, an air tube connecting the water reservoir to an interior of the container; and a permeable membrane located within the air channel and controlling the passage of air through an air outlet of the air tube.

Abstract: The possible network ports of a computing device are determined, regardless of whether they are currently usable. A network address is assigned to each possible network port. The network ports can include physical network ports and virtual network ports. Physical network ports can include physical network ports that are physically present, currently activated, and currently usable within the computing device; physical network ports that are physically present, not currently activated, and not currently usable within the computing device; and physical network ports that are not physically present and not currently usable within the computing device. Virtual network ports can include virtual network ports that have been instantiated and that are currently usable; and virtual network ports that have not been instantiated and that are not currently usable.

Abstract: Apparatus for applying a fluctuating stress to, for example, a gable end of a house includes a pressure enclosure. An air compressor is connected to the pressure enclosure via a series of gauged valves whose positions are continuously variable between limiting positions where the air compressor supplies all its output to, or takes all its output from the pressure enclosure. The effects of gusty winds can thus be simulated.
