Abstract: The disclosed invention relates to novel biocompatible firefighting foam compositions that include a deep eutectic solvent. Disclosed are methods of making and using firefighting foams containing deep eutectic solvents, which may also be used in existing fire foam compositions as drop in solvent additives. The deep eutectic solvents may also be used in or as a principle component of surrogate firefighting foam compositions.

Abstract: A sprinkler includes an inlet aperture, an outlet aperture, a body, a conical member, and a deflector. The inlet aperture receives fire suppressant agent at an inlet end of the sprinkler and the outlet aperture is at an outlet end of the sprinkler. The body extends along a longitudinal axis and includes an inner volume forming a fluid flow path between the inlet end and the outlet end of the sprinkler. The conical member is positioned at the outlet end of the sprinkler directs the fire suppressant agent outwards. The deflector receives fire suppressant agent from the conical member and distributes the fire suppressant agent about a service area. The deflector includes multiple tines, which each extend along a corresponding radial axis that is substantially perpendicular with the longitudinal axis. Each tine is offset by an angular amount about the corresponding radial axis.

Abstract: An air-conditioning condensate drain cleaning apparatus is provided. The apparatus includes a housing configured to suspend a condensate drain line cleaning fluid container therein, and a fluid dispensing unit configured to connect the cleaning fluid container to an air-conditioning condensate drain pipe and selectively control the rate at which the cleaning fluid is transferred from the cleaning fluid container to the condensate drain pipe. The fluid dispensing unit includes an elongated tube for transferring a fluid, a drip chamber for viewing the fluid, and a flow regulation clamp configured to control the rate at which the fluid is transferred from the cleaning fluid container to the condensate drain pipe. The housing includes a support member for suspending the cleaning fluid container therein, an elongated slot for viewing the cleaning fluid container, and a pair of apertures and protrusions for removably mounting the front portion to the rear portion.

Abstract: Systems and methods of sample and staining processing including compression and dynamic movement of liquids in a fluidically moving substantially contained liquid bridge perhaps between a hydrophobic wand and a hydrophilic sample support element. Embodiments may include low volume reagent and perhaps even low volume buffer wash in sample processing. In addition, antibodies can be conjugated with nanoparticles and can be used in sample processing. Exposing a sample with or without movement to AC, DC, or even a permanent magnet field may improve staining. Staining with nanoparticle reagents could be quantified using a microscope with a magnetometer below the slide viewing area. The detection of nanoparticles attached to the chemistry may facilitate the quantification of cancerous cells stained in the tissue.

Abstract: A nozzle assembly for encapsulating a gaseous solution in bubbles comprises a discharge tube having a diffuser and a foam solution spray nozzle mounted therein. The discharge tube has upstream and downstream ends. The discharge tube has a front face at the upstream end with a first opening configured to be joined to a gas supply line that provides a gaseous solution and a second opening configured to receive a non-expanded foam solution. The downstream end of the discharge tube is open. A chamber is formed within the discharge tube to receive the gaseous solution at the upstream end and release the gaseous solution through the diffuser into the discharge tube towards the downstream end.

Abstract: The present invention solves many of the problems for the wheelchair bound individual who wants an ergonomically sensible, convenient, yet powerful and stable wheelchair. The Trike's unique power source is provided by a rowing-type motion of the user rather than the less efficient “hand rim” grip or wrist propulsion. Power is generated both in the out rowing stroke and the in rowing stroke through a inventive power drive. The rowing motion significantly reduces the chances for repetitive stress injuries, like carpal tunnel. Furthermore, the rowing motion and movements are designed to facilitate efficient propulsion and steering in combination, to be effected simultaneously. The rowing motion allows the user's full arm strength and full range of motion to assist in the powering of the vehicle.

Abstract: A cannula assembly is removably mountable to a syringe body having a pair of side-by-side chambers; there being an opening into each chamber at a bottom of the syringe. The cannula assembly includes a connector and a dual lumen assembly extending from the connector. The dual lumen assembly includes a pair of tubes defining two fluid paths. The connector includes fluid paths which, when the cannula assembly is mounted to the syringe, place the fluid path of one of the tubes in fluid communication with one of the syringe body chambers and the fluid path of the other of the dual lumen tubes in fluid communication with the other of the syringe body chambers.

Abstract: A combined irrigator-vacuum device includes a pump assembly mountable over a syringe or device body. The device body has a dividing wall which divides the body into a clean chamber and a waste chamber. Openings are formed at the bottom of the body to provide an inlet into said waste chamber and an outlet from said clean chamber. The pump assembly includes a housing and a compressible cover defining a pump chamber. A vacuum valve and an irrigation valve are positioned within the pump chamber above the syringe waste chamber and clean chamber, respectively. The pump is operable such that compression of the cover causes irrigant fluid to be ejected from the clean chamber and release of the cover causes used irrigant to be vacuumed into the waste chamber. The device can be selectively switchable between an irrigation-vacuum mode, an irrigation-only mode and a vacuum-only mode.

Abstract: Systems and methods for placing a vehicle operator into an performance driving position for a particular vehicle by adjusting equipment on the vehicle based on various combinations of biometric parameters of the vehicle operator. In one embodiment, the performance driving position for a particular vehicle is first determined and is stored in a processing device or associated memory. The vehicle operator may enter required biometric parameters into an input device operably connected to the processing device, which in turn calculates the vehicle operator's present location and any movement of the seating elements, controls, and set forth necessary to place the vehicle operator in an performance driving position. The processing device then sends one or more output signals to one or more motors associated with one or more seating elements or controls to adjust such equipment and place the operator in the performance driving position.
