Abstract: An example fluid system can include a fluid noise suppressor having a resilient insert having an outer surface; wherein the resilient insert can be operable to dampen a fluctuation of a total pressure about a mean static pressure, providing effective noise reduction that without the resilient insert, would have occurred in the flowing fluid with the fluctuation; and wherein the mean static pressure can be between about 100 psig to about 10,000 psig.

Abstract: A fluid system can have a water hammer arrestor including a resilient insert having an outer surface. The resilient insert can be operable to dampen a pressure spike in the fluid that exceeds a static pressure range, providing effective water hammer arrestment that without the resilient insert, would have occurred in a flowing fluid with the pressure spike. The static pressure range can be up to about 100 psig.

Abstract: A dispenser comprising a body with a front side and a back side with the front side movably attached to the back side by a hinge, wherein the hinge includes pin receiving openings and the hinge is configured to move the front side between an open position and a closed position; and a locking device including pins and a pin housing for each of the pins and being configured to allow respective movement of the pins between a first pin position and a second pin position; and a dispenser key configured to magnetically move the pins from the first pin position to the second pin position to allow the front side to move from the closed position to the open position.

Abstract: Aspects of the present disclosure relate to systems and methods for harvesting energy from the pressure ripple of a fluid system. In an example embodiment, a system comprises a housing; a piezoelectric stack in fluid communication with a pressure ripple of a fluid system and configured to generate a piezoelectric voltage and an associated piezoelectric current in response to pressure ripple characteristics, wherein the piezoelectric stack is disposed within the housing; and regulatory circuitry in electrical communication with the piezoelectric stack and configured to convert the piezoelectric current into DC voltage.

Abstract: A syntactic foam of a host matrix and inclusions dispersed in the host matrix, wherein at least a portion of the inclusions include microspheres containing a charge gas and having an internal pressure of greater than 0.1 MPa.

Abstract: The inventions include an adaptive vibration absorber (AVA) and variation thereof including variations in methods and systems of usage. An exemplary AVA may operate adaptively over an appropriate relatively wide bandwidth or frequency range in vibration absorption without adding energy to the system and the problems associated with such energy addition. Further, the exemplary AVA may be of low cost as well sa lightweight and compact.
