Abstract: A method and system for monitoring using a sub-slab sensor assembly for a building having a slab includes a housing, a first air quality sensor coupled to the housing and generating a first air quality signal for air above the slab, a second air quality sensor coupled to the housing and generating a second air quality signal for air below the slab and a pressure sensor coupled to the housing. The pressure sensor generates a pressure signal corresponding to the pressure below the slab. A position sensor generates a position signal corresponding to a location of the sensor. A network interface communicates the first air quality signal, the second air quality signal or the pressure signal, or warning signals corresponding thereto and the position signal to a network.

Abstract: A camera crane mobile base for carrying a camera crane includes a first powered remotely controllable steering system having first and second axle assemblies at a first end of a chassis. A second steering system including third and fourth axle assemblies is provided at a second end of the chassis. A first electrically powered remotely controllable propulsion system includes an electric propulsion motor connected to first and second axles in the first and second axle assemblies. A telescoping center post is pivotally attached to the chassis. An on-board hydraulic system may power the first steering system and the telescoping center post.

Abstract: A remotely controlled camera head has a pan frame including a first rectangular section. An upper end of a second rectangular section is joined to the left side of the first rectangular section. A pan motor in the first rectangular section of the pan frame rotates the pan frame about a pan axis co-axial with a hub when the pan motor is on. A tilt frame is rotatably attached to the lower end of the second rectangular section and movable about a tilt axis. In a two axis mode, a camera platform is attached to the tilt frame. A slide out may be used to change the length of the tilt frame. A tilt motor within the second rectangular section is connected to the tilt frame for rotating the tilt frame about a tilt axis when the tilt motor is on.
