Abstract: A gas analysis device includes a canister with a cavity that is configured to receive a gas sample. A sensor is in fluid communication with the cavity and analyzes a portion of the gas sample that is received from the canister. The device also includes a blower assembly in fluid communication with the sensor. The blower assembly is configured to selectively draw a portion of the gas sample from the canister past the sensor so that the sensor is exposed to the portion of the gas sample.

Abstract: A sensor module includes a substrate with a slot formed therein. A sensor is mounted to the substrate and spans the slot. A first cover is disposed on a first side of the substrate and covers at least a portion of the slot. The first cover comprises a first aperture and a second aperture in fluid communication with the slot. The sensor is disposed between the first and second apertures.

Abstract: A device for capturing a breath sample has a mouthpiece with a chamber that receives a breath sample through a breath inlet aperture. The device further includes a pump assembly with a pump that draws a portion of the breath sample from the chamber and discharges the portion of the breath sample to the sensor.

Abstract: A method for analyzing a gas sample includes the steps of providing a gas sample to a sample canister and heating a sensor to a predetermined resistance. The method further includes the steps of operating a fan at a predetermined speed, and moving a valve to a measurement flow position. When the valve is in the measurement flow position, the fan draws a portion of the gas sample through the valve to expose the sensor to the gas sample.

Abstract: A decal is suitable for application to an aircraft structure that is covered with an incompletely cured base coat of paint. The decal has a polyester film with an adhesive applied to a first side. A release layer is applied to the polyester film and comprises a pattern engaging the adhesive to form a plurality of grooves in the adhesive layer. When the decal is applied to an uncured base coat of paint, offgasses formed during curing and drying of the base coat escape from beneath the decal through the grooves.

Abstract: A first embodiment of a disclosed breath analyzer detects a particular breath component in a breath sample. The analyzer includes a housing defining an interior cavity and having an inlet aperture for receiving the breath sample and an outlet aperture. A sensor is disposed within the cavity for sensing the component of the breath sample. An anemometer circuit is associated with the sensor and measures a rate of flow of the breath sample within the housing. The analyzer further includes a controller operatively connected to the sensor to receive breath component information sensed by the sensor.

Abstract: A breath analyzer detects a breath component in a breath sample. The analyzer includes a sensor for sensing the breath component and a temperature control system integrally formed with the sensor. The temperature control comprises a resistive temperature device configured to heat the sensor to a predetermined temperature. The resistive temperature device also senses the temperature of the sensor. A controller is operatively connected to the sensor to receive breath component information sensed by the sensor.

Abstract: A membrane switch (10) is disclosed having a bottom membrane (12) with an upper conductive surface (16), a top membrane (14) with a lower conductive surface (18), and an intermediate spacer (20) disposed therebetween. The intermediate spacer includes a central aperture (24) and is formed of an intermediate substrate (21) having a lower surface (26) and an upper surface (28). First y-axis electrodes (30A, 30B) including first contact portions (31A, 31B) and second x-axis electrodes (34A, 34B) including second contact portions (38A, 38B) are both formed on the upper surface of the intermediate substrate. The intermediate spacer further includes an upper adhesive layer (45) including predefined first apertures (50) adapted to overlie the first contact portions of the y-axis electrodes and predefined second apertures (47) adapted to overlie the second contact portions of the x-axis electrodes, and a lower adhesive layer (43).

Abstract: A repositionable mouse pad (20) for a computer having an input device (30) operatively connected to the computer. The mouse pad includes a tracking surface (22) having upper and lower surfaces (26) and (28). The upper surface being textured for precise tracking of the pointing device. The mouse pad also includes an attachment member (24) bonded on the lower surface of the tracking surface and includes an adhesive (34). The attachment member is bonded to the lower surface of the tracking surface such that the adhesive side faces outwardly away from the tracking surface. The adhesive side is renewable to restore its adhesive strength by cleaning the adhesive side.

Abstract: A flexible-touch keypad (100) is backlit by an electroluminescent layer (118) that overlies an actuator layer (108) and a circuitry layer (102). The actuator layer (108) includes posts (112A) protruding through apertures (120) in the electroluminescent layer (118) and extending upward toward a translucent flexible surface layer (124). The flexible surface layer (124) is coated with an opaque layer (206), which is etched to form indicia (130). The protruding post (112A) is translucent and functions as a light pipe, directing light upward from the electroluminescent layer (118) and through the translucent surface layer (124) with a substantially uniform light intensity, the light being visible through the etched indicia (130). When a key (128A) on the surface layer (124) is depressed, a corresponding post (112A) is urged downward toward the circuitry layer (102). A conductive pill (116A) attached to the post (112A) contacts a switch area (104) on the circuitry layer (102), thereby completing a circuit.

Abstract: A membrane switch (10) having a top membrane (12) with a lower conductive surface (16), a bottom membrane (14) with an upper conductive surface (18), and a dielectric intermediate circuit spacer (20) disposed therebetween. The intermediate circuit spacer includes a central aperture (24) and defines upper and lower surfaces (28 and 32). First y-axis electrodes (26) are formed on the upper surface of the intermediate circuit spacer, and second x-axis (30) electrodes are formed on the lower surface of the intermediate circuit spacer. Conductive adhesive (58, 64) is applied between the intermediate circuit spacer and the top and bottom membranes to secure the intermediate spacer in place with the x- and y-axis electrodes in electrical contact with the top and bottom membranes, respectively.
