Abstract: A foldable barbecue grill is provided herein. The barbecue grill mainly contains a bottom shelf with wheels, a pair of side racks, diagonal brackets, and a barbecue stove. The legs of the side racks are hinged to the four corners of the bottom shelf. Foldable diagonal brackets are configured between the bottom shelf and the legs of the side racks. A number of locking members are configured between the barbecue stove and the side racks to join them together. By releasing the locking members, the barbecue stove could be separated from the side racks. Then, the diagonal brackets are disengaged so that the side racks are retracted and rest on the bottom shelf Then, the separated barbecue stove could be placed on top of the folded side racks so that the entire barbecue grill, with its significantly reduced height, could be easily stored for later use.

Abstract: A tube burner flame hole construction with both sides of the tube provided with a row of multiple flame hole walls; each wall being compressed in a shape of a lip with both sides slightly protruding outwardly from the tube; a hole being provided in the center of the recessed lip to facilitate the punching process and improve structural strength of the of the entire tube burner, flame hole being more sturdy and thicker for consistent burning effects and longer service life of the tube burner.

Abstract: A barbecuing push cart employing LPG and charcoal for barbecuing is disclosed. The barbecuing push cart comprises a hand-pushing cart and a barbecuing oven mounted on the push cart. The opening of the oven has an inner edge wall on which a barbecuing net can be mounted. The internal bottom section of the oven housing is provided with an LPG oven plate. An elevating device having a charcoal plate is provided between the oven opening and the LPG oven plate. One side end of the elevating device is horizontally projected out with a rocking shaft which is projected through the oven and extended toward the user. A downward lifting door is formed at the elevating device and the elevating region of the charcoal plate. An ignition element linked to the LPG stove plate is protruded out from the oven and an ignition button is formed. The frame wall of the oven housing, corresponding to the rocking shaft, is a multi-stage engaging slots. Thus, the barbecuing oven can be operated using both charcoal and LPG.

Abstract: An improved structure of a working platform having a rectangular base plate, four rollers, a pair of inverted U-shaped frame supports, at least a pair of lateral support rod, a plurality of screws and at least a lateral flat plate, characterized in that the four corners of one face of the base plate are mounted with the rollers and the other face of the base plate is disposed with connection blocks, and the frame supports comprises a horizontal beam having two ends bent to form an erect tubes and the horizontal beam is protruded with a plurality of horizontal holding blocks along the direction of the lateral flat plate so that a lateral shielding plate is formed between the two erect tubes, and the erect tubes connect other tube opening of the horizontal beam is inserted correspondingly to the connection blocks. The other end of the erect tube is provided with a fastening slit, and one rod end of the lateral support rod bends out to form a top fastening plate and a bottom fastening plate.

Abstract: A smokeless grilling oven is disclosed. The oven comprises a grate, a frame body, a plurality of infra-red heaters which equals the number of sides of the frame body, and a slanting securing rack for mounting the heaters, wherein the grate is placed onto the frame body and the bottom edge of the frame body suspends the slanting securing rack and the infra-red heaters are mounted onto the slanting securing rack so that the emitting end of the heater is slopingly facing the bottom of the grate.

Abstract: Systems and methods are disclosed for protecting a computer program from unauthorized analysis and modification. Obfuscation transformations can be applied to the computer program's local structure, control graph, and/or data structure to render the program more difficult to understand and/or modify. Tamper-resistance mechanisms can be incorporated into the computer program to detect attempts to tamper with the program's operation. Once an attempt to tamper with the computer program is detected, the computer program reports it to an external agent, ceases normal operation, and/or reverses any modifications made by the attempted tampering. The computer program can also be watermarked to facilitate identification of its owner. The obfuscation, tamper-resistance, and watermarking transformations can be applied to the computer program's source code, object code, or executable image.
