Abstract: Polycarbonate polymers comprising non-aromatic cyclic groups bonded with carbonate linking groups are described. A portion of the non-aromatic cyclic groups comprise a substituent having siloxane repeat units. Representative formulas of the substituents having siloxane repeat units include —CH2—CH2—Si(R4)2—(OSi(R4)2—R5, and —CH[Si(R4)2—(OSi(R4)2)m—R5]—CH3; wherein m is the number of siloxane repeat units; and R4 and R5 are independently alkyl, aryl, aralkyl or aralkylene. The polycarbonate polymer C typically comprises a high concentration of carbonate linking group, for example in an amount of at least 85 or 90 mol % or greater N based on the total linking groups of the polymer. Also described are compositions comprising the polycarbonate polymer and methods of making.

Abstract: Containers (100), for example boxes, envelopes, mailers, and the like containing one or more deployable cushioning sheets (1500) are disclosed. The deployable cushioning sheets (1500) are connected to at least one wall of the containers (100) and can be deployed to be partially outside of the container for cushioning, for example by wrapping, an object (1600) to be packaged. The deployable cushioning sheets (1500) can contain, for example, paper, cardboard, foam, bubble film, or the like, or they can contain combinations of different types of materials. The containers (100) are useful in methods of packaging, storing, and shipping, among other uses.

Abstract: A surface conditioning article comprises: a fabric backing having first and second opposed major sides: a lofty open nonwoven fiber web comprising entangled fibers disposed on and secured to the first major side of the fabric backing; and abrasive particles secured to the lofty open nonwoven fiber web by a binder material disposed on the first major side. At least some of the entangled fibers extend through the fabric backing from the first side to the second side. At least one raised feature comprising an organic polymer is disposed on a minor portion of the second major side of the fabric backing. The entangled fibers extending through the fabric backing have an average diameter and at least one raised feature has a height of at least 8 times the average diameter. A method of making the surface conditioning article is also disclosed.

Abstract: Techniques, systems and articles are described for preparing electrical cables for connections to a power grid. In one example, a cable-cross-section-measurement tool includes a housing defining a cavity, wherein the housing is configured to position an end-face of an electrical cable within the cavity; a camera disclosed within the cavity of the housing, wherein the camera is configured to capture an image of the end-face of the electrical cable; and a telecentric lens optically coupled to the camera, wherein the telecentric lens comprises a non-angular field of view configured to reduce, in the image, distortion from parallax associated with at least one portion of the end-face of the electrical cable that is oriented at an oblique angle relative to an optical axis of the telecentric lens.

Abstract: Projection systems and components thereof are described that are well suited to miniaturization. These systems and components may use one or more of the following features: a folded optical path, as in a reflective cavity or a beamsplitter; an illumination beam that is converging at the place where it impinges upon the spatial light modulator; a beamsplitter that uses opposed prisms of substantially different sizes; a beamsplitter whose obliquely disposed partial reflector defines a first rectangular reference space, and where at least a portion of the light source or at least a portion of the projector lens is disposed within such first rectangular reference space; a system in which a ratio of areas of the first rectangular reference space and a second rectangular reference space is within a specified range, where the second rectangular reference space is just large enough to encompass the optical components of the projector; a system in which the projector lens is small compared to the spatial light modulator.
