Abstract: A method of defrosting an energy recovery ventilator unit. The method comprises activating a defrost process of an enthalpy-exchange zone of the energy recovery ventilator unit when an air-flow blockage in the enthalpy-exchange zone coincides with a frost threshold in the ambient environment surrounding the energy recovery ventilator unit. The method also comprises terminating the defrost process, including terminating the defrost process when an operating condition in the vicinity of the enthalpy-exchange zone substantially returns to a pre-frosting operating condition.

Abstract: An energy recovery ventilator unit. The unit comprises a cabinet housing a primary intake zone, a supply zone, a return zone, an exhaust zone and an enthalpy-exchange zone. The primary intake zone and the exhaust zone are both on one side of the enthalpy exchange zone. The supply zone and the return zone are both on an opposite side of the enthalpy exchange zone. The unit also comprises first and second blowers. The first blower is located in the primary intake zone and configured to push outside air into the primary intake zone and straight through the enthalpy exchange zone into the supply zone. The second blower is located in the return zone and configured to push return air into the return zone and straight through the enthalpy exchange zone into the exhaust zone.

Abstract: An energy recovery ventilator unit comprising a cabinet and a plurality of enthalpy wheels mounted in the cabinet. Major surfaces of each of the enthalpy wheels are substantially separated from each other and substantially perpendicular to a direction of primary forced-air intake into the cabinet. The major surface of one of the enthalpy wheels substantially overlaps, in the direction of primary forced-air intake, with the major surface of at least one of the other enthalpy wheels.

Abstract: A heating ventilation and cooling system includes an energy recovery ventilator (ERV). The ERV is configured to produce an inlet airstream and an exhaust airstream. An enthalpy wheel within the energy recovery ventilator is operable to transport heat between the inlet and exhaust airstreams. A pressure transducer is configured to determine a backpressure across the enthalpy wheel. A controller is configured to determine, in response to the backpressure, an operational characteristic of the enthalpy wheel.

Abstract: An energy recovery ventilator includes first and second blowers, a pressure transducer and a controller. The first blower is configured to direct a first air stream into a first zone of an enclosure. A second blower configured to direct a second air stream into a second zone of the enclosure. A pressure transducer is configured to determine internal air pressure within the enclosure. A controller is configured to control the first blower and/or the second blower in response to the internal air pressure.

Abstract: One aspect, as provided herein, is directed to a multi-stage fluid control system for a fluid source heat pump system. This embodiment comprises compressors configured to operate as separate, heat exchange stages, condensers each being fluidly coupled to at least one of the compressors by refrigerant tubing and having intake ends coupled together by a fluid intake manifold. This embodiment further includes output conduits coupled to each of the condensers and that are couplable to a distal location. Further included is a modulating valve control system interposed the output conduits. The modulating valve control system is configured to stage a flow of fluid through the condensers based on a number of operating compressors.

Abstract: Managing playlists, comprising: displaying a current playlist and one or more playlists that intersect the current playlist at a current media item; selecting one of the following: (1) when a pivot command to pivot from the current playlist to a pivoted playlist is received, first moving to a next media item of the pivoted playlist, and displaying the pivoted playlist and one or more playlists that intersect the pivoted playlist at the next media item of the pivoted playlist; (2) otherwise when no pivot command is received, second moving to a next media item of the current playlist, and displaying the current playlist and one or more playlists that intersect the current playlist at the next media item of the current playlist.

Abstract: Containers provide for portability and ease of handling by being constructed of pliable materials such as various polymers and having additional features. The containers may have biasing members such as tension poles to hold the containers in an upright and open top position and/or may have sleeves that can be engaged by a forklift for dumping of the container by a conventional forklift equipped garbage truck. The containers may include additional features such as loops along a top edge to allow grasping of the loops by a lift and loops along a bottom edge to allow dragging of the container such as onto a flatbed hauler. Additional features may include a top cover that can be pulled over the open top and secured such as by a fastener.

Abstract: The present invention relates generally to the destruction of chemical weapons. In particular, the present invention relates to methods for treating hydrolysates of chemical agents. In one embodiment, the present invention provides a method comprising oxidizing a hydrolysate of a chemical agent to produce an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and separating the organic layer from the aqueous layer.

Abstract: Fixture guard panels and systems provide protection for fixtures such as tubs and showers. The fixture guard panels may have a variety of configurations such as including an enclosure formed of a flexible material that contains a padding layer. The panel may be placed adjacent the fixture such that the panel protects the fixture from impacts and abrasions. The panel may include individual sheets of material to enclose padding, may include padding without an enclosure, or may include an individual sheet without padding. The individual sheets may be materials such as polyethylene and/or non-skid rubber. For panels with non-skid rubber, the panel may be positioned so that the non-skid rubber portion contacts the fixture and will not skid. Panels may include flexible sheets with adhesive that adheres to the fixture, such as upon vertical fixture surfaces. Additionally, multiple panels may be included as a system.

Abstract: Maintenance of community integrity in a gaming network is disclosed. One or more devices interacting with a particular game in the gaming network may be monitored. During the course of monitoring these devices, indicia of the violation of certain rules that define fair game play may be identified. A user and/or device engaged in certain illicit game play activity that resulted in the violation of the rules that define fair game play may subsequently be identified. The identified user and/or device may then be penalized as to maintain the integrity of the gaming community. Various penalties may be implemented, including ejection from the gaming network or prohibitions with regard to future access to the gaming network. Various retributive actions may also be taken against a particular user who has engaged in illicit game play activity with respect to future game session activity.

Abstract: A system and method for passively validating network game users is provided. Data indicative of game behavior and actions at one or more nodes interacting with a network game in a network game community are monitored. The data is evaluated to determine whether the one or more nodes are adhering to one or more rules associated with the network game. Data indicative of illicit game behavior may trigger various responses including invalidation of the node engaged in the illicit behavior. Alternatively, a query may be generated to further identify the nature and/or actual existence of illicit behavior at the node. Monitoring of game data may occur at a server, a peer, as part of a peer group or combinations thereof, which may be based on routine schedule or part of constant game behavior monitoring.
