Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate 'ghosted' radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.

X-ray scanning system and method

In one aspect, methods of sensing are described herein. In some embodiments, such a method comprises disposing a population of luminescent species in a test sample, exposing the test sample to electromagnetic radiation having a wavelength corresponding to an excitation wavelength of the luminescent species, detecting light emitted by the luminescent species within a detection region of the test sample, and correlating the light emitted by the luminescent species within the detection region to a presence or absence of an analyte within the test sample. The luminescent species, in a non-aggregated state, exhibits luminescence blinking and, in an aggregated state, does not exhibit luminescence blinking. Additionally, correlating the light emitted by the luminescent species to the presence or absence of the analyte comprises determining whether the light emitted by the luminescent species within the detection region is blinking luminescence or non-blinking luminescence.

A tailgate topper for a pickup truck tailgate has a transverse horizontally extending cross-bar supported by a pair of vertically movable support members which allow positioning of the cross-bar at a desired height above the tailgate. A plurality of upwardly biased popup blocks are disposed below said cross-bar within the tailgate so exert pressure upwardly against cargo extending between the cross-bar and the popup block.

An override system for use in combination with an automatic air suspension leveling system for a vehicle is provided The override system includes a cylinder having a piston and a piston rod associated therewith. The cylinder is mounted to the chassis so that the piston rod extends from the cylinder so as to be engageable with a control arm of the air suspension leveling system to move the control arm to an up position upon moving the piston rod from a retracted position to an extended position. The piston and the piston rod are actuated by a pressurized fluid source from the retracted position wherein the control arm is maintained in the neutral position to the extended position wherein the piston rod engages the control arm and causes the control arm to be pivoted to the up position so as to open the regulating valve to cause additional air to be introduced into the air spring thus resulting in the chassis being raised relative to the axle. A valve is interposed between the cylinder and the pressurized fluid source for selectively controlling the flow of pressurized fluid to the cylinder. A spring linkage assembly links the axle to the control arm so that the control arm can be independently moved relative to the axle yet sufficiently stiff to transmit force between the axle and the control arm.
