Abstract: An optical sheet suitable for use in a laminate comprising at least one glazing component. The optical sheet comprises a non-metallic multi-layer optical film that has multiple optical layers, and can be, for example, a solar energy reflective film (e.g., an infrared radiation reflective film).

Abstract: Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. Antishrinkage and antistatic additives are also added to the fibrous webs. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

Abstract: A video camera system includes: a video sensor providing image data; a low power imminent event detector coupled to the sensor which receives the image data from the video sensor and processes the received image data to detect changes in the image data and thereby detect an imminent event and produces an event signal on detection of an imminent event; and a main event processor also coupled to the video sensor to receive the image data, the main event processor being a higher power device than the imminent event detector, the main event detector having a dormant mode in which the main event detector consumes little or no power and a fully active powered up mode, wherein: the main event processor switches from the dormant mode to the fully active mode in response to the event signal.
Abstract: The present disclosure provides an article having (a) a substrate having opposing first and second surfaces; and (b) a conductor micropattern disposed on the first surface of the substrate. The conductor micropattern has a plurality of traces defining a plurality of open area cells. The conductor micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation. Each of the traces is non-linear and has a trace width from 0.5 to 10 micrometer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields.
Abstract: An inlet device is described herein for inserting a telecommunication cable into a telecommunications enclosure. The inlet device includes a housing, a retainer clip attached to the housing and a compression member. The housing can include a compressible portion at the second end of the housing. The retainer clip can secure the inlet device in a close fitting port of a telecommunication enclosure.

Abstract: A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.
Abstract: A system and method for volumetric metering on a sample processing device. The system can include a metering reservoir, and a waste reservoir positioned in fluid communication with a first end of the metering reservoir to catch excess liquid from the metering reservoir that exceeds a selected volume. The system can further include a capillary valve in fluid communication with the second end of the metering reservoir to inhibit liquid from exiting the metering reservoir until desired. The method can include metering the liquid by rotating the sample processing device to exert a first force on the liquid that is insufficient to move the liquid into the capillary valve, and rotating the sample processing device to exert a second force on the liquid that is greater than the first force to move the metered volume of the liquid to the process chamber via the capillary valve.

Abstract: A method of patterning a conductor on a substrate includes providing an inked elastomeric stamp inked with self-assembled monolayer-forming molecules and having a relief pattern with raised features. Then the raised features of the inked stamp contact a metal-coated visible light transparent substrate. Then the metal is etched to form an electrically conductive micropattern corresponding to the raised features of the inked stamp on the visible light transparent substrate.
Abstract: Techniques are described for inspecting a web and controlling subsequent conversion of the web into one or more products. A system, for example, comprises an imaging device, an analysis computer and a conversion control system. The imaging device images the web to provide digital information. The analysis computer processes the digital information to identify regions on the web containing anomalies. The conversion control system subsequently analyzes the digital information to determine which anomalies represent actual defects for a plurality of different products. The web inspection system may preferentially apply different application-specific defect detection recipes depending on whether a given anomaly is a repeating or random anomaly.
