Abstract: An automated electric vehicle charging station. The charging station can include a frame to which a vehicle can park in proximity to receive an electric charge. The frame is at least partially underneath the vehicle. The charging station can include an alignment indicator and a charging indicator to alert an occupant of the vehicle to a vehicle alignment status and a vehicle charging status. When the vehicle is parked in a charging position, an electronic charging unit automatically determines a receiving location on the vehicle where the vehicle can receive an electric charge. A charging plug can be stored in the frame and can be actuated out of the frame and travel in multiple directions to the receiving location. Electric charge can then be transferred from the charging plug to the vehicle. When the vehicle is finished charging, the charging plug can be actuated to return to the frame.

Abstract: This invention is directed to a structure and a method of sealing the structure as it is manufactured. The method uses a combination of thermoplastic sealants in the form of films and a substrate encapsulated tape.
Abstract: A method of encapsulating an electronic component. The method includes applying a first layer of an encapsulating composition onto an electronic component from an applicator roll, the electronic component being disposed on a substrate. The applicator roll comprises an outer surface and is spaced apart from the electronic component such that a gap exists between the applicator roll and the electronic component. The gap controls the thickness of the first layer of encapsulating composition. The first layer of encapsulating composition encapsulates the electronic component on the substrate. An interface between the surface of the electronic component and the encapsulating composition being substantially free of voids.

Abstract: A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.
