Abstract: A business method includes imaging documents with an imaging device placed at a location. Media usage is monitored over a cellular network. Upon the media reaching a predetermined level, workers provide additional media. Workers exist in the “gig” economy and have preplaced media. No longer do users change or swap media in media trays. Packaging materials bundle the media. For use, only a portion of the packaging materials is opened thereby revealing an end of the media. Both the packaging materials and the exposed media are inserted into a reusable media shell in a manner making the media available for picking by the imaging device. Other embodiments are envisioned.

Abstract: The present disclosure relates to methods and intermediates useful for preparing a compound of formula I: or a co-crystal, solvate, salt or combination thereof.

Abstract: An example breath collection and sampling device disclosed herein comprises a cartridge housing having a breath capture module, and a rotary valve operatively coupling a mouthpiece with the breath capture module. The rotary valve can have an open position where breath of a user can pass through the rotary valve, across capture sites of the breath capture module, and into a vacuum port, and a closed position for sealing the breath capture module from fluid passing through the rotary valve, while allowing the breath capture module to be exposed to a reagent for subsequent analysis of contents within the captured breath.

Abstract: Systems and techniques for detecting a target substance, such as THC, in a breath constituent sample are provided.

Abstract: Methods, systems and techniques for the accurate measurement of breath-borne biomarkers are disclosed. Such methods, systems and techniques may be used for the purposes of detection and/or measurement in breath samples of biomarkers, e.g., biomarkers relating to a disease or a physiological condition.
