Abstract: Systems and methods of the present disclosure include at least one building component detection sensor device configured to be deployed within (or proximate to) a building comprised of a plurality of building components. The at least one building component detection sensor device is configured to detect data relating to at least one building component of the plurality of building components. In addition, a building component property determination system includes a processor configured to execute instructions stored in memory to determine one or more properties of the at least one building component based at least in part on the data detected by the at least one building component detection sensor device.

Abstract: This invention pertains to a fluid operated valve whereby the valve open or closed status is controlled by the fluid flowing in the valve. The valve geometry is such that it makes use of the fluid and the prevailing fluid flow characteristics to assert control over the period of the opening and closing events and subsequent mass discharge through the valve during these events. Valve geometry is used also to reduce the relative velocity between the valve body and the moving element as the moving element approaches the fully open or fully closed position.

Abstract: This invention pertains to the vapourization of liquids or liquified gases off a heated surface. The invention forces the liquid to maintain thermal contact with the heated surface by imparting acceleration on the liquid and delivering the liquid into acceleration wells or liquid trap on or in the heated surface.

Abstract: A homogeneous or pre-mixed charge auto-ignition engine comprising two interconnected chambers (20, 30) one of which is the combustion chamber (20) and the other (30) containing the power transmitting member (31). Between the two chambers (20, 30) there is means to control the pressure movement (40, 41, 43, 46) therebetween when the air/fuel mixture in the combustion chamber (20) ignites so that the force of combustion is effectively applied to the piston (31).

Abstract: A lean burn auto-ignition internal combustion engine which has a combustion volume which includes two parts one entering into the other, the volume of the second part being variable by control means (34) which takes into account the various operating parameters of the engine to ensure that auto-ignition takes place at a time which ensures maximum benefit from the ignited fuel charge. In a piston engine there is a secondary cylinder (30) and piston (31) entering into the main cylinder (10), the piston in the secondary cylinder being continuously movable to vary the compression ration of the combustion volume defined by the two pistons (11, 31) so that ignition takes place at a position of the movement of the main piston to ensure maximum utilization of the power generated by the ignited charge.

Abstract: This invention provides a mechanical device which can be easily positioned around an object to be moved, such that the object is securely held by the device and able to be easily moved to a new location. The invention is a lifting device which comprises an open chassis arrangement such that the object to be lifted can enter the device, and as it does so at least one moveable arm will engage and secure the object within the lifting device.
