Abstract: A system for visualization and quantification of ultrasound imaging data according to embodiments of the present disclosure may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to estimate axial and lateral velocity components of the fluid flowing within the bodily structure, determine a plurality of flow directions within the image based on the axial and lateral velocity components, differentially encode the flow directions based on flow direction angle to generate a flow direction map, and cause the display unit to concurrently display the image including the bodily structure overlaid with the flow direction map.

Abstract: Ultrasound imaging systems and methods for generated clutter-reduced images are provided. For example, an ultrasound imaging system can include an array of acoustic elements in communication with a processor. The processor is configured to activate the array to perform a scan sequence to obtain a plurality of signals, identify off-axis signals from the plurality of signals by comparing the right subaperture and the left subaperture, and create a clutter-reduced image based on the comparison. Because off-axis signals are more likely to create image clutter, reducing the influence of off-axis signals on the image can therefore improve the quality of the image. Accordingly, embodiments of the present disclosure provide systems, methods, and devices for generating ultrasound images that have reduced or minimized clutter, even for images obtained using arrays that do not satisfy the Nyquist criterion.

Abstract: Systems and methods for trusted gaming transactions using blockchain technology, including creating a smart contract defining terms of a particular gaming transaction using a blockchain, activating the smart contract once a threshold amount of game tokens are purchased by participants, and providing a secure game token transferring interface and platform configured to utilize a blockchain protocol to verify ownership and authenticity of the game tokens prior to enabling transferring of the game token from one participant to another participant. A status of the event is monitored using the smart contract, and a payout is initiated to a digital wallet of one or more winning participants by the smart contract upon the occurrence or non-occurrence of a triggering event.

Abstract: A method of maintaining a safe free chlorine level in a body of water for recreational use where the free chlorine level at a harmful level comprises determining if the free chlorine level in the body of water is above a safe level and adding sufficient DMH to the body of water to bring the free chlorine down to a safe level.

Abstract: A filterwell cartridge having ports for dispensing a dispersant directly into a filterwell of a hot tub, spa or the like with the filterwell cartridge peripherally and postionally supportable in a quick release mode through facial engagement of compound surfaces located on opposite sides of the filterwell cartridge.

Abstract: A floating dispenser holder having a platform supporting a dispensing cartridge in a dispensing condition and a canopy extending over the dispensing cartridge located on the platform.

Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein enable executable code of a hardware security platform (HSP) circuit to communicate with a hypervisor in a separate processor. The hypervisor generates and manages virtual machines. The HSP code comprises trusted platform module (TPM) logic, that processes TPM commands received via the hypervisor, and in response to the processing, communicates security information (e.g., measurements, keys, authorization data) with the virtual machines via the hypervisor. The TPM logic receives security information related to a virtual machine from the hypervisor and stores the security information in non-volatile memory of the HSP circuit, where security information from a particular VM is distinguishable from security information from another VM in the HSP memory.

Abstract: The methods and systems described herein can be used for generating a graphical representation, such as a heatmap, for displaying and visualizing a given metric associated with one or more distributed resources in a distributed environment. A heatmap generally refers to a graphical display of data in which values are located in a matrix and indicated by the intensity of a color, hue, shading or some other gradient, or by geometric shape or other format. Heatmaps provide a way of visualizing metrics of a large number of resources easily for capacity management, among other uses. Generally, and as set forth in greater detail, the disclosed subject matter provided herein includes methods and systems for collecting, processing, and visualizing operational data of distributed resources via a heatmap by a monitoring system in a distributed environment.

Abstract: A method of maintaining a safe free chlorine level in a body of water for recreational use where the free chlorine level at a harmful level comprises determining if the free chlorine level in the body of water is above a safe level and adding sufficient DMH to the body of water to bring the free chlorine down to a safe level.

Abstract: A method and dispenser for maintaining a body of water in a swimming pool free of algae with the dispenser water mateable to a surface within a pool pump basket to deliver at least one dispersant to the pool water flowing through the pool pump basket

Abstract: A filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

Abstract: A two-part dispensing device for a pool having a dispensing saddle with a static port therein for continual delivery of a first dispersant and a hold for floatingly supporting itself and an exchangeable dispensing pod therein with the dispensing pod having a dynamic port and a static port for a continual delivery of a dispersant wherein the static port delivery of a dispersant maintains the pool at a safe level when there is no human bather load on the pool and the condition of the disperant in the dispensing pod can be determined by the orientation of the dispensing saddle and the dispensing pod in the pool.

Abstract: A method of maintaining a body of water in a usable condition through a comparative measurements of total chlorine and free chlorine in the body of water to determine if a synergistic chemical combination exists within the body of water that can effect the amount of chlorine to add to the body of water.

Abstract: A system for limiting the flow from a dispensing valve when a dispensing cartridge is replaced with the system including a dispenser cartridge with a cam and a water socket with a flow limiter therein that is activeable in response to the position of the dispenser cartridge in the dispensing valve and operable in response to an upstream fluid pressure in the dispensing valve.

Abstract: A method and device for maintaining a body of water in a sanitized condition wherein the body of water is free from a source of bicidal metal ions and free from bromide or bromine compounds that can sanitize the body of water, the method including that steps of maintaining a chlorine level in the body of water at a level of between 1 ppm and 1.0 ppm; introducing a non-chlorine based oxidizing agent into the body of water wherein the chlorine level in combination with the oxidizing agent is selected so as to be insufficient to sanitize the body of water, and introducing a compound having a hydantoin ring therein into the body of water whereby the combination of the chlorine and the oxidizing agent sanitize the body of water without the presence of a source of biocidal metal ions to supplement the chlorine.

Abstract: A filterwell cartridge holder mountable within a hot tub filterwell with the filterwell cartridge holder having a handhold on one end and a feed pipe connector on an opposite end that is attachable to or removable from a filterwell feed pipe with the filterwell cartridge holder engaging and supporting dispensing cartridges thereon to maintain the dispensing cartridges in a dispensing mode within the filterwell.
