Abstract: A radio frequency (RF) amplifier is disclosed. The RF power amplifier includes a bias circuit, an output-stage circuit and a RF compensation circuit. When a first system voltage is larger than a first voltage threshold value, the bias circuit generates a first current rising slightly. When first system voltage is larger than second voltage threshold value, the RF compensation circuit receives a second circuit rising slightly transmitted from the bias circuit. When the first system voltage is in an operation voltage range, the first current is larger than the second circuit so as to a quiescent operating current of the RF power amplifier is independent of change of the first system voltage. When the first system voltage is larger than a third voltage threshold value, the first current is equal to the second current so as to have the bias current being a zero current to protect the RF power amplifier from over-voltage.

Abstract: A blowout preventer (BOP) lifting apparatus has a reinforced frame and a gate for securing a BOP stack. The frame has a central U-shaped recess for securing a collared portion of the BOP stack. The gate pivotally swings between a closed position on the frame and an open position for installation and removal of the lifting apparatus from the BOP stack. An actuator has a first end connected to a top surface of the frame and a second end connected to the gate for actuating the opening and closing of the gate to the frame. When the gate is in the closed position, three locking pins are inserted into three vertical pinning holes located on the frame, which are aligned with three pinning holes located on the gate. The apparatus may be lifted via cables or other lifting mechanisms attached via lifting eyelets located on each corner of the frame.

At least some of the panels are formed of blow-molded thermoplastic material and have a relatively flat outside face and an inside face including open channels that extend longitudinally and transversely on the panel. A reinforced panel of thermoplastic material is made by blow molding a panel with a thermoplastic material to form a relatively flat outside face and a ribbed inside face, and with elongated channels along upper and lower portions thereof. The panel may be trimmed while it is still warm to open the channels at one end. While the panel is still warm, reinforcing members may be inserted into the elongated channels. The panels may be cooled to shrink the channels onto the reinforcing members.

Abstract: Apparatus for interrupting and/or scanning a beam of penetrating radiation, such as for purposes of inspecting contents of a container. A source, such as an x-ray tube, generates a fan beam of radiation effectively emanating from a source axis, with the width of the fan beam collimated by a width collimator, such as a clamshell collimator. An angular collimator, stationary during the course of scanning, limits the extent of the scan, and a multi-aperture unit, such as a hoop, or a nested pair of hoops, is rotated about a central axis, and structured in such a manner that beam flux incident on a target is conserved for different fields of view of the beam on the target. The central axis of hoop rotation need not coincide with the source axis.

Abstract: A seat belt buckle assembly for resisting unintentional opening during rapid acceleration or deceleration. The seat belt buckle assembly includes a female buckle, a male tongue plate, a pawl assembly, a spring and a load rate sensitive foam member. The female buckle is a casing with an open end that is adapted to receive the substantially planar male tongue plate provided with a slot. The pawl assembly housed within the casing includes a pawl that fits within the slot. The spring disposed between casing and pawl assembly urges the pawl into slot and elastically deforms when subjected to force. The load rate sensitive foam member interposed between spring and pawl assembly transmits load applied on pawl to spring for facilitating compression of spring and therefore unlatching of the buckle in case of gradual loading, but inhibiting involuntary compression of spring by absorbing most of the impulsive loading.

Abstract: A surgical tourniquet cuff that includes a stabilizer component that facilitates application of an overlapping cuff around the limb of a patient. The stabilizer is fixed to the cuff, and requires no tying or similar user manipulation to secure the overlapping cuff in alignment with the underlying cuff. The stabilizer improves the stability of the inflated cuff to prevent sideways shifting motion of overlapping cuff portions as the cuff is applied to the limb. The stabilizer also provides a handle mechanism to enable the user to snugly apply the overlapping cuff around the patient's limb while the overlapping portions remain properly aligned along their long axes. The stabilizer is designed to also facilitate attaching together two tourniquet cuffs end-to-end, with respective bladders overlapping and in proper alignment so that those attached cuffs can be used as a single, extended surgical cuff applied around a patient's limb.
