Abstract: An optical fiber connector preloaded with an adhesive is provided. The optical connector includes a body having a passage with a first section extending inwardly from a first face of the body, a second section extending inwardly from a second face from the body, and a transition section located between the first section and the second section. The first section of the passage has a first width and the second section of the passage has a second width that is less than the first width. An adhesive composition is located within the transition section of the passage and is configured to bind an optical fiber to an inner surface of the second section following melting and solidification of the adhesive composition.

Abstract: A method of terminating an optical fiber involves providing a ferrule having a front end, a rear end, a ferrule bore extending between the front and rear ends, and a bonding agent disposed in at least a portion of the ferrule bore. The method also involves applying energy to heat the bonding agent. An end section of an optical fiber is inserted into the ferrule bore and through the bonding agent when the bonding agent is heated. The end section of the optical fiber includes a primary coating prior to insertion into the ferrule bore. During insertion of the end section of the optical fiber through the bonding agent, the heated bonding agent thermally removes at least a portion of the primary coating during so that the optical fiber can be secured in the ferrule bore with the bonding agent.

Abstract: A method for controlling a hybrid vehicle powertrain, where the powertrain includes a motor and an engine, includes providing a first motor torque in response to an engine start request. The first motor torque cranks the engine through a first compression event. The method additionally includes providing a second motor torque in response to the engine being cranked through the first compression event. The second motor torque is less than the first motor torque.

Abstract: Thermal removal of optical fiber coatings by insertion through heated ferrules to form ferrule assemblies for fiber optic connectors, and related assemblies are disclosed. An optical fiber includes a glass fiber, having a cladding and core, surrounded by a protective coating. By removing the coating at an end portion of the optical fiber, the end portion may be precisely positioned and secured within a ferrule to enable reliable optical communications. The coating may be thermally removed, or substantially thermally removed, by inserting the optical fiber through a rear opening of the ferrule which has been heated above a temperature sufficient to change the coating to a non-solid state. In this manner, the coating may be efficiently removed from the end portion of the optical fiber while being inserted into the ferrule bore of the ferrule to enable efficient forming of a ferrule assembly for a fiber optic connector.

Abstract: An optical fiber connector includes a ferrule configured to receive an optical fiber. The ferrule has a fiber bore and a storage location interior to the ferrule and adjacent to the fiber bore. The storage location comprises a funnel-shaped portion that is directed toward the fiber bore. An adhesive material is positioned in the storage location of the ferrule. The adhesive material is a dry and solid material.

Abstract: Systems and methods for learning torque estimate errors and updating torque estimation models are presented. In one example, torque errors are learned during an engine shut-down, after a disconnect clutch coupled between an engine and an electric machine has been released. An updated torque estimation model is then used to control torque during subsequent engine operation to improve drive feel and vehicle performance.
