Abstract: An accountability and identification system includes multiple touch sensors and at least one instrument. At least one of the touch sensors is a personal identification touch sensor having user information on a unique user stored in the memory. One or more touch sensors may be a data touch sensor having user information on a unique group of users stored in the memory. Immediate danger to life and health (IDLH) devices have an IDLH touch sensor mounted thereon having information unique to the specific IDLH device stored in the memory. Each of the instruments includes a receptacle for reading the information stored on touch sensors, a microprocessor having a memory portion for storing operating software and the information read by the receptacle, a display, and an operator interface for controlling operation of the operating software.

Abstract: A system for monitoring gases including sample, dilution, test, and control subsystems. The sample subsystem has a gas probe assembly defining a first end of a sample line and disposed in an area or adjacent to an object to be monitored. A sample pump in the sample line provides a positive motive force for drawing a sample and a sample pressure detector provides a sample pressure signal which is proportional to the sample flow rate. The dilution subsystem includes a dilution line having a first end vented to atmosphere. A dilution pump mounted in the dilution line provides a positive motive force for drawing the dilution air and a dilution pressure detector provides a dilution pressure signal which is proportional to the dilution flow rate. The test subsystem includes a test line having a first end in fluid communication with the second ends of the sample and dilution lines.

Abstract: The present invention is an instrument identification system and method for a confined space gas detector used to assure user safety conditions or to collect gas concentration and gas type data at a multitude of known predetermined locations. The system consists of information buttons with touch sensor contacts used for transferring ID type data comprising small stainless steel canisters containing computer memory programmed to store data pertaining to individuals and locations. The system further comprises a receptacle connector with electrical contacts coupled to a confined space gas detector for transferring information from the information buttons, where the gas detector, receptacle and receptacle contacts are contained within a portable integral housing.

Abstract: Automated test equipment is provided that performs quantitive tests and operational checks on respiratory protective devices including self-contained breathing apparatus (SCBA). The testing device is comprised of a bench-top instrument cabinet containing electronic, electro-mechanical, and pneumatic components, a test head with the likeness of human form attached on top of the instrument cabinet, a detachable computer keyboard, and a pneumatic manifold and hose assembly. With the present invention, a layman operator can determine the readiness of the SCBA equipment for service. The present invention can also be used as a diagnostic tool during maintenance procedures.
