  • Patent number: 10912666
    Abstract: Disclosed herein is a leg exoskeleton configured to aid motion (e.g., walking) of a user in need thereof. In particular, the exoskeleton includes a belt configured to attach the exoskeleton to the waist of a user. The exoskeleton further includes a leg frame configured to attach to at least one leg of the user through a hip attachment mechanism on the belt. Finally, the exoskeleton includes an energy storage subsystem that is configured to store and release energy as the user walks, particularly aiding the user in the forward motion of the leg when walking. Methods of using the leg exoskeleton are also provided.

  • Patent number: 10015975
    Abstract: A smoker having an internal perforated smoke stack that is able to smoke food from both the inside and outside. Food is placed inside the smoker and positioned on the perforated smoke stack. The perforated smoke stack is directly connected to the charcoal pan such that smoke enters the perforated smoke stack and out the perforations, thereby providing heat and smoke to the inside of the food in addition to the heat and smoke permeating the smoker's body chamber outside the food.

  • Patent number: 9839323
    Abstract: A barbecue grill and components thereof that allow a user to obtain a controlled burst of high intensity heat for a limited period of time, comprising at least one quick sear burner, a quick sear valve assembly adapted for fluid communication with the quick sear burner, and a cooking surface adapted to be positioned above the quick sear burner in or on a firebox of a barbecue grill. The quick sear valve assembly, in turn, comprises a main valve for normal operation of the quick sear burner, and a bypass valve for high intensity heat output of limited duration. The quick sear valve assembly includes a mechanism that is configured to allow the user to selectively actuate the bypass valve.

  • Patent number: 8613276
    Abstract: A duel fuel gas control valve controls the supply of gas (e.g., natural gas or liquid propane gas) to a gas grill. The duel fuel gas control valve is structured to control either natural or LP gas flow at the desired operating characteristics based on conventional gas supply characteristics and gas grill requirements. A restrictor mechanism, when in first and second configurations, respectively, restricts movement of the valve core to a first predetermined range for a first mode of operation (first type of gas supply) and to a second predetermined range for a second mode of operation (second type of gas supply).
