Abstract: A burner for use in a hydrogen burning appliance that includes a gas enclosure defining a gas distribution chamber and a gas aperture, a burner having a combustion surface, a hydrogen gas source coupled to the gas enclosure, and a flame enhancement member positioned in a path of the combusting hydrogen. The hydrogen gas source supplies hydrogen gas to the gas chamber for distribution to the gas aperture for combustion of the hydrogen gas at the combustion surface. The flame enhancement member may alter properties of the flame such as the flame color.

Abstract: A secured file cabinet having a mechanical locking mechanism movable between locked and unlocked positions and a biometric data scanner for activating the locking mechanism. The biometric data scanner is based on fingerprints, iris recognition, retina recognition, voice recognition or any other biometric data. The scanner initiates a signal, if a match is found with stored data, to a solenoid in one embodiment, or a motor in another embodiment, to move a tab or a bar from a locking position relative to a file cabinet drawer. A light system may be used to indicate whether the cabinet is locked or unlocked.

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: 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: 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.
