    摘要: Non-linear distortions, called glitches, occur in radio receivers when automatic gain control (AGC) is employed for regulating the dynamic range of the received signal. It is proposed to determine (S1) the occurrence of a glitch caused by operation of the AGC mechanism, and estimate (S2) a representation of how energy of a signal transient associated with the glitch is transferred by digital filter(s) in the receiver. The radio signal is then detected (S3) at least partly based on the estimated representation. In this way, the adverse effects of the glitch can be mitigated and detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved.

    摘要: An oilfield material reservoir is disclosed. The oilfield material reservoir has a body, the body having an upper end, a lower end, a sidewall extending between the upper and lower ends, the sidewall defining a recess within the body, an opening defined by the upper end, and a first orifice defined by the lower end. The oilfield material reservoir is also provided with a metering gate connected to the body at the lower end. The metering gate has a base having a second orifice aligned with the first orifice, and a knife gate connected to the base. The second orifice has a substantially trapezoidal shape. The knife gate is configured to slidably cover the second orifice. A method is also disclosed for controlling a discharge rate of oilfield material within the oilfield material reservoir by adjusting a metering open area of the second orifice according to mathematical modeling equations.
