Abstract: A drive belt includes a foamed undercord layer having void spaces located throughout the foamed undercord layer. The void spaces extend from a backing layer of the undercord layer to an exterior surface of the backing layer, and may include some void spaces at the exterior surface that are open to the external environment. The foamed undercord layer may exhibit a 20% reduction in specific gravity as compared to an unfoamed version of the undercord layer. The manufacturing process for making the foamed undercord layer can include incorporating foaming agent in the undercord layer such that the undercord layer both foams and cures when heat and pressure are applied to the undercord layer. The foamed drive belt incorporating the foamed undercord layer may exhibit reduced bending stiffness and improved energy efficiency.

Abstract: A self-aligning power transmission belt, which may be used in conjunction with a corresponding sprocket, and systems incorporating the self-aligning power transmission belt are described. The self-aligning belt includes a tooth configuration that can eliminate tracking error in belt applications. In some configurations, the self-aligning belt includes two or more rows of teeth, with the teeth in one row being offset from the teeth in a second row.

Abstract: Endless belts, such as for use with e-bikes and other personal mobility systems such as standard bicycles, wheelchairs, scooters including electric scooters, and other systems that utilize a belt for transmitting power to impart motion to the system. The belts are particularly suited for inhibiting “tooth jumping” during use, having a curvature coefficient of no more than 0.01%, and in some embodiments less than 0.005%, with a compressibility coefficient of no more than 0.00075. The belts can utilize reinforcing cords, such as carbon cords, which when incorporated into the final belt, some cords have an open porosity of 10 vol-% or less, in some embodiments 5 vol-% or less.

Abstract: A device for controlling industrial belt tracking with a first cylindrical pulley segment having a central opening and a plurality of teeth formed on the outside diameter; a second cylindrical pulley segment having a central opening and having a plurality of teeth formed on the outside diameter; and a flange ring. The flange ring being disposed between the first cylindrical pulley segment and the second cylindrical pulley segment such that the flange ring, the first cylindrical pulley segment and the second cylindrical pulley segment are coaxially aligned. Further, the flange ring is shaped and sized such that the outer diameter edge provides a flange perpendicular to the plurality of teeth formed on the outside diameter surface of the first cylindrical pulley segment and the second cylindrical pulley segment and generally radially aligned with the plurality of teeth formed on the outside diameter surface of the first cylindrical pulley segment and the second cylindrical pulley segment.

Abstract: An OFET includes a thick dielectric layer with openings in the active region of a transistor. After the field dielectric layer is formed, semiconductor ink is dropped in the active region cavities in the field dielectric layer, forming the semiconductor layer. The ink is bounded by the field dielectric layer walls. After the semiconductor layer is annealed, dielectric ink is dropped into the same cavities. As with the semiconductor ink, the field dielectric wall confines the flow of the dielectric ink. The confined flow causes the dielectric ink to pool into the cavity, forming a uniform layer within the cavity, and thereby decreasing the probability of pinhole shorting. After the dielectric is annealed, a gate layer covers the active region thereby completing a high performance OFET structure.

Abstract: A method and system for providing a twin well in a semiconductor device is described. The method and system include masking a first portion of the device such that a second portion of the device is exposed. A sacrificial layer has a first portion on the first portion of the device and a second portion on the second portion of the device. In one aspect, an oxidation stop layer may be below the sacrificial layer. The method and system include implanting a first well in the second portion of the device, exposing the first portion of the device after the first well is implanted, and oxidizing the second portion of sacrificial layer after the exposing. The method and system further include implanting the second well in the first portion of the device after the oxidizing and planarizing the device after the second well is implanted.
