Abstract: An exemplary method includes a computing system receiving an audio message generated by a first device, determining a physical location of the first device when the audio message is generated, and associating the audio message with the physical location. The method further includes the computing system identifying a target recipient of the audio message, identifying a second device associated with the target recipient, and providing, based on a proximity of the second device to the physical location, the audio message to the second device.

Abstract: An architecture for unifying communication networks and protocols via a network of centralized servers, using multiple processes to intelligently route messages among various devices. Through Application Programming Interfaces the server can connect to Internet-ready devices, cell phones, and land-line phones.

Abstract: A plural component spray gun (1) is designed for spraying quick setting materials such as foams, polyurea and the like. Towards this end, the gun (1) is designed so as to be easily serviceable with a minimum of tools. For example, the side seal cartridges (18) and (20) may be installed and removed without tools by removing the retaining ring (9) and then extracting them from the fluid housing (11). Those cartridges (18) and (20) are easily disassembled and cleaned. Similarly, the fluid housing (11) may be removed from the handle/body (1) by unscrewing the lock ring (7) by hand.

Abstract: A plural component spray gun (10) is designed for spraying quick setting materials such as foams and the like. A mix module (14) plastic material provides at least twice the life with ½ the wear of currently marketed mix modules and is made of poly ether ether ketone reinforced with graphite and PTFE lubricants.
