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 methods are provided for monitoring current in an electric motor. An electrical system includes a (DC) interface, an electric motor, an inverter module coupled between the DC interface and the electric motor, a first current sensor between a first phase leg of the inverter module and a first phase of the electric motor to measure a first current flowing through the first phase of the electric motor, a second current sensor between the first phase leg and the DC interface to measure a second current flowing through the first phase leg, and a control module coupled to the first current sensor and the second current sensor. The control module is configured to initiate remedial action based at least in part on a difference between the first current measured by the first current sensor and the second current measured by the second current sensor.
