A combination firepit and water fountain having a fountain base with an opening in a top surface of the base. A circumferential ignition coil is located within the opening and is connected by a fuel supply line to a source of gaseous fuel for providing a fire. A circumferential flameproof enclosure surrounds the ignition coil in the top opening of the base. A fountain top is also located centrally within the top opening so that the flameproof enclosure surrounds and circumscribes the fountain top. A water pump located in the base supplies a water flow out the fountain top and down the sides thereof into the interior of the fountain base, where it is recirculated.

Hood assemblies for use in flaming crops having effective top, right and left lateral sides, on at least one of said effective top and/or lateral sides there being a double plate arrangement such that insulating air, which is free to flow, is present between said double plates. Distinguishing factors can include, at a longitudinally rearward end thereof, the presence of an upwardly opening chimney structure.

A torch comprising a functional combination of: 1) an ignition system having an internal bluff body wall, said ignition system having an open end and an end in which is present a spark plug; and 2) an elongated fuel line that is secured to said torch so that heat easily passes from hot gas and flame inside said torch thereinto during use, wherein the fuel line has a fuel flow swirl producing element therewithin; and 3) a thermocouple secured in place inside the torch to monitor temperature at a relatively high temperature location therein, such that if the temperature decreases while fuel is still flowing a signal is generated to provide a spark to the spark plug.

A smart electronic system is disclosed. The system can analyze any input voltage to determine whether the input voltage is sufficient to charge the battery of an electronic device and/or to operate the electronic device. If not, the cable is capable of transforming the input voltage to a voltage sufficient to charge and/or operate. The electronic device may be incorporated into the housing of the smart electronic system, and can be any known mobile devices.

An charge element disposed proximate to a combustion reaction is caused to carry a voltage while also being prevented from arc-discharging or arc-charging to or from the combustion reaction, by a current limiting element in electrical continuity with the charge element.

A spark detector indicates the presence of a spark by analyzing sound waves generated when an electrical spark is produced from an electrical spark generator located on an igniter rod. The spark detector includes an acoustic sensor that is in communication with the igniter rod to determine the time for the spark sound wave to travel through the igniter rod to the acoustic sensor. If a spark is not detected, the spark detector may output a signal indicating at least one of (i) the spark was not detected, (ii) to replace the electrical spark generator immediately, or (iii) replace the electrical spark generator soon such as at the next scheduled maintenance. Furthermore, the spark detector may be calibrated based on current temperature of the igniter rod based upon time of propagation of a pulse sound wave, generated by a pulse-echo generator, to reflect off an end of the igniter rod.

An igniter for a burner in a cooking system. The igniter comprises a spark unit including two electrodes that define a spark gap, a spark module electrically connected to the electrodes to apply a high-voltage pulse across the electrodes to generate a spark in the spark gap, and a remote sending unit that sends an ignite signal to the spark module to generate a spark in the spark gap to light the burner. A local ignite signal can be initiated from the spark module. The spark module and the remote sending unit can be clamped to a gas hose supplying gas to the burner. The spark unit can be attached to a variety of burners by attachments to position the spark gap in the burner's gas flow. A single-electrode igniter is also described.

An arc lighter fixing element includes a metal conduit and an arc lighter detachably installed to an end of the metal conduit. A plastic expansion member is latched into an end of the metal conduit. The arc lighter includes an arc generation head and a ceramic member installed on the top inner side of the arc generation head, and the bottom of the arc generation head is sheathed on the top of the metal conduit. A screw is passed through the center of the ceramic member and then secured with the plastic expansion member. The metal conduit may be bent conveniently to facilitate an ignition at different angles, and passed through an expansion structure to connect the arc lighter to the metal conduit, so as to facilitate the installation and disassembling.
