Abstract: An apparatus includes a hub and multiple thin, flat, deformable panels. Each panel is a trapezoid with parallel base and top. The panels are foldably connected together base-to-top to form a closed ring. A proximal end portion side of each panel is attached the hub. A proximal portion of each panel is wound around the hub; a distal portion of each panel extends tangentially away from the hub. Proximal portions of each panel winding around the hub decreases an apparatus outer diameter; proximal portions of each panel unwinding from around the hub increases the apparatus outer diameter.

Abstract: According to examples, a system for generating and providing organization-bounded spaces for a virtual community of users may include a processor and a memory storing instructions. The processor, when executing the instructions, may cause the system to generate an organization-bounded space; analyze user information to associate a user with the organization-bounded space; enable the user to receive and publish a content item; and implement a security feature for communications associated with an organization-bounded space and/or its associated users. The processor may further determine recommend a group to the user and identify a user representative for the organization-bounded space.

Abstract: Described herein includes a puncture mechanism for a beverage appliance or machine that can be configured to puncture a pod containing a beverage medium (e.g., a flavoring agent). The puncture mechanism can be configured to induce lateral movement of one or more engagement members to securely hold a beverage pod. The puncture mechanism can be configured to induce relative axial movement between an anvil and the secured beverage pod to puncture a seal of the beverage pod.

Abstract: The invention provides methods for the measurement of carbon dioxide leakage from sequestration reservoirs. Tracer moieties are injected along with carbon dioxide into geological formations. Leakage is monitored by gas chromatographic analyses of absorbents. The invention also provides a process for the early leak detection of possible carbon dioxide leakage from sequestration reservoirs by measuring methane (CH4), ethane (C2H6), propane (C3H8), and/or radon (Rn) leakage rates from the reservoirs. The invention further provides a method for branding sequestered carbon dioxide using perfluorcarbon tracers (PFTs) to show ownership.

Abstract: A wave collector structure (51) for electrical power generation powered by wave energy comprises an outwardly extending and downwardly depending lip (105, 107) below which is situated a mouth (61, 67) of the collector. The collector further comprises side walls (75, 79) for channelling waves into the collector mouth. These side walls (75, 79) extend horizontally substantially up to or beyond the lip, partially enclosing a volume of water between the lip and side walls. The collector is placed in its desired location by sealing the mouth (61, 67) with gates (not shown) and floating the structure to its desired location. Control valves are opened to allow water into the collector to sink the structure to the sea bed (63) whereupon the gates are removed.
