Abstract: Methods of correlating a monitoring device to the service life of a filter cartridge include providing a monitoring device, and calibrating the monitoring device to correspond to the service life of a filter cartridge. The monitoring device comprises a demand substance within a receptacle, a sensing element with a detection point, a reader for the sensing element, and a fluid delivery device. Calibration includes determining the ratio of the residence time of the monitoring device to the residence time of the filter cartridge, and utilizing the ratio to correlate the response of the sensor within the monitoring device to the service life of the filter cartridge. The response of the sensor is correlated to the service life of the filter cartridge by control of the fluid delivery parameters of the fluid delivery device.
Abstract: The disclosure generally relates to a film roll core used for winding a polymeric film around, an apparatus for winding the polymeric film on the film roll core, a process of winding the polymeric film on the film roll core, and a rolled film on the film roll core.

Abstract: Laser-personalizable security articles include a multi-layer security document and an optically transparent processing tape. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser. The optically transparent processing tape sufficiently wets out on the misconstructured surface to render the microstructured surface invisible to a writing laser.

Abstract: An apparatus includes a receiving module, a conversion module, first and second rollers, a motor, a forcing member, an implement, and a cutting head. The receiving module receives a desired weight value to correct an imbalance of a wheel/tire assembly. The conversion module converts the desired weight value to a corresponding first amount of a wheel weight material. The first and second rollers engage first and second opposing sides of the wheel weight material. The motor drives the first roller according to the first amount. The forcing member presses the second roller in a first direction that forms an angle with an axis of the first roller. The implement selectively forms a mark on the wheel weight material. The cutting head is selectively actuated to separate the first amount from the wheel weight material.

Abstract: A system for monitoring temperature of an electrical conductor (31) enclosed in at least a (semi)conductive layer (13) comprising: a passive inductive unit (20), and a transceiver unit (40) and a control unit (50). The passive inductive unit (20) includes at least one temperature sensitive component and is configured to have a resonance frequency and/or Q value that vary with temperature of the electrical conductor (31). The transceiver unit (40) is configured to be electromagnetically coupled to the passive inductive unit (20) and to send out a signal representing the resonance frequency and/or Q value of the passive inductive unit (20). The transceiver unit (40) is further configured to communicate with the control unit (50) which ascertains the signal representing one or both of the resonance frequency and Q value, and which determines a value of the temperature of the electrical conductor (31) based on the ascertained signal representing one or both of the resonance frequency and Q value.

Abstract: Articles are provided, having a first substrate and a polymeric structure wrapped around the first substrate at least two full circuits. The polymeric structure has a length, a width and a thickness, and comprises a crosslinked polymeric layer uniaxially oriented in the width direction at a draw ratio of at least 1.2:1. The length is greater than the width. A method is also provided including providing a polymeric structure, wrapping the polymeric structure around a first substrate at least two full circuits, positioning the polymeric structure at least partially within an aperture defined by a second substrate, and subjecting the polymeric structure to an elevated temperature above the transition temperature of the crosslinked polymeric layer and below the degradation temperature of each of the components in the polymeric structure. The thickness of the polymeric structure increases, creating at least a partial joint between the first substrate and the second substrate.
