    摘要: A method of shaping an ophthalmic lens to have a desired outline with a machining device including a blocking support for the ophthalmic lens and at least one first machining tool, the method includes: obtaining an inner cutting limit for the first machining tool; defining an initial blocking position for the ophthalmic lens and its desired outline; calculating whether at least a portion of the desired outline presents a non-zero intersection with the inner cutting limit; defining as the final blocking position either the unchanged initial blocking position if the calculated intersection is zero, or else a blocking position that is modified relative to the initial blocking position so that the desired outline as repositioned using the modified blocking position does not present an intersection with the inner cutting limit associated with the first tool; and blocking and shaping the ophthalmic lens with the desired outline.

    摘要: An apparatus and method for automatically placing a sheet of glass in a glass frame. The apparatus includes a frame, a carriage, a first gripper, and a second gripper. The carriage is movably mounted to the frame to automatically move between a first position where the carriage is by a stack of glass sheets on a glass rack to a second position where the carriage is by the glass frame. The first gripper is movably mounted to the carriage and moves relative to the carriage to automatically engage the sheet of glass from the stack of glass sheets on the glass rack at the first position of the carriage and to automatically release the sheet of glass at the second position of the carriage. The second gripper automatically engages the sheet of glass when the first gripper automatically releases the sheet of glass at the second position of the carriage, and then automatically places the sheet of glass in the glass frame.

    摘要: Systems and apparatus are provided for capacitor segments for use in a vehicle. A capacitor segment comprises an inner conductor configured to receive a first potential and having a generally L-shaped longitudinal cross-section. An outer conductor is configured to receive a second potential, and is electrically insulated from the inner conductor. The outer conductor comprises a first section having a generally L-shaped longitudinal cross-section aligned with the inner conductor, and a second section coupled to the first section and having a generally L-shaped lateral cross-section. The second section and the inner conductor define an inner region. A capacitor is located in the inner region and coupled to the inner conductor and the second section. The capacitor segment is configured such that current flows through the capacitor in a first direction, and current flows through the second section in a second direction that generally opposes the first direction.
