  • Patent number: 11938067
    Abstract: A patient containment system for securing a patient to a patient transport apparatus, comprising a first lower strap and a second lower strap. Each of the first lower strap and the second lower strap have a thigh region, a waist region, and a connection region arranged between the thigh region and the waist region. A first connector is coupled to the connection region of the first lower strap. A second connector is coupled to the connection region of the second lower strap, and is configured to releasably attach to the first connector to at least partially limit movement of the first lower strap relative to the second lower strap. The connection region defines a connection width, and the thigh region defines a thigh width larger than the connection width.

  • Publication number: 20210031571
    Abstract: A tire deflation and inflation system for a vehicle. The system includes a unit bearing having a plurality of wheel flanges for mounting a wheel thereto. The unit bearing is configured to receive therein a portion of an axle of the vehicle. A wheel hub is mounted to the unit bearing. An air chamber is defined by the unit bearing. In response to positive air pressure generated by an air pressure source, air flows through the air chamber to a tire of the wheel mounted to the unit bearing to increase air pressure of the tire. In response to negative air pressure generated by venting the system to atmosphere, air is drawn out of the tire through the air chamber.

  • Publication number: 20120163930
    Abstract: A cutting tool abnormality sensing apparatus is disclosed. The apparatus includes an image pickup device for taking individual images of teeth of the cutting tool. The apparatus further includes a triggering mechanism for triggering the image pickup device each time a tooth passes along a field of view of the image pickup device. One or more light sources are provided to illuminate the cutting tool. Further, the apparatus includes an image processor to process one or more criteria in the individual images for quantifying an extent of abnormality in the cutting tool.

  • Publication number: 20070295505
    Abstract: Methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content are described. The methods may include accessing a consortium of microorganisms in a geologic formation that includes a carbonaceous material. They may also include providing a phosphorous compound to the microorganisms. The phosphorous compound stimulates the consortium to metabolize the carbonaceous material into a metabolic product with enhanced hydrogen content. Also, methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content by providing a yeast extract amenment to a consortium of microorganisms is described. The yeast extract amendment stimulates the consortium to metabolize carbonaceous material in the formation into the metabolic product with enhanced hydrogen content.

  • Publication number: 20070261843
    Abstract: Methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content are described. The methods may include accessing a consortium of microorganisms in a geologic formation that includes a carbonaceous material. They may also include providing hydrogen and one or more phosphorous compounds to the microorganisms. The combination of the hydrogen and phosphorous compounds stimulates the consortium to metabolize the carbonaceous material into the metabolic product with enhanced hydrogen content. Also, methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content by providing a carboxylate compound, such as acetate, to a consortium of microorganisms is described. The carboxylate compound stimulates the consortium to metabolize carbonaceous material in the formation into the metabolic product with enhanced hydrogen content.

  • Publication number: 20070248531
    Abstract: Disclosed are strategies for the economical microbial generation of hydrogen, useful as an alternative energy source, from hydrocarbon-rich deposits such as coal, oil and/or gas formations, oil shale, bitumen, tar sands, carbonaceous shale, peat deposits and sediments rich in organic matter through the management of the metabolism of microbial consortia.

  • Publication number: 20070161077
    Abstract: An isolated microbial consortium is described that includes a first microbial consortium having Thermacetogenium phaeum to metabolize a complex hydrocarbon substrate into metabolic products comprising an acetate compound. The consortium also includes a second microbial consortium having a methanogen to convert the acetate compound into a final product that includes methane. Also, a method of increasing production of materials with enhanced hydrogen content. The method includes isolating Thermacetogenium phaeum from geologic formation water, culturing the isolated Thermacetogenium phaeum to increase the Thermacetogenium phaeum population, and introducing a consortium of the cultured Thermacetogenium phaeum, which may include spores of Thermacetogenium phaeum, into a hydrocarbon formation containing a complex hydrocarbon substrate.

  • Publication number: 20070078665
    Abstract: A method of transferring an interest in microbial rights associated with a parcel of land. The method includes recognizing a microbial estate that includes the microbial rights, where ownership interests in the microbial estate are separately transferable from other estates associated with the parcel of land, and transferring one or more of the microbial rights of the microbial estate to a party that is not in possession or ownership of the microbial estate. Also, a method of searching interests in a microbial estate, where the method may include identifying a location for a parcel of land associated with the microbial estate, searching records associated with the identified parcel of land, and identifying in the records a name of one or more parties having an interest in the microbial estate. Methods of auctioning a microbial right in microbial property are also described.

  • Publication number: 20060254765
    Abstract: A method to stimulate the biogenic production of a metabolite with enhanced hydrogen content that includes forming an opening in a geologic formation to provide access to a consortium of microorganisms, and injecting water into the opening to disperse at least a portion of the consortium over a larger region of a hydrocarbon deposit. The method may also include measuring a change in the rate of production of the metabolite in the formation. Also, an method to stimulate biogenic production of a metabolite that includes measuring a salinity level of formation water in a geologic formation, and injecting water into the opening to reduce the salinity level of the formation water in the formation. The method may also include measuring a change in the rate of production of the metabolite in the formation.
