Abstract: A barbeque cooker in which the food stays at a predetermined level and a fire tray assembly can be adjusted as to vertical position relative to the food. The fire tray assembly includes two spaced apart parallel fire trays (for holding burning fuel) that are independently adjustable as to horizontal position. Vertical and horizontal adjustments are accomplished with hand cranks making for precise adjustments. The vertical adjustment hand crank operates a scissor jack assembly. A drip tray is attached to the top of the scissor jack assembly. The fire tray assembly is attached to and vertically spaced apart from the drip tray, allowing space for the horizontal adjustment screws. The scissor jack assembly is attached to front and rear end frames, each having a top portion configured to support a rotisserie and to support a grill. Two embodiments are presented, having different configurations of the horizontal adjustment screw assemblies.

Abstract: A network accessing method includes selecting a group representative dynamically from each machine to machine (M2M) terminal group, wherein terminals in the M2M terminal group not selected as the group representative serve as group members. The method also includes requesting, by the group representative, network access from a base station, and serving, as a group member automatically after entering an idle state or entering another cell. This enables multiple M2M terminals to access a network at the same time while avoiding network access congestion.

Abstract: A method for random access of Machine to Machine (M2M) terminals is applied to a plurality of M2M terminals. The method includes dividing the plurality of M2M terminals into at least one terminal group, and allocating an identifier for each terminal group. After receiving the paging broadcast signaling transmitted by the base station, an M2M terminal in a terminal group determines whether the terminal group identifier carried in the paging broadcast signaling is the identifier of the terminal group that includes the M2M terminal. If true, the M2M terminal starts a random access process. A base station transmits a paging broadcast signaling on the basis of a terminal group rather than issuing a paging broadcast signaling only to individual M2M terminals so that a plurality of M2M terminals can be randomly accessed smoothly and efficiently without causing network access congestion nor affecting the use of public network users.
