Abstract: Plant support trays each have a plant-supporting surface and a series of grooves or channels extending below the pot-supporting surface. The plant support trays have integral water runoff troughs that receive runoff water from the grooves or channels. The plant support trays may be configured to provide gravity-based drainage while supported on a horizontal frame or rack or platform, or may be configured to provide drainage while supported on an angled frame or rack or platform.

Abstract: Air flows across an air-liquid interface such that liquid desiccant flowing through the interface absorbs water from the air and is thereby diluted to form an output stream. The output stream is circulated through an electrodialytic stack having a central ionic exchange membrane and first and second outer ionic exchange membranes. A redox shuttle loop circulates around the first and second outer ionic exchange membranes. A voltage is applied across the electrodialytic stack, which regenerates the liquid desiccant.

Abstract: Disclosed herein are medical device systems, and methods thereof, for automatically detecting access to a medullary cavity. Embodiments include intraosseous access systems with sensing obturators, configured to detect a change in modality, e.g. pressure, oxygen saturation, electrical impedance, etc. at a distal tip thereof. Signals can be transmitted to a control logic that can modify the activation of a driver in response. Signals can be transmitted by way of wired or wireless communication. In an embodiment, signals can be transmitted through conductive polymer material that forms the obturator and allows the obturator to be flexible enough to mitigate accidental needle stick injuries.

Abstract: A cloud-based management system for distributed datacenters provides remote management of the datacenters from terminals at various locations. A virtual cloud-based operating system facilitates a transparent system call architecture, permitting subscribers to deploy, configure and manage operations at machines operating on different local operating systems. The virtual operating system can canonicalize available resources into a namespace to expose the resources as files at terminals. Asynchronous execution of subscriber commands across a group of target machines is provided with a notification procedure to control bandwidth and resource allocation. A file distribution model without a central controller for a group of target machines is provided to alleviate interaction with the management cluster for file distribution.

Abstract: In one embodiment, a diagnostic system includes an instrument coupled to a client device and having at least one sample processing bay. The diagnostic system has a software architecture including instrument software (ISW) associated with the instrument. The ISW receives an assay definition file (ADF) that has a control file and an assay analysis module (AAM) file. The processing bay prepares and senses the sample according to parameters in the OPUS file and then generates sensor scan data. The diagnostic system then analyzes the sensor scan data and prepares a report according to the AAM file.

Abstract: Systems and methods provide for intelligently switching between cloud processing mode and edge processing mode based on a variety of criteria, such as the desired eye-tracker settings (e.g., minimum tracker rate, ideal tracker rate, and processing mode) and the available network capabilities (e.g., latency, bandwidth, and the like). The criteria used for determining whether buffered cloud processing is viable include such parameters as upload bandwidth, tolerable processing delay, buffer drain rate, buffer fill rate, and maximum session duration. The cloud processing system may be used instead of available edge processing in cases where there are benefits to doing so, e.g., the cloud processing system provides added functionality, such as improved data analytics.

An assembly comprising a cap prefilled with a fixative solution, a valve, and a container for storing a tissue sample are provided. The valve is adapted to be situated between the cap and the container such that fluid can flow from the cap into the container when the assembly is upright, but the fluid cannot backflow from the container to the cap when the assembly is horizontal or inverted.

Abstract: A magnetic resonance imaging (MRI) system having a resistive, solenoidal electromagnet for whole-body MRI may include ferromagnetic material within an envelope of the electromagnet. The system can be configured to have a field strength of at least 0.05 Tesla and its main electromagnetic field can be generated by layers of conductors instead of bundles. Certain electromagnet designs may be fabricated using non-metallic formers, such as fiberglass, and can be constructed to form a rigid object with the layers of conductors by fixing all together with an epoxy. The electromagnet may be configured to have two separated halves, which may be held apart by a fixation structure such as carbon fiber. The power supply for certain electromagnets herein may have current fluctuations, at frequencies of 180 Hz or above, of at least one part per ten thousand without requiring an additional current filter.

Each of the first and second valve devices can include first and second fluid pathways and first and second valve members respectively positioned at the first and second fluid pathways. Both the first and second valve members can have an open position that permits fluid flow and a closed position that prevents fluid flow along the first and second fluid pathways past the first and second valve members. The coupling mechanism can couple to each of the first and second valve members. When the valve assembly is actuated, the coupling mechanism can be configured to transition one or both of the first and second valve members between the open and closed positions.
