A reconfigurable holographic antenna includes a metamaterial layer and a waveguide with at least one ridge. The metamaterial layer includes an array of tunable slots configurable to form holographic diffraction patterns. A reactance of each tunable slot in the array of tunable slots is individually tunable. The at least one ridge influences coupling between tunable slots in the array of tunable slots. The holographic diffraction patterns formed by the array of tunable slots generate a desired antenna wave in response to a received feed wave.

A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has a rounded shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the rounded shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

An aeration assembly for aerating liquids including wine and other alcoholic beverages includes an expansion chamber and an aerating device. The expansion chamber is configured to be in fluid communication with an inside of the uncorked and/or opened bottle when engaged by a bottom portion of the expansion chamber. The aerating device comprises a gas conduit having a proximal end in fluid communication with a distal end. The distal end is disposable below the bottom portion of the expansion chamber. A gas source is in fluid communication with the proximal end of the gas conduit. The expansion chamber is configured to temporarily contain an expansion of bubbles during an aeration process. The expansion chamber and aerating device are not permanently connected, wherein the aerating device can be fully removed from the expansion chamber before, during or after the aeration process.

A wine aerator includes a gas conduit having a proximal end in fluid communication with a distal end, wherein the gas conduit passes through a seal and wherein the distal end is configured to be insertable into an inside of an uncorked wine bottle. A gas source is connectable to the proximal end of the gas conduit and is in fluidic communication with the gas conduit, wherein the gas source comprises an air pump having an adjustable flow rate of at least 0.1 liters per minute up to a maximum of 20 liters per minute. A bubble-generating aeration element is disposed at the distal end of the gas conduit and in fluidic communication with the gas conduit. The bubble-generating aeration element comprises a porous material having an average pore size of at least 1 micron up to a maximum of 500 microns.

An electronically-operated gun safe or other lockable container is communicatively connected to an alarm system or one or more alarm system elements. When the alarm or the alarm system elements is/are triggered, a signal is received by the gun safe, which then unlocks the door to the gun safe to allow access to the contents of the gun safe, or takes other action to facilitate easier access to the contents of the gun safe.
