Title: Systems for recording data monitored during the manufacture of molded ophthalmic lenses and for recording data ophthalmic lenses manufactured in a molding process, and methods thereof
Inventor: LEPPER JOHN
IPC: G06Q50/00
Filed: 2003-04-11
Granted: 2007-12-11
Abstract: These and other objectives are attained with a method and system for recording data monitored during the manufacture of molded ophthalmic lenses. This method comprises the steps of identifying a set of process parameters used in said manufacture, identifying an associated value range for each of the process parameters, and monitoring each of the process parameters during the manufacture of the lenses. If, during the manufacture of one of the ophthalmic lenses, one of the process parameters moves outside the associated value range, then that lens is rejected. However, if, during the manufacture of one of the ophthalmic lenses, all of the process parameters stay within their associated ranges, then that lens is identified as acceptable, and a device history record is made for that lens. This device history record includes a reference code for identifying the set of process parameters. A database, referred to as a shadow table, may be used to protect the integrity of data recorded during, or relating to, the manufacture process. In accordance with this feature, a shadow table is formed, and data items from device history records are copied into the shadow table in response to the occurrence of predefined events. For example, these predefined events may include whenever anyone, or anyone outside a group of identified individuals accesses the device history record to perform predefined operations, such as alter or delete, on the data in the device history record.

Granted: 2004-11-21
Abstract: To provide a pump unit capable of obtaining high discharging pressure by a motor having comparatively small torque, and decreasing noise/vibrations at the time of large flow operation. A first pump 1 made from a gear pump of a small capacity, and a second pump made from a gear pump of a large capacity are directly united by a variable speed motor 3 controlled in the number of revolutions by a control device 4. In a first mode, a discharge line 5 of the first pump is diverted from a discharging line 8 of the second pump, and the first pump is unloaded to carry out constant horsepower operation, thereby making a discharge fluid have high pressure by comparatively small torque. In a second mode, the discharging line 5 of the first pump is merged with the discharging line 8 of the second pump to carry out the constant horsepower operation, thereby discharging the large flow amount of the discharge fluid at a comparatively low number of revolutions. When the number of revolutions of the variable speed motor is lower than a specified value, a switch valve 6 is switched from a merging state to a diverting state. When discharging pressure is lower than a specified value, the switch valve 6 is switched from the diverting state to the merging state.
