Abstract: A system for detection of stress and deformation in a structural asset, for instance, one of reinforced concrete. An area on the asset may have a structure interface, such as a patch, attached to it with a fastening mechanism which may be a layer of an epoxy or other material, or be items such as screws, bolts, welds, or the like. One or more surface acoustic wave (SAW) strain sensors may be attached to the interface with an adhesive layer of epoxy or other material, or with mechanical items. Stress may be transmitted by the interface to the strain sensors. The sensors may be interrogated with a wire or wireless reader to obtain strain measurements. The measurements may indicate stress and deformations such as bulges and breaks in the asset. The measurements may also be a basis for determining location and extent of the stress and deformations.

Abstract: A system for heating a medical fluid includes a container including a fluid path including an inlet side and an outlet side. A broadband infrared radiation source including a power supply is coupled to a broadband emitter for emitting infrared radiation. The broadband emitter provides a focal location within the fluid path to heat the medical fluid to generate a heated medical fluid. A flow turbulence enhancing structure mixes the heated medical fluid to reduce temperature gradients therein. A fluid detector senses a presence of the medical fluid in the fluid path and generates a fluid sensing signal. A controller is coupled to receive the fluid sensing signal and has an output coupled to the power supply for controlling a power output of the power supply based on the fluid sensing signal indicating a presence of the medical fluid in the container.

Abstract: A system and method for heating a fluid for delivery of the fluid in the context of a particular medical, pharmaceutical, industrial or mechanical application. A cassette is associated with an application, such as, for example, a peritoneal dialysis machine. The cassette includes one or more outlet tubes for delivery of the fluid to, for example, a patient. A heating device is associated with the cassette, and heats a portion of the fluid prior to delivery of the fluid to the patient, thereby saving time and electrical power during delivery of the fluid to the patient. Additionally, a controller can be employed to control the heating range of the heating device and thereby provide a temperature of the fluid that is adaptable to the patient or a particular application.

Abstract: A strain gauge sensor system and method for measuring the strain in a member, such as a fiber rope, has a sensor target assembly having a plurality of magnets carried spaced apart by individual gauge lengths along the member. Position and trigger sensor devices are configured spaced apart along side a desired path of travel of the member. When the member is fed along the desired path of travel, the trigger sensor device, in response to magnetically sensing a passing magnet, triggers the position sensor device to read the position of an adjacent passing magnet. The strain in the gauge length is determined from the read position. RFID tags placed on the member between the magnets can be identified by an RF reader to identify a particular gauge length being measured. The system can include a deployment device for feeding the member along the desired path.
