Method and apparatus for monitoring states of consciousness, drowsiness, distress, and performance

Apparatus and method for the early detection of increased performance impairment, incapacitation or drowsiness of a person, particularly of a person gripping an object such as a steering wheel. A wrist band is worn by the person and an electrical sensor is pressed against the person's skin by the band to sense physiological conditions by detecting various parameters at the wrist and analyzing them to provide an indication of the onset of drowsiness in the person. Some of the parameters analyzed include EMG, temperature, response to stimulation and muscular activity at the wrist. A description of a shock-absorbing wrist monitor is disclosed.

Method and means for capture and long-term sequestration of carbon dioxide

InactiveUS20090081096A1High heat of reactionHigh regeneration energyCombination devicesGas treatmentSolubilityAmbient pressure
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.

Grappler control system for a gantry crane

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. Furthermore, the grappler automatically stops when positioned appropriately to permit a latching mechanism to engage the object for lifting. 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.

Environmental protection urea-formaldehyde resin and preparation method thereof

A novel environmental protective urea-formaldehyde resin and a preparation method belong to the field of wood processing adhesives. The urea-formaldehyde resin is formed by the reaction of urea, formaldehyde, aldehyde, one or more stabilizers and modifier according to the route of weak base-weak acid-weak base. The method firstly controls the F / U feed ratio, the pH value and the temperature during the reaction process to reduce the content of free formaldehyde in the resin; then the aldehyde is introduced to allow the resin to generate the stable alkyl ether (-(CH2)n-O-(CH2)n-) structure, thus reducing the content of methylene-ether bond (-CH2-O-CH2-) in the resin structure, simultaneously reducing the using amount of the formaldehyde and further greatly reducing the release amount of the formaldehyde during the using process of a plate from the two aspects; in addition, the introduction of a long chain and polyaldehyde can ensure the resin to have great bonding strength and water resistance. The urea-formaldehyde resin which is prepared by the invention has the advantages of low content of free formaldehyde, simple process, low cost, etc., the release amount of the formaldehyde of the plate which is prepared by using the adhesive achieves the E0 level standard, and the high bonding strength can be maintained after being boiled in hot water.

Phosphorus removing agent containing inorganic mineral and application method thereof

The invention relates to a phosphorus removing agent containing inorganic mineral and an application method thereof. The phosphorus removing agent contains 50-75% of an aluminium-containing compound, 15-30% of an inorganic mineral adsorbent and 10-20% of an iron-containing compound, and also can be compounded with a B component. By the use of the phosphorus removing agent, inorganic phosphorus and organic phosphorus in wastewater are removed effectively. By the addition of the inorganic mineral adsorbent, phosphates are fully adsorbed, and the inorganic mineral adsorbent can be combined with iron hydroxide and dried aluminium hydroxide gel generated during the reaction. Thus, more phosphates and pollutants in water can be adsorbed to form larger floc, and settling and flocculation processes are accelerated. Through the synergistic effect of substances, a better phosphorus removing effect is achieved. The phosphorus removing agent has a very good effect of processing orthophosphate, polyphosphates and organic phosphorus and especially has a function of efficiently removing organic phosphorus. In addition, the application method of the phosphorus removing agent is simple.
