  • System and method for outage avoidance
    Patent number: 8224926
    Abstract: Disclosed are systems and methods for outage avoidance in connecting to a remote system. The systems and methods dynamically adjust the number of requests allowed to attempt to access the remote system, resulting in a more efficient use of resources and an improved user experience.
    Type: Grant

  • System and method for accurate contactless measurement of the resistivity of a test material
    Patent number: 5386196
    Abstract: A system (10) accurately measures the resistivity of a material (12) via capacitive coupling without contact with the material (12). A transmission electrode (14a) sends signals through the material (12) to a reception electrode (14b). An oscillation mechanism (16) forwards a periodic signal at a predetermined frequency f to the electrode (14a), and a detection mechanism (18) receives a resistivity signal from the electrode (14b), which signal is proportional to the resistivity of the material (12), and translates the resistivity signal into a resistivity value for the material (12). The oscillation mechanism (16) comprises an oscillator (21) connected through a transformer (T1) to a quarter-wavelength stub (24), which feeds an excitation signal to the transmission electrode (14a). The detection mechanism (18) comprises a detector (31) connected via a transformer (T2) to a quarter-wavelength stub (26), which is directly connected to the reception electrode (14b).
