Oxygen is removed or maintained in a sealed container by electrochemically reducing the oxygen to water using an enzymatic O2 scavenging system based on a laccase enzyme. Activation of the O2 scavenging system typically occurs by water (liquid or vapor) adsorption; in preferred embodiments, ascorbate and isoascorbate (and their corresponding acids) are especially advantageous for their dual role as reductant and hygroscopic agent. The capacity of the O2 scavenging system can be manipulated by altering the concentration of reductant that is included in the O2 scavenging composition. The O2 scavenging system can be prepared in a variety of formats (e.g., inks, labels, packets, liners, patches, caps, within the packaging material itself) and is readily produced by apparatuses conventionally used in the industry on a high speed continuous basis.

A communication apparatus includes a transmitter for transmitting wireless signals, and a receiver for receiving wireless signals. A first communication functional unit uses the transmitter and the receiver to operate as a station in a first network operating on a first communication channel, while a second communication functional unit uses the transmitter and the receiver to operate as a station in a second network operating on a second communication channel different from that of the first network. A controller conducts time division data transfer by utilizing the respective time periods of receiver inactivity on the first and second channels in order to switch operation to the other channel and attempt to receive a signal on the corresponding other network. In so doing, the communication apparatus is able to fulfill dual roles on the networks operating on different channels with the use of a single modem.

A shelter system is disclosed which comprises three central elements. A rotatable barrier element provides protection from incoming ballistic threats. The barrier functions on the principle of detonating, absorbing, and deflecting incoming threats away from a designated area of the shelter. A protective envelope element utilizes a compartmentalized vessel, two containment components, and a strata of alternating compacted fill and interstitial plate layers; the strata is enclosed within the vessel and two containment components. The interstitial plates serve a dual role in providing a compaction surface in the fill method and layering for the mitigation of ballistic threats.

A method for switching a dual role device (DRD) between the roles of a host and a device is provided. In the role switching method, when there is a request from a DRD desiring a role switch, a partner DRD may switch its own role. The role may be switched based on a plurality of consecutive micro-scheduled management commands (MMCs) or based on specific bit values included in a wireless universal serial bus (W-USB) application specific information element (ASIE) of a beacon slot. Therefore, the role switching method may reduce overhead by not having to simultaneously and continuously maintain a default link and a reverse link. The DRD may perform the role switching method.
