14066 results about "Odor" patented technology

An odor, or odour, is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive by their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor.

Method for controlling multiple indoor air quality parameters

The present invention provides an improved method and system for controlling an HVAC system for managing multiple indoor air quality (IAQ) parameters. An acceptable range is defined for each of the IAQ parameter. The parameters are then monitored by sensors within a controlled space. The parameters may comprise temperature, humidity, smoke, radon, VOCs, carbon dioxide, carbon monoxide, particulates, hydrocarbons, oxygen, ozone, and odors. The invention maintains the IAQ parameters within their respective acceptable ranges by automatically manipulating certain HVAC system functions including heating, cooling, humidification, dehumidification, ventilation, addition or removal of materials or compounds which affect IAQ parameters, airflow volume and air recirculation. In one embodiment of the invention, a non-HVAC-specific venting system is used to augment HVAC adjustment of airflow volume and air recirculation. This may include bathroom, kitchen and attic venting systems as well as whole-home vacuum systems.

Special biological fish-fertilizer for aquaculture and preparation method thereof

The invention discloses a special biological fish fertilizer and a preparation method for the fertilizer used in aquiculture; wherein, the biological fish fertilizer mainly comprises raw materials as follows: microbiological preparation, inorganic fertilizers, fermentation organics, micro-mineral amino acid chelate, mineral composites, and water quality improver. The preparation method for the special biological fish fertilizer in aquiculture comprises steps as follows: microbiological preparation is produced; fermentation organics is then produced, and the micro-mineral amino acid chelate is produced, eventually the finished products are made. The special biological fish fertilizer has the advantages of limiting the growth and reproduction of the harmful algae, promoting the large-scale growth and reproduction of the suitable food for fish, effectively improving the water quality and purifying the water environment, strengthening the fish immunity, reducing the diseases, reducing cost due to the small use level, convenient use, mild odor, no pollution to the water, and environment protection. By combining the modern bioengineering technique, low-temperature drying technique, spray-drying technique, and super-fine crushing techniques, the preparation method has the advantages of stable quality for the fish fertilizers and lower overall cost.

Systems, methods and articles for enhancing wellness associated with habitable environments

Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and / or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a “wellness” or sense of “wellbeing” provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for “jet lag” or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and / or facility personnel, as is instruction, and surveys, including assessing wellness.

Anaerobic digestion handling method for restaurant garbage

The invention provides a method for resourceful treatment of restaurant garbage, which is characterized in that the restaurant garbage is completely degraded after treatment with the working procedures of oil separating, preliminary selecting, mechanical crushing, hydraulic pulping, slurry blending, anaerobic fermentation and oxygen-control composting, finally the marsh gas is decomposed via anaerobic digestion and is utilized as energy after desulfurization treatment; the high-quality organic manure is produced from the biogas residues via oxygen-control composting; the separated oil can be recycled as the regenerated industrial raw oil; the wastewater generated in the treatment process can be recycled, and finally the redundant wastewater reaching the standard is discharged after biochemical treatment; and the odor generated by the garbage in the treatment process is directly discharged after reaching the standard via biofiltration treatment, thus the restaurant garbage can be transformed into the clean regenerated energy of electric power and the pollution-free organic manure to completely realize resourceful treatment of restaurant garbage. The resourceful treatment of restaurant garbage has the advantages of innocuity, no peculiar smell, no secondary pollution during the treatment process and realization of harmless and resourceful treatment of restaurant garbage.
