  • Patent number: 11023724
    Abstract: Methods and systems for determining a status of a hydrocarbon production site are provided. The systems and methods include defining an area about a hydrocarbon well location and obtaining a time series of mobile geolocation data for at least one mobile device located within the area about the hydrocarbon well location. The times series of mobile geolocation data is processed and probabilities that the mobile geolocation data is associated with a drilling activity, a fracking activity, a tie-in activity, and/or an absence of drilling activity, fracking activity, and/or tie-in activity are output. The mobile geolocation data is categorized, based on the probabilities, as being associated with one of drilling activity, fracking activity, or absence of drilling activity and fracking activity.

  • Publication number: 20040029167
    Abstract: The invention concerns a novel regulating COMTII promoter sequence inducible in response to a mechanical or chemical injury, or in response to aggression by a pathogenic agent, in particular bacterial, fungal or viral, or by an insect or a threadworm. The invention also concerns a chimera gene (or expression cassette) comprising the inventive regulating promoter sequence controlling the expression of a heterologous coding sequence and a host organism comprising said chimera gene, transformed plants containing it and the seeds of said transformed plants.

  • Patent number: 5959178
    Abstract: The biosynthesis of lignin in plants is regulated by insertion into the plant genome by altering the plant's ability to synthesise the enzyme O-methyl transferase, an enzyme involved in the lignin biosynthetic pathway. Production of O-methyl-transferase may be enhanced by insertion into the plant genome by transformation of one or more additional copies of the O-methyl-transferase gene or production may be inhibited by insertion of a gene encoding anti-sense mRNA directed against the mRNA encoded by the endogenous O-methyl-transferase gene.

  • Patent number: 4766894
    Abstract: This invention relates to the monitoring of the correct operation of a respirator with single source of energy constituted by a cylinder of pressurized oxygen, to which is annexed a device for connection to a patient. Such monitoring is effected with the aid of a pneumatically operating device which comprises a comparator with adjustable threshold, connected to the mask for connecting to the patient and followed by an amplifier whose output signal takes the binary logic level 1 during the time when the insufflation pressure in the mask is greater than said threshold, and takes the other binary logic level 0 in the opposite case, and a circuit for processing this signal, which triggers off an alarm device if the duration of the time intervals when this latter is at level 1 is too long or too short with respect to a predetermined normal value.

  • Patent number: 4443828
    Abstract: A low voltage circuit breaker with a current sensing unit having a magnetic circuit with three branches, the secondary winding being mounted on the intermediate branch and the primary winding being formed by a conductor selectively passing through one or two of the openings provided between the secondary winding and the outer branches. The circuit breaker comprises an instantaneous electromagnetic trip mechanism and a static long time and short time delay trip unit, the latter unit being governed by a signal attenuated by a rating selection device.
