A game controller according tot the present invention employs scalable force-detecting sensors (e.g., strain gauges, etc.) to measure user manipulation of controller input devices (e.g., joysticks, etc.). The controller incorporates force sensing, rather than motion sensing, to provide the “analog” type inputs to a computer-interactive game. The force required to provide the controller output is adjustable by the user, while the mapping of sensor to game control is determined by user configuration of the controller.

The invention teaches a practical method of recovering CO₂ from a mixture of gases, and sequestering the captured CO₂ from the atmosphere for geologic time as calcium carbonate and provides a CO₂ scrubber for carbon capture and sequestration. CO₂ from the production of calcium oxide is geologically sequestered. A calcium hydroxide solution is produced from the environmentally responsibly-produced calcium oxide. The CO₂ scrubber incorporates an aqueous froth to maximize liquid-to-gas surface area and time-of-contact between gaseous CO₂ and the calcium hydroxide solution. The CO₂ scrubber decreases the temperature of the liquid and the mixed gases, increases ambient pressure on the bubbles and vapor pressure inside the bubbles, diffuses the gas through intercellular walls from relative smaller bubbles with relative high vapor pressure into relative larger bubbles with relative low vapor pressure, and decreases the mean-free-paths of the CO₂ molecules inside the bubbles, in order to increase solubility of CO₂ and the rate of dissolution of gaseous CO₂ from a mixture of gases into the calcium hydroxide solution.

The CO₂ scrubber recovers gaseous CO₂ directly from the atmosphere, from post-combustion flue gas, or from industrial processes that release CO₂ as a result of process. CO₂ reacts with calcium ions and hydroxide ions in solution forming insoluble calcium carbonate precipitates. The calcium carbonate precipitates are separated from solution, and sold to recover at least a portion of the cost of CCS.

A system and process are provided for controlling motion of a grappler of a gantry crane to avoid damaging an object to be lifted. In an embodiment, a speed of grappler movement is automatically reduced when in close proximity to the object.

Normal speed grappler motion is restored when the latching mechanism is fully engaged. In a particular embodiment, the grappler includes a plurality of height sensors at various positions along the grappler to determine the respective height of the grappler above a top of the object. Vertical motion of front and rear ends of the grappler are independently actuated and controlled to permit appropriate control when the grappler and/or the object are not level.

The inventions separate the activated sludge, biochemical reaction stages of the batch treatment process of a sequencing batch reactor from the clarification and sedimentation stages by separating the locations where each process takes place. The separation may be accomplished in a variety of ways including constructing separate basins for each process, installing baffles or other partitions in a single vessel to isolate the areas where each process takes place, or other methods of process separation as are known in the art. In each process, treatment occurs through the performance of a series of operations. The operations are repeated for each batch of wastewater processed by the SBR. In a conventional SBR process, the cycle of operations for clarification and sedimentation are dependent on a preceding biochemical reaction step. However, in the present invention the clarification and sedimentation operations are independent of the biochemical reaction operations. It remains possible to coordinate operations so that the process cycles are coincident, however the benefits of the invention are more readily realized by the practice of independent operation.
