  • Patent number: 8916037
    Abstract: An instrument and method for accurately measuring target analyte levels is a gas sample over an extended range. The instrument includes (i) a sensor effective for detecting the analyte, and (ii) a barrier film having limited permeability for the analyte covering the inlet orifice on the sensor for reducing the flux of analyte into the sensor. The method involves (a) sensing the flux of target analyte passing through the barrier film and into sensing contact with the sensor, and (b) reporting a concentration of analyte by multiplying a concentration value previously correlated to the sensed flux by the flux reduction factor of the barrier film.

  • Publication number: 20130005047
    Abstract: A method of calibrating a luminescence lifetime sensing instrument 20 and of interrogating a target-analyte long-decay luminescence probe 120 includes measuring and reporting luminescence lifetime of the probe 120 employing excitation radiation filtered to remove emission radiation, or a starting time tstart delayed by a predetermined decay delay time, or delayed by a predetermined growth delay time, or an ending time comprising the time at which luminescence intensity has decayed or risen a predetermined percentage.

  • Patent number: 8037667
    Abstract: A stalk roll for a corn head row unit has a conical seat and a spherical seat for mounting the stalk roll on a stalk roll driveshaft of a row unit. Each row unit has a drive shaft with a corresponding conical portion and a threaded fastener with a corresponding spherical portion for capturing the stalk roll on the drive shaft between mating conical shaft and stalk roll portions toward one end and mating spherical shaft and fastener portions at the other stalk roll end.
