A system includes a processor component, a communications interface component, an event definition component and an event management component. The communications interface component may be operative to establish a bridge connection among a plurality of communication devices. The event definition component may be operative on the processor component to define the parameters of an event, the event indicative of an unplanned happening. The event management component may be operative on the processor component to recognize a triggering of the event and cause the communications interface component to establish the bridge connection among the plurality of communication devices upon the triggering of the event. Other embodiments are described and claimed.

Abstract: A foam dispensing device mixes a foamable liquid with compressed ambient air and dispenses a foam having the desired liquid-to-air ratio at an early time during foam dispension. The device, which has a vertical liquid conduit and a restricted air passage leading to a mixing chamber, also has two one-way pressure-activated valves to delay the flow of air and to accelerate the flow of liquid to the mixing chamber when the compressed air is introduced. The first valve is located in the liquid conduit below the air passage to prevent liquid from flowing down the tube, thereby accelerating the flow of liquid when the compressed air is introduced. The second valve is located above the air passage to delay air flow.

Abstract: A foam dispensing device mixes a foamable liquid with ambient air and dispenses a foam having a relatively constant ratio of liquid to air even during rapidly repeated foam dispension. The device contains a passage for foam return from a foam conduit to a liquid reservoir having one-way valve means to permit flow only in the direction from the foam conduit to the liquid reservoir during operation of the foamer, and a means of separating the inlet to the air passage from the outlet of the foam return passage to prevent flow of foam through the air passage during rapid, repeated foam dispension.

Abstract: A pad is used in shifting a patient from one bed, or other horizontal surface, to another. The pad is formed of a sealed, elongated, and flattened enclosure of a flexible, puncture-resistant material and contains, sealed within the enclosure, a lubricant to reduce the friction between the inside surfaces of the enclosure.

Abstract: A device for use with foamable liquids includes a reservoir adapted to contain a quantity of a foamable liquid and an air pump for supplying air to be mixed with the foamable liquid to form a foam. The foamable liquid reservoir is isolated from the air supplying pump. A mixing chamber is provided in which the foamable liquid and air from the air supplying pump can interact to create the foam. A first passage leads from the reservoir of foamable liquid to the mixing chamber and a pump is provided for pumping the foamable liquid from the reservoir through the passage to the mixing chamber. A second passage is provided from the air supplying pump to the mixing chamber to introduce air into the mixing chamber.

Abstract: The sense of touch is enhanced by: (1) placing two layers of a pliable, elastic material between the fingertips and the object being touched; (2) maintaining the coefficient of kinetic friction between the two layers at less than the coefficient between the fingertips and the top layer and less than the coefficient between the object being touched and the bottom layer; and (3) moving the fingertips over the object being touched separated by the two layers of material.

Abstract: An apparatus enhances the sense of touch when placed between the fingertips of the user and the object being touched. The apparatus comprises a liquid lubricant inside a sealed enclosure. The enclosure is formed of a pliable, elastic material having a wall thickness of about 0.005 to 0.020 inches. The liquid lubricant is present in an amount sufficient to fully coat the interior of the enclosure, but which also permits the enclosure to be flattened with at least about 75 percent of the surface area of one side in contact with the other side.

Abstract: This foam dispenser includes a flexible container for foamable liquid, having a discharge opening at the upper end. A porous member is housed in the discharge opening and a conduit communicating with said porous member extends downwardly into the interior of the container. A flow directing valve system within the conduit determines the path of air and liquid through the conduit and the porous member during manual pressurization and depressurization of the container. The foamable liquid and air are isolated from each other by a bag member disposed within the container.

Abstract: This foam dispensing device includes a flexible container for foamable liquid, having a discharge opening at one end. A foam producing assembly is housed within the container, the assembly including a self-supporting porous member of rigid material held within the neck of the container and a tubular member of non-porous material having one end extending into the porous member and the other end extending into the interior of the container. Fluid mixing within the porous member is facilitated by flow restriction, and an air return facilitates rapid container recovery.

Abstract: A plunger assembly is longitudinally movable within an outer tube having a lower closed end. The plunger assembly includes a plunger tube and a resilient piston-valve plug seated in the inner end thereof. The piston-valve plug has frictional sealing engagement with the inner walls of the outer tube, has a slit therethrough for permitting the flow of clear liquid from the lower end of the outer tube into the plunger tube when the plunger tube is moved inwardly of the outer tube, and has a port therethrough for permitting the return flow of air into the space in the outer tube below the plug when the plunger tube is moved outwardly of the outer tube. A filter element is seated in the plug to filter liquid prior to flow through the slit.

Abstract: A foam dispensing device having a foaming member and valve system in a flexible container designed to produce a quality foam when the container is pressurized regardless of the position of the container.

Abstract: An apparatus enhances the sense of touch when placed between the fingertips of the user and the object being touched. The apparatus comprises a liquid lubricant inside a sealed enclosure. The enclosure is formed of a pliable, elastic material having a wall thickness of about 0.005 to 0.020 inches. The liquid lubricant is present in an amount sufficient to fully coat the interior of the enclosure, but which also permits the enclosure to be flattened with at least about 75 percent of the surface area of one side in contact with the other side.
