Embodiments of radiographic imaging systems; radiography detectors and methods for using the same; and/or fabrication methods therefore can include radiographic imaging array that can include a plurality of pixels that each include a photoelectric conversion element coupled to a thin-film switching element. In certain exemplary embodiments, thin-film switching element is a metal oxide (e.g., a-IGZO) TFT manufactured using a reduce photolithography mask counts. In certain exemplary embodiments, the thin-film switching element is a metal oxide (e.g., a-IGZO) TFT that includes reduced lower alignment tolerances between TFT electrodes. In certain exemplary embodiments, the thin-film switching element is a metal oxide (e.g., a-IGZO) TFT including a reduced thickness active layer.

A system for securely transporting medications or other items. The system includes a central computer system and a number of lockable relay boxes. Each relay box further includes a software controlled lid unlockable upon authorization from the central computer system, a memory storing a globally unique electronically readable identifier, a sensor that can detect unauthorized forced entry to the relay box, and a display. The system also includes an electronic network over which the central computer system authorizes accesses to the interiors of the relay boxes.

Embodiments of methods/apparatus can transition a DR detector imaging array to low power photosensor mode where a first voltage is applied across the photosensors. Embodiments of methods/apparatus can provide an area radiographic imaging array including a plurality of pixels arranged in a matrix at the imaging array where each pixel can include at least one electrically chargeable photosensor and at least one transistor, row address circuits, signal sensing circuits, and photosensor power control circuitry to maintain a first voltage across photosensors of the portion of the imaging array when the detector is between imaging operations. In one embodiment, photosensor power control circuitry can maintain the first voltage across the photosensors when a power consumption of the signal sensing circuits is less than 1% of the power consumption of the signal sensing circuits during readout of a signal from the portion of the imaging array.
