Abstract: Provided are a method, system, and article of manufacture in which a server computational device establishes communications over a network with a dental imaging system. An order is received to fabricate a dental device based on dental imagery acquired via the dental imaging system. A discount based on a cost of fabrication of the dental device is computed and communicated. Provided also is an intra-oral imaging system, where the intra-oral imaging system comprises an intra-oral imaging sensor, a display, and a processor coupled to the intra-oral imaging sensor and the display. The intra-oral imaging device acquires dental imagery, and establishes communications over a network with a server computational system. The intra-oral imaging device sends, an order to fabricate a dental device based on the acquired dental imagery, and receives communications of a discount based on a cost of fabrication of the dental device.

Abstract: A gas barbecue that has a housing having a generally rectangular shape with opposing side and end walls, an open interior, an open top, gas control means, a cooking grill, a primary burner assembly located below the cooking grill, and an upper radiant burner. The upper radiant burner is positioned above the cooking grill and includes a tube burner and a radiating means. The radiating means has a perforated mesh with the tube burner positioned beneath the perforated mesh such that heat generated by the tube burner passes through holes in the perforated mesh thereby heating the perforated mesh and causing the mesh to generate and direct infrared radiant heat into the open interior of the barbecue. The holes in the perforated mesh help to enhance the heating of the radiating means and assist in the radiation of infrared heat into the open interior of the barbecue.

Abstract: A gas barbecue having a rectangular body, gas control means, a cooking grill, and a burner assembly. The burner assembly includes an elongate tube burner and a generally L-shaped tube burner having a primary tube member and a secondary tube member intersecting the primary tube member thereby forming the general L shape. The free end of the secondary tube member is positioned in close proximity to the elongate tube burner such that the ignition of the elongate tube burner causes cross-ignition of the L-shaped tube burner when gas is supplied thereto.
