Abstract: A heating appliance control system provides flame and heat control based on a flame signal indicative of a selected flame characteristic. The flame characteristic may correspond to the frequency and amplitude of the flame, or may relate to a mean flame temperature over time, flame color, size, movement patter, or other physical or aesthetic characteristic of the flame. The heating appliance may also include a scent delivery system and a sound system that function independently or in synchronization with the flame characteristics.

Abstract: A surround entertainment system configured for use with a heating appliance such as a fireplace includes a decorative surround, a display monitor coupled to the surround, a sound system positioned at least partially within the surround, and a signal module positioned at least partially within the surround and configured to provide a video signal to the display monitor and an audio signal to the sound system. The surround may include several recessed portions sized to receive the display monitor, sound system, and signal module.

Abstract: An electronic connection system suited for use with a fireproofed electronic device. The system includes a heat conductive wire having a connection point that includes a heat sensitive connecting material, and a biasing member configured to apply a tension force to the heat conductive wire point. The heat sensitive material is modified when heat is applied to the heat conductive wire such that the tension force from the biasing member thermally separates the heat conductive wire.

Abstract: A hydronic heating system that includes a liquid-filled conduit and a combustion chamber enclosure having a plurality of panels that define a combustion chamber for the combustion of fuel to generate heat. At least one of the panels and a portion of the liquid-filled conduits are integrally formed together. The at least one panel absorbs heat generated in the combustion chamber and transfers the absorbed heat to the liquid in the conduit. The heated liquid may be transferred to a remote location where the heat is removed from the liquid using a heat exchanger. The at least one panel and the portion of the liquid-filled conduit may be integrally formed using a moldable material such as a ceramic fiber and a binder, and molded using such processes as compression molding or vacuum molding. The use of moldable may reduce condensation in or around the combustion chamber enclosure.

Abstract: An apparatus for generating a combustible gas flame above a surface of a liquid. The apparatus may include a manifold including a manifold space that is completely or partially positioned within the liquid and a combustible gas source. Combustible gas from the gas source may be delivered to the manifold space and delivered into the liquid or a space above the liquid. The combustible gas may then be ignited to create a combustible gas flame. The combustible gas may also be mixed with air or liquid prior to delivery to the manifold space. In addition, a pump may be included to pump a supply of liquid out a liquid outlet to create a desired effect. Alternatively, the apparatus may be disposed on a float on the surface of the liquid.

Abstract: A body tissue graft for use in a patient includes a frame structure made of a first elastic material, a covering of a second elastic material on the frame structure, the covering substantially filling openings in the frame structure, and a connector connected to the frame structure. Projections are secured to the connector structure. The projections facilitate attachment of the tubular graft in a patient by securing the graft to the body tissue with which the graft is employed. The connector selectively circumferentially expands and the projections selectively circumferentially expand. This may be done using an inflatable balloon to circumferentially expand the projections. A restraining member may be provided to restrain the projections in a cone shape so that an end of the graft may be used to open an aperture through a side wall of existing body organ tubing and a portion of the projections may enter the aperture.

Abstract: The present invention relates to heating systems for umbrella-shaped structures. The heating system may include a shroud or umbrella-shaped structure defining an inner volume, and a plurality of electrical infrared heating elements positioned generally downward facing in the inner volume of the shroud. The shroud may include radially extending support structures to which the heating elements are mounted.

Abstract: The present invention generally relates to a use of a thermoelectric module in conjunction with a fireplace or stove to generate electricity to run certain features or peripheral devices related to the stove or fireplace. The thermoelectrical module may be positioned between interior and exterior walls of the stove or fireplace outside and protected from the fire generated in the combustion chamber of the stove or fireplace. Power generated by the thermoelectric module may be used for various purposes such as powering a blower, a control unit such as a microprocessor, lights, back-up systems, ignition systems, and flame control devices. Furthermore, the power generated by the thermoelectric module may be saved in a power storage device such as a rechargeable battery or capacitor for a later use by various devices associated with fireplace or stove.

Abstract: An air filtration and sterilization system for removing airborne contaminants from air circulated through an air plenum system of a fireplace. Air filtration systems may include particulate, chemical, and ion filtration systems to filter the air. Air sterilization may include ultraviolet, ozone, germicidal coating, and channeled system of ducts systems to sterilize the air. Systems may be used individually or in combination. In addition, optional components, including a warning sensor for indicating when to replace a filter, an automatic initiation sensor for activating and stopping filtration and sterilization, and an air enhancement system for introducing desirable materials into the air, may be provided.
