Abstract: A microfluidic lab-on-a-chip (LOC) device, microfluidic systems, and associated methodology are described that allow for intelligently collecting environmental DNA (eDNA) and their associated metadata. Optical spectroscopy is integrated with filtration membranes on the microfluidic device. The microfluidic LOC device and systems can be used for selectively capturing targeted species based on optical characteristics and for recording relevant metadata on eDNA acquired by the filtration membranes.

Abstract: A display system comprising a steerable display having a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees, the steerable display positioned for a user. In one embodiment, the steerable display is positioned for the user's fovea.

Abstract: Systems and methods for generation and use of document analysis architectures are disclosed. A model builder component may be utilized to receiving user input data for labeling a set of documents as in class or out of class. That user input data may be utilized to train one or more classification models, which may then be utilized to predict classification of other documents. Trained models may be incorporated into a model taxonomy for searching and use by other users for document analysis purposes.

Abstract: A mounting assembly is provided for mounting a sheave roller to a ladder-type cable tray. The cable cables can be laid on the cable tray for routing through a building. The mounting assembly includes first and second housing parts which are moveable relative to each other. The housing parts are attached to respective rungs of the cable tray. A lock prevents the relative movement of the housing parts relative to each other once the mounting assembly is engaged with the cable tray. The sheave roller is rotatably attached to the one housing part. This quickly and easily installs the sheave roller on the cable tray.

Abstract: A mounting assembly is provided for mounting a product, for example a cable feeder, accessory or roller, to a cable tray. The cables can be laid on the cable tray for routing through a building. The mounting assembly includes an elongated rod, first and second arms extending downwardly from the rod and attached to the cable tray, a ratchet mechanism attached to one of the arms, and an attachment member on the other of the arms. The ratchet mechanism includes a ratchet and an extendable and retractable strap. The strap can be extended around the bottom of the cable tray and attached to the attachment member. This quickly and easily installs the product on the cable tray.

Abstract: There is disclosed a storage and handling system for large flexible sheets such as printing plates. The system includes a rack which is of generally conventional construction having upright end standards or vertical posts that suspend at least one horizontal shelf. The shelf is provided with a plurality of horizontal tracks, each of which has a central, open channel along its bottom surface, to provide a slide receptacle. A T-bar is slidably and removably mounted in the open channel of each of these tracks. The T-bar has a plurality of apertures which are spaced, preferably at regular and predetermined distances, through its upright flange. These apertures receive removable two-ended hooks. The opposite ends of the hooks are inserted in apertures along one side edge of each of the printing plates.

Abstract: This invention relates to display units for cassettes and like articles.The display unit comprises a vertical support spindle on which is rotatably mounted a plurality of spaced trays. Display sections are formed by adjacent trays for receiving the cassettes and the cassettes are released by axial movement of the adjacent trays on the support spindle.According to the invention adjacent trays are rotatable relative to each other to produce the necessary axial movement and locking means is provided along the length of the spindle to prevent unauthorized operation.
