Abstract: Technologies and implementations for a defibrillator electrode having communicative capabilities are generally disclosed.

Abstract: A system includes at least one sensor device in a compressed air line, at least one smart control valve in the compressed air line, and at least one processor to receive sensor data associated with the compressed air line from the at least one sensor device, store the sensor data, compare the sensor data from the at least one sensor device with a threshold to determine whether there is one of productive demand and non-productive demand from a demand source connected to the compressed air line, send a command to the at least one smart control valve based on the one of the productive demand and the non-productive demand from the demand source, and operate the at least one smart control valve based on the command to open the smart control valve when there is productive demand and close the smart control valve when there is non-productive demand.

Abstract: A silica cement blend is provided having insulating, fire retarding and high temperature characteristics that is capable of withstanding temperatures greater than 4000° F. without degradation of the concrete structure. In addition to its high temperature capabilities, the blend can be produced as ultra light weight to heavy weight concrete. Also provided are methods for reducing fire damage by coating interior/exterior walls, ceiling, and roofs of a building with a water based latex coating containing a fire retardant material and low heat conductivity silicas.

Abstract: A silica cement blend having an insulating, fire retarding and high temperature characteristic capable of withstanding temperatures ranging from ambient to greater than 40000 F without degradation of the concrete structure. In addition to its high temperature capabilities the blend can be produced as ultra light weight to heavy weight concrete. The silica based mixture when added to cementitious materials such as Portland cement, Class C Fly Ash, silica fume and other cementitious materials. Presented also are methods for reducing fire damage by coating interior/exterior walls, ceiling, and roofs of a building with a water based latex coating containing a fire retardant material and low heat conductivity silicas. Methods for painting internal/external walls, ceilings, and roof are also presented.

Abstract: A method of depositing tensile or compressively stressed silicon nitride on a substrate is described. Silicon nitride having a tensile stress with an absolute value of at least about 1200 MPa can be deposited from process gas comprising silicon-containing gas and nitrogen-containing gas, maintained in an electric field having a strength of from about 25 V/mil to about 300 V/mil. The electric field is formed by applying a voltage at a power level of less than about 60 Watts across electrodes that are spaced apart by a separation distance that is at least about 600 mils. Alternatively, silicon nitride having a compressive stress with an absolute value of at least about 2000 MPa can be formed in an electric field having a strength of from about 400 V/mil to about 800 V/mil.

Abstract: A valve assembly includes a first gate having at least one opening and a second gate having at least one opening, the second gate being spaced from the first gate. The valve assembly has first and second discs disposed between the first and second gates, each disc having at least one opening, whereby the discs are coupled together for simultaneously rotating between a valve open and a valve closed position. The assembly also includes a biasing element disposed between the first and second discs for normally urging the discs away from one another and toward opposing inner faces of the first and second gates.

Abstract: A non-rotational fitting assembly (10; 110; 210) is provided to prevent torsional forces of a nut (12, 112; 212) from being transmitted to a sealing face (16; 26; 246) of a fitting component (12; 22; 248). The assembly (10; 110; 210) includes at least one fitting component (22; 248) having a bearing face (28; 246) aligned orthogonal to the axis of the fitting component (22; 248). The assembly (10; 110; 210) also includes a nut (12; 112; 212) having a bearing face (36; 118) aligned orthogonal to the threads of the nut (26; 112; 212) and dimensioned for engagement with the bearing face (28; 246) of the fitting component (12; 22; 248).
