  • Ionization gauge with emission current and bias potential control
    Patent number: 9383286
    Abstract: An ionization gauge that measures pressure has an electron source that emits electrons, and an anode that defines an ionization space. The gauge also includes a collector electrode to collect ions formed by an impact between the electrons and a gas and to measure pressure based on the collected ions. The electron source is dynamically varied in emission current between a plurality of emission levels dependent on pressure and a second parameter other than pressure. The ionization gauge may also vary various operating parameters of the gauge components according to parameters stored in a non-volatile memory and selected by a user.
    Type: Grant

  • Stripe following in a helical scan device
    Patent number: 4285017
    Abstract: In a helically scanned device, a length of flexible media, with transverse data tracks thereon, is positioned relative to a rotating transducer. The transducer coacts with the media to transduce data therefrom. The transducer is coupled to a piezoelectric bender. Periodically, the instantaneous position of the transducer is monitored and an error signal is generated. The error signal is used to drive the piezoelectric bender so that the transducer follows the data track.
